How Often Should You Replace Your CPAP Equipment?

CPAP maintenance is an essential step of CPAP therapy. Part of which involves replacing your CPAP equipment regularly. By doing this vital step, you ensure that the hygiene of your equipment is high and to keep your CPAP supplies functionally optimally so you get the most out of your CPAP therapy. 

How often you should replace your CPAP equipment can vary depending on numerous factors, but we always recommend following the advice of your doctor, CPAP manufacturer and insurance company. The below however can give you a general timeline and point you in the right direction. 

The CPAP mask itself is the harder plastic portion, can be replaced about once every three months while the cushion (or nasal pillows) should be replaced once or twice per month.

This may seem too often, but keep in mind that the cushion makes direct contact with your face every night. Over time, dirt and oils from your skin can cause the cushion to soften so that it no longer forms a tight seal with your face. Leading to air leaks, which hinder your CPAP therapy's effectiveness, as well as hygienic purposes. 

Like your mask, your CPAP tube should be replaced every three months. With frequent use, your tubing can develop cracks or tears which can result in air leaks. If air is able to escape, you will likely not be receiving the proper treatment. Also, the tube can harbor bacteria, especially with moisture or condensation inside. 

Your CPAP humidifier water chamber can typically last around six months before needing to be replaced, but always be on the look out for cracking or signs of discoloration.
