3What’s inside count
Austin Air Allergy Machine 4-stage filtration is excellent for people suffering from asthma and allergies. The first stage filtration consists of outer mesh filter and inner pre-filter that would trap large particles such as pet hair. The 2-stage medium filter would, of course, capture medium size particles while the 3-stage HEPA filter would trap even smaller airborne particles. Finally, Allergy Machine High-Efficiency Gas Absorption (HEGA) filter would trap odor and gas-based allergens that often linked to household contaminants.Keep it down
