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.

How often do I need to change my B2 filters?

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. 


What materials is the B2 Mask made of?


FDA-compliant TPU and Polypropylene


Body: 84% Nylon 16% Spandex, Binding:  92% Nylon 8% Spandex, Stabilizer and Strap: UBL 89% Nylon, 11% Spandex


Meltblown and Electrostatically-charged polypropylene 


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

B2 Mask is currently only available in charcoal grey with a black overlay. Sign up for our newsletter at the bottom of the page to find out when additional colorways get released.


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.
