Mask for cloth or HEPA filter (V2), with clip

thingiverse

I designed this mask to offer some protection while keeping the filter material fine enough for comfortable breathing. Existing designs either used a small filter, making every breath a struggle, or two separate filters, adding unnecessary complexity and weight. My contribution is a single-filter design that provides ample surface area. To achieve this, I'm using a HEPA vacuum cleaner bag cut into a suitable size. During non-strenuous activities like grocery shopping, I've found it to be quite comfortable. This 3D printed mask was created with Tinkercad and can be edited online at v1.tinkercad.com/things/9JWwxI2Xp8Z.
