When to replace CPAP supplies?
Over time, your CPAP mask frame and headgear can lose their fit and flexibility, affecting comfort, seal, and overall therapy performance. Most manufacturers, including ResMed and Fisher & Paykel, recommend replacing the frame every 3 months and headgear every 6 months. Ignoring these timelines may lead to air leaks, poor sleep, and reduced effectiveness. At CPAP Discount Warehouse, we help you stay on schedule. In this post, we’ll answer the common question When to replace CPAP supplies and explain why timely replacement of your mask parts is essential for effective therap.

When to replace CPAP Mask Parts?

CPAP mask parts wear out over time due to nightly use, facial oils, cleaning agents, and environmental exposure. Replacing them on a regular schedule helps maintain therapy effectiveness, comfort, and hygiene. Most manufacturers and insurance providers follow a standardized replacement cycle.

How often to replace CPAP mask cushion?

For example, mask cushions adhere to the face every night and can quickly accumulate dirt, grease, and bacteria. Without proper care, they can deteriorate, causing leaks and discomfort, and even skin irritation.

The frequency of mask cushion replacement depends on the type of CPAP mask. Silicone cushions should be replaced every 6 months, while memory foam cushions should be replaced every month.

How often to replace CPAP Mask Frame?

A CPAP mask frame should typically be replaced every 6 to 12 months. The exact timeframe can vary depending on the material and how well it's maintained. Older models with plastic frames may last longer, but newer frames made of silicone can harden over time and need more frequent replacement. 

How often to replace CPAP Mask Headgear?

Replace every 6 months. The Headgear and chin strap stretch over time and lose elasticity. Although it may be tempting to tighten the Headgear and continue using the mask, the loss of elasticity affects the fit of the mask and can lead to leaks or uncomfortable pressure points.

Signs that replacement is necessary: the tube shows signs of wear, such as cracks or tears.
Replacement: every 12 months.

How often to change filter on CPAP machine?

With regular use, air filters collect dirt and dust, which can lead to clogging, hygiene issues, and even allergies if they are not replaced as needed. Although it is recommended to replace them every 2 months, users working in dusty conditions should check them frequently to monitor their cleanliness.

How often to change CPAP water chamber?

ResMed recommends replacing the humidifier water chamber every six months. If you have a valid prescription for CPAP, your health insurance company may cover the replacement costs.
