Common questions
What does the 36856 fit?
The ResMed S9 and AirSense 10 hypoallergenic air filter (part 36856) fits 12 ResMed models, including the AirCurve 10 CS PaceWave, AirCurve 10 S and AirCurve 10 ST. Every one is listed on this page.
How often should I replace the 36856?
Every 6 months. It works less well as the filter fills up, so it's worth doing on time.
Where can I buy the 36856 in Australia?
We track 5 Australian sellers for the 36856; the lowest listed price when we last checked was A$1.78 at Easy CPAP. Prices are re-checked daily and dated on this page.
How do I fit the 36856?
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.
