Enclosure ideas w/ Air filtration?

How has everyone created an enclosed system that filters the particles from prints? I have considered created an enclosure from clear polycarbonate, with a fan and HEPA filter on one side.

Things of Note:

  • Considering that some materials require stable air - the fan would need an on/off switch, only turning on after the print is complete.
  • Where can I find data on the size of the microparticles emitted? (to gauge efficacy of HEPA filters or soldering fume extractors)

RE: Enclosure ideas w/ Air filtration?

if you Google for Prusa enclosures you'll find a handful of commercial options, most--if not all--of which provide the option to add a filter. They're not cheap but if you print a lot of potentially dangerous filament types it may be well worth it. I can't recommend any in particular as 80% of what I print is PETG so I'm fine with a LACK enclosure for the occasional ABS.

I use a makergadgets enclosure - It came with a HEPA filter and active carbon filter built into the chamber, weather sealed doors and has an option for a programmable exhaust fan that I made a 2.5 inch duct adapter to fit.  The combination lets me run the enclosure closed (with the HEPA filter running) for printing ABS - this helps keep the temp up so warping is controlled nicely - and then the thermostatic exhaust fan will pull air (well above the print surface) out and let new air in.  The exhaust fan can be pre-installed so that it only exhausts air that has passed thru the HEPA and active carbon filter layers.  You can find their options at  It comes flat packed - you have to put it together - but that was part of the fun.  The folks at are very supportive, and run a small biz selling enclosures and related gadgets.

If your location allows it, even better than a filter is simply to vent the fumes to the outside. I added a clothes dryer vent to my wall and connected my enclosure to it. A fan inside the enclosure pushes the air out. This reduces the smell and health risks.
