How Often to Replace CPAP Supplies

Not sure how often to should replace CPAP supplies and replacement parts, such as cushions, headgears, tubing, etc.?

Look no further, as we’re here to explain the recommended replacement schedule for CPAP mask and machine parts and how to know when it’s about time to replace them.

CPAP Machine Replacement Parts

The CPAP machine consists of the device, filters, tubing, and water chamber.

1. CPAP Machine

The CPAP machine should be replaced approximately once every 5 years.

Every few years, CPAP companies release newer models of machines with updated technology and built-in algorithms, allowing for a more reliable and comfortable therapy. If your machine is working fine after 5 years and you don’t have any issues with it though, the device may be used for a few more years.

Disposable filters should be replaced twice per month, whereas reusable filters may be replaced once every 6 months.

Over time, dust, allergens, and other harmful particles builds up in the filter, so it is important to regularly replace it with a clean filter to maintain hygienic conditions for your CPAP therapy.

CPAP Hose/Tubing

CPAP tubing should be replaced once every 3 months.

Over time, your CPAP tubing may develop micro tears, making it prone to small leaks and impacting the prescribed air pressure for your therapy. Moreover, without proper and thorough cleaning, harmful bacteria, viruses, and mold may build up inside your hose. You can consider using an automated hose cleaner to reduce the risk of this happening.

Water Chamber

The CPAP water chamber should be replaced once every 3 months.

The humidifier water chamber is an optional machine part. Read more about it in our blog post: do I need a CPAP humidifier?

The water chamber becomes worn out with repetitive use. Also, mold and bacteria thrive in the humidified environment of the water chamber, so it is important to replace the humidifier to keep the chamber clean and sanitary.

CPAP Mask Replacement Parts

The CPAP mask consists of the mask frame, headgear/chinstraps, and cushions or pillows.

Mask Frame

The CPAP mask should be replaced once every 3 months.

You may notice over time that the mask doesn’t fit as snugly as it used to, or the mask frame may become bent or discolored with repetitive use - this is a sign that the frame may need replacing.

If you’re struggling with mask leaks or discomfort, you may also want to consider switching masks to a new brand or model. Take our CPAP mask finder quiz to get a personalized recommendation based on your lifestyle needs!

Headgears and Chinstraps

The headgear and chinstraps should be replaced once every 6 months.

You may notice your headgear or chinstrap losing its elasticity and becoming looser over time, causing you to over-tighten it to compensate. This over-tightening can often lead to red marks or discomfort, so it’s generally a good idea to replace it 1-2 times a year.

Mask Cushions and Nasal Pillows

The full face mask cushion should be replaced once per month, while the nasal mask cushion and nasal pillows should be replaced twice per month.

As the cushion and pillows are parts of the mask that have direct contact with your face, dust, oils, and other particles may cause them to become soft and worn out pretty easily. You may even notice that the cushion or pillow becomes discolored.

This can lead to a number of potential issues - air leaks, irritation, red marks, and so on.

Hopefully, you now have a better idea of when you should be replacing your CPAP mask and machine parts! Check out our post on CPAP HCPCS codes for more detailed information about the recommended replacement schedule.
