Austin Air units have all steel construction with baked on powder coat finish. They are tough and need virtually no maintenance. A pre-filter removes large particulate and an integrated HEPA/activated carbon-zeolite filter removes particles down to 0.3 microns as well as gases and odors. Austin Air models have 3 speeds and no fancy features which make them very dependable. The main HEPA/carbon filter can last for up to five years depending on what it's filtering. They remove dust, dust mites, pollens, mold spores, pet dander, smoke particles, and odors.
All Austin Air models that ClearFlite offers are available in 220volt and are customized with the proper plug for the country in which the units will be used. Customers can choose the plug desired.
The standard units (HM400 and HM200) remove particles and odors, but the Plus models (HM450 and HM250) do a significantly better job removing odors, even formaldehyde.
