ResMed AirSense 11 CPAP Filters – Standard

These standard ResMed filters fit AirSense 11 (AutoSet, Elite, AutoSet for Her) and AirCurve 11 devices. They are not compatible with AirSense 10, AirCurve 10 or older S9 models, which use a different format. Verify your model before purchase.

The manufacturer states every 3 to 6 months. We recommend replacement every 1 to 3 months for optimal hygiene. With pets, dust or allergies at home, go for monthly replacement. A clogged filter restricts airflow and wears out the motor.

The standard filter offered here captures dust, pet hair and common everyday particles. The hypoallergenic filter offers finer filtration (pollen, spores, ultra-fine particles) recommended for patients with asthma or allergies.

Open the filter compartment at the back of your AirSense 11. Remove the used filter and discard it. Insert the new filter with the blue side facing outward, then close. The operation takes under a minute, no tools or disassembly required.

The filter protects your device and your airways. Without a filter, dust enters the turbine and clogs it, shortening your CPAP lifespan. For you, it ensures clean air, free from particles that irritate your bronchi.

Inspect the filter once a month. If it looks grey, yellowed or shows trapped dust, replace it. A louder CPAP or weaker perceived airflow are other signs. Never wash a standard filter: it is single use only.

Several pack options are available depending on your replacement schedule. The 2-pack covers about 6 months. The 5-pack or 10-pack is more economical for users who change their filter monthly. Choose the option matching your routine.
