The HealthMate Standard can clean the air in an average bedroom size space up to 13 time per hour. The factory says they can effectively clean open areas up to 1500 square feet. However we honestly feel that effective cleaning in open areas of 1000 square feet is more accurate.

However, the dust and allergen removal ability will continue for up to 5 years before replacement will be necessary.

Special Note

The only difference between the HM-400 Austin Air HealthMate Standard HEPA air purifier and the HM450 HealthMate Plus model. The HM450 models have Potassium Iodide added into the 15 pound carbon-zeolite blend. This aids in removing more out gassing chemicals from new carpeting, pesticides, various household furnishings and materials. Which can cause allergy, asthma and other respiratory problems. The difference and increase in price for the HM450 HealthMate Plus air purifiers model unit is for the filter drum. So the Drum in the Hm450 unit adds a cost of $110.00.
