Care

The NanoFit Mask should be stored in a cool, dry environment. It should not exposed to direct sunlight or extreme heat. Replaceable filters should be kept in their original resealable package until ready for use.
We do not recommend washing the NanoFit Mask skin often, as it is protected by Polygiene’s ViralOff® technology. For best performance and sustainability, wash less and only when needed. We recommend either hand washing with water only or washing on a delicate cycle with no detergent. Always remove the filter before washing. Air dry only. The neck strap may be wiped down with a disinfectant wipe.
- Before putting on a mask, clean your hands with an alcohol-based hand rub or soap and water.
- Place ear loops around your ears, covering both your mouth and nose with the mask. Make sure there are no gaps between your face and the mask.
- For the NanoFit Mask, press the adjustable nosepiece snugly against the bridge of your nose to ensure a close fit. Add the neck strap if you desire.
- The WHO recommends not touching a mask while using it. The NanoFit Mask is protected by an antimicrobial coating which decreases the chance of contamination on the mask.
- To remove the mask: remove the ear loops from behind the ears, and the neck strap if you are using it. Do not touch the internal nano filter. Clean your hands with alcohol-based hand rub or soap and water.
