Austin Air Standard Pet Machine Filter

All our filters are designed to last up to 5 years under normal residential use. You can check the size of your existing filter by looking for a label on the bottom of the unit. Model HM400 indicates standard size filter. Still not sure which filter you need? Our Standard size filters measure 14.5” high. Feel like an upgrade? All standard size units are interchangeable with all standard size filters. So, if you purchased a HealthMate® and would like to upgrade to a HealthMate Plus® you can replace your old HealthMate® filter with a new HealthMate Plus® filter.

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 Pet Machine®, simply purchase a replacement Pet 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.
