Aftermarket Group Respironics Foam Filter M Series
These are the original Philips Respironics (OEM) brand foam filters for the System One, M-Series, and SleepEasy models of CPAP and BiPAP machines. These are the reusable foam filters that are required when operating the machine.
How Often Should I Clean the Filters
Clean the gray foam filter at least once a week and replace it with a new one every six months.
Wash the gray foam filter in warm water with a mild detergent. Rinse thoroughly to remove all detergent residue. Never install a wet filter into the device; it should be completely dry before reinstalling it. If the foam filter is torn or feels thin, replace it.
Caution
Dirty inlet filters may cause high operating temperatures that may affect device performance. Regularly examine the inlet filters as needed for integrity and cleanliness.
