Get the most out of your O2 Nano Mask with a stash of replacement filters. Coming in a pack of three, each filter helps provide unwavering protection from PM2.5 particles thanks to a three-layer nanofiltration membrane, smaller than many viruses, including influenza.

Fully recyclable, the O2 Nano Filters help you be as good to the environment as you are to your lungs.

It's best to order filters of the same size as your O2 Nano Mask.

  • Includes 3 filters
  • Each filter should last up to 60 hours or total wearing time
