Mask Filter Insert Refill Pack
What are your filters made of?
The filters are made from non woven fabrics comparable to the ones used for N95 surgical masks.
According to tests from the Singapore A*star lab, our 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.
- 25 pieces per pack
- Dimensions: 13.8cm x 12.6cm
- To be folded into a triangle to fit into face masks.
About 7 working days for local deliveries.
I like that the filters are soft and cloth-like. Will recommend to anyone looking to get filters for their masks.
