What was the B2 Mask designed for?

The B2 Mask is the result of 4+ years of human-centered product development, originally geared towards protection from air pollution, smog and wildfires. The B2 design was adapted during the Covid-19 pandemic, with the removal of the exhalation valve to cater for the growing respiratory protection needs of global citizens.

Who designed the B2 Mask?

Behind the B2 Mask, there is a team of designers, engineers and medical-device specialists with the goal to create a low-waste, durable alternative to N95 and other disposable masks. The result is N95-level protection in a sustainable, lightweight design that is ideal for extended lifestyle use. Read more about our team's values here. 

Is the B2 Mask sustainable?

The B2 Mask is made from durable materials that can be washed and reused hundreds of times. Using B2 Filters is more affordable over time than disposable masks, and reduces waste by up to 80%.

Where is the B2 Mask produced?

The B2 Mask is designed and produced in the USA. We work with ISO-certified manufacturers and suppliers based in the Midwest to ensure the quality of all of our products.
