How Often Should I Replace My Hose and Other Equipment?


Whether you’re new to CPAP therapy or an old pro, keeping your equipment clean and up-to-date can be a hassle. But it’s important both for your own hygiene and the quality of your treatment.

Your CPAP machine comes with a lot of different parts. In order for the entire system to work together, each of the individual parts needs to be well-maintained. This includes not only cleaning your equipment but also replacing certain parts once they are worn out.

When to Replace Your Supplies

Different types of equipment need to be replaced at different times. For instance, your machine can last for up to five years but your hose should be changed more frequently. Let’s look at the recommended replacement schedule for each piece of equipment and when it should be replaced.

  • The hose

You should replace your CPAP hose every three months. Due to frequent use, the hose can develop small tears over time. This can lead to air leakage and compromise the quality of your treatment.

Your CPAP hose can also house bacteria growth, which is harmful to your health. CPAP users that use a humidifier should be especially careful since bacteria tend to grow in warm, damp environments. Frequent replacement, coupled with frequent washing, helps ensure that the air you breathe is nice and clean.

  • The mask and cushions

Your CPAP mask frame should be replaced every three months as well. Because you wear your mask every night, it can quickly become worn down.

Dirt and oil from your face can break down the cushion, causing a weaker seal and possible air leakage. For that reason, full face and nasal cushions should be replaced every month while nasal pillows are recommended to be replaced every two weeks. This helps keep your mask seal strong and your mask cushions sanitary.

  • The humidifier

Your humidifier chamber lasts a little longer than the hose and mask; on average, it should be replaced every six months. But you should watch out for any cracks or murky buildup in the water chamber because bacteria can begin to form in those cracks, and buildup may be a sign of mineral deposits. Using distilled water can also help lengthen the life of your humidifier chamber.

  • The headgear

You’ll want to replace your headgear every six months, for quality and comfort purposes. Over time, headgear may stretch out as the elastic is worn down, which compromises your mask seal. If you notice that your mask is no longer fitting as tightly, or you are beginning to experience air leakage, it may be time to trade your old headgear in for a new one.

  • The CPAP machine

You’ll probably be relieved to hear that your CPAP machine only needs to be replaced every five years! With proper care, you should be able to get a lot of life out of your machine before it’s time to think about getting a new one.


Nobody likes to replace their old equipment but it’s definitely worth the extra expense. Most CPAP users agree that they notice a difference in their treatment and even sleep better after replacing old supplies.

To extend the lifespan of your mask and other equipment, it’s important to take good care of it. Make sure you always thoroughly clean your device and accessories. That way your machine will function well and you can enjoy a restful night of sleep!
