The Airpura C600 is a specialty air purifier designed for removing chemicals and gases from the indoor air. We recommend the Airpura C600 for indoor environments polluted by high concentrations of chemical or gas vapors produced from fire or smoke, second hand smoke, perfumes, cleaning products, cooking odors and off-gassing of toxic gases. The Airpura C600 is also a great choice for use in MCS situations. Please keep in mind this machine is not for sub-micron particle removal. If you are in need of an all-purpose air purifier that will remove a substantial amount of chemicals, gases and odors, as well as offer excellent airborne particle removal, we recommend the Airpura R600.
