Will filter most particles a 3d printer produces.ĬON: ABS headaches are not from particles, but Volatile Organic Compounds (VOCs), that are two orders of magnitude smaller than any particles a HEPA or ULPA could trap - they’re essentially gasses. PRO: Plug and play! High air flow (mostly). Here’s a short list, and why I eventually settled on creating Nevermore: There are many options for 3d printing air filters. If you plan on using only a Nevermore - be sure to seal your chamber as good as possible to prevent diffusing. And that air could be zero-per-cent cleaned. Meaning, as nothing pulls air into the chamber, air can diffuse freely to the outside through any remaining gaps. Some will have a hard time achieving a good chamber seal, which creates the biggest drawback of recirculation filters - they're air flow neutral. The number of passes you get all depends on how well you can seal your build chamber. A worn-in 50% efficiency recirculation filter achieving four passes would still remove 94% of the bad stuff.

(credit: Characterization of volatile organic compound emissions from consumer level material extrusion 3D printers (2019)) VOCs (Volatile Organic Compounds) are common in daily life but VOCs generated from 3D printing are known to cause severe health issues and even cause cancer in some cases.Ī study from 2013 of ultrafine particle emissions from desktop 3D printers (2013) is a good start to understand the importance of your filament choices and the printer's environment.
