ResMed AirSense 11 Filter Door Replacement

The ResMed AirSense 11 Filter Door is the genuine replacement for the small door at the back of your machine that covers the air filter recess and holds the filter in place. It's a common part to replace — the door can be misplaced during a filter change, or the small hinge can break with repeated opening.

Key Features

• Genuine ResMed part — made to fit the AirSense 11 filter recess exactly, so it sits flush and closes properly.
• Holds your filter in place — keeps the air filter seated correctly over the machine's air intake.
• Tool-free — opens and closes by hand whenever you change the filter.
• Australian stock — shipped from our North Lakes, QLD warehouse.

Filter Door or Filter? They're Different

This is the door — the reusable cover, not the filter underneath it. If you're after the disposable filter itself, you need the AirSense 11 standard filter, or browse all CPAP filters. ResMed recommends replacing the filter roughly monthly — sooner if it looks dirty.

Not the SD Card Door

The AirSense 11 has two small doors. This one covers the air filter. If you're after the door over the SD card slot, that's the separate AirSense 11 SD card door.

Who Is This For?

ResMed AirSense 11 owners who've lost or broken their filter door. This part fits the AirSense 11 only — the AirSense 10 uses a different filter cover design.
