Exceleron CPAP & BiPAP Filters

If you run a CPAP or BiPAP machine, the filter is the small part that does a big job: keeping dust, pollen, and airborne particles out of the air you breathe all night. Exceleron makes disposable replacement filters engineered to fit the most common sleep therapy machines — ResMed, Philips Respironics, and Fisher & Paykel — so you can keep your device running clean without hunting for the exact OEM part.

Which filter you need comes down to your machine model. For ResMed users, the Felt Pollen Filter for the S9 (pack of 2) and the Ultra Fine Blue/White Filter for the S8 cover two generations of popular platforms. Philips Respironics owners can choose the Ultrafine Filter for System One or the Ultra Fine Filter for the RemStar Legacy, while Fisher & Paykel HC230, HC240, and HC600 series machines are supported by the matching Ultra Fine Filter made for those humidified units.

There are two filter jobs to keep straight. Coarse or reusable pollen filters trap larger particles like dust and pet dander and can often be rinsed between changes. The ultra-fine (sometimes called "ultra-white") filters catch the smallest particulates and are strictly disposable — never wash them, since that damages the fine media and reduces protection. Most people replace ultra-fine filters roughly every two weeks to a month, or sooner if you have allergies, pets, or a dusty bedroom. A clogged or graying filter is your cue to swap it.

Clean filters protect the internal motor and blower, keep airflow consistent, and reduce the irritants reaching your airway — small maintenance that extends the life of an expensive machine. Buying in disposable multi-packs means you always have a fresh one on hand.
