Common Questions About the Austin Air HealthMate Standard HM400
Does the Austin Air HealthMate have an AHAM CADR rating?
No. Austin Air does not participate in AHAM AC-1 CADR testing. Instead, the unit is rated by blower fan throughput: 75 CFM on Low, 200 CFM on Medium, and 400 CFM on High.
How often do you actually need to replace the filter?
Austin Air designs the FR400 filter to last up to 5 years under normal residential use, backed by a 5-year pro-rated manufacturer warranty. In homes with heavy smoke or extreme chemical loads, replacement every 3 to 4 years may be warranted.
How do I reset the filter indicator light?
The Austin Air HM400 is an entirely mechanical unit with no circuit boards, sensors, or indicator lights. There is no filter light to reset; track replacement by date or when airflow and odor adsorption decline.
