Quick answer: These are genuine ResMed standard disposable air filters for the Air11 series — the newer AirSense 11 and AirCurve 11 devices. The standard filter is the single-layer filter that traps dust and airborne particles before room air enters the device — protecting both the air you breathe and the machine. Important: Air11 filters are a different shape from Air10 filters and are not interchangeable. Available in a range of pack sizes, from single filters up to a 50-pack. Device not included.

About this filter
Your AirSense 11 / AirCurve 11 draws in room air, and the standard filter is the first line of defense — trapping dust and airborne particles before they reach the airflow or the device. It's the everyday filter that ships with the machine.
ResMed offers two filter types for the Air11: this standard filter (single-layer, captures typical dust and particles), and a hypoallergenic filter (finer, multi-layer, captures smaller particles). The standard filter is the routine choice for most users.
Filters load up with debris over time and become less effective, so they're replaced on a schedule (more often in dusty homes or with pets). It's a disposable filter — replaced, not washed. Buying a larger pack brings the per-filter cost down and means you always have a replacement on hand, which is why the 50-pack is popular with regular users and providers alike.
Crucially, Air11 filters are not the same as Air10 filters. The AirSense 11 uses a redesigned filter that differs in shape from the AirSense 10 version — so if you've upgraded to an Air11, your old Air10 filters won't fit. Always match the filter to your exact device.

Air11 vs Air10 — check your device
The AirSense 11 / AirCurve 11 filters are shaped differently from the AirSense 10 / AirCurve 10 filters and are not interchangeable. Before ordering, confirm your device is the 11 series, not the 10. The model is printed on the device — or call us at (718) 735-3400 and we'll confirm which filter you need.
Standard or hypoallergenic — which do I need?
Both fit the Air11; the difference is filtration level:
- Standard filter (this) — single-layer; captures typical dust and particles. The everyday option.
- Hypoallergenic filter — finer, multi-layer; captures smaller particles including fine dust and pollen.
Most users use the standard filter; the hypoallergenic is chosen for finer filtration (pets, dust, pollen sensitivity). Both are disposable and replaced on schedule.
How often should I replace it?
Replace the standard filter on the schedule in your device's user guide — commonly around every month or so, and sooner if it looks dirty, discoloured, or clogged, or if your home is dusty or has pets. It's a disposable filter — replace it, don't wash it.
