Mask Filters and Filter Replacements

There are different versions of our Everyday Mask, some of which have different types of filters or filter integration. This page explains which versions have which filters and whether they are sewn into the mask or removable. For more information on the specifications of each version, visit this page

Everyday Mask 2.0 (Sewn-In Filter): These masks feature sewn-in filters with lab-test certified BFE ≥95% and PFE ≥85% ratings. These filters were shown to maintain their efficiency for at least 20 washes, however we did not test beyond 20 washes.

Everyday Mask 95 (Sewn-In Filter): These masks feature sewn-in filters with lab-test certified BFE ≥99% and PFE ≥95% ratings for an even higher level of protection. These filters were shown to maintain their efficiency up to 20 washes, and to have PFE ≥85% thereafter. See the lab test results here.

Everyday Mask Versions v1.0-v1.4 (Removable Filter): The earliest versions of our Everyday Mask feature removable filters with lab-test certified BFE ≥95% and PFE ≥85% ratings. These filters were shown to maintain their efficiency for at least 20 washes, however we did not test beyond 20 washes.

Everyday Mask Performance v1.5 (Sewn-In Filter): These masks feature sewn-in filters with lab-test certified BFE ≥95% and PFE ≥85% ratings. These filters were shown to maintain their efficiency for at least 20 washes, however we did not test beyond 20 washes.

Replacement Filters

Everyday Mask versions 1.0-1.4 have removable filters. At this time we do not have replacement filters available for sale. In terms of third-party filter replacements, we recommend using meltblown non-woven polypropylene filters that do not exceed 6” x “4 in size.
Our removable filters look like this:
