CPAP Humidifier Parts

Shop CPAP Humidifier Replacement Parts

During the course of your sleep apnea therapy journey, you’ll likely find yourself replacing just about every part of your CPAP setup at one point or another to ensure your equipment is working as it should. Some parts, such as your mask cushions, air filters, and headgear, need to be replaced more often than parts like your humidifier chamber or its seals and gaskets. Your humidifier chamber, however, isn’t bulletproof, but it will last you six months to a year on average before requiring replacement. 

Apart from your humidifier, you’ll also notice that there are some inlet and outlet seals that keep water where it’s supposed to be and air flowing the way it should. These seals will also need to be replaced when they start to wear out to maintain therapy effectiveness. Here, you’ll find replacement seals and gaskets for your humidifier chamber, HumidX replacement pucks for the ResMed AirMini, and an assortment of humidifier parts for older machines, like the PR System One and ResMed S9. 

When to Replace Your Humidifier Parts

While it isn’t always obvious, most of the time, you should be able to tell when a replacement part is needed, based on if your humidifier is working properly or not. The first sign of humidifier trouble is that the air coming from your CPAP machine won’t be humidified, causing you to experience the pains of dry mouth, throat, or nose, such as air passage soreness, nose bleeds, tooth irritations, bad breath, etc. 

If you are not receiving your typical humidified air, your humidifier could not be seated properly, the heating plate may not be working, or there may not be water in the chamber. If there’s an issue with your chamber itself, there will likely be a noticeable leak or crack. As long as you only use distilled water and don’t drop your humidifier chamber, it will likely last much longer than the recommended six-month replacement window. What’s more likely, however, is a faulty humidifier seal or gasket. Indicators that it may be time to inspect and replace your humidifier seals include an uncharacteristic hissing noise from your humidifier or an unusually high amount of water left in the humidifier reservoir in the morning.

Over time, humidifier seals and gaskets can also deteriorate, and the subtle vibrations from your machine can gradually unseat these parts, which increases the risk of water ending up in the sensitive electronics of your machine. If you frequently travel or relocate your CPAP machine, you may dislodge or misalign your seals without realizing it, so be sure to check that everything is lined up and secure in place before using your machine after moving it.

To ensure peak functionality, it’s important to clean your humidifier chamber weekly with mild soap and warm water. You should, however, empty and dry your humidifier chamber after each use. By also following the recommended replacement schedule, you can help ensure that your machine stays in proper working order. After about six months of machine use or when you start to notice changes in your therapy, you’ll want to begin inspecting your seals about once a month to ensure everything is in proper working order.

If you need help finding the right part, our Part Finder Tool is an excellent resource for locating some of the less-common parts that are associated with your machine, like your humidifier seals and gaskets.

Commonly Purchased Humidifier Replacement Parts and Accessories

Here’s a short list of some of the more popular humidifier replacement parts and accessories we sell:

• Side Cover for the AirSense 10, AirStart 10, and AirCurve 10: If humidification isn’t for you, this unique accessory that’s designed for the AirSense 10, AirStart 10, and AirCurve 10 replaces your humidifier chamber for a sleeker look and more compact size while also slightly reducing your machine’s sound output. 
• Standard HumidX 6 pk for AirMini: A product designed to add waterless humidification to your AirMini Travel CPAP without the need to travel with distilled water, the HumidX uses paper ridges to capture the moisture from your exhaled breath to humidify your incoming inhaled air for a more comfortable therapy experience. Should be replaced every 30 days for best results. Pack of six. 
• HumidX Plus 6 pk for AirMini: The paper puck inside of the HumidX Plus features a wider radius than the one found in the standard HumidX, making it more effective at trapping moisture and re-administering it to you. It is designed for use in arid climates and high altitudes where humidity is especially low. Should be replaced every 30 days for best results. Pack of six. 
• ResMed AirSense 10 Air Outlet Adapter: For all AirSense 10 CPAP models as well as the AirStart 10 and AirCurve 10, this replacement humidifier chamber air outlet is where humidified air exits your humidifier chamber and enters your CPAP hose. 
• Humidifier Control Pressure Valve: An optional accessory, this humidifier pressure valve is designed to keep the water in your humidifier chamber from accidentally flowing into the sensitive electronics of your machine. It acts as an additional defense against costly machine damage.

Please Note: HumidX for AirMini is only compatible with mask setup packs that are designed for the AirMini. If you use the Zephair Adapter and a standard CPAP mask and tube, you can still enjoy waterless humidification with the generic Heat Moisture Exchange (HME) Units.
