O2 Replaceable Filters

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 the air as well as bacteria and diseases. Based on average usage the filter can last up to 2 weeks.
