Replacement filter for the Austin Air HealthMate Plus®. The Austin Air HealthMate Plus® removes a wide range of gases, chemicals, VOC’s and formaldehyde. This broad-spectrum adsorption makes it the best choice for people exposed to smoke from wildfires and people living close to busy highways.

All standard size units are interchangeable with all standard size filters. So, if you purchased a standard size HealthMate® and would like to upgrade to a standard size HealthMate Plus®, simply purchase a replacement HealthMate Plus® filter. This also applies for all of the Junior models.
