We took this mask design and modified it by increasing the size of the strap attachment holes.

We also designed a special adapter, based on hospital and healthcare worker feedback, which accepts NIOSH & FDA Approved 3M Filter Discs.


If you already have a Montana Mask and don't mind the existing strap options, you can print out our adapter pieces only (Parts 2, 3 & 4 on Thingiverse) and follow our instructions on how to add the adapter to your Montana mask.

These masks are designed to accept NIOSH & FDA approved 4.3" Diameter 3M Filter Discs, but HEPA Filter Material from the local hardware store provides makes a great filter if NIOSH & FDA approved media is not available.

We are currently accepting donations for purchasing PETG 3D printing filament from Atomic Filament.

Please contact your local news media, high schools, colleges and libraries to see if they have 3D printers that can be used to print as many of these masks as possible.
