A dual mode compressed air purifier is presented having a cart for transportation purposes and including a chemical medium purifier with a regenerable filter cartridge. A first purification mode removes water, carbon dioxide, hydrocarbons and other impurities from compressed air which is then available for supplied air respirators of workers in hazardous environments. In the second or regeneration mode compressed air is heated and then delivered to the chemical medium purifier whereby impurities removed by the medium during purification are collected and expelled by the hot air and are then exhausted from the dual mode air purifier. The cooling cycle of the regeneration mode returns the chemical medium purifier to an ambient temperature after which purifying can begin again.
