To keep your CPAP supplies clean and working effectively over the long term, you should regularly inspect your accessories and set an equipment replacement schedule. In this article, CPAP Discount Warehouse will answer the question of When to replace CPAP supplies and explain why each component should be replaced before it negatively affects your therapy and sleep.

Why Do CPAP Masks Need to Be Replaced?

A CPAP mask is placed against the skin and channels pressurized air from the machine, so it is exposed to degradation from skin oils and buildup. Components like the headgear and tubing can be weakened by regular stretching and bending.

You should clean your CPAP gear; however, after a while, cleaning only goes so far. For comfortable and effective performance, replace equipment according to the manufacturer’s recommended schedule. Even if your CPAP mask looks good, it may still cause problems such as increased leaks, bacterial growth, and skin irritation. CPAP mask leaks are a common issue they’re uncomfortable and can lower the delivered pressure, reducing the effectiveness of your therapy.

When to replace CPAP Mask Parts?

It depends on your CPAP mask’s manufacturer and the type of CPAP mask, as each has its own timeline for replacing parts such as the frame, cushion, headgear, or tubing.

Insurance providers with CPAP coverage also have their own schedules for how often you should replace CPAP accessories. Because these schedules vary, be sure to double-check your policy before following our timeline.

In addition to following a replacement schedule, inspect your mask equipment during cleaning and replace any items that are visibly worn or damaged.

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.
