These disposable standard filters fit ResMed's previous CPAP/BiPAP generation — the S9, AirSense 10, and AirCurve 10. They protect the inner workings of your device from dust and large particles, and should be replaced regularly to maintain proper airflow.
Compatible with three ResMed generations:
- ResMed S9 (older generation, pre-2014)
- ResMed AirSense 10 CPAP
- ResMed AirCurve 10 BiPAP
Not interchangeable with the AirSense 11 / AirCurve 11 — newer devices use a different filter format.
ResMed's standard guidance is to replace these filters approximately every 6 months under normal household conditions. Replace sooner if the filter is visibly soiled or if you live in a dusty environment.
Call 1-800-775-0942 with your ResMed model — we'll confirm whether you need this filter or the newer AirSense 11 / AirCurve 11 version.
