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.

General guidelines* on when to replace different CPAP supplies:

Nasal mask cushions are in constant contact with your face and nasal pillows sit inside your nose throughout the night. Regular replacement every 90 days is recommended for hygienic purposes and to ensure the best fit.

Full face mask cushions cover more of your face and may deteriorate over time through regular wear and tear. Regular replacement is recommended every 90 days for hygienic purposes and to ensure the best fit.

CPAP device air filters can wear out or become clogged over time, potentially exposing you to airborne particles, mold and bacteria.Replace your filters every 30 days.

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. Replace your tubing every 6 months.

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. Replace your headgear every six months

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.Replace your water chamber every six months.

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.
