The filter in an Austin Air Healhtmate PLUS is designed to last for 5-years. This is made possible through the use of two pre-filters.

Stage 1: The large particle pre-filter removes dust, hair and pet dander.

Stage 2: The medium particle pre-filter removes mold, spores, and pollen.

Stage 3: The specially blended carbon reduces the level of thousands of gasses, odors, and chemicals. The Healthmate PLUS is specially optimized with the addition of pottasium iodide to for enhanced chemical reduction and is designed for people that are chemically sensitive.

Stage 4: The true medical grade HEPA filter removes bacteria and viruses.
