How do Austin Air purifiers work?

Austin Air HealthMate Air Purifier HM-400 Filter Assembly

• The Austin Air PERMAFILT Pre-Filter will capture visible dust and hair and should be vacuumed monthly 360 degrees around via the outside of the intake grate (no disassembly required)
• The carbon / zeolite mixture and HEPA cloth combine to create a filter that is almost 4 inches thick. This greatly extends the filter life.Austin Air guarantees this filter on a pro-rated basis for 5 years. We recommend leaving the unit on all the time, even turning it on its highest setting when you are not in the room. Therefore we recommend changing the filter after 3 years of constant use.

Cutaway of Austin Air's Construction and Engineering

• Austin Air cleaners are not made of any plastic parts. Plastics give off gases and cause problems for the chemically sensitive. That's why Austin Air cleaners have all steel construction. The sturdy steel construction of every Austin Air product guarantees that your air cleaner will last for years. Austin Air's high efficiency PSC motor draws minimal current. Even on the highest setting, it will cost only a penny an hour.

The unit only uses 100 watts of power on its highest setting.
