Alliance Oxygen Concentrator Filters & Compatible Supplies

If you're keeping a Healthdyne Alliance oxygen concentrator running smoothly, the filters you use aren't optional maintenance — they're what protects both the machine and the air your patient breathes. This collection focuses on replacement intake filtration compatible with the Alliance and related concentrator platforms.

At the center of it is the Sunset Healthcare Intake Bacteria Filter (BF2222), built with standard 22 mm fittings and cross-compatible with several common units — the Healthdyne Alliance and BX5000, the Respironics Millennium, and the CHAD TotalO2. That wide fit matters: many home care providers and DME suppliers stock a mix of concentrators, and a single filter that spans multiple models simplifies ordering and inventory.

An intake bacteria filter does two jobs at once. It traps airborne particulates and microorganisms before they reach the compressor and sieve beds, extending the concentrator's service life, and it helps ensure the oxygen delivered downstream stays clean. Because these filters are consumables, they're replaced on a regular schedule rather than run to failure — check the concentrator's manufacturer guidance, but many programs swap intake filters on a routine interval to stay ahead of clogging and reduced airflow.

When replacing yours, confirm the fitting size (22 mm here) and that your model appears on the compatibility list above so airflow and seal are correct.
