3D Printed Air Purifier -- gets rid of the smell of ABS and toxic VOC's

- HOLD UP: A few people smarter than me commented and noted that this doesn't get rid of UFP's (ultra fine particles) This respirator cartridge has a P100 filter in it but some of the super fine particles will still get through. It still does get rid of the smell and VOC's namely formaldehyde which is a carcinogen. There isn't much you can do for the UFP's except make sure your chamber is sealed and/or vent it to the outside (best way). Just thought I'd let ya know :)
Hey everybody! So I recently got a new 3D printer ( Prusa i3 mk3 ) and I wanted to use it in the basement so I didn't have to walk out to the shop at 3am to start a new print for a customer. And since it's not particularly healthy to breathe in the "fumes" that come from the molten plastic, I did a few things that likely remove them altogether!
First I made an enclosure (first major step) and in this video I designed and 3D printed an air purifier that gets rid of a bunch of that nasty stuff you might encounter when you are around a running 3D printer. And it only cost ~ $50! It's extremely easy to print and uses easy to find and easy to replace respirator cartridges! This particular one I used is a "3M Formaldehyde Organic Vapor Cartridge/Filter 60925, P100 Respiratory Protection" which, as far as I understand, is the best type for this application. Anyway, I hope you enjoyed this video and found it useful! Thanks for watching!

Pro tip. Keep the spare filter in an air tight zip lock bag. It breaths even when not in use, so without proper storage. The filter is worn out when you're ready to replace the old one.
Good advice! Thanks for the tip!
This was a phenomenal idea! I signed in just to comment and thank you for making this video. I have been wanting to build an enclosure for my Ender 3 V2 for a few weeks now and was completely confused as to which route to take and came across those expensive BOFA filtering systems for $1000+ and seriously considered it until I saw this video. This was such an informational and helpful video. Thank you so much and keep creating things!
Thank you! I appreciate the kind words!
Man, thank you so much for this video. I am in the same spot as you were, cant vent outside and was trying to find a solution, yours is just brilliant. I have a resin 3d printer and the fumes can be really bad, not sure how bad compared to PLA, but for sure something to get rid of. Thank you man for sharing all this great info, parts and designs, this solution was brilliant.
how did it went with this solution?
Very nice! Working on my enclosure now, and gives me a lot of information. Thanks
Nice build, I think ill use this in my situation. Using an old enclosed computer cabinet in my living room, due to having a small house. I wanted to start using ABS but needed to keep the air clean for obvious resins. Since this just filters the air side the cabinet it'll help keep the noise contained as well. I also think ill use this basic idea to run a, separate, HEPA filter in the cabinet ass well. having a separate HEPA should also extend the life of the "fume" filter.
Thanks for the inspiration mate! I just knocked up something similar using a centrifugal fan salvaged from a Cisco 24-port switch and a cylindrical P2/A-Aus facemask cartridge. Probably does little for UFPs, but it's better than nothing.
Dude, that's exact what I need, great work!
Great work on that design!
Thanks!
i havent printed anything yet. I have a mini 8k s (resin). I should be able to print this part easily yes?
You don't need to vent it to outside of the box. Just install the device inside the enclosure and let it continuously filter the air inside of there. Keeps inside warmer too!
that's what i was thinking! i'm going to make something similar!
Unless the enclosure is air tight, he would need to filter outside the enclosure to create a negative pressure inside the enclosure.
This is what I needed. Thank you, you're a life saver!!!!!
Very helpful project, maybe the best position is in center on the top.
I was looking for this vidéo since a while! Thx
Also nice job with the modeling. Great idea to use a photo, did you put a calibration ruler / measurement in the photo? How did you ensure there was no skew to the photo that would push measurements out one side of the picture? Interesting!
Thanks! Yeah I measured the fan and then defined that dimension in fusion. It helps to take the photo as square and strait on as possible to avoid any distortion.
Nice! I just bought a 12v PC fan and a bunch of vent tube to pump air out of my enclosure.. till I realized that would pump heat out too. I can just adapt your filter mounts to my fan mount, so thanks for the video and the designs!
Glad I could help!
I use a Levoit air purifier instead but this mod is a pretty cool, simple and heap idea, especially for resin printers you can just place that inside the resin printer, well done.
BEAUTIFUL!
Thanks!
I took the lazy way and bought a small enclosure, but then I 3D printed a mount for a small hepa filter, then ran that to an inline fan with 130cfm rating and it's done very well so far, noticeable difference in air quality.
Sorry if I missed it somewhere but how long does the filter last in the enclosure ? :)
great idea. I have just ordered one of these: a "DC12V Vacuum Pump High Pressure Diaphragm Air Pump 12L/Min Noiseless" as I wanted be sure I am getting the air throughput (diaphragm creates a seal as it is pumping rather than relying on the implied suction from an impeller) - just a suggestion/option - hope my comment helps
Great idea! Lemme know how it turns out!
Hi Darren, you might want to consider Odourcube, saved me a lot of time odourcube.com .
Good idea! Have you figured how lone these filters wood last before having to replace.
Must be planning on getting another printer with that size enclosure, ; ) Also does the fan pulling air out reduce the temperature in the enclosure. Doesn't seem to effect the prints if it does. I've seen some people circulate the air back in after going though the filter. Great video, Thanks.
I want to make an enclosure for my printer but I only print in petg and pla so I don’t need the heat. Does this fan sorta cool down the enclosure while it’s filtering?
Very nice video!
What 3D modelling software are you using?
Fusion 360 is what I use.
Great idea! Don't suppose anybody from the UK has designed their own version? As those parts are not available in the UK and shipping would be expensive lol. There are similar products but the fans I'm finding all have pin adaptors and the mounting holes are completely different, so I'd have to design a filter attachment for whichever one I pick. And then not sure what power supply I'd need for the pin adaptor :S
I don't have the space for a cabinet like that, But I'm still looking for a small enclosure for my Mars 3 and my FLSun SR. Not having the best of luck finding one suitable. :)
is there link to the adaptor you used to mount the fitter to the fan?
Do you think that a hepa and carbon filter solution would work better?
I know good carbon filters and hepa filters can filter a lot of vocs and ufps
I've been told that the p100 filter is considered HEPA.
I'm pretty sure you could hook up that fan to the printer and in firmware program it to turn on when a print is going, but that's another step for another day. Good stuff tho!
Could you please provide information on what screws you used. And thanks for the work, great job!
I believe they were #8-32 bolts 👍
@@HappyMadScientist thank you very much!
awesome design how often do you find you have to change the filter?
Thanks! Results vary with what types of filament I’m using but I wanna say that I usually get about 50-70hrs out of it before I start to notice it degrading. I personally keep them for a couple hundred hours until they hardly work anymore.
@@HappyMadScientist oh that's good I just didnt want to be replacing them every week or so.Thanks alot great design
Yo! How do you put a pic behind the model? That’s dope
Thanks! Open Fusion 360 and go to “insert” and click “canvas”. You can right click it to make changes and calibrate it. There are some tutorials on TH-cam that are super helpful too.
Great video! Also nice to see people using fusion. How long have you been using fusion 360?
started in tinkercad and quickly outgrew it. been using fusion 360 for about 2 years now and I've found it very useful!
Can you show us how and where you put your power supply for the printer? I have an enclosure I am building soon and am wondering if I need to move the power supply from the enclosure.
Yes, I would move you power supply out of the enclosure. Power supplies are supposed to last a lot longer if they stay cool. There are directions on Joseph Prusa’s channel for removing the power supply. I put mine just below the surface. Hope this helps!
Nice work. Did you use Fusion 360? I've only ever used Sketchup, but now that I've seen how you can incorporate a photo to aid the design, I want to learn that too.
Yeah totally learn to use fusion 360! It’s worth it! The learning curve is kinda steep but not too bad and there are plenty of tutorials on TH-cam that are super helpful.
Very nice idea. What cad software you used foor the adapter? You have good cad skills, keep developing them.
Thanks! I appreciate the encouraging words! I used Autodesk Fusion 360 which is pretty much the same CAD software as Autodesk Inventor in my opinion
I like the idea but how much force is there on the fan
Awesome. I am going to make one of these! I will report back with results!
I am looking to make enclosure for my SLA printer and this is the most elegenat solution i have found. Others suck so bad. I am open to buying fume extractor, but there is no guarantee that the filter in fume extractor is god enough for SLA fumes. So basicly, all solutions come to the filter choice in the end. I have researched slightly and found that the 3M 6099 offers most protection in combination filter. It is Rated A2B2E2K2HgP3 R + formaldehyde. I am only not sure why are there two different types of filters (60925/60926 and 6099) when both can be identified with ABEKP standard. Anyway, 60926 and 6099 should both be fine for most part leaving only
hi would you tell me what software did you use to print that part in this video?? thanks
CAD/CAM - Fusion 360
Slicer - Prusa slicer
@@HappyMadScientist thanx bro
Do you have a file for the chain? 😬
Hi by any chance do you sell the 3d print part for the respirator? I'm super interested in buying one because I'm gonna make a set up for a printer that I'm getting for my brother.
Yeah I can! Planning to put to put 3d printed parts on my website for ppl who don’t have 3D printers in filter projects. I’d be happy to print one out but if your getting him a printer it would be good practice for him to try and print it out himself imo!
would you be willing to share the plans for your cabinet?
If I had plans... I kinda just through it together :)
I will be making this very soon for myself… need to make an enclosure first.
Any thoughts or comments about if I were set the fan up to exhaust out of the enclosure??? Probably wouldn’t make much difference correct? The reasoning is I want the option to hook up some sort of duct to carry the air out a window if I feel so inclined…
So if you exhaust out of the enclosure, you will have a harder time keeping the air inside of your enclosure warm. This may increase the chance that your prints will warp. If you do vent to the outside, try to do it in a way that allows as little air movement as possible move over the actual plastic of the print as that could also cause it to warp.
The fan pulls air through the filter, where does it exhaust? Back into the enclosure right? Does it exhaust radially outward? Also, what modeling software are you using?
Yep it just recirculates the air back into the enclosure. Fusion 360 is what I use and recommend
@@HappyMadScientist thanks for the info. I'm looking to get my first printer, looking at E5+. Is there any concern with temperature? When people come up with solutions to exhaust their enclosures to get rid of fumes, I always wonder if heat loss becomes a problem. Any thoughts? Thanks
@@jakemouser2214 I'm not super familiar with the E5+ so I'm not much help there. I always recommend the prusa i3s because they are so darn easy to set up and use compared to others I've used + they are so reliable.
Yeah large printers might suffer from heat loss. A sealed chamber helps a lot. imo if ur exhausting the air, your airflow should be as minimal as possible. Just enough to keep a slight negative pressure inside the chamber.
Anyways hope that helps! Good luck with your 3d printing endevours!
Awesome enclosure, do you have any plans for it?
Thanks! I want to get another printer eventually cause there is room for it.
Great video. I know it's a little older of a video but wondering if anyone can share some information about how well this is working? I have a sealed cabinet I wanted to vent but this might be alot easier.. Im going to try but i hope others have had good luck with it.
Let me know if you build it and how well it works. I was thinking about it as well.
I did make this filter and it did seem to work ok.. I then upgraded to a 14 canister filter which draws air in from a 4in vent fan.. then filters and pushes the air back into the cabinet.. this does very well with abs fumes. Again with those nano particles I’m sure it captures some but not all. Over all the larger filters way more air and does a better job.. but this video helped me get there so thank for the video and happy printing
@@daveolson9424 If you haven't, you should make a video on this. Sounds pretty cool.
great idea
Thanks
Couldn't you use water as a trap/filter along with this. Have the airflow blow across water to capture ultra fine particles?
Interesting idea - wonder if anyone has done that, like a small dish of water? I live in a dry climate but for some could add moisture to the filament.
Thank your helpful turtorial share very smart idea for exhaust gas inside ,may i know what app or software use to draw 3d modeling thank
Dumb question what software was that? Fusion360 or freedCad?
Fusion 360 - not a dumb question :)
Whoah, I know this video is older, but I gotta know what cad software was used. Having the ability to drop a photo overlay when making your part changes the game for me.
What is that CAD software?
I use Fusion 360 for everything CAD and CAM related! Yeah I agree! Dropping a photo in and calibrating it to be “true to life” size in CAD is super useful. There are some good tutorials on how to do it in Fusion360 since it isn’t super intuitive
Well done
Thanks!
What cad software did you use?
Fusion 360

Move Like This
By: Jules Gaia
Thanks for the follow. Nice work on the air filter. My Prusa i3 MK3 will be here soon.
you should order another fan and use at least both of those filters. that's a lot of air volume in that enclosure for even just 2 of those. I'd imagine you'd probably need about 8 of those filters and fans to be adequate for the use case of having that much air violume inside the enclosure, plus running a fan for long periods in a filter like that will likely use up the filters much more quickly, so if you used more filters with a lower fan speed, that may be more effective.
So has anyone used something like this with a laser engraver as they produce a lot of smoke and how did it do if not may make it to try with my laser engraver
I like your setup. However, I wonder if it would be better to recirculate the air through a filter within the cabinet instead of exhausting it. 2 reasons come to mind is , There is no reason I can think of as to why to exhaust the air within the cabinet.and the other being, if your trying to hold a higher temp within the cabinet it would be counter intuitive to exhaust the heat. Just a couple of thoughts that just popped into my head.
it would also do a better job, since the air to pass through the filter would do more passes.....
also why choose to filter out organics instead of the chemical branch of filter 🤔
Formaldehyde is one of the main things I’m trying to remove. It is an organic compound if I’m not mistaken.
This idea is just idiotic istead of just using his brains he used his stupidity to create some nonsense that wont work work...garbage idea
Hi dose t-pla smell tough pla or abs is the worst smell
OH OH OH Yes! Much better than what I had planned! Canceling amazon orders and changing directions now!!
OH! I'm going to add the PMS7003 sensor to a nodemcu/esp8266/tasmota micro controller and have it turn on and off the filter when it detects particles!
I am in no way an electrician but does anyone know of a on/off switch I could put between the power supply and the fan so I can power turn it off and on without just unplugging it and plugging it in?
That is a sweet enclosure man. Putting the air filter high doesn't make sense to me though. VOC's are heavy, cool fast, and stick together so I would think they will sink and settle into a dust in the enclosure. (Not that I am actually worried about the safety of the enclosure or anything. You did a bad ass job)
Thanks man!
I made a few devices somewhat similar to yours early in the pandemic to protect me during dental visits. Initially I used 3M #60923 filters (what you used), later switching to ones that filter only particulates (VOCs aren’t the problem in healthcare settings).
My initial fan was visually identical to what you used. I found that it and a better alternative - what I’m now using - are very sensitive to intake restriction. Using one filter significantly slashed the output airflow. To provide sufficient airflow for my intended application (dental), I used six to nine filters. The output airflow is much better with nine filters but still is noticeably reduced. That isn’t surprising because fan blade design is optimized for no additional intake resistance. If I had time, I would engineer my own fan so it could, for example, generate better intake suction.
I’ve begun measuring particulates generated during 3-D printing, but my particulate counter (and most others) cannot detect ultrafine particles, which are generated during 3-D printing. The big question is: do 3M and similar small particulate filters substantially reduce ultrafine particles? I will continue researching this and perhaps make my own ultrafine detector.
Most HEPA filters markedly reduce PM2.5 and larger particles but usually are much less effective against ultrafine ones. As a physician, my concern is that standard particulate filters may provide a false sense of security. Yes, they help, but do they sufficiently mitigate ultrafine particles? That is the greatest risk, so I will continue investigating this.
fyi check out Dyson air purifier filters: they catch ultrafine particles, and have a life of 12 months in the Dysons. If you were to match the fan strength to the relevant Dyson fan, that might work? Or just buy a Dyson if you can afford one, the larger the better. They specifically claim that this filter catches viruses.
Check out 3M Filtrete MPR 2800 filters. They are expensive but they're designed to filter out ultrafine particles so AFAIK it's the best solution for filtering with 3D printers.
Impressive.
Thanks!

Happy Mad Scientist Thanks!
Wait so did you also make that cabinet??! #HappyMadScientist
Yup.
It’s an awesome cabinet!
Cool idea on the adapter. It would be interesting to get some concrete data on whether it makes the air safe or not. The cabinet looks great, but man... thats one big fire hazard. You even have multiple spools hanging out right above the printer. I would hate to see this go up in smoke.
Thanks! If you want data check out the filters safety data sheet.
Thanks for your concern... but contrary to popular opinion 3D printers are very safe as long as they aren't cheap Chinese printers. The hot-end on many printers don't even get hot enough to auto-ignite paper.
Was wondering if anyone has tried this with SLA printers in the cabinet.
Not sure... check the data sheet on your resin and the filters?
@@HappyMadScientist I don't have one yet but looking at solutions if I do. The resin datasheets I've looked at I don't cover the smell or toxins except that you should wear a mask. Most TH-cam reviews talk about the same.
@@thenam3less maybe it'd be best just to run a vent to the outside? You don't need to maintain chamber temp do you?
@@HappyMadScientist I live in Arizona. Don't want to have heat getting into my house or heating up the prints.
@@thenam3less I feel like you can have two fans. One blowing outside of a window and the other blowing into the conditioned air in the home into the enclosure. I don't think with the fan acting as an exhaust, will bring heat back in.
💀did u screw the fan on the wall
Can you make one for 120mm computer fan?
if I had one yeah.
@@HappyMadScientist you don't have a standard size computer fan? wot.......
So how is it working? Do you need to change the filter often? I just ordered my Prusa i3 MK3S 3D and have about a month to collect everything. This only filters the air, correct, it doesn't drop the temps in the enclosure?
It works good. I use it every time I print with ABS. How long it lasts depends on how often you’re printing and how much use you want to squeeze out of each filter. For me I’d say I use em about 136 hrs before I change the filter but that is pushing it. Yes it just recirculates the air already in the enclosure. Good luck with your new printer! Hope this helps!
Wish the filter wasn´t so damn expensive, one filter cartridge cost almost 50 bucks.
probably nitpicking, but I suggest you get a camera stand or something to fix camera onto.. all the shaking makes me (and potentially a select few other viewers) dizzy
but otherwise great idea, thanks!
Thanks for the feedback! Which part of the video are you specifically referring to?
I have exactly the same issues, I sleep in the same room as the printer. I may change this. I was going to buy a purifier but may try to make my own. I see you have a piano that looks exactly like my one, the Roland FP-3 right? Not very common, but I think it's very good!
Good luck finding any filters now haha.
Yep! It’s my dads. I like it a lot!
Great idea I think I'm going to change the design of the filter cartridge and also use activated carbon with the appropriate filter. Good job.
Thanks! And that’s cool! Lmk how that activated carbon works!
Although I appreciate you trying to help the community, this air scrubber does not work effectively. Ordered the material and printed your adapter and I get nearly zero air flow out of the fan. There are several other air scrubbers that use small HEPA filters and pelletized activated carbon that look to be far better. If your thinking about making this, don’t, it’s a complete waste of time and money.
Sorry to here that. It works fine in my chamber. Maybe check and make sure the hot glue “gasket” is sealing properly.
Could be that your chamber is not sealed well either. While the airflow isn’t going to be that impressive, it should be plenty for a decently sealed printer chamber.
I’ve bought the other filters you describe. Specifically HEPA filters. They don’t get rid of all UFPs or any VOCs or smell as far as I know. The cartridge I used (which is technically HEPA) gets rid of most everything (including the smell) cept some very tiny UFPs which a HEPA filter is incapable of catching as well.
Thanks for giving it a try. If ya make one that’s better let me know and I’ll link it in the description.
@Matthias Stegert Not sure but it seems they last about 60hrs before the airflow starts dwindling and maybe 100hrs before they stop working. Some times they last longer and others not as long.
Really solid idea but apparently does nothing about the VOCs and ultrafine particles. But I'm gonna piggyback off your design and create an airduct adapter to vent fumes under my garage door. So good work in any case!
Thanks! It should work with VOCs but the jury is still out on whether or not is effective with UFPs. The best is to just vent it to the outdoors if you can.
Respirator replacement filters on aliexpress for $10 should do it
If I had the patients to wait for shipping haha
@@HappyMadScientist I like to just order things and wipe it from my mind, then have a happy surprise in 2 months.
hepa filter doesnt do shit with fumes lol. u need carbon
Did you read the safety data sheet on those air filters?
You sound so nervous and almost embarrassed to explain why you want to have this. I know this video is really old, but studies have even gone farther to show that there are carcinogenic vapors that are released from heating most filaments high temperatures. so nothing to be worried about. I actually think this box does almost nothing to protect you from that in the long run since it is an airtight sealed. It's just a standard cabinet doors with air gaps all around. Most of it would probably leak before that. Air filter caught anything. But like you and everyone else says it's more of a concern if it is in an interior. Highly used room and running almost all day.
Car air filters are much much cheaper and work as well. They also have a better size to use with usual computer fans.
Umm, the fan is rated for 12V 0.95A, but the adapter that you are using is a 2A. (Just letting you know :D)
Well the way it works is the fan should only use .95 amps of the available 2amps. So it should be just fine. Thanks tho👍
Well, that I totally forgot😅
Haha no prob.
Get to the point, please.
