FAQ

What do our facemasks filter?

Our masks have been proven to have a >96% filtration of 0.1 micron particles through rigorous independent lab testing. We are happy to share our test reports with you upon request.

What are the masks made of?

Our masks consist of 3 layers of polypropylene based, non-woven material. They have an inner hydrophilic layer to wick moisture from your face, a middle filter layer, and a hydrophobic outer layer to repel moisture and debris.

Are these masks washable?

Our masks are not washable. Like all high filtration masks, washing them will destroy the filter. 

How long can they be worn?

Our masks can be worn for 72 hours of wear time. By wear time, we mean 72 hours of you actually breathing through the mask. If the mask gets damaged or wet, dispose of it and use a new one in case the filtration is altered.

Do you make kids sizes?

We make child sizes that will fit most kids ages 6-13. Please keep in mind that our masks may not fit all children due to the high variability in face size. Tying a knot in the ear loops can help to tighten the mask.

Can I see your test results?

Sure. You can find our Particulate Filtration Efficiency and Bacterial Filtration Efficiency test results at these links. Some information may be removed for privacy reasons.
