How often should you replace your CPAP supplies?


If you use a CPAP or BiPAP for sleep apnea therapy each night, you should be eligible for free replacement supplies through your insurance. It’s important to inspect and replace your CPAP/BiPAP supplies as often as needed to ensure a proper fit, comfort, and cleanliness.

Note: the following are the industry standard recommendations which many, but not all, insurances follow. Please be sure to check with your insurance to verify how frequently you are eligible to replace your supplies!


Mask Cushions / Pillows

Nasal mask cushions or nasal pillows should be replaced every 14 days.

If you have a full face mask, that should be replaced every month.


Mask Frame

Every 3 months is when you will want to replace your mask frame system. This allows your treatment to remain comfortable.


Mask Headgear

Every 6 months, you should replace your mask headgear. You may feel you have to tighten the straps more often because the straps have lost their elasticity. This is a good sign for replacement.


Air Filters

Replace air filters every 14 days. Dirt and dust build up over time, which leads to blockages and bacteria. Just as you replace your furnace filter, you need to replace this filter too (only it’s a little more pertinent you do so on time, as you are directly breathing in air from this filter.)


Tubing / Hose

Air tubing should be switched out every 3 months. Holes and tears can cause air leaks, so your treatment will be less effective.


Humidifier Water Chamber

Your humidifier water chamber (tub) can be replaced every 6 months, as these can become discolored or cracked which leads to excess bacteria.


CPAP and BiPAP (BiLevel) Machines

Every 5 years is the time to check to see if you need to replace your entire machine. This can ensure you are getting the therapy you need and take advantage of any new technology or enhanced comfort settings!


With all of this comes the need to mention cleaning your mask and accessories daily. Be sure to use warm, soapy water and/or cleaning wipes made especially for CPAP devices. You can also purchase a sanitizing system to help. You can shop all CPAP Care Items here:
