O2 Mask Commuter Filters - 3 Pack
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: *These are the filters only. You must purchase the O2 Mask separately.
