Nanofiber Filter 5-Pack

$14.99 $9.99

Our four-layer nanofiber mask filters utilize nanofiber filtration technology. They filter micro-pollutants as small as 0.3 μm. Unlike traditional filters (including surgical masks and N95s), nanofiber maintains effectiveness in humid and wet conditions such as rain, sweat, and condensation from breathing.

  • Replacement nanofiber mask filters are available in packs of five.
  • Choose the filter size that corresponds with the size of your mask skin. For example, medium filters insert into a medium NanoFit Mask.
  • Large and X Large masks both use “Large” filter packs
  • Filters come in a resealable bag, storing them securely until ready for use.
  • Recommended use for up to 15 days per filter, at 8 hours a day (120 hours).

SUPERIOR FILTRATION

  • The NanoFit Mask’s four-layer replaceable filter utilizes nanofiber filtration technology.
  • It blocks micro-pollutants as small as 0.3 μm (microns).
  • Unlike traditional filters, nanofiber does not depend on static electricity to filter effectively. As a result, nanofiber filters last significantly longer.
  • Nanofiber filters maintain their effectiveness in humid conditions, such as rain, sweat, and condensation produced from breathing.
  • The NanoFit Mask combines layers of both nanofiber and traditional filtration to provide optimal protection.
  • Our electrospun nanofiber is better than meltblown filters in regards to consistent fiber size, comfort, and breathability.


In addition to the 4-ply filter, the NanoFit Mask is made of 3-ply ViralOff®-treated fabric to provide optimal mask protection.

Hi Fatima, thanks for your review! Each mask pack contains 1 mask, 1 filter already in the mask, and 1 replacement filter (2 filters total). We no longer include the neck strap as most of our users told us they prefer the mask without it! If you like, the neck strap is available now separately.

Great product and service!

Well if you need a mask, and you know that you do, then this is the best! It’s comfortable and has some super science that cleans itself. I’ve had mine since Sept ‘20 so I have hand washed it and it’s still doing fine. I really like the filters and that I can or a pack that’s going to last a while and it doesn’t beat up my nose or fog up my glasses. Great job!

Super useful

I didn't realize how much longer and better nanofiber was than surgical masks until reading up on it recently. Glad I only have to change out these filters about once a month!
