Inside an ozone room deodoriser.

I find ozone quite an interesting gas. It can be generated on demand electrically by either plasma or UVC and has a bleach-like odour and a very strong oxidising effect.
The oxidising effect is used to neutralise airborne odours like cigarette smoke and undesired odours in public toilet facilities. It has to be used in moderation, since too much ozone can cause irritation.
Ozone is not a fix for the mouldy smell associated with furnishings that have been damp for a period of time. The best fix there is to remove the affected material.
Ozone is also used as an alternative to detergent in some laundry equipment due to its ability to clean and sterilise fabrics when diffused in water. Some machines offer a dry cycle too that tumbles the clothing in ozone to freshen it up.
The gas is controversial in that some people believe that low levels are safe, while others believe that any level is harmful. It does occur naturally in nature, notably after a thunderstorm.
Some materials like rubber can be damaged by overexposure to ozone through rapid oxidation. Laundry equipment using the gas has to be made from materials like stainless steel and silicone.

About 20 years back, I was working on the Police Department. One of our squad cars had been used to transport a skunk to the vet after dispatching him with the scatter gun. Well it was supposed to go to the vet but it was near the end of shift and the officer left the body of the skunk in the trunk. The car sat in the shed for over a week before it's rotation came up once more. I was the unlucky one to discover the officers screw up. Man that stench was so bad it nearly gagged me, made my eyes water it was just horrid. Needless to say that car was not used that night, the next day I had the City crew remove the skunk and dispose of it, then called a fellow who steam cleaned carpets and such. Well he had an ozone machine, much bigger then the one you disassembled. He brought it over and placed it in the passenger seat of the squad then left it for a day. The next day, the car was completely clean, not a bit of dead skunk remained, it smelled as fresh as a springs morning on the lake. Wonderful devices these ozone makers.

[@WineScrounger]

Jerry Ericsson Shawn Woods, trapper and hunter extraordinaire, tried cooking and eating a skunk to see if it was any good. Spoiler: It’s not good at all

[@johnpossum556]

"Skunk in the trunk" would be a good name for a rock band.

[@McNair1952]

In this case, it would be helpful to other bigclive fans if you would mention the country you are in, it is the world wide web after all. From Scotland, thankfully a skunk free zone.

[@johnpossum556]

LOL! That reminds me we once had the family pet dog slide under the electrified fence of the nearest farm and roll in cow pies and skunk. We washed him down in the lake in lemon dawn and later tomato juice. It still barely touched the stench of having to ride home 6 hours with the dog right in between me and my sister. Uff Da!

[@rich1051414]

Tomato juice only somewhat works as the volatile chemicals don't get fully neutralized by reacting with acid. I think they even had a mythbusters episode about it. Concentrated citric acid doesn't work either, and will only made all your minor cuts burn like the surface of the sun. Ozone is different, ozone is a super oxidizer, and oxidation will always reduce the potency of volitile smells. It only 'smells fresh' because it is actively neutralizing all the smells in your nose, leaving you with essentially no smell, which the brain interprets as a 'fresh smell'. Kind of like how you can taste water. You are actually tasting 'no saliva'. Kind of like if you stare at a bright yellow image, then look at a white wall, it will look purple. You really don't want to breathe the stuff. A powerful oxidizer has to kill sensitive lung tissue.

[@BlargKing]

I work at a hotel that has one of these to deodorize the rooms. Apparently up until I started working there, they would put the machine in a room and run it while still cleaning inside the room. Nobody working there knew how bad ozone is until I told them all. Workplace safety is apparently non-existent.

[@jawr1215]

Have one of these 'industrial' units, but with the plate not the tube. Absolutely fantastic. Stops mould problems, gets rid of smells completely. Great for vintage clothes too. I set it for an hour with fans on for circulation and it does my whole flat while I'm at the pub. Lend it to friends and family often ('new' cars, new houses etc). Id consider it as essential as a hoover. Just dont be in the same room when its on, and give it plenty of time to dissipate before entering the room/area. Combined with a hepa air filter has massively helped my partners athsma symptoms.

[@bigclivedotcom]

In Japan you get the clothes freshening machines that tumble the clothing in ozonated air.

[@nw8000]

What model do you have??

[@180bst]

Being a TV serviceman the strong smell of ozone was always present in a dusty/damp TV at the EHT on the tube when working on them. Also during a still thunderstorm you can sometimes catch a whiff of it and is so refreshing as you say clean and sterile smelling

[@LongPeter]

I remember seeing an unplugged CRT tv flashing during a lighting storm when I was a kid. Rather disconcerting, being too young to understand why it was happening.

[@stonedsavage7814]

Peter Charlton same here except that when i touched the glass it was giving me tiny miniscule static shocks that felt great and made my hair stand up oh man those were the good days.

[@LongPeter]

Oh man, wiping the layer of static off of the monitor and then lightning bolting the person next to you was the best part of anything computer-based in early highschool.

[@crystalsoulslayer]

Be sure to supercharge your zappy powers by degaussing the monitor before collecting the static. Also, if the jerk who sits next to you leaves it unattended, be sure to take the ball out of his mouse.

[@crystalsoulslayer]

Excellent. :D I was in high school in the late 00s, so they'd pretty much figured out how to keep the student computers from doing anything too interesting by then. Though they couldn't really restrict USB devices much because people would bring assignments on them... a certain amount of mischief was made using wireless mice and keyboards.

[@LatitudeSky]

I've owned a similar machine and it works well but the ozone is very damaging to rubber and plastics. It makes them extremely brittle. Where I work, we have a number of machines that emit ozone in the course of operation. They have extensive filters to control the emissions however... We use a lot of rubber bands in our work. Every machine has a tub of them. New rubber bands out of the package stay new for less than a day. They age immediately. By two or three days, they are dried out and becoming brittle and will snap easily. After a week, they've changed from rubbery gold to brown, much tougher. Very little rubber flexibility. After a month or two, they look like they are 100 years old and shatter. The ozone just wrecks them. Worker's shoes also take a huge hit. A new pair of shoes will last maybe three months and it's just done. Soles crumble. And this is with suitable filtering! The machines themselves only survive it because we have constant maintenance to replace affected parts. And still, they regularly break down due to plastics and rubber parts disintergrating.

[@mikeguitar9769]

Have you tried silicone rubber, either as a substitute or as a coating?

[@deaultusername]

If it had such a rapid effect on materials in such low concentration from being filtered, what was it doing to the workers under continuous exposure to it.

[@NinoJoel]

Sounds like there is something else besides the ozone. Im using high concentrations of ozone regularly to clean my house or cara and I never had any problems with plastics or rubber seals.

[@savirien4266]

My older than dirt ozone "filter" only uses air between the grid-like electrodes. No sparking, but in the dark you can see the corona. These are really nice for keeping your clothes closet and the clothes inside smelling fresh. It's also really nice for keeping that fear in the back of your head that it might burn your house down someday.

[@ALAPINO]

I remember in the 90s when ozone generators were all the rage... with lovely innocuous plastic wood enclosures for gran's living room. ;)

[@ninjamaster3453]

We use heavy duty ones to mitigate after water damage and clean up. Helps a whole lot. Don't stay in the room with one though

[@TheFurriestOne]

Ozone is also used in some cleaning units for use with CPAP/BIPAP machines, keeps down infection and lengthens times between manual cleaning with soap and water (which can't be used on the main unit anyhow). Thanks for the look inside!

[@christianuy5791]

TheFurriestOne interesting. I wondered how the big machines are cleaned since soap water and chemicals can’t be sprayed in the machine. Ozone is awesome

[@astrangeone]

I've seen that on CPAP machines. Looks neat.

[@mattc9009]

Funny enough Phillips have issued a recall of their cpap machines due to lose foam, cleaning with an ozone generator makes the problem worse they say.

[@CLaw-tb5gg]

Something Clive missed: oxygen (provided it's not been ionised) makes two bonds with other things, like in water, H2O, where each of its bonds is made with a hydrogen atom. The more bonds an atom has with another atom the more stable that bond is - because it's like more glue between them, meaning it's harder to pull them apart - and usually oxygen shares both its bonds with something (unless that something can only form one bond, like hydrogen in water), like another oxygen atom, because that's oxygen's most stable state. Atoms always want to become more stable; think of stability like gravity, with things always falling downwards into more stability unless some energy is put into them from below, pushing them upwards towards less stability. This is what kind of happens with ozone: electrical discharge, or oxygen being hit with high-powered cosmic ray photons in the upper atmosphere, imparts enough energy into O2 to rip the atoms apart. This means they go into a high-powered unpaired state, which then "falls down" into bonding again into O3. This only has single bonds, with each oxygen paired to two other oxygens, so it then "falls down" again into O2, where it has a more stable double bond with only one other oxygen. Before everyone picks this itself to bits I know this is a little overly simplified, because I don't want to write an entire essay here.

[@UpLateGeek]

I bought a cheap Chinese ozone generator off ebay for experimentation porpoises. It consists of a similar "transformer" which powers an enclosed corona discharge unit that has hose barbs moulded into plastic body of the unit, which is connected to an aquarium air pump via silicone tubing, and also an outlet hose. When I first powered it on, it rattled and vibrated very noisily, and when I opened it up I found the aquarium air pump had become dislodged. It was only held on with hot melt glue, so I just gooped some more on and pressed it back in to place. It seems to work ok, but produces a highly noxious emanation. Anyway, I was going to use it for experimentation in retrobriting some vintage computers and stuff, as an alternative to hydrogen peroxide. The 8-Bit Guy had some limited success with sealing the item to be retrobrited in a ziplock bag with ozone, so I was going to try bubbling it through water. Unfortunately my experiments will have to wait until spring. Apparently heat plays a big part in the chemical reactions, but it's only reaching around 16-19°C during the day here in Sydney.

[@EpicATrain]

I'm so glad you did this video!!! We bought an Ozone generator last week and started using it for a few projects. :)

[@twocvbloke]

Apparently they use these in used car sales places to remove (at least temporarily) the stench of smoke in cars they've traded in, so when they sell the car to a potential mug, erm, I mean customer, the car smells "clean"...

[@calicantdrive]

Used properly, it's definitely not temporary, it actually oxidizes away the compounds creating the odor. Chemical deodorizers are temporary, or course.

[@calicantdrive]

You think the solid particles that make up that smoke can penetrate the fabric more deeply than ozone, which is a gas? Mind you, it is helpful to get as much of that out of the fabric as possible before using the ozone generator, but the ozone will literally oxidize the smoke away.

[@phils4634]

These are also used in Mortuaries, and Pathology Departments. I think they are also popular with the specialist teams who clean up houses after the occupant(s) have an "unwitnessed death" - the sort of event where no-one realises they have "departed" until things become "somewhat aromatic" (especially during the warmer months) . . . . . .

[@eddiespencer1]

They also use them in new-car dealerships and most other retail places because people really do stink.

[@augmenseke6131]

What? This odour destroying tool developed for detailing cars gets used to remove odours from used cars? Noooooo. That’s soooo shady.....

[@cadburybunny]

Used to work with ozone machines in my previous jobs and it's kind of neat to see the insides of them now.

[@Rapscallion2009]

I remember the smell of Ozone from early laser printers. When, the stunk of it when they didn't small of melting plastic, burning paper, charred flesh or burning electronics.....

[@bigclivedotcom]

Yeah, the early photocopiers and laser printers were exciting beasts.

[@lazaglider]

Rapscallion2009 Ahh, now a memory from childhood makes sense. There was a photocopier in the school library that always produced an interesting smell when in use. We always used to say it was ozone, without really knowing how or why. Sounds like we were on the money. Nice smell from what I recall.

[@WaltonPete]

lazaglider Maybe I'm REALLY old, or perhaps my early schools were crap, but our school copier used carbon paper, smelly volatile chemicals and man / woman power to produce paper copies! I always loved the distinct smell coming from freshly minted copies, which probably made us all as high as kites!

[@Demolishionist]

I used to love the smell of mimeograph copies. That pungent purple ink, a smell you can't forget.

[@millomweb]

@@WaltonPete Prob not 'carbon paper'. It'd be a duplicator - with a 'master' affixed to a drum and a handle on the side to crank the machine. Posher ones were electrically driven. I've seen the results in 'pink' and 'blue' and reasonably pungent !

[@MichaelFlatman]

1:40 wow that's a very good drawing of a spark!

[@WaltonPete]

Michael _Howto&tech Clive's had years of practice!

[@TheGreatAtario]

When I was a kid, I had a toy electric train set - O-scale, three-rail. It sparked quite a lot, so the scent of ozone always reminds me of that set

[@MadScientist512]

I love the smell of ozone in the morning! Seriously though, I used to build all manner of high voltage generators back in high school, scrounging car coils, TV flyback transformers and disposable camera flash units, so the smell of ozone brings back some old memories for me.

[@QF2653]

My wife bought me one of those CPAP machine cleaners, glad I returned it, I wouldn't want to be breathing 'degraded plastic's. Might cause worse problems than snoring does.

Reno doesn’t get it. That’s funny.

[@will_doherty]

I appreciate that this is an old vid. I've been in numerous public loos in the Uk over the years (sometimes it's unavoidable!) where they have the ozone generators high up on a wall. There are two reasons why they're always immediately identifiable - firstly the buzz of the generator is unmistakeable, and secondly the strong stench of ozone.I had thought it curious, even when I was a kid, if it was safe. It seems it's not, but it never seemed to be an issue to those "in control"...

[@28YorkshireRose12]

Hmm, old televisions with dodgy EHT connections, or in a damp room - no mistaking the ozone there!

[@manolisgledsodakis873]

Siemens used to use "Hellfax" fax machines that "printed" dots on the paper by applying high-voltage pulses to a needle that traversed the metal platten. The resultant corona discharge was efficaceous in removing old farts from the office. (I was one of them - it made me gag.)

[@AdmiralPreparedness]

The shipboard radar that I operated and maintained while in the US NAVY produced tons of Ozone because of the high voltage transmitter stages needed to radiate RF energy a very long distance!

[@williamthomasmi10]

Love you clive, so informative. I've had a moldy smell coming from my AC lately, was wondering if this would work. Right there in the description, no it will not, thank you very much ! :P

[@bigclivedotcom]

Some air duct systems do use UVC lamps for ozone sterilisation of the air.

[@japonicaren]

Look for UVC 253.7nm or 254nm bulbs/tubes. They are known as 'no ozone' UVC emitters on AliExpress. The same seller will often have an 'ozone' type UVC bulb which works at below 180nm (wavelength). Even the no ozone types give off a tiny amount of ozone but nowhere near as much as the ozone type bulbs. These would probably be safer to clean an air conditioner without degrading rubber/plastic parts. I had hoped to get one of the corona discharge open plate devices and sit it on top of the air conditioner intake with a timer set for 30 minutes to get rid of mold etc but reading through the comments it looks like a no no. Just understand that the no ozone type bulbs can only clean line of sight. So you won't be able to clean the tubing innards etc. I'm hoping you could at least clean the spinning drum and housing of the indoor end of the air conditioner system.

[@superdau]

I was working in a government office for a short time. They had a cramped archive room that also contained two big copying machines. That room was really hard to stay in, because of all the ozone they generated. There was even a guy working in there who was also a heavy smoker (not in the archive). I guess he didn't notice the sting anymore anyway. I wonder if the ozone would damage the files (consisting of all types of documents including prints and photos) over time.

[@redoverdrivetheunstoppable4637]

my first non interrupted tesla coil, that made a blue flame the size of a tennis ball (or little smaller), made a huge amount of ozone, few seconds of operation and you could smell it distinctly, i used to open the door (no problem apparently anyways)... my ebay plasma globe (5 inch diameter) makes it also, but i get near to it on the table

[@johnrehwinkel7241]

I rented a hotel room once, and found one of these inside. Naturally, I took it to bits, had a nice look around, and put it back together before I called building maintenance to come retrieve it. That particular one had electrodes punched out of sheet metal into a forest of points on each side, with the usual ceramic plate between them. I powered it up briefly, and it produced a prodigious amount of ozone.

[@astrangeone]

It's a great tool for hotels. And apparently kills bedbugs dead.

[@vaporainwaves]

I remember as a kid I had all sorts of allergies, and we had a Quartz lamp, with a timer and when we would come back home, there would be this distinctive smell from the lamp. Mmmm memories.

[@bigclivedotcom]

The modern version of that will be coming up in a video soon. Readily available on eBay for about £10.

[@nosch43]

we have huge ones for deoderizing 3 bedroom apartment in an hour we use at the resort I work at, and it's freaking cool

[@Nexfero]

Honestly I prefer using quartz UV-C florescent lights to generate Ozone and the ultraviolet also has a sterilizing effect as well.

[@bigclivedotcom]

Video on my new 20W UVC compact fluorescent lamp coming soon.

[@itsevilbert]

Which sterilizes by shredding DNA, which is a scary concept.

[@yesihavereadit]

Nexfero how does uv c generate ozone?

[@Nexfero]

+turnerchris1 ionizing radiation does just that , it creates ions when it interacts with air. Ultraviolet is a form of ionizing radiation so when the UV-C lights strikes O2 molecules it breaks them up, those free oxygen atoms, ions, then recombine with existing O2 atoms thus creating O3 also called ozone.

[@yesihavereadit]

Nexfero I never knew that, it's not as efficient apparently,but it does work

[@karoma7898]

I used a 20W UV-C lamp to kill mould that was stinking my room after some water damage, 2 hours, and i opened the windows for the rest of the day... Damn that ozone stuck to everything! Clothes bed, and weirdly, the inside of my school backpack. I didn't realize it penetrates everything.

[@steviebboy69]

I was going to get something like this years ago for air cleaning and the like. Oh is it just me or does the symbol on the fan remind you of the old British Leyland symbol

[@zackstewart4109]

Excellent! I've been wondering about those. Nice sound on this one, as well!

[@pauljs75]

Different than the home use "air cleaner" or "ionizer" devices I've seen. Those usually just have big flat plates (stainless?) and wires offset from them, or it's a big sheet of metal with holes cut out and then needles on the opposing side. Then again their claimed primary purpose is to capture dust or whatever, yet it seems when in operation they still seem to create a whole lot of ozone.

[@bigclivedotcom]

Those tend to use high voltage to cause air movement and do create a lot of ozone in use.

[@MalleusSemperVictor]

I love the smell of O3 in the morning. Smells like... sanitation.

[@steveroberts1861]

I remember staying in a hotel where they had a large unit running in the hallway. The smell was very sickly.

[@JohnSmith-bb2np]

What I've always heard is that, if Ozone is down here it's a respiratory hazard and pollutant, but if it's up there in the upper atmosphere, it's safe and beneficial UV absorbent. When indoor Ozone generators became popular, it was discovered they cause harmful pollution, and no one bought them anymore. I see them all the time at Thrift Stores.

[@NinoJoel]

Ozone falls apart after some hours on its own so what pollution are we talking about

[@raymondmucklow3793]

If everyone of these on the planet was turned on at the same time, would that fix the big hole in the Ozone. Another fine video Sir. For the trolls I was of course kidding

[@johnrehwinkel7241]

Interestingly, that hole in the ozone layer is much improved these days, but you don't hear much about it, because apparently bad news travels better.

[@ALAPINO]

Actually, quite recently, the body in charge of monitoring the ozone 'hole' has found that someone (*cough* China *cough*) has been dumping MASSIVE amounts CFCs back into the atmosphere. Surprisingly, it's been kept pretty quiet as side from a few science outlets on KZbin and science news websites. Sadly, it won't be long until the 'healing' of the Ozone layer since CFCs were banned will have been undone.

[@ALAPINO]

I'd like to point out that the people responsible for the monitoring of the Ozone layer would not 100% say, however by evidence of the timing, direction of winds, and such they determined the origin of release was East Asia... *cough*

[@Davis38]

No, it would fix the Big Clive Hole

[@zh84]

When I was in SYS Physics in my last year at school the teacher did some demonstrations of sparks and corona dishcharge with a van de Graaf generator, and I took some extraordinary long-exposure photographs of it. The silver dome lit by an eerie purple glow looked like a flying saucer coming in to land. Doesn't the discharge also generate nitrogen oxides? They are certainly generated by nature's high-voltage sparks, i.e. lightning.

[@bigclivedotcom]

It generates all manner of oxides. The ozone generators who claim theirs don't are usually either lying or have flawed tests where the test indicator is bleached out by the ozone.

[@biggav5555]

We use one at work that uses pure oxygen for generation. So only oxygen and ozone emitted. They are dangerous machines and you shouldn't be breathing it in.

[@WineScrounger]

Gavin Turner a slow leak of pure, highly reactive oxygen. Nope. I’m out.

I imagine you could apply the same idea to chlorine gas to make it even more reactive, wouldn't be surprised if they even use fluorine in this manner for industrial purposes.

[@juncusbufonius]

I was involved in some research into levels of pollutants in my county and being rural ozone was considered a problem as we do not have enough nitrogen dioxide from cars to cancel it out in low lying areas. In those areas crop and people damage can occur where low level ozone pools. Well that what the science said.

[@Meteora125]

I remeber the old video about this, but I appreciate this new version anyway!

[@ThatGoth]

[@Io1564]

Hey Clive, just discovered your channel. Interesting af! I am in SE Europe and due to the climate my digs suffer from mold problems. I wonder if you know if ozone is sporicidal? I know it kills the smell but does it nuke the spores also? Do you have any experience with Ozone being used to kill mold? Cheers!

[@NinoJoel]

May be way late but ozone kills anything living / organic so mold and spores / bacteria etc is also destroyed

[@Aecidius]

I enjoyed how the ozone layer built up the longer you were recording it, fascinating. Seems like something you could build yourself, who doesn't love playing with very large currents?

[@heyarno]

You mean high voltages, the current should actually be very low in this application, as no spark is generated to complete the circuit.

[@phils4634]

All the parts are available via EBay, etc. The best HV sources are either oil burner ignition transformer modules, or Neon sign transformers. The latter are more effective (and seem to last longer), but are also more costly.

[@userPrehistoricman]

The increase in intensity was most likely the exposure of the camera. No real reason it should ramp up

[@drteeth7054]

Another fantastic video from BC productions!

[@Alan_Stinchcombe]

I've seen fresh lab rubber tubing attached to the output of a lab ozone generator go gooey and drop off within a few minutes. That's why I don't want ozone in my nose or lungs. :)

[@bigclivedotcom]

Rubber is very susceptible to ozone damage, especially at the concentrations a lab generator can supply when fed with pure oxygen.

[@Alan_Stinchcombe]

As I recall, that generator was only fed with air. I'm not volunteering to compare the susceptibility of my respiratory tract with that of a piece of rubber tubing. According to NIOSH, ozone levels of 5 ppm or higher are considered immediately dangerous to life or health.

[@bigclivedotcom]

If you can smell ozone there's too much. Typically around 0.1ppm or less.

[@Alan_Stinchcombe]

Yes, like hydrogen sulphide. 0.1ppm is NIOSH's recommended limit for occupational exposure.

[@Alan_Stinchcombe]

US EPA can't find any evidence that ozone room deodorisers work, other than by ozone's pungency masking other odours.

[@J.F.K.O]

nice video i have just bought one to use in my cars, and was wondering how they works. It's going to be nice to see if it can remove the smell of old wunderbaums diesel smoke and cigarettes :P

[@scottgray6276]

Corona Discharge would make a pretty good drag name...

[@pixelpatter01]

The electric field of the secondaries high voltage creates a gradient that pulls apart a normal oxygen molecule by being stronger than the attraction between the oxygen atoms. Keeping the electrode very close together help increase the gradient and allows a lower voltage. The O2 molecule gets pulled by the field and breaks, but the field isn't strong enough to break down the dielectric strength of the insulator between them. Alumina or aluminum oxide plates are used in mine. en.wikipedia.org/wiki/Bond-dissociation_energy Ozone is a poison gas, which has an IDLH (immediate danger to life and health) of 5 ppm and is ten times more poisonous than hydrogen Cyanide (HCN) which has a IDLH of 50ppm (parts per million). I agree it smells pleasant and it does a wonderful job of deodorizing, but don't breath it.

[@midnightfoxxx8231]

Ozone smells awesome

[@KatherineClairmont]

wouldn't a device like this create nitrogen oxides as well as ozone?

[@bigclivedotcom]

It will oxidise everything it can.

[@gordonlawrence4749]

I was wondering that too - IE Nitrous oxide etc. Not certain though as that is a brown/dark orange gas.

[@WaltonPete]

Gordon Lawrence Only in concentration. If it's mixed with air and other ionised gases you probably wouldn't see it.

[@mikeguitar9769]

Not nitrous oxide (N2O), but rather nitrogen dioxide NO2, and nitric oxide NO.

[@Chuckiele]

there could be trace amounts of nitrous aswell as it indeed oxidises everything :D

[@brianrogers7543]

Great video very thoroughly explained. I’ve been researching different ozone generators and with some it has been mentioned that for a unit to be effective it has to create enough ozone to eliminate mildew spores and different bacteria it requires what is referred to as a “punch like shock” of actual ozone. Would you agree with that? and if yes, what specific type of unit would you recommend? Thanks for your help. Brian

[@bigclivedotcom]

Hi Brian. For mold spores it would have to be quite strong. Take a look at my video about the UVC lamp. It has a double effect of ozone and UVC, but poses a skin and eye hazard if in the same room. It's important to trace any source of damp to get rid of mold completely.

Thank you sir. I don’t have mold caused by water damage and there isn’t any visible signs on walls or concrete floor. Its powdery mildew on my plants leaves that I’m trying to eliminate. I’ve sprayed the whole room with hydrogen peroxide. But I’m still experiencing powdery mildew spores on the plants leaves and thought I’d try an ozone generator. Do you think the video you have suggested would cure the problem?

[@fins59]

Do carbon brushed electric motors generate ozone by the small amount of sparking? If so I have a washing machine, fridge, air conditioner, vacuum cleaners, heater, fan, printer, desktop computer, laptop, power tools, shaver, toothbrush, all generating ozone inside. Signed Worried of Lindisfarne.

[@bigclivedotcom]

The amount of ozone produced by motors is tiny. Nothing to worry about.

[@fins59]

Thank you for your replies gentlemen. Signed Not so worried anymore of Lindisfarne.

Cheers to you and your brother for entertaining and informative videos!

[@nw8000]

Is this a good one to buy then?

[@retromodernart4426]

Hi Mr. Big Clive, would you kindly tell me what kind of camera you used to make the video? Thank you very much.

[@bigclivedotcom]

Moto G4 phone.

[@AWIERD1]

They use those ozone generators in apartments when a smoker moves out so they can sell it.

[@JimFortune]

I love the smell of ozone in the morning. It's the smell of Lionel!

[@stupiderthanjupiter4987]

AC locos only ;)

[@restorer19]

Does carbon fiber, like the thin filaments used in modern ionizer emitters, react with ozone? I suspect not, but it'd be terrible if it combined to carbon monoxide or something like that. It seems that a mesh made of fine strands of carbon fiber would make a good corona.

[@bigclivedotcom]

I don't think carbon fibre is suited to ozone generation. But it seems good as an emitter in ionisers.

[@salmonline]

I'd REALLY love to view a video of you "Clive-ing" a valve amplifier.

[@no1slisteninganyway]

So is this setup more or less efficient than replacing the coil and power supply with a UV-C bulb?

[@Dev-lc4cd]

Could you do a video where you investigate a hydroxyl generator, and how it works differently than an ozone generator?

[@bigclivedotcom]

See my japanese air purifier videos.

[@Dev-lc4cd]

Just watched them, and its only added to my intrigue in this niche type of product. Where I live, New Jersey, US, insurance companies require the use of, specifically, hydroxyl generators, after a fire incident in a dwelling, to remove the smoke odors in occupied space (unlike ozone generator which aren't acceptable, and definitely not in occupied spaces). Which gives me an impression of legitimacy of the usefulness of these generators, but further research just leaves me with more questions, uncertainty, and intrigue. I want these things to actually be what they say they are on paper. It would be quite a game changer for me if they were. These units look like large box fans with UV lamps inside. The only explanation I've been able to find on how they work is that the UV lamps are paired with these titanium dioxide doped filters that acts as a photocatalysis, generating hydroxyl radicals, with minimal ozone production. I've previously read research about the use of TiO2 as a photocatalytic oxidizer in the production of a new type of coating for windows that makes the windows "self-cleaning". Wait, goddamn it. I'm sorry, I'm creating another wall of text geeking out about some tech. If any of this interest you, I can go on and shoot you an email. Thanks for responding.🙏🙏

[@darkdelta]

Another winner! Very interesting.

[@Strider9655]

I've got one of these (similar), although fitted with the ozone generator you looked at more recently, it came with a euro plug and ground/earth, so I had to gut it, fit 3 core flex, UK plug and earth the outer case, really not suitable for the UK without doing this, but I guess that's why there was no UK plug option :p What gets me though, and this one is the same, the fan is pulling air in, instead of pushing air out, so you end up with this pocket of positive pressure ozone inside the unit, whilst not dispersing the ozone particularly well, and we already know that high concentrations of ozone can damage rubber and plastics. I've looked around the internet, they're all the same, It must be deliberate and I can't work out why they do it.........

[@bigclivedotcom]

The fan pulls air into the unit so it isn't pulling high levels of freshly generated ozone past itself.

[@richardnanis]

Is the ozone procuction depending on the polarity? So is it the positive electode where the corona discharge takes place or the negative one? Or could you just use (high frequent) AC as well? thanks :-)

[@bigclivedotcom]

These use high frequency AC.

[@misfitthemad276]

+Bigclivedotcom Clive I have the guts of two of those USB plasma balls that lost their vacuum after a month or two. Would I be able to re-purpose those to make a small Ozone generator? Cheers.

[@bigclivedotcom]

They might work for that, although they may overheat with the wrong load (corona discharge plates have a capacitive effect.) They could also be used as single electrode energisers for other applications.

[@misfitthemad276]

Thanks for the reply. I might give it a go if I can find (or make) a suitable corona element thingy. ;)

[@misfitthemad276]

What "other applications" do you have in mind Clive? (I'm trying to decide if mine deserve storage space.) Cheers.

[@pantherplatform]

Sounds like the hole in the ozone layer is gonna get filled with the ozone machine. Makes as much sense as sea levels rising enough to cover the entire planet. Where is all that water going to come from?

Hi, I have an ozone tube but not power supply. Would you mind giving more information on what the suppy does? Does it convert ac to ac for high votage or ac to dc? and two cables that are connected to tube are both phases or positive charged?

[@restcure]

Yeah. after a while, that ozone smell does tend to get up one's nose ...

[@ggesdsdsdsd]

Will it kill the Coronavirus though?

[@millomweb]

2:26 Not many screwdrivers come with an on/off button. Is that for a light ?

[@jafafa]

I wonder if one of these would be good for "antiquing" things. It's easy enough with coppers, etc. with chemicals (though detectable) but with wood and other things it's harder to fake in a way that can pass close inspection. I wonder if the free oxygen and ozone atoms would accelerate the process.

[@nofider1]

Hi Clive. Is the cap possibly for PF correction being an inductive load ? . missed what amount of current it draws. C. :-}

[@bigclivedotcom]

I doubt it in this instance, since it's a low load and this type of manufacturer doesn't tend to bother with power factor correction.

[@poptartmcjelly7054]

could it be the nitrogen dioxide that sanitizes, because it forms nitric acid when it bonds with water?

[@raymondj8768]

kool video Clive but 1 thing the fan wount really pull any air threw the tube the middle of the fan is solid and wount move any air threw the middle so its all going around the tube thanks buddy for a nother vid have a great day thanks for the knolage

[@bigclivedotcom]

The ozone is being generated on the outside of the tube.

[@raymondj8768]

yea thats why they dident worry about getting air on the inside . i learn so very much from you your one smart cookie dude lol

[@chrisbysize]

Can you check the temperature with a IR-cam? I have a chinese version of this setup and it spits out ~2ppm for about 2min and drops down to 15ppb after 15min on time due to self-heating of the tube- Tube gets about 40-45°C hot, but the surface temperature seems to be enough to degradated O3 rapidly. Also be careful- O3 can cause a bloddy nose and you won't smell O3 after a short time. It works well to get rid of smelly shoes.

[@bigclivedotcom]

For smelly shoes check out my video called - fix your feet It will solve stinky footwear problems without ozone.

[@morosanuandrei4692]

Nice video, can you recommend a trusted vendor of this equipment, please

[@bigclivedotcom]

Alas no. It all tends to be random.

[@d2sfavs]

i like how you explain ozone.i was going to use a UV light on the air intake to my wood stove.will the ozone hurt the fan and the metal in the stove?i see they have UV lights that go into AC units to disinfect the air.

[@anilkumarp7005]

What about rate want to 3g to5g machine portable how much rate available place money etc,

[@rich1051414]

So basically, any material that produces a protective oxide layer is safe to use in an ozone rich environment, or can it even attack some of these as well?

[@bigclivedotcom]

The main materials seem to be aluminium, stainless steel and silicone. Not sure what other materials are suited to use with high ozone concentrations.

[@rollymaster16]

I can see the light and hear the noise as well sounds similar to a crt

[@agvulpine]

I would like to build one of these, though I'm still on the fence about those ceramic panels or building my own glass cylinder.

[@bigclivedotcom]

Ceramic has a much higher electrical strength than glass.

[@sikos_2301]

I feel so clever after this video.
