The Health Mate™ has a True Medical HEPA filter surrounded by a carbon/zeolite mixture which absorbs odors and gases. With 60 sq. ft. of medical HEPA, certified to remove 99.97 percent of airborne particles 0.3 microns and larger, once particles are captured they are permanently removed from the air for easier breathing. The Health Mate™ contains 13-15 pounds of granular carbon and zeolite for the adsorption of odors, gasses and chemicals for a healthier indoor environment. It comes with wheels already attached for easy use and portability. The powerful centrifugal fan maximizes air output while minimizing energy usage for pulling air through the filters, which means lower cost and faster room air purification (for rooms up to 1500 sq. ft. with normal ceiling heights). Available in white, sandstone, black and silver - so it blends better into your room's decor.
