HOME Filter Modular Mask no Supports n95 HEPA MERV by vendevil
by Thingiverse
Last crawled date: 4 years ago
OVERVIEW:
Here's a modular mask for the Makers. I printed several masks available out there and personally was having problems printing many of them without supports. I'm getting advice from medical professionals, but this is in no way a scientifically tested or approved mask. Hopefully this is a last resort.
PROBLEMS / SOLUTIONS
There are a few issues I'm trying to I'm soIve with this setup:
problem (solution)
filters exposed (created a shield)
hard to breath (enlarged filter area)
air leaks around filter (screw setup with rings creates strong seal pressure)
filter material not sufficient (3 filter setup)
FILTERS
I'm using HEPA and MERV16 filter elements. Use medical grade HEPA, n13 or n14. WARNING! I've read that fibers from HEPA specifically can be dangerous. Please read up and learn as much as you can. I've added a post filter of dense cloth (Maybe cotton? I'm using a dense bamboo cloth)
The mask should have several filters in a specific order:
3D Printed Cap
Rough dust filter
3D Printed Ring Spacer
Home Filter
3D Printed Ring Spacer
Thick Cloth (to catch any particles from the Home filter)
SEALING AROUND THE MASK:
This is a nice setup for the sealhttps://www.thingiverse.com/thing:4256265
COMING IMPROVEMENTS
flexible printed seal
Better moisture protection for the intake
desiccant holder in the breath guard
