Water sphere air cleaner.

[@MarkShannonroad_videos]

This is the type of product they sell at state fairs. It's fun to watch all the bowls with swishing water going around a tornado shaped funnel. The sellers make so many misleading statements about it because they know you'll never see them again. They charge $40 to $60 for them. Then you take it home and it sucks at what it does, but you use it anyway because you've pissed away $40 to $60 on it.

James Coyle Don't get one of these, they're next to useless. If you want a good aroma diffuser, have a look for the Ultrasonic Aroma Diffusers. Amazing machines, super effective at dispersing essential oils into the air, plus they will add a little humidity, if that's what you want.

[@Jesus2di4U]

Somewhere within 2008-2011, I had another brand and version of this air revitalizer (old generation before the LED light design came out) that essentially was the same design, and I found what you say now exactly to have been true then: however good the air purifying effect is, the swishing water and aromatherapy aspect created a wonderful feng shui effect and great 'white noise' and scents for sleeping and mood enhancement. ~C

I LOVE seeing products like this re-purposed after hitting the market because they found a more efficient application. This right here started as a aromatic diffuser. My parents had one at their old place where you'd mixed an oil with water and it would spin around like that. We DID stop using it because the water would become murky and just look unappealing. We also had a dog who shed a lot and kept finding hair in the bowl. Now it's came back literally as an "air cleaner", genius! Round 2 fellers.

It's called an air washer. They don't work as well as HEPA air purifiers, but they are good for situations where both humidification and reduction of dust are needed. Bigger models that are less gimmicky exist.

If you’ve never used an air filter these are great. kzbin.infoUgkx_dppjvjF8BYEmPSDTcgCUdRsgWYLXNHN I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!

[@twocvbloke]

I remember doing something like this as a kid with the motor and fan from a small battery powered vacuum cleaner thing with the fan sat over a jar of water, only there was no tube to suck up the water, it just created a vortex like a miniature whirlwind that pulled the water up into the fan and sprayed back down the sides... :D

[@terrytytula]

Great video, and I know this is a technical review. But now I would really like to know if it actually works as a air filter .

[@hyvahyva]

Mechanism is identical to that of the Devilbiss "cool mist" humidifiers sold in Walgreens stores here, which have a little row of pins that it throws the water against to break it into fine droplets and coalesce the larger drops back so they recirculate into the basin instead of getting spit out.

[@voodoopunchie5519]

Homemedics made one of these maybe ten years ago and I got it as a gift and really quite liked it. You have to wash it regularly, obviously, but the fragrance stuff that you put in the water has a nice clean smell without being very overpowering, and it worked great as a sort of cool mist humidifier in winter. Aside from daily washing and refilling it was really pretty low maintenance. I don't know about "cleaning" the air, but it would trap some airborne dust, though I'm sure only a minuscule amount.

[@NeutronicalGaming]

Air is actually amazingly dirty at times, it's really surprising if you set up a filter in a room you think is kind of ok you come back in a week or two and it's incredible the coating of film you get across it just from something like a box fan with microfibre towel across it, it goes grey over time and stains like heck i'm just glad that dosen't end up in my lungs! it convinced me to go for an air cleaner in my bedroom always and i have to say i sleep better letting fresh air in in the mornings and letting my filter run all day i cant comment on this water swirlimijig but i know there's an unbelievable of dirt in the air to be removed if that's your goal in life!

[@KRich408]

Reminds me of a old Vicks Humidifier I think it's borrowed from that tech! They had a spinning part exactly like that but you could put Vick Vapo Rub in a little chamber where vapor came out!

[@oldbutstillcurious3615]

Very interesting, even during boyhood I've appreciated the bronchial relief that Vick's Vapo Rub delivers. Here in the UK I'd never previously heard of any kind of automated vapor spreading device, we have had to rely on adding boiling water to a basin containing a teaspoon full of Vick 'gel'', (as an adult I did get a free promo plastic 'beaker' specifically for that purpose). I'm retired now but always keep a pot of Vick's Vapo Rub in stock.

[@kd6671]

In the 80s these were used as humidifiers, minus the LEDs. I remember them working well but they rotated much faster and would produce a fine, fog like mist. You would need to clean them well and add a bit of bleach to keep it from getting funky. I also had a "steam" humidifier that was insanely dangerous, it worked by submerging electrodes in slightly salty water. The thing is there was no interlock so you could remove the cover/electrode assembly while powered, also there was no kind of current limiting or fuse so you could add enough salt to make a violent, light dimming, breaker tripping show.

[@JerryEricsson]

Back in the 1970's they used to sell humidifiers for the child's room, when they had a cold of flu. They were not clear, but they did seem to ease the children's cough and make it easier for them to breath.

[@gregzeng]

Inland Australia has low humidity air. Humidity machines are good for the nose and skin. Especially in cold weather. Love the idea of brightness and removing the light of the machine.

[@JerryEricsson]

I too had a unit like this when I was a kid. It had the tube as well but, of course the tub was a solid color, green if I remember right. They were sold as humidifier for the "sick room" and mom always had it next to my bed, well after we moved to a house with power, when I was ill with a cold or the flu. It put out quite a mist and was called a cold air humidifier, in contrast to the warm air which was actually steam. I don't know if it worked very well or not, but I think it did bring a bit of relief to my sinuses back then.

[@jmcarp0]

In the US we have humidifiers with that exact same motor/funnel thingy. But it has an outlet where the spray comes out into the room rather than staying mostly in the bowl. No LEDs though :)

[@mattlm64]

I used to own one of these, but they get manky and annoying to clean. It might be a good idea to use de-ionised water with them.

[@pepedrat2982]

I got one of these for the kitchen (and smoking room). I liked the low wattage, and the lack of filter to clog. I hoped it would stop my tobacco tar, and whatever condenses out of cooking vapours from coating the ceiling and walls. Anyway....they certainly do something, but I'm not sure what. I ran it without the additive, and it certainly draws cigarette smoke towards it, as the underside of the lid soon got yellowed, as did the tiled area close to it. Plus the fan and the cone developed some kind of smeggy deposits. These weren't oily, and I'm not sure if they were a bacterial build up in the water. They needed cleaning off every day. When I wiped the bowl, the tissue would be brownish, so it might have caught some tar from my smoking. Any road up, thanks for this video, and...why is it safe to mix lecky and water in this device? Cheers.

[@bowlsallbroken]

Good googlymoogly imagine what your lungs look like!

[@HattmannenNilsson]

I suppose that if there's a lot of dust floating around in the air, some of it will get trapped in the water, but I don't see how it would clean the air in any other way.

[@tyrgoossens]

It does make some intuitive sense. People with allergies will often feel a bit better when it rains because water will knock dust and pollen out of the air.

[@HattmannenNilsson]

I imagine it would bind some pollen and other dust from the air in the room that happens to pass though the unit, but not enough to make much of a difference. Sure if you scaled it up to, lets say, the size of an ordinary AC unit, put one in every room and closed the ventilation, it might make a perceptible difference, but I doubt the efficacy. It makes for a very nice decoration, though.

[@HELLHAMMERHANDHIX]

a tapered shaft going to the bottom is always interesting !!!

[@TheNuclearPinball]

I wonder if they make scaled up versions of these for dust on work zones. I have a feeling that it would be very effective for wood dust, plaster etc and it might be easier to clean than a air filter.

These things were around in the 80s with out LEDs as humidifiers. I remember them being in drug stores or the medical isle of grocery stores. They went out of favor after black mold became a big news topic and it was found that these machines grew mold after a while. I am kind of curious to know if they solved the mold problem? It doesn't look like those LEDs are UV or anything so I am not sure they did solve it.

[@harshbarj]

Essentially this is a humidifier. In the 70's and 80's (perhaps earlier and later) in the states, the Vicks corporation sold large square humidifiers that used this same setup and included a area to place some of their 'vaporub' above the motor to heat it. It always left the floor near it wet, but it did work as a humidifier.

[@FireFoxBancroft]

Pretty much a cool mist humidifier. Without the skirt comb around the impeller the water doesn't get broken up as much. You should look at impeller-based humidifiers they're about the same except have an arrangement of teeth (the comb) around the impeller spinner/fan.

This might be the answer to my problem. I would like to have a "low level" of air freshener (scent) in the air here in my home, UN-like what happens when those plug-in type air fresheners are used.

Even with the things plugged in far off in another part of the house. This unit might be worth a try. As long as they don't spray water everywhere LOL or short out.

Rexair still makes Rainbow systems and the Rainmate. Still the best water based vacuums out there.

[@richardwernst]

I think I'm missing something. I thought the air was pushed through the mist/droplets/whatever. But it's above at least most of the droplets (from under fan/flat disk part). If the air was forced through the mist, I could see it being a lot better at dust collection. When I was very young, (1950s), my mom had a vacuum (cast iron!) that you put water in the bottom and the air was forced around a sharp bend and the dust/dirt couldn't make the turn so go caught by the water at the bottom. Worked excellently, but I'm sure it was a bear to move around with it being cast iron (really!) and filled with a quart or two(?) of water. (an no wheels that I recall).

[@deltalambda3864]

"does this actually work?" At getting people's money? Absolutely! Does it do anything useful? Based on the size of the air vents, I'd have to say "no". You've probably got more air entering the room from either natural or forced ventilation than that device can process. So, it's always going to be "behind". It might be useful as a humidifier, but that's about it.

[@chrisrichard298]

I used to work in a commercial laundry that had a much larger version of this to remove lint from the dryer exhaust. Essentially it was a big stainless steel box with water jets that sprayed a fine mist of water into the air stream and some baffles to keep the water mostly contained in the box. The bottom of the box was shaped like a giant funnel and had a nylon bag on the end. The nylon bag sat in a tank that had a pump that pumped the water back to the box. At the end of the day, the nylon bag would be full of 30-40 pounds of wet lint. The concept is the same, so to all the naysayers, yes it works, though I'm not sure how effective this would be given its tiny size. Also, those wet lint collection systems were phased out due to concerns about mold and legionnaire's. We used to change the water in it every day and someone (usually me) would have to go inside it every couple of weeks and wash it out because the wet lint would collect all inside of it, too. I was so happy to see that thing finally go away.

[@csatterley]

The principle of using water sprays to clean gas/air is pretty sound and the basis of many industrial processes. However as others have said I'd be worried about the hygiene of this unless you changed the water and fully cleaned the unit very regularly.

[@stcrussman]

How do the color changing LEDs work? If they are all the same type I would think they would sync because of being powered on at the same time.

[@PaulPaulsen]

in the little led-package, there are 3 leds and a little microcontroller (bare dies only). at first, they will start in sync. but they drift off over time, because they´re not synced to one another.

[@BluntForceTrauma666]

Many, _many_ moons ago, when I was a kid and if I had a cough or a cold or something, my mom would put a humidifier in my room that worked very similarly to this, just larger. That thing would shoot out a two-foot spray of fine droplets and air and I specifically remember the long cone shaped "tube" that went down into the water and a top disc that I would now label an impeller. Stuff like that always fascinated me...I could never understand (at the time) what in the world made it "suck" the water up and out like that...

[@bigclivedotcom]

It might have been an ultrasonic dehumidifier. They produce a plume of cold steam.

[@BluntForceTrauma666]

Nope, it had a shaded pole motor driving a rotating part just like the one shown in this air cleaner disassembly. I know for sure it wasn't an ultrasonic, I would have gone NUTS playing around with and trying to understand one of those! We're talking mid-70's-ish and I don't recall ultrasonics being widely available at that time. But yeah, it had a long cone shaped tube with a small opening at the end that was immersed in the "tank" and at the top (if I recall correctly) was a disc that resembled the centrifugal impeller you would find in a vacuum cleaner. The disc acted as a "fan" which sucked in air through the top, mixed it with the water and swirled it around in the lower reservoir making kind of a mist "tornado". A little sliding door on the side would allow some of that mist to escape. Obviously WAY before safety switches were common, this thing didn't care if the top was on or not - it would still spin. I don't even think the damn thing had a power switch - you just plugged it in and away it went! Haha, I can remember making HUGE messes when I would try to lift the top off juuuuuust enough to peek inside and it would always sling water EVERYWHERE. Heh, it's a good thing my mom recognized my budding curiosity and where it would eventually lead, otherwise I probably would have gotten my ass tanned for all the mild water damage! Hahha...

I've always remembered how to wire a discrete bridge rectifier by holding two of the diodes together anode to anode at a right angle as a bridge is commonly drawn in one hand. Then hold the other two cathode to cathode in the other. Then bring the remaining diode ends together with both hands and you have a bridge rectifier. The ends you're holding (anode to anode and cathode to cathode) are the DC output the other ends you're not holding are the AC input.

[@leebromley1411]

Wonder if it works on the very basic principal of the Rainbow Vacuum cleaners to trap dirt and dust in the water?

[@phinok.m.628]

Huh... The new color changing LEDs can be wired in series? How does that work? Considering that the channels are internally faded back and forth by a tiny micro controller I would expect them to draw a rather variable current. Did they sync up the fading of the individual channels so that the LED consumes a constant current? Does the micro controller shunt LEDs when not turned on, rather then controlling the output of the LED? That would be a reasonable solution I guess.

[@cantankerousclankingcontra8295]

H2O does have a partial electric charged as can be demonstrated by charging a glass rod with static electricity and placing it near a small stream of water from a tap. It is possible that this partial charge may have some effect on dust particles and may be the reason for the false claim that is has an ionisation effect.

[@greenaum]

No, the glass rod induces a charge in the water. Basic static electricity GCSE stuff.

@4:20 I like it when people print out a copy of a web page rather than just screenshoting it . xD

[@chrisengland5523]

Hmm, so we've got a mains fan and live connections to LED's a few centimetres above a bowl of soapy, dirty (i.e. highly conductive) water that is being splashed about by the airflow from the fan. Ideal for placing in a kid's bedroom, where there's no chance of it getting knocked over. What could possibly go wrong?

[@drteeth7054]

Can BC ever resist the temptation to dismantle something? Discuss.

[@audiocrush]

how can it clean air when it blows past the water and not through the mist?

[@MazeFrame]

The front intake fans of my computer move about 150m^3 air per hour. How many of those air cleaners would I need to take care of incomming dust?

[@hugorafaelchavezfrias4548]

can make the test that the air that pc sucks go though this air purifier, then check if is dust in the pc :v

[@maicod]

can this device be dangerous concerning legionairs disease ?

[@bigclivedotcom]

Only if it was never cleaned.

[@maicod]

alright

[@SiskinOnUTube]

I got a similar one a few years ago to try to get rid of stinky smoke from my filthy habit. The water did get quite manky. I stopped using it, because I thought it was likely to become a breeding ground for all sorts of air-born germs. An actual ioniser would maybe be a good addition. I wonder why they use a shaded pole motor?

[@c1neal]

Does it actually filter air?

[@Cashpots]

New pound coin, Clive, I understand one of the "special security features" on the new pound coin is that the queen's face fluoresces at a certain frequency of blue light only. Now who would be the ideal person to find out the frequency with your supply of LEDs? Well, you, naturally! :-)

[@bigclivedotcom]

I'm very sceptical about that, especially when they put out statements like "The binary code - and the exact light frequency needed to check it exists - remain a closely guarded secret known only by the Government. " I've just checked with a laser and saw nothing fluorescing. Any pigment they used would have to be embedded in the metal and handle being cast in molten metal while maintaining its position. I'll remain sceptical until someone demonstrates it convincingly online.

[@joannewhilde7359]

Rather scary to think there@s bugger all waterproof or conformal coating of the pcb to stop electrocution happening. Is it IP rated?

[@anilpatra9221]

What is the cost?

[@MoritzvonSchweinitz]

Does anyone know if Clive has a video explaining that particular type of fan motor? I just disassembled one yesterday, and would like to know how it works, exactly.

[@bigclivedotcom]

It's called a shaded pole motor. The copper shunt rings cause a slight phase shift which gives it directional rotation.

[@MoritzvonSchweinitz]

bigclivedotcom Thank you for that pointer, which finally allowed me to understand them. Ingenious solution! Also thank you for all your videos! :-)

[@piratapan]

Big Clive! Where can I buy your favourite bits-tool that you always use?

[@bigclivedotcom]

In the UK you can buy it from Poundland. Elsewhere you can buy it from eBay as a 9 in 1 or 8 in 1 precision screwdriver.

[@piratapan]

Thanks, I found it!

[@brickley2000]

So the dust is gone, but what about the mold ?

[@28YorkshireRose12]

A waterwall is more effective, nicer to look at, nicer to listen to, and you get them in posh hotels and big office block foyers. . . . . And I'm sure I've seen some smaller, domestic, sized versions. Otherwise, just use a spin dryer!

[@FireSwordl]

I bought exactly the same unit few years ago. It really sucks the dirt, and becomes hard to clean. I prefer to use it with water only. The LEDs stopped working a few months after I bought it. I have to fix them.

[@FireSwordl]

The water becomes greasy, also the inner side of the bowl. It is easy to clean, just DON'T put it in the dishwasher! But there is a lot of dirt on the propeler, the vent, inside of the propeler funnel, every plastic part that is on the air's way. You can try with a wet tissue, but it is hard to follow every curve.

[@Frantzcesa]

Ionizing effect comes from the the water. When water crashes against something it creates negative ion. That why the fan throws the water on the side.

[@JG-nx3jg]

To purify the liquid and prevent the spread of airborne bacteria could the lights not be UV

[@JayH7745]

Amazon and ebay both sell units that look similar to this one you have. Some even list "Ozone Generator" in the features. "Like you mentioned" where yours has an area where something more could be mounted. I'd really like to see how they build one in, if they do. I want to buy one of these but it's going to be hard picking out which one has all the Ozone BELLS and Generator WHISTLES. :)

[@FredBedderhead]

why not wrap wire around the motor winding to pickup some power to driver some LEDs

[@FredBedderhead]

it common to use a coil of wire to pickup some power, I seen it used all the time in microwave ovens transformer and TV's flyback to get a volt or two
