# Austin Air Bedroom Machine Replacement Filter FR402B, White

**Replacement Filter for the Austin Air Bedroom Machine with Pre-Filter**

The **Austin Air Bedroom Machine** is specially designed to help individuals with sleep-related concerns by removing airborne pollutants from the bedroom environment. Clinical trials confirm its effectiveness in filtering out harmful airborne contaminants, promoting cleaner air and better sleep.

All standard-size Austin Air units are interchangeable with standard-size filters. If you own a HealthMate and wish to upgrade to the Bedroom Machine, simply purchase this replacement filter.

⚠ Before ordering, confirm the correct size and type to avoid restocking fees on incorrect returns. Check the label on the underside of your unit—Model HM400 indicates a standard-size filter.

✅ Stage 1 – Large Particle Pre-Filter – Captures visible particles such as dust, hair, and pet dander.
