Replacement filter for the Austin Air Allergy Machine®. The Austin Air Allergy Machine® was developed specifically for people with asthma and allergies. Its unique design increases air flow, filtering allergens from the air immediately. In clinical trials the Austin Air Allergy Machine® was shown to dramatically reduce hospital visits for young asthmatic children.
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 the Allergy Machine®, simply purchase a replacement Allergy Machine® filter.
You can check the size of your existing filter by looking for a label on the underside. Model HM400 indicates standard size filter.
