These replacement filters are designed to be used in conjunction with
reusable face masks to provide an extra filtration layer, specifically
against PM2.5. Standing 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.
Are these filters washable?
These filters are not washable. Filters make face masks more
effective, and should be replaced each time you wash your reusable KN95
How long do the filters last?
It depends on the usage and exposure. If you are wearing the mask
all day it would be recommended to replace the filter daily. If you are
wearing it for a short period of time, such as going to the shop, then
the filter will last much longer.
