CPAP Masks and Accessories Replacement Schedule

The bottom line is that replacement frequency of CPAP supplies differs by person, care and product. Your needs are not necessarily related to what your insurance company will provide for you. Good care of the equipment and accessories will certainly extend their life, but it is not purely a matter of cleaning, as facial oils and general usage will also impact supplies. Even if some of the equipment looks clean it still may be worn down from frequent usage which can lead to CPAP side effects. Some product manufacturers recommend more frequent replacement of key CPAP supplies, particularly of pillows and cushions. You will need to proactively manage your condition based on product manufacturer recommendations, doctors' guidance and how it feels to you.

Insurance companies recognize that providing for replacement of new CPAP supplies frequently will keep your equipment working properly and reduce significant health conditions from untreated use - see Is Sleep Apnea Fatal? to understand the most dire ramifications of non-compliant treatment. Though every insurance company is different, they typically follow the Medicare reimbursement schedule. Below is the general schedule from Medicare.
