What You Need to Know About CPAP Replacement

Your CPAP mask and equipment collect dirt, oil and bacteria from your skin and nasal airways that can become a health risk when deposited back onto your skin or inhaled. It’s important that your CPAP equipment is clean in order for it to function effectively and remain sanitary for use. Just like you change personal hygiene items like your toothbrush and razor, you also need to replace your CPAP accessory equipment.

Follow our general CPAP replacement guide to maximize the comfort and health benefits of your sleeping device!


How Often Should You Replace your CPAP Mask and Supplies?

Although your medical equipment provider or insurance may keep you on schedule for your CPAP replacement, you should know when to replace your CPAP mask and accessories! You should also be aware of signs that indicate it’s time to swap out your equipment. This way, you can ensure that your CPAP therapy is safe and sanitary at all times.


If you are experiencing leaks in your mask or if your mask is damaged in any way or no longer fits properly, it’s time to replace it. Generally, your mask should be replaced every three months.

Mask Cushion and Pillows

CPAP mask cushions and nasal pillows are designed to provide comfort as they rest against your face and seal the pressurized air pathway. The material breaks down as it is exposed to the oil and bacteria on your skin, leading to air leaks, irritation and discomfort. You should replace your cushions and pillows as often as two times per month. Full face cushions can be replaced once a month. Cushions that need to be replaced may change color or become stiff or cracked.


As your headgear repeatedly stretches, it may no longer accommodate your head shape and lose its seal. If your headgear is discolored or no longer holds a secure seal, it’s time for a replacement. Your headgear should be replaced every six months.


Just like your headgear, the chinstrap may stretch and weaken over time. Replace your chinstrap every six months.


CPAP filters are responsible for making sure that the air that is delivered through your machine is clean and free of allergens or other irritants. Similar to a car or vacuum filter, your CPAP filter will become clogged with build-up. A clogged filter makes your machine less effective and unsanitary, so it’s crucial that you replace it every two weeks.


Your CPAP tubing, which provides the passage for pressurized air to travel to your mouth, can collect bacteria and develop cracks and tears with frequent use. The tubing should be replaced every three months. If your tubing is no longer clear or if you notice small tears, be sure to replace it immediately!

Humidifier Water Chamber

The water chamber is the removable container that holds the water in your CPAP machine’s humidifier. The humidifier warms and moistens the air you’re breathing to prevent you from having a dry nose and throat. It also helps you keep your mouth closed while you’re sleeping. To make sure your humidifier functions properly, replace the water chamber every six months.

CPAP Machine

The typical lifespan of a CPAP device is five to seven years. You may want to replace it anywhere between three and five years as technology improves. If your CPAP machine stops working, contact your provider immediately!
