5-Layer Filter (Pack of 20)
Our premium PM2.5 filters have an activated carbon core designed to manage odours, pollutants and volatile organic compounds (VOCs). Four additional layers each help to filter out particles as small as 3 micrometres, more than 100 times thinner than a human hair. Our replaceable PM2.5 filters are compatible with the entire mask collection.
Our Nanoknit Masks are designed to provide a barrier between the filter and your skin to deliver enhanced comfort, while offering a more durable shell that protects the filter from the outside environment.
Please note: Nanoknit is not designed for medical applications. For health and safety reasons, all face masks and filters are not eligible for exchange or refund.
Nanoknit masks have a hidden pocket at the bottom on the mask to insert the filter and position it horizontally. The lifespan of the filter depends on the usage and level of contamination. Change filter if it is visibly dirty or becomes difficult to breath. Filters may be used continuously for up to 24 hours or occasionally for up to one week. Filters should be stored in a cool, dry place and may not be washed.
