Make Your Own Mask Filters
Open Air Filter
1
Pull cardboard away from filter
2
Avoid glued areas by cutting about an inch in from filter edge
3
Flip over and gingerly pull off remaining cardboard
4
Lay your No-Sew mask out and roughly cut filter to size
5
Smooth out filter and place inside mask flaps
6
Almost done, just add back your rubber bands, fold in, and wear normally (strange to write that)
