Product Review

We designed our dust masks based on user input and included new design elements.
NOTE
When you use our mask with N99 filter, if you feel uncomfortable or breathless, remove the filter mask immediately.

What are some of the mask design improvements?
1，Unique ear strap design that suits a variety of face types.
2，The inner fabric layer is replaced with Activated carbon and Melt blown fabrics.

Why this mask with filter add two exhalation valves?
The exhalation valve design increases air flow and removes exhaled air from our mask, reducing condensation that causes fogging of glasses. (Exhalation valve can be disassembled when cleaning.)

Can I use a filter without this mask air pollution?
It is not necessary to wear a filter for daily use. It is recommended to use filters and our mask based on environmental conditions and wearer needs.
