Use a CPAP cleaning machine to keep your device’s interior dust-free and working efficiently.

Make sure the filter is properly aligned to avoid any air bypass or leaks.
Pair your filter maintenance with hose cleaning using a brush set to keep airflow clear.
Using distilled water in your humidifier can help reduce airborne particles reaching the filter.
Regular filter changes also help protect your CPAP motor from dust and extend the device’s life.

Clean Filters, Better Sleep

These disposable filters are made to fit snugly into your AirSense 10, S9, AirCurve, or AirStart device. They help reduce dust, pollen, and other particles from entering the airflow so your machine can deliver cleaner air—and your therapy stays on track night after night.

Sized Right for ResMed Machines

No trimming or forcing into place—these filters are cut to match your ResMed device exactly. That tight fit helps block fine particles from slipping through and affecting airflow. It’s a simple swap that supports better breathing and extends the performance of your CPAP machine.

Helps Protect Your Airways

Filters don’t just keep the machine clean—they also protect your lungs. Swapping them regularly helps reduce exposure to airborne irritants like pet dander or smoke. Clean filters mean fewer chances for particles to circulate while you sleep, especially important if you have allergies or sensitive airways.

Easy Replacement Schedule

Each pack contains three filters—enough for around one month of regular use if changed every two weeks. If you have pets, smoke indoors, or notice discoloration sooner, it’s a good idea to replace them more often. It’s a small step that can make a noticeable difference.

Supports Your Machine’s Lifespan

A dirty filter can strain your CPAP device, reducing airflow and making it work harder than necessary. Replacing filters regularly helps the machine stay efficient and prevents buildup that could interfere with long-term performance.
