PM2.5 replacement filters are designed to deliver 5-layer protection against harmful air pollutants. PM2.5 refers to atmospheric "particulate matter" (PM) that have a diameter of 2.5 micrometers.
PM2.5 filters contain five distinct layers to maximize protection:
1. Anti stick layer
2. Filter cloth
3. Activated Carbon
4. High efficiency filter cloth
5. Anti stick layer
Size: 12cm x 8.5cm. Available in packs of 25, 50 or 100
USA & Canada: $8 USD/$10.40 CAD Europe & ROW: $12 USD
The CDC is recommending the daily use of cloth face coverings in public settings where other social distancing measures are difficult to maintain, like grocery stores or pharmacies and especially in areas of significant community-based transmission.
Adding a PM2.5 replacement filter will improve the effectiveness of your cloth face covering, but it is NOT equivalent or considered a substitute for medical grade surgical masks or N95 series respirators.
PM2.5 filters are NOT intended for use in surgical or clinical or healthcare settings.
