All replacement filters have up to a 5 year life expectancy
The Austin Air HealthMate Plus® Filter has a true medical grade HEPA (High Efficiency Particulate Arresting) filter surrounded by a blend of potassium iodide impregnated carbon/zeolite mixture. This additive, along with the activated carbon and zeolite, delivers greater capacity for the filtration of chemicals and gases including Volatile Organic Compounds (VOCs). The HEPA filters 99.97% of all particles down to 0.3 microns in size. Consequently, this combination of medias provide improved relief in highly contaminated air spaces for those who are severely chemically sensitive.
