Double One-Way Discharge Valves

The silicon sheet in the vent valve will seal itself when you breathe in. Then you will take fresh air through the filter. And the air will get out through the vent valve when you breathe out.

And we choose premium nylon material and upgrade mask designs for the best comfort. You can easily adjust the soft nose clip inside the filter, and the adjustable neck strap to get the best fit for your face.

How to change the filter correctly?

  1. Hold the inner vent valve with one hand, and gently dig out the valve with another hand to separate the filter and mask.
  2. Align the new filter with the mask.
  3. Align the inner vent valve with the filter and mask.
  4. Press the outer valve slightly to lock the filter and mask.

  • Larger Mask Shell

    We enlarge the mask shell around the chin to reduce the mask friction to your face and throat. And premium nylon material provides better comfort.

  • Special nose clip

    Compared to the hard nose clip installed on the mask of others, we installed the softer nose clip into the filter. Such a nose clip is easier to be adjusted and can create a firmer seal, which helps to reduce the possibility of glasses fogging.

  • Soft Nose Pad

    Exclusive soft nose pads provided with the mask can be attached to the filter. It can effectively eliminate fogging on glasses and reduces pressure on your nose. You also can easily remove it if no need.


1. Please be aware that our masks only filter the air breathed in, and will not filter the air breathed out. It can not protect those around you.

2. The dust mask shell is just a holder of the filter, so its material only affects comfort and will not affect filtration performance.

3. While we make our every effort to upgraded the dust designs to prevent glasses fogging, we cannot promise 100% no fogging.
