Common questions
- Which filter fits the ResMed AirCurve 10 CS PaceWave?
- The ResMed AirCurve 10 CS PaceWave takes the ResMed S9 and AirSense 10 standard air filter (part 36851). Compatible filters made to the same specification also fit.
- How often should I replace the filter in my ResMed AirCurve 10 CS PaceWave?

- Where can I buy the 36851 in Australia?

- How do I fit the 36851 in a ResMed AirCurve 10 CS PaceWave?
- No tools, a few minutes: 4 steps, listed on this page with the replacement video where the maker has one.
- What happens if I don't change it?
- A blocked filter restricts the air the machine draws in, and a torn one lets dust and pollen through; the manual says when to replace it.
- Is there anything to reset afterwards?
- No reset in ResMed's guide. If your care provider turned on replacement reminders, the machine shows them on screen; ResMed's guide does not say the machine detects a new part.
