Created for those allergy and asthma sufferers who struggle to find relief, the Allergy MachineTM is the only air cleaner on the market to incorporate HEGA filtration. The Allergy MachineTM features High Efficiency Gas Absorption, removing contaminants out of the air before they get a chance to irritate and trigger your asthma or allergies. For an air cleaner to be effective, it must remove sub-micron particles, noxious gases and chemicals from the air without creating by-products such as ozone. In every Austin Air cleaner, you'll find True Medical Grade HEPA and Activated Carbon, the only trusted filter technology used in hospitals and operating rooms. Manufactured in the United States, Austin Air further minimizes its energy consumption when processing, packaging and transporting products to you. Austin Air is committed to operating within policies that lessen our carbon footprint and promote clean air for generations to come. Each Austin Air cleaner must meet stringent government and independent third-party testing standards, with tests designed to protect you by ensuring the products you buy work as claimed. Austin Air takes no shortcuts and never submits its products for private testing to guarantee a desired result.
