B2 Mask Features

Comfortable and leak-free

The B2 Mask’s ergonomic facepiece is made of soft, FDA-compliant materials that conform to your face shape. The result is a comfortable, protective, and anti-fog seal.

More protection, less waste

The B2 Filters provide excellent protection, and are a more sustainable and affordable option that are mailed directly to your door.

Sleek, portable design

B2’s patent-pending facepiece features a hinged design that allows B2 Mask to fold down flat for easy storage in a bag or pocket.

Performance meets style

B2’s fabric overlay is made of a performance mesh that ensures breathability and keeps your face cool. The design is modular, with new colors and styles coming soon!
