N95 Face Mask Filter

thingiverse

Why:\At this moment, N95 masks are extremely valuable. The goal of BaileyMask is to create 4 filters (33mm x 75mm) from each complete N95 mask. What:BaileyMask has a tight seal around the face and a check valve system that reduces humidity inside the mask, thereby extending the filter's usefulness. The filter can be removed and sterilized with UV and hydrogen peroxide. The filter box is easily adjustable to allow air to freely bypass the filter when full protection is not required. Tips:This build requires a 3D printer. STL files are included. I will add SAT and X3D files soon. DISCLAIMER:I am not a medical engineer. Although I have tested this for myself, I cannot promise it will work for you. Please do not suffocate yourself or others, and do not expose anyone to coronavirus. Please follow these basic principles: 1)The filter must be N95. Anything less will not provide protection. 2)The filter must fit perfectly into the filter box and seal all around. 33mm x 75mm 3)The filter box must have a gasket (rubber band) and be held tightly to the mask. 4)Please ensure the mask seals tightly to your face. If it does not, you will breathe unfiltered air. 5)The straps should be elastic and adjustable (Velcro). Required for a good fit and comfort. Supplies: 1 - 3D printer and 75g of filament (I am using PLA) to create 3 pieces. Approximately 3.5 hours at the lowest quality. 1 - N95 Respirator mask (can cut 4 filters 33mm x 75mm) 1.5mm thick foam craft material for check valves a) Inhale: 37mm x 31mm b) Exhale: 39mm x 5mm Thin yoga mat or other rubbery membrane to make a seal to your face. Flexible adhesive, such as ShooGoo, to hold the Face-gasket to the mask and create hinges for the check valves. Materials for making straps: elastic, Velcro, string, needle, and thread. Cutting tools for the gasket and check valves.
