We have disposable filters to go inside our masks. (masks are listed HERE)
We are running low on the charcoal impregnated PM2.5 filters, but now have Nonwoven Meltblown Filter Fabric that we will be supplying as double thickness (2-ply) filters. We will be including one of these in every Mask order automatically (you don’t need to select it here) but please add more to your cart if you would like additional supplies.
The meltblown filters have an element of particle filtration and are useful for trapping moisture and droplets. To my knowledge, the particle filtration is not fine enough to capture Coronavirus particles and we make no such claims, but it should serve some purpose for droplet-borne particles.
