M-Series CPAP Filters & Replacement Supplies

Clean, consistent airflow starts with a fresh filter. The M-Series collection centers on disposable ultrafine CPAP filters from Sunset Healthcare, engineered to trap the fine airborne particles, dust, and allergens that would otherwise circulate through your machine and into your airway each night. For anyone on sleep therapy, staying current on filter changes is one of the simplest ways to protect both breathing comfort and the working life of the equipment.

This collection includes the Sunset Healthcare M-Series Ultrafine CPAP Filter (CF1007-1) and its companion CF1007-2, both disposable and designed to seat securely in compatible M-Series CPAP units. Ultrafine filters are the finer of the two filtration stages most machines use — they capture microscopic particulates rather than just the larger debris handled by reusable foam filters, which makes them especially valuable for users sensitive to allergens or pet dander.

How often should you replace them? Because these are disposable, most users swap ultrafine filters roughly every two to four weeks, sooner if you live in a dusty environment, have pets, or notice visible discoloration. They are not meant to be washed and reused — once soiled, a fresh filter restores proper airflow and filtration. Keeping a supply on hand means you are never tempted to stretch a dirty filter past its useful life.

Always confirm the filter matches your specific machine model before ordering, as CPAP filters are sized to particular device series. If your equipment belongs to a different family, browse our related supplies for the 10 Series, 100 Series, or 200 Series to find the correct replacement parts for your setup.
