Knowing when to replace your supplies

Your CPAP system is made up of multiple parts. Just like a car, the system works best with proper maintenance, which involves the replacement of certain parts at times. Many sleep apnea patients may not realize the importance of replacing their CPAP supplies to ensure a comfortable, proper fit and maximum effectiveness. When your CPAP system is working at its best, you'll be able to tell the difference. In fact, 7 in 10 PAP patients say they sleep better after replacing their supplies. And 1 in 3 say they get more sleep after replacing supplies.1

General guidelines* on when to replace different CPAP supplies:

Cushion

Nasal, nasal pillows masks
Nasal mask cushions are in constant contact with your face and nasal pillows sit inside your nose throughout the night. Regular replacement is recommended for hygienic purposes and to ensure the best fit.
Every
Full face masks
Full face mask cushions cover more of your face and may deteriorate over time through regular wear and tear. Regular replacement is recommended for hygienic purposes and to ensure the best fit.
Every

Air filter

Air filter
CPAP device air filters can wear out or become clogged over time, potentially exposing you to airborne particles, mold and bacteria.2
Every

Frame system

Frame system
The frame system is comprised of the mask frame and cushion. Due to being in close proximity to the face during treatment, frames should be regularly replaced. However, since not in direct contact, the frame system is only eligible for replacement every three months.
Every

Tubing

Tubing
CPAP mask tubing may develop small holes or tears, which can cause air leaks. If your tube is leaking, you may not be receiving your prescribed therapy setting from your CPAP. This can cause you to feel like you’re not sleeping as well.
Every

Headgear

Headgear
CPAP mask headgear and chin straps may become stretched and lose their elasticity, leading to over-tightening and discomfort. They can also trap bacteria from sweat and moisture.
Every

Humidifier water chamber

Humidifier water chamber
CPAP humidifier water chambers may become discolored, cracked, cloudy or even pitted due to the mineral levels found in most tap and drinking water. As the material deteriorates, cracks may trap bacteria from moisture.
Every

CPAP Machine

CPAP machine
A CPAP machine's life span is typically 5 years. We recommend getting a backup CPAP machine, especially if your current machine is more than two years old. That way you’ll never be without your therapy, even if one of your devices requires maintenance.
