When Should You Change Your CPAP Equipment and Supplies?


If you have a CPAP machine you need to change your CPAP supplies including your mask regularly. Otherwise, you’ll start to notice that you’re no longer getting a good night’s sleep. And then your health will suffer. You’ll feel tired during the day and you may start to wonder if your CPAP machine is even working properly.

The good news is that it’s very easy to replace your CPAP supplies. How often you need to replace CPAP supplies all comes down to how well you care for your equipment, how often you use it and the type of equipment you have.

Here are our guidelines for changing your CPAP supplies including mask and machine:

When Should You Change Your CPAP Mask?

There are a few signs that your CPAP mask is due for a change. The main indicator is if you notice different results in your CPAP therapy.

If you think your CPAP mask isn’t working as well check the seal. You may have noticed when you first got your mask that the seal was clean and strong. Over time it may discolour and become weak. That’s because the natural oils from your skin build up and cause the seal to lose its effectiveness. If your seal doesn’t look as good as it used to, it’s time to change your mask.

Another sign that it’s time to change your mask is if you wake up with a dry mouth. A dry mouth means something’s not right with your CPAP mask. That’s because if air is leaking from the mask it changes the air pressure and your mouth opens to compensate.

In general, it’s best to change your mask every 6 months to avoid these problems occurring in the first place. The time to get a new CPAP mask varies for each person but we recommend changing your mask every 6 months. You’ll start to notice your CPAP therapy improve with a new mask.

When Do You Need To Replace Your CPAP Cushions?

Your CPAP cushion is the soft part of the mask that actually touches your face. You need to replace this cushion regularly as it becomes worn down over time. Like all components of your CPAP machine, a worn down cushion is going to affect your CPAP therapy.

The life of your CPAP cushion depends on how often you use your machine, skin oils, how often you clean it, direct sunlight and other variables. If you have pets or small children, they may like to play with these interesting little cushions.

For hygienic reasons as well as general wear and tear, we recommend you replace CPAP cushions monthly.

When Do You Need New CPAP Headgear?

Your CPAP headgear is the elastic component that helps secure your mask to your face to prevent air leaking out. So, it’s really important to ensure you get the right air pressure prescribed to you. If the elastic loses stretch it won’t fit well anymore. And if your mask feels lose due to weak elastic, you’ll start to tighten it. Over time the less effective the elastic is and the more you tighten, the more uncomfortable wearing your mask will become. You may even start to notice slight indents on your face due to your mask not fitting correctly.

Also, sweat and moisture weaken elastic and cause bacteria to build up. So there’s also important hygiene reasons to consider in changing your mask regularly. General guidelines recommend changing CPAP headgear every 6 months.

When Should You Replace Your CPAP Mask Tubing?

If you notice small holes, tears dirt or discolouration of your CPAP machine tube it’s time for a replacement. Even minor damage to your tubing will affect the air pressure you receive. And that means you won’t be receiving the correct CPAP therapy that was prescribed to you.

Not only that but when your tubing becomes dirty over time and condensation builds up contaminants can enter your lungs. And that’s the last thing your body needs. We recommend changing your CPAP tubing every 3 months.

How Often Should You Change Your CPAP Machine Air Filter?

If the filter in your CPAP machine starts to wear out or clogs it could be doing you more harm than you think. You may be exposed to airborne particles, mould and bacteria that a filter is designed to catch. Air filters are relatively inexpensive and ensure the air you’re breathing is pure. They also help your machine function better long-term. Change your air filters every 14 days to ensure the air your breathing is healthy and pure.

When Should You Get A New CPAP Humidifier Water Chamber?

If you notice your humidifier water chamber discolours or cracks it’s time to replace it. Cracking can occur due to mineral levels found in tap and drinking water. As the material of the water chamber deteriorates, even very slight cracks will trap bacteria. To avoid this we recommend replacing your humidifier water chamber every 6 months. And use distilled water as much as possible.

How Often Should You Replace Your CPAP Machine?

Your CPAP machine should last for at least 5 years. Although we recommend getting a backup machine after a few years. That way if something does happen to your machine, you have another one on hand while it’s being repaired. And then you won’t be caught out without CPAP therapy for a night. Your health is worth it.

Your CPAP supplies including machine and mask are designed to help you sleep better. And making sure they’re all in tip-top condition prevents a lapse in your snoring and sleep apnea. Keep track of how often you replace supplies in your calendar. That way if you notice any change at all in your CPAP therapy you’ll find it easier to pinpoint what might need replacing.

There’s simply no point continuing your therapy with CPAP supplies that just don’t work properly anymore. Even a slight change will affect your CPAP therapy success. Check the information that came with your CPAP machine for further guidance on replacement parts.
