Why respirators need antimicrobial

Germs are present in droplets and airborne suspended particulate matter → the greater the humidity and the pollution, the greater the infection risk.


  • Particulate matter filters, even those that meet N95 and N99 standards, can filter most bacteria and some viruses.
  • However, trapped pathogens are still alive on the mask and can still go through.
  • Through natural respiratory action and handling (removing, storing, wearing), this poses a greater infection risk.
  • Applying a disinfecting technology would alleviate this risk.

Why existing antimicrobial technologies pose a greater risk

Some premium masks currently use filters that are treated with silver to actively absorb and destroy bacteria, but they aren’t effective enough against viruses.


  • Silver-based antimicrobial technologies, and similar ones using zinc, copper, etc, are reprotoxic – toxic to humans’ reproductive systems and foetuses, and skin sensitizing.
  • Many silver-based antimicrobials are accordingly banned in Europe, and increasing scrutiny is underway on similar technologies by global regulators.
