FAQ

Frequently Asked Questions

Answers to some common questions about B2 Mask.

Does the B2 mask fog my glasses? 

B2 Mask is designed with a flexible seal that eliminates or significantly reduces fogged glasses. If you are experiencing any fogging, you can try flipping the nose seal portion to achieve a tighter seal on the nose. 

 

Does the B2 mask come in multiple sizes?

No, currently we have one adult size. If you need a different size mask, please click here to tell us!

 

What does the B2 Mask filter?

B2 Filters remove 99.6 - 98.3% of airborne particles down to .1 micron at normal breathing rates. This includes common contaminants such as dust, biological aerosols, and smoke. Download our B2 Filter Technology Review to learn more about B2 Filter performance and third-party testing at the University of Minnesota.   

 

How often do I need to change my B2 filters?

Please see the Use & Care tab for when to change your filters, based on what you use them for.   

 

Is the B2 Mask FDA or NIOSH-certified?

B2 Mask is designed to comply with NIOSH N95 standards per 42 CFR Part 84, but it is not yet NIOSH or FDA-approved.

Does the B2 mask come in any other colors or designs?

How breathable is the B2 Mask?

B2 Mask is very breathable for a respirator or face mask. However, it will not be as comfortable as wearing no mask at all. B2 Mask exceeds the recommended breathing resistance required by NIOSH for Filtering Facepiece Respirators. Light breathing (walking, desk work, driving) through B2 Mask will feel easier than heavy breathing (long flights of stairs, hard labor). If breathability is your top priority, consider purchasing B2 Filter Lite.

 

Will B2 Mask work with my beard?

B2 Mask relies on a tight seal between the mask and the user's face, and a beard or other facial hair may interfere with this seal. Still, whether you have a beard or not, wearing a mask is better than no mask at all.
