These Replacement filters are designed to be used in conjunction with
re-usable face masks to provide an extra filtration layer, specifically
against PM2.5 - Standing for for Particulate Matter 2.5 Micrometres
This particular type of pollutant can be increased by vehicles, power
generators, industrial emissions and chemical processing along with a
range of residential activities such as heating, cooking and burning
candles or fires.
Filters make face masks more effective, and should be replaced each time
you wash your re-usable KN95 mask.
