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.

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!
