Description
Designed to function as a basic HEPA filter for inhaled and exhaled air through a Scott AV2000 or AV3000 full-face mask. Converts a SCBA mask to a respirator. Will need two one-way valves (https://www.amazon.com/gp/product/B01NCJP9QN/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1).
No supports are required. Just print the four pieces, put them together with some filter material, the two valves above, and attach it to your mask.
