Re-usable Face Mask Filters

Disposable PM2.5 filters will filter out particles as small as 2.5 microns.
Each 5-layer filter is a combination of non-woven and meltblown cloth sandwiching an activated carbon layer. The filter slips easily into the inside pocket of all RainCaper reusable fabric face masks.
The disposable PM2.5 filters should be replaced after 5 to 7 days of use.
Filters are sold as a pack of 10 which arrive in a hygienically sealed poly bag.
