Product Description

Healthmate HM405 is recognized as a leader in air purification for quality construction and is often a recommendation by many Allergists. This item is intended for those with severe allergies and asthma. It provides identical particle removal capacity and efficiency. The allergy machine removes a wide variety of contaminants, including dust, pollen, dander, odors, chemical vapors and more. However, instead of 15 lbs of granular carbon, a lightweight military-grade carbon cloth is used to create HEGA filtration - High Efficiency Gas Absorption. The carbon cloth does not release carbon dust when air passes through it, allowing it to be placed after the True HEPA filter. This enables the carbon to be more efficient as the complete surface area is available solely for gas removal.   Available at AppliancesConnection

The High Efficiency Gas Absorption (HEGA) carbon cloth used in this air purifier was developed by the British military to protect against chemical warfare and is proven to provide relief for those suffering from allergy and asthma.
