Montana Mask Filter

thingiverse

I designed an enhanced and more effective filter with a larger surface area, making breathing easier. This Filter is compatible with the Montana Mask (visit makethemasks.com). Simply insert your preferred filter tissue, press it together, and secure it with tape for a tight gas seal. Additionally, like in the classic design of the masf with its filter frame, you can add a secondary paper or material (recommended for added sealing) to further improve filtration. Stay safe!
