Replacement filter for the HealthMate™ Air Cleaner (Austin Air HM400). It is constructed using a true medical High Efficiency Particulate Arresting (HEPA) filter surrounded by a carbon/zeolite mixture capable of removing the tiniest of particles and absorbing odors and gases. The Austin Air HealthMate HM400 Filter uses the HEPA to remove up to 99.97% of all particles down to 0.3 microns in size and 95% down to 0.1 micron.
Choose white (K292) or black (53668A) or depending on the color of your HealthMate. These filters should be replaced approximately every 5 years.
