While a cloth mask alone provides a certain level of protection, disposable PM2.5 filters will filter out particles as small as 2.5 microns. Invest in the health and safety of yourself and others by using a PM2.5 filter. Each 5-layer filter is a combination of non-woven and meltblown cloth sandwiching an activated carbon layer. One size will fit in most masks that have a pocket area for a filter. 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.
