B2 Mask uses the latest advances in filter technology that provides around 99% filtration against a range of airborne contaminants down to .1 micron.
Comfortable, airtight seal
B2 Mask provides unparalleled comfort compared to existing face masks. Built from FDA-compliant materials, B2 folds in half for easy storage with a novel flex-hinge design.
Durable, reusable design
B2's facepiece is constructed from durable materials and is easy to clean by hand or in a dishwasher. The fabric overlay can be cleaned by hand or in the washing machine for easy maintenance.
Sustainability & Impact
B2 Mask uses the smallest, most affordable high-efficiency filters on the market that reduce filter waste by up to 80% compared with disposable masks. A portion of all B2 Masks sold enables us to donate masks & filters to communities in need.
