CPAP Humidifier, Water Chambers and Parts

For greater comfort and to prevent CPAP side effects such as dry mouth and nose, we highly recommend using a CPAP humidifier with your machine. Heated humidifiers consist of a water chamber and heated plate which heats up the water to add moisture into the dry air from the CPAP.

Users can adjust the humidity level or set it to auto mode (available only on select CPAP machines) to let the machine keep humidity at a optimum level. 

For most patients using a CPAP machine, humidified air is essential for getting a good night's sleep. This is because the air from your CPAP or BiPAP (also called a VPAP) machine doesn't contain any moisture and can dry out your mouth, nose and throat, causing you to wake up with cotton mouth, sore throat, nasal congestion and even a bloody nose.

These side effects can make adjusting to sleep apnea therapy difficult and prevent regular CPAP use. Learn more about how CPAP humidifiers work, the different types of humidifiers and proper humidifier care with our CPAP humidifier guide.

At RespShop, we have a wide selection of heated humidifiers to choose from that are designed to work with different CPAP machines. Give our CPAP experts a call and they can direct you to the best humidifier for your unit. 

For the convenience of our CPAP customers, we also sell high-quality CPAP humidifier water chambers and replacement CPAP humidifier parts.

Water chambers can accumulate mineral and calcium buildup over time and should be replaced regularly to maintain optimal performance and quality of therapy. We carry water tanks for various CPAP and BiPAP machines. You'll also discover a variety of replacement parts for your CPAP humidifier, such as heated tubing, replacement hoses, hose covers, inlet seals, and sealing gaskets.

Note: If you're looking for a more compact CPAP machine with humidification, Fisher and Paykel's SleepStyle Auto, ResMed's AirSense 10 and AirSense 11 include built-in humidifiers.
