Years ago when I first moved to Japan I had to use the bucket it did a great job until I got. A spray booth in Japan Apartments you don't have very much room and you have to be very creative .I made Many different variations of it..but nothing will replace a good vent to the outside. Good video Robert Keep them coming brother

[@randomnickify]

Precisely because of that many Hobby shops in Japan has a "hobby room" with multiple spray booths with compressors and airbrushes set up that you can rent for hours. Some even have key lockers where you can left your model while it dries instead of hauling it back and forth. I saw a Japanese model youtuber visiting few of those, check your area.

[@jugoretz]

Great alternatives for folks without an easily accessible window! One thing to remember if you use solvent-based paints is to replace your carbon frequently! Activated carbon gets “used up” (all adsorption sites in the molecular structure filled up) pretty fast, and then it’s useless. You might not smell or notice any difference, but the VOCs will not be filtered anymore and it’s not great to be breathing those in an enclosed space. Even if it smells fine. Put in fresh carbon every so often (how often depends on how much you airbrush), and this will work great.

[@john9801]

Also it starts degrading as soon as you open it. It constantly absorbs stuff from the air. Doesn't have to be from your paints.

[@ninjatango]

This is often overlooked. For a respirator to maintain its rating, it has to be in a sealed container when not in use. They degrade rapidly in open atmosphere due to absorbing everything from the air. You need to keep your mask (or just its filters) in a sealed Tupperware or plastic bag, etc.. Throwing the mask in a gallon Ziplock bag after use extends its useful life enormously.

[@habiks]

Great alternative? It's like saying you can also put a plastic bag over your head if you don't have a window. This thing does exactly nothing. Every spray booth already catches overspray in a cloth - but all the solvent vapors gets past it like nothing. Adding some random water vapor trap at the end doesn't do anything.

[@HobbyBench]

​@habiks all these are completely ineffective and a waste of money. The only way I've found to effectively filter VOCs is using a canlite 20 pound exhaust filter, after using the kaizo water curtain. I've voc tested this and it does work, but will need to be changed or redried every 1-2 years depending on your usage. I've VOC tested doing into a water bucket and it does nothing but move vocs

[@windforward9810]

@@ninjatangothat is where people are making a huge mistake that is the reason I hate that everyone thinks wear a filter is the greatest thing in the world. Especially for resin 3d printing in the house, yes the use a filter when they open the lid up but generally it will spread the voc all over the inside the house, go through the walls to up stairs. Than they don’t change the carbon mask or the air filters they have on the portable units. 7 to 10 day normally is what they are good for place them in the plastic bag will extend them how long it depends on use I would replace them at the 14 day mark or if you use them every day max 10 days.

I'd like to say thank you for getting me back into model building again. Your videos are the best. After watching a few of your videos I decided to pull out a model that I started 30 to 35 years ago. AMT pro shop 57 chevy bel air. Hope I don't bore you but here's a little history about me. When I was around 10 yrs old I began building models { 50's... 60's and some 70's cars and trucks }. Then a got a mini bike and models went away. In my early 20's I started again for a few years but then women got in the way and I stopped. In my early 30's I picked it up again and went crazy. I had about 150 unbuilt models and lots of nice accessories and hand tools. That lasted for around 5 yrs but life got in the way and I stopped. When I moved to florida from R.I. I took them with me { gave away half of them}. They sat in my garage until one day last year I decided to bring in the 57 and start working on it again but it just sat in my room for one year. Two weeks ago I happened to see one of your videos on youtube and got the fever again { Thanks to you }. I went to lobby hobby { only hobby shop in my area } an family dollar and dollar general and set up my work area { which look great' Thanks to you }. So I just wanted to drop a line and say Thank you. Your vids are the best and I'm looking forward to many more. By the way I'm a 66 year old man felling like a kid again.

[@stowlo]

I love you man but so worried about VOCs removing the smell isn’t necessarily a sign of removing them. 3d printer guys can attest to that with the carbon filters used there. Almost like taking the stink out of propane. Would want a VOC test.

[@NeoPest]

yep this hill robert has decided to climb up on may literally be his dying one

[@Jedi_Jeff]

The carbon filter he listed is designed for VOCs. You will need to replace them at least once a month, depending on usage.

[@NeoPest]

being designed for vocs and being rated for full adsorption of a given fluid's voc contaminants at a specific flow rate are not even in the same universe. there is a very good reason 3m does not use this pad in the respirators sold for vocs. there is a very good reason all commercial voc scrubbers use a properly settled and packed bed of activated charcoal pellets or a manufactured carbon matrix block. dwell time and contact time are not matched for adsorbing vocs from an airstream in such a loosely woven matrix with such little carbon by weight @@Jedi_Jeff

[@NeoPest]

there is a huge difference between "designed for vocs" and rated for removal of specific concentration of vocs at a specific flow rate and i assure you these are not rated for the concentration of a paint booth with lacquers sprayed in it. voc removal from air at the speeds a paint booth exhausts its effluent requires something with more actual carbon and much greater contact time with pelletized carbon. it is impossible for the vocs to be adsorbed efficiently enough to produce clean air in the set ups robert shows. for this pad to be effective you would need a serpentine maze chamber with pads in each level and only after passing through several chambers would the effluent be clean of vocs. given that restricting the airflow is not good you would need to account for pressure drops due to each bend in the serpentine array. the cross section of the chaber in each layer would need to be larger than output of the booth to allow for this. we are talking about a custom made fridge sized box with hundreds of dollars of carbon pad to get proper contact time as this pad is so porous and most of the air is unfiltered when exiting each layer id love to see you post any credible source for the claim that replacing the wrong tool for the job once a month makes it the right tool for the job@@Jedi_Jeff

@@NeoPest really appreciate you spending the time to spell it out. We only get one chance at life and I love my lacquer paints but only with a direct vent booth and respirator!

This won't work, if you want a system that's actually safe for spraying inside take a look at my most recent video

[@kilodelta1495]

@@HobbyBench A safe system for spraying inside vents to the outside.

[@HobbyBench]

@kilodelta1495 agreed, that would be the safest with proper ventilation at your unit which most units don't have in the first place. I've actually done VOC testing to verify different setups with a $1000+ testing rig, and the kaizo x plus a 20 pound canlite is the only way that I have found that can reduce working VOCs down to levels that would be considered safe by your typical regs. Doing any of the stuff in the video is completely ineffective, including the water bucket nonsense which I've also VOC tested and it failed even with the kaizo x.

[@mattpace1026]

@@HobbyBench You said on another comment that you tested it with the kaizo and said that was the only way it worked for you. Now you say it doesn't work at all? Come on, man, if you're gonna be completely full of it, at least try to keep your story straight.

[@HobbyBench]

@mattpace1026 I don't think you know how to read. I was pretty clear that using a good intake system like the kaizo x as well as venting it into a canlite with 15-20 pounds of virgin carbon does work. Nothing is as good as venting outside, because your removing the air, but even that only works with a great negative pressure system on the intake and there is only one unit I know of in the consumer market that does that, the kazio x (not the mobile fort)

Thanks for the video. One question. Will these indoor ventilation options trap volatile organic compounds in the carbon filters and not just the smell?

[@ninjatango]

Nope, not at all. It just (somewhat) lessens your ability to detect an odor, which is irrelevant. It’s like saying radioactive materials are safe because you can’t smell them. There is a reason we add a scent to household gas supply so you notice its presence. VOCs from paint are not detectable via odor.

[@NeoPest]

some voc's are very odorous. the strange fruity ester smells of banana or pineapple is one of the biggest smells in hobby paints due to frequent inclusion of butyl acetate. but everything else you said is correct and needs to be seriously considered by robert. he replies to people asking when he will restock something he makes a cut on and other fluffy feel good comments or about his band shirt seen in the video but has completely ignored or even hidden any concerns about it while making more videos showing more ways to blast your home with vocs (it appears he's hidden at least two of my comments on the issue of vocs as they do not show up. i know yt removes comments but i used no banned keywords) @@ninjatango robert, i have always respected you and clicked every video as soon as it showed up and liked them and told people about you. please address this serious elephant in the booth that is proper application of carbon in a voc adsorption stage for recirculating systems that do not vent outside @barbatosrex9473

[@Smedleydog1]

After watching one of your previous videos, I built the bucket system using my 3d printer to print the upper inlet to the bucket that attaches to the paint booth hose and the lower inlet tube that goes down about 200mm or so into the bucket. Then I put 8 holes (30mm dia) in the lid around the inlet. I printed a grate that stands up on posts about 250mm above the bottom of the bucket. It has a hole that the inlet tube goes through. I put the blue filter material on the grate and the black carbon material on top of that. When I close the lid the filter material is right under the lid. I put about 2 or 3 inches of water in the bottom and Bob's your uncle. It keeps me spraying in the winter. Thanks for all of the great tips and information.

A canister inside the bucket, with screens epoxied in place to keep the charcoal pieces out of the canister. I run the hose, from the spray booth, into the bucket trapping the fumes in the charcoal. It works great. No smell.

I'm working on a modification of the bucket hack. I found a lid that is primarily flat all the way across (Ace Hardware bucket). I have six 2" holes around the perimeter of the lid that I cover from the bottom with crescent shaped carbon filters they sell on Amazon for kitty litter boxes. Hot glued a pair of those over the 2" holes on the bottom of the lid. Used hot glue since I should be able to scrape it off the lid when I need to change the filter material. Works like a champ so far.

[@ninjatango]

Sure it works for a few uses, more or less. Of course, you’re not removing the VOCs from your air much.

[@NeoPest]

that carbon pad does not remove the voc's sufficiently to produce clean and safely breathable air but if you do want some form of post filter on the bucket you should know this little trick for hot glue : isopropanol (rubbing alcohol) nearly instantly destroys its grip on an object with as little as 1 drop applied to one edge of the glue requiring no scraping and allowing full removal of the glue from hard surfaces like that plastic lid. add the drop on te edge and then use a toothpick, plastic scraper, fingernail etc to push against the glue edge and as soon as the alcohol wicks itself under the gap you make in the edge its over for the bond

[@broccairns5457]

The last two options are perfect for our condo while being storable. Thank you for introducing me to the world of indoor dryer vents!

[@pixelpuppy]

are these alternatives actually chemically safe solutions? Sure it will catch paint particulates, but what about the toxic VOC fumes? I'd only try this if it filters as good as a gas filtering respirator mask.

[@ninjatango]

No, they are not. It will cut down on dust and particles to some degree but does nothing to address the danger of VOCs. If you are only using water based solvents exclusively, it would be ok but does nothing to prevent toxins from pumping right back into your lungs. They do not absorb into the water, and the buckets and passive filter pads etc. are nowhere near capable of filtering out VOCs. On top of this, the consumer grade filter pads in the video are meant for aquaria and are much less effective in air than in submersion.

[@NeoPest]

no they are not remotely safe for solvents in a closed environment in which you share the atmosphere

[@stevenpuderbaugh821]

So, I have to ask, how do these filtration systems work with venting the harmful vapors from Lacquer or Enamel paints.

Remember when the big scare to make your own masks for covid? I did a little research and found a great material to add for filtering my spray booth and my shop vac. The material used in many reuseable grocery bags (blue Wal Mart bag) is perfect. It will not let water pass through it, but air will pass just fine. I take one of the bags and wrap it around my shop vacuum filter, and the finer particles, that used to plug up my shop vac filter, get stopped on the fabric, and my shop vac filter stays a lot cleaner. So, I applied this theory to my spray booth, and surprisingly enough placing it on the filter minimized the smells even more than with just the charcoal filter.

Smells are not the problem.

[@sgtatarms4780]

We all have concerns about safety and that is a great thing. The best thing for painting in non-ventilated areas is to not do it, however there are ways to mitigate a safer environment to do so, as presented in the video. I guess maybe the part the material I mentioned of catching dust, debris, and yes other fine particulates was not articulated well, for that I apologize. Smells are a good indication to me that there are some particulates floating around that I do not want around. I am no rocket scientist nor am I saying it will remove 100% of anything. I am just adding another layer of protection to a filtration system to assist in keeping my hobby room safer. @@ninjatango

[@NeoPest]

your layer of protection only works for non solvent paints and i think they were suggesting you should include this disclaimer. and even solvents smell can be reduced to low enough thresholds to not be sensed while the actual vocs in the room that have little to no odor are completely ignored as a current threat. the reality is very fine low micron physical filtration will likely trap most scent causing compounds as these tend to be larger chains and therefore physically larger contaminants to become trapped in the weave while the low odor causing solvents that are also more reactive tend to pass through. furthermore you are likely straining your boothgs fan motor and reducing the efficacy in the booth to pull paint in and not allow any to escape as these hobbyist booths are designed for ZERO restriction on the output. get dirty filters in AND out of your booth and you now have vastly reduced the suction and efficacy. and anyone reading this thinking of cutting up a perfectly good reusable shopping bag just to choke your shopvac motor and reduce performance : go buy a properly sized internal hepa rated debris collection bag that are sold for just about every brand and model and just throw it and all the dust away when suction reduces or it is completely full. they last a long long time, don't choke your motor and best of all are incredibly effective. i realize not everyone even knows shopvac hepa bag filers exist but these do not need or warrant a diy alternative they are just awesome. yes they cost 15$ but how valuable are your lungs? @@sgtatarms4780

no man you gotta crack the back window put the baby in the front seat and then get the car up to around 80. the smoke will move back to the rear and get removed . you can actually speed up this smoke removal by putting cups of water in front of your air conditioner vents. and while this was all sarcastic and should never be done, one use of aquarium pads that does work is flatulence abatement. seriously they sell underwear that has a pocket for a little piece of this lmfao @@ninjatango

Thanks for the advise. How well does the all black carbon filter fit in the slot of the first vent if it is doubled up?

[@barbatosrex9473]

If you double it up you should be fine

[@DarksouIjah]

I've been using your 5 gallon bucket method since you first posted it and love it. Super easy to make and works great. I am willing to bet that I have purchased more items from your videos than any other subscriber of yours... Take that as a compliment bc I follow a ton of modelers.

Awesome follow up to the extraction bucket video! Nice to see that you're listening to great music as well! Are you Greek by any chance? Barbatos is a Greek surname :)

I'm an Italian American. Barbatos is the name of a Mecha from the anime Iron Blooded Orphans. Search that anime and you'll see Barbatos

Although this is a good idea to vent your spray booth indoors it has a flaw. My spray booth fan is 270 cfm, when hooked up to this indoor filter box system it causes back pressure on the motor cfm to go way down. The suction in the spray booth at the filter is hardly noticeable. I know this because I tried it and got a face full of paint spray and fumes. It is like trying to put 5 pounds of air pressure in a 1 pound can. If the filter unit was a lot larger it would probably work ok. These units are designed to be used with dryers which have less air flow. This system would probably work but the filter box would have to be about 10 feet away from the spray booth fan resulting in lower cfm's from the fan and not causing back pressure.

[@gruvin4602]

Great video thank u very much...1 question I use tamiya acrylics and other acrylics and because I'm in the basement by 2 flame pilot lights furnace and hot water tank so it's not the smell I'm worried about it's the very fine flammable vapors floating around the air ?and if I wanted to use say spray can primers and oil based stink paints I call them😂 do these stop the flammable goods to be safe by open flame pilot lights?

[@ninjatango]

No. Follow the warning labels.

[@NeoPest]

no these would actually create a bigger explosion hazard as once turned off the solvents that do manage to become trapped in the water and in the pad will evaporate into the enclosed space of the filter box and rapidly go over the concentrations required for explosion. a small vapor trail could follow the draft created by the pilot light like a scene from pepe le pieu and boom. thank you for inspiring yet another reason to consider why this idea is awful, the video should be removed and an apology and correction video should be made

[@C.Brown5150]

Thanks for sharing this info with us... I appreciate you taking the time and expenses to show the choice's a person could have with ventilation.. Think I'm going to go with the first one.👍

[@HobbyBench]

None of these will do anything to filter VOCs, the best method is to filter into a canlite or similar carbon filter that is rated to the cfm of your fan. For instance the 6" canlite I use is rated to 650cfm if I remember correctly and it's like 20 pounds of carbon, but it will effectively remove 99.9% vocs and all fume scents. My most recent video on the kazio x innovation demos this. The water bucket method is pretty much ineffective from my VOC testing. @rex you should remove this video and actually do VOC testing against your solutions because all of these would be 100% ineffective. Ive actually tested the bucket trick and it doesnt work at all, it just moves your voc output. These cheap filters wont work either, you need a real carbon filter exhaust with 10-20 pounds of high quality carbon to actually spray in a poorly ventilated area with low VOC output. Saying otherwise is dangerous.

[@cr7chop]

This makes a lot of sense. Would you say that this method is only effective for water based craft style paints that are non toxic like Anita’s, folk art, apple barrel etc?

[@HobbyBench]

@cr7chop I did voc testing with solvents like acetone and lacquer paints and tested near 0 so acrylics would be fine

[@final3119]

@@cr7chop Acrylics and IPA is fine. The basic booth filter and a fan to pull it in is all you need. Don't even need to vent it out of the room or into a bucket.

[@DoghouseFunkBlaster65]

Thank You Robert, You really knocked it out of the park. If you can smell it, it means the molecules are still floating around in the room. No more dead canaries and budgies! 👌👍

[@NeoPest]

they are still floating around even if you cant smell it. usually you can rust your nose IF you smell something but rarely should you trust your nose if you DO NOT smell something. this is why extremely expensive electronic sniffers are required to be used to make sure a confined workspace is safe for humans to occupy. this is why canaries were used. their biology makes them extremely sensitive to changes in atmospheric gas ratios and physically react (die) at concentrations far lower than would kill a man in seconds. but these workers that didn't die in seconds still suffered permanent tissue damage often leading to painful early deaths and/or reduced physical capabilities when exposed to chronic sub-fatal levels

[@ClarenceObert]

Thanks Robert. I like the square one mainly because the input vent is on the top. The first one you showed that has it on the side is unfortunately on the wrong side for my set up in the garage. Now, if you run across a reputable fan assembly that can be used with "homemade" spray booths please share that info. Thanks and have a great day

[@NeoPest]

dayton brand externally mounted motor blowers. the 1TDR3 is most often used on small/average booths. youll need a round flange and either buy one off a guy who makes them (google "6fhx9 round flange" for this) or 3dprint one to connect to the hose. for a larger booth go with a dayton 1tdt2 but no one sells a flange so youll need to 3dprint one or imagine real well for a solution lol
