How Long Does a CPAP Machine Last? 4 Signs It's Time For a New CPAP

If you’re reading this, you might have noticed that your CPAP machine isn’t as effective as it once was. Maybe your machine is starting to make strange noises, or you’re feeling fatigued again. Whatever the reason, it’s important to take action before your CPAP machine fails. There are 4 common signs that you can look out for. We’ll also cover tips to try out before giving up on your machine, and more importantly, what to do when it’s time to go ahead and replace it.

1. Your CPAP Machine Makes Noise When Inhaling

It’s normal for your CPAP machine to make some noise, but it shouldn’t change with every inhale. First, rule out air leaks in your CPAP mask or cracks in your tubing. These parts should be replaced every 3 months and are usually covered by your insurance that often.

If you’ve replaced both and your machine is still making unusual noises, it could be a sign that the motor is failing, which means you might not receive the proper air pressure for your therapy. 

2. Your Humidifier Doesn't Need To Be Refilled As Often

Are you noticing your water level isn’t going down? That’s a sure sign something is wrong. If your humidifier isn’t built into the machine, disconnect it and see if your machine works without it. Replacing the humidifier may be less costly than replacing the entire device.

You will need a prescription to order a new humidifier, whether it’s covered by insurance or not. If you need help finding or updating any prescription, your Aeroflow Sleep Specialist can contact your doctor and take care of it! Call us directly at 866-616-1687.

3. You're Still Snoring With CPAP Use

Snoring is extremely common with sleep apnea, but you shouldn’t be snoring while using your CPAP. If you’ve started snoring again, it means that your pressure isn’t strong enough to prevent your airway from collapsing.

Before you point fingers at your machine, try the following first:

• Sleep on your side; sleeping on your back or stomach can contribute to the blocking of your airways.
• Check your CPAP mask for leaks; ensure that your seal is tight, that there are no cracks in your mask cushion, and that your headgear hasn’t stretched.
• Switch to a full face mask or buy a chinstrap to go with your nasal/nasal pillows mask; if you sleep with your mouth open, your air pressure may be escaping as you breathe.

If you’ve tried all of the above and you’re still snoring, your machine may no longer be able to provide the pressure you need. Whether your snoring is due to a machine in need of repairs or because of lifestyle changes—like weight gain—talk to your doctor or healthcare provider about adjusting your air pressure.

4. You Wake Up Still Tired With CPAP Use

Suddenly struggling with excessive daytime sleepiness again could indicate your CPAP machine is failing to deliver adequate sleep apnea therapy. As with snoring, try to rule out any other reasons that may contribute to a loss of air pressure. If you’re still finding yourself in need of a nap, talk to your doctor about the return of these symptoms, too. They may recommend adjusting your pressure settings or addressing other lifestyle factors. Or, it may be time to replace your old CPAP machine.

We recommend replacing your machine if it is around 5 years old. Don’t wait until these 4 signs appear, or your CPAP device could fail to deliver effective therapy. While a CPAP machine's life expectancy is 5 years, the good news is that 5 years is also when most insurance providers (including Medicare and Medicaid) will likely cover a replacement CPAP machine!

That makes it a great opportunity to upgrade to improved technology and comfort features that can enhance your sleep quality; including…

• Heated humidification
• AHI Monitoring
• Autoset functionality

Though some CPAP users can prolong the life of their CPAP equipment with diligent cleaning and maintenance, you shouldn’t gamble on that. When the manufacturer, insurance company, and Aeroflow Sleep agree, you should plan on that timeframe.

All of this is good for your machine, but your CPAP supplies need regular replacement, too. We previously mentioned that your mask and tubing can be ordered every three months. Each of your accessories has an expiration date, here is a recommended timeline for when they should be replaced:

Just like for your machine, following a replacement schedule is essential when dealing with sleep apnea. Failing to do so makes it easier for bacteria, mold, viruses, allergens, and other irritants to build up; increasing your risk of getting sick.
