How to Know When to Replace My CPAP

As a CPAP machine user, you have to keep up with your equipment’s maintenance. When you fall behind on that, its functionality and your health get put at risk. You require your machine to work at peak performance to treat sleep apnea, so take care of it.

For example, did you know you have to replace your CPAP equipment every so often? To tell you more about when to, our specialists at CPAP Liquidators are here. Read on, and when it’s time to replace yours, shop our selection of new and refurbished CPAP and BiPAP machines.

The CPAP Machine

There isn’t a solid answer for how long a new CPAP machine will last. It varies based on the brand and model that you select. However, the average range is about three to five years. Keep in mind this is just the life expectancy for the machine itself. There are other parts to worry about, too.

If your medical insurance covers any of your machine’s costs, they’ll be aware of your replacement schedule. You can always check with them to see when you’re due for new gear.

The CPAP Mask

CPAP masks are one of the parts that get replaced routinely. The typical lifespan of one is roughly three to six months. Beyond that, signs of wear and tear start to take over.

The mask’s cushion gets replaced even more often than the mask itself. Most patients find that once or twice per month is suitable. Your skin’s natural oils deteriorate the cushion, so it has to get changed more frequently.

Other CPAP Accessories

You’re not done yet! Other CPAP accessories need to get replaced every so often. About once a month, the machine’s white filter needs to get changed.

Every three months, it’s time for new air hoses. By the six-month mark, it’s time for new black or grey filters and a different humidifier water chamber. This is also when your headgear should get swapped for a new set.

Inspect Your Gear Often

In addition to keeping up with replacement schedules, take time to inspect your gear. Check items like chin straps or the face mask cushion for rips or deterioration. Watch out for holes in your tubing. See if your filters are getting dirtier faster than they should. If you take care of your equipment, it will last much longer.


If you’re on CPAP therapy, it’s crucial to replace your equipment regularly. Wear and tear causes damage, which can later interrupt the efficiency of your machine. Prevent this by making regular upkeep a priority.
