The ResMed S9 filter cover is a small snap on cap that secures the air filter on the back of S9 series machines, and CPAP Supplies Canada keeps it in stock for owners across Canada. It is the piece that clips over the filter slot, holding the filter square against the intake so unfiltered air cannot slip around the edges.
This cover is designed for the ResMed S9 series, including S9 CPAP and AutoSet machines and S9 VPAP BiLevel units. ResMed lists the part as 36859. It is a replacement for a cover that has cracked, warped, or gone missing.
Behind the cover sits the intake filter. Check it monthly and replace disposable filters as they discolour, usually about every 30 days, so the cover and filter work together to keep your air clean.
Does a filter come with the cover?
The cover is sold on its own. Order S9 filters separately if you also need replacements.
Will it fit an AirSense 10?
No. This cap is shaped for the S9 housing. The AirSense 10 uses a different filter door.
CPAP Supplies Canada ships the S9 filter cover across Canada, and this accessory does not require a prescription.
