How Often Should I Replace My CPAP Supplies?
Filters, tubing, and mask cushions are the items that most often need replacing. How long each one lasts depends on your home environment, how often you clean it, and how you clean it. We recommend inspecting these items regularly and replacing them as needed rather than waiting for a fixed date, since wear varies from person to person. For a full breakdown by item, see our dedicated Replacement Schedule page.
CPAP Filters
CPAP filters help clean the air your machine draws in before it reaches you. In general, replace filters every two to four weeks. If you live with smokers or pets, you'll likely need to replace filters more often, since both introduce more particulates into your home's air.
CPAP Tubing
CPAP tubing should be replaced every 6 to 12 months, depending on its condition. Inspect tubing periodically for cracks, holes, or stiffness, which can affect airflow and pressure delivery even before the tubing looks obviously worn.
CPAP Mask Cushions
CPAP mask cushions are one of the most important factors in successful therapy, since they maintain the seal that keeps your prescribed pressure consistent and prevents leaks. Skin oils and regular use both affect how long a cushion lasts, and a cushion doesn't need to look visibly broken to be underperforming — over time, cushions can lose their seal well before any obvious damage appears. Inspect your cushion regularly and replace it as needed rather than waiting for a visible problem.
CPAP Headgear
Headgear also wears out over time, typically losing elasticity from regular washing and nightly use before it shows obvious damage. If your headgear no longer holds a snug fit even at maximum adjustment, or feels noticeably looser than when it was new, it's time to replace it — usually every 6 months or so with regular use, though this varies based on your washing routine and how often you wear your mask.
