O2 CANADA COMMUTER FILTER (5/PACK)

  WHILE QUANTITIES LAST. O2 Canada electrostatic filters are charged with pockets of both negative and positive ions, which attract, trap and neutralize small particles. They efficiently filter particles at 0.1 microns and larger. The highly effective O2 Canada filter traps mechanical pollutants found in pollution as well as bacteria and diseases, and based on average use the filter can last up to 2 weeks. Note: The filter goes inside your mask and needs to be changed at regular intervals dependent on usage.
