Filter Refill Pack


Made from meltblown polypropylene filter material, these filters will fit inside both sizes and all styles of our fabric face masks. Included are adhesive aluminum nose bar⁠s⁠—stick these to the filter before adding it to your mask pocket. Once you have the mask on, shape the nose bar to your nose for a better seal. We recommend using a new filter and nose bar each day.

Available in packs of 10, 20, or 40 filters and nose bars.
Check out our video on Facebook showing you how to insert the filter and attach the nose bar.

  • Precut filters made from meltblown non-woven polypropylene filter material

    Good filter - but...

    Hard to separate the individual filters w/o damaging them. Also, a mark where the nose bars went would help too.

    Convenient and easy to use

    Glad to have the option of extra filter protection for my fabric mask. The filters are easy to install and it's nice having an adjustable nose bar.

    Good filters

    Nice stack of filters. I don't have any good way to test how good their filtering capabilities are, but I like how they're all just a little bit stuck to each other, so o can move around the stack as a single item, not as a stack of many items.

    Easy to use

    Easy to use and install, only complaint is in my everyday use mask it was a little hard to breathe through all 3 layers. Still an awesome product and serves me well in this pandemic
