Common Questions About the Austin Air FR400 HealthMate Replacement Filter
Will this filter fit the Austin Air HealthMate HM400?
Yes. The FR400 is the official standard replacement filter engineered specifically for the full-sized Austin Air HealthMate HM400 and HM450 units.
Can this replacement filter be washed?
No. Never wash True HEPA or carbon filters in water. Moisture destroys the micro-glass HEPA structure and deactivates the carbon pore matrix.
How do I know it is time to replace the filter?
Because Austin Air units use analog mechanical controls without electronics or reset lights, monitor filter age (typically 4 to 5 years) or replace if airflow noticeably diminishes or stale odors break through.
