What are your mask filters made of?
The mask filters are made from non woven fabrics comparable to the ones used for surgical masks.
According to tests from the Singapore A*star lab, our mask filters have 95.5% - 99.8% BFE reading after 15 washes, which means they retain their efficacy fairly well even after repeated washes.
We recommend that you change the filter after 10 washes.
