Filter for Austin Air - Allergy/HEGA Filter for Allergy Machine - Made in the USA!

Filter designed to last 5 years!

Replacement filter for the Austin Air Allergy Machine® with Pre-Filter. 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.

When ordering your replacement filter, please ensure you have selected the correct size and type, before confirming your order as there may be a restocking fee for returning filters that are ordered incorrectly.
