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 airflow, 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.
Due to Covid-19, we are no longer able to accept returned replacement filters. When ordering your replacement filter, please ensure you have selected the correct size and type, before confirming your order.
You can check the size of your existing filter by looking for a label on the underside. Model HM400 indicates a standard size filter.
