PM 2.5 Filters - Pack of 10
Pack of 10 PM 2.5 filters developed for our 4 Layer Reusable Bamboo Face Masks. Filters are designed to fit snugly inside the inner pocket layer of our reusable masks. The filters present a 5 layer fabrication from non-woven, meltblown and activated carbon.
- Our 4 Layer Masks have now officially been tested and scientifically proven to be more efficient at filtering out airborne particles than one-time use surgical masks. Filtering efficiency increases by more than 30% when paired with our PM 2.5 filters. Testing done in partnership with Sustainability Research Institute, University of East London
Filters are not washable and should be discarded after every 24-hour full usage or when they look dirty/worse for wear.
