All Austin Air filters are designed to last up to 5 years under normal residential use. This listing is for replacement filters for all junior size models. You can check the size of your existing filter by looking for a label on the bottom of the unit. Model HM200 indicates a junior size filter. Still not sure which filter you need? Junior size filters measure 11.5” high.
Feel like an upgrade? All junior size units are interchangeable with all junior size filters. So, if you purchased a HealthMate Junior® and would like to upgrade to a HealthMate Junior Plus® you can replace your old HealthMate Junior® filter with a new HealthMate Junior Plus® filter.
