Infamous face mask

The Filter Face Mask by FNDN ("Foundation") is our top of the line mask in personal protection equipment (PPE).  Convert this mask into a PM2.5 surgical mask by inserting an FNDN 5-layer, non-woven, melt-blown filter which filters 60% - 65% of pollutants (filter sold separately here on our website). While the Filter Face Mask by FNDN is washable and reusable; the filters, like medical masks, are single-use and disposable. For maximum protection, you should dispose of your filter before you wash your mask.
