CPAP Filters & Health Device Replacements

CPAP machines use two types of filters: disposable white ultra-fine filters and reusable gray foam/pollen filters. The disposable filter captures fine particles (dust, mold spores) and must be replaced regularly. The reusable foam filter catches larger debris and should be washed weekly.

For ResMed AirSense 10/11, the standard filter is a white hypoallergenic disposable. For Philips DreamStation, it uses a blue reusable pollen filter plus a white disposable ultra-fine filter. These are NOT interchangeable between brands — ResMed filters do not fit Philips machines and vice versa.

Insurance and Medicare often cover CPAP supplies including filters. Check with your DME (Durable Medical Equipment) provider. Even without coverage, compatible CPAP filters are inexpensive enough that replacing on schedule is not the costly part of CPAP therapy.
