CPAP and BiPAP humidifiers: find the right replacement
A compatible heated humidifier adds moisture to therapy airflow and may help reduce dryness in the nose or mouth. If your machine already has humidification, you may need only a replacement water chamber rather than a complete humidifier module. Start with the machine model and the part you need to replace.
This category also contains side covers, an oxygen-concentrator bottle and an HFNC chamber. These serve different purposes. A low-priced bottle or cover is not a substitute for the humidifier designed for your CPAP or BiPAP machine.
Current humidifier and water-chamber prices
Current prices include applicable tax. Check the exact version and package on the product page.
The live ranges separate replacement chambers, complete heated modules and side covers. Only in-stock, purchasable offers and available variations are counted. Oxygen bottles and HFNC chambers are excluded from CPAP price ranges. Open the individual listing to confirm the selected version, supplied parts and final checkout total.
Water chamber, heated module or side cover?
Water chamber or tub: the removable reservoir that holds water. It fits the matching humidifier system; purchasing the tub does not provide a separate heater or a therapy machine.
Heated humidifier module: an accessory assembly for a compatible device. Check whether its water chamber is included and whether you need a specific power, connection or tubing arrangement.
Side cover or end cap: a model-specific component for a supported configuration without the normal water tub. It does not add moisture. Follow the device instructions rather than simply operating with a missing chamber.

Match the exact machine family and part number before ordering. The names “HumidAir”, “DreamStation” or “prisma” alone are not enough to establish compatibility across every generation. The comparison identifies the type of item so a chamber-only offer is not mistaken for a complete module.
How to choose the correct part
Read the machine label. Record the full model, including its generation or series. AirSense 10 and AirSense 11 use different tubs. BMC G2S, G3 and RESmart GII also have separately listed replacements; do not assume that one BMC chamber fits every device.
Check the existing part. Look for a manufacturer reference and compare the chamber shape, seal and connection with the product details. If the label is unclear, share photographs of the machine label and current chamber with our support team.
Confirm what is supplied. A replacement tub, complete humidifier and side cover are different purchases. Check whether the offer includes the lid, seal, chamber and module as applicable. Heated tubing is a separate item unless explicitly included.
Select the correct variant. For prismaAQUA, the manufacturer specifies black and white versions for different device families. Choose by the exact machine and manufacturer reference, rather than colour preference. Ask our support team to check the selected option if you are unsure.
Comfort, dry mouth and condensation
Humidification can make PAP airflow more comfortable, but it does not replace prescribed pressure therapy or resolve every cause of dry mouth. Mask leaks can also contribute to dryness. If discomfort persists, ask your care team to review the mask fit and equipment settings.
Water droplets in the hose or mask are often called “rainout”: moisture condenses as humidified air cools. A compatible heated tube can help manage this, alongside the humidification and temperature controls supported by the device. Check the exact tube connection and machine support before ordering; a heated tube is not universal.
Browse our hose pipes and tubes for matching options. Use the manufacturer’s comfort-setting instructions and keep prescribed treatment pressure changes with your clinician.
Water, cleaning and replacement
Follow the water recommendation for the exact tub version. Requirements can differ between standard and cleanable chambers; do not assume that a rule for another model applies. Fill only to the marked maximum, allow heated parts to cool before handling, and follow the manual for emptying and drying.
Cleaning methods also vary. A “cleanable” chamber and a standard chamber may have different dishwasher or disinfection instructions. Use only the method specified for your part. Do not put oils, fragrances or medication into the chamber unless the manufacturer explicitly permits it.
Inspect the chamber, lid and seal for cracks, damage or persistent leaks. Arrange replacement or support when the part cannot be cleaned or sealed as instructed. A generic replacement interval is less useful than the exact manufacturer guidance and the condition of your chamber. Follow the manual when transporting the machine with its water tub.
Oxygen bottles and HFNC chambers are separate products
The oxygen-concentrator humidifier bottle and auto-fill chamber listed for BMC HFNC are intended for different equipment setups. They should not be fitted to a CPAP machine simply because they are displayed in the same category. Confirm compatibility, connections and the required clinical setup separately.
For help choosing a PAP replacement, send our support team the machine model, existing part number and whether you need a tub, full module or side cover. That information is more reliable than matching by brand or appearance alone.
Frequently asked questions
Do I need a water chamber or a complete humidifier?
If only the removable reservoir needs replacing, the compatible water chamber may be the required part. A complete module is a different assembly. Check the fault and supplied parts with our support team before ordering.
Will an AirSense 11 water chamber fit AirSense 10?
No. HumidAir 11 and Air10 HumidAir tubs are different parts. Match the chamber to the exact device generation and manufacturer reference.
Is the DreamStation water chamber a complete heated humidifier?
No. The chamber is the removable water reservoir. The complete DreamStation heated humidifier is a separate listing. Confirm the machine generation before choosing either part.
Which prismaAQUA version should I choose?
Löwenstein specifies the black version for prismaLINE and the white version for supported prisma SMART/SOFT and prisma VENT families. Confirm the full device model and part number against the selected variant before ordering.
What water should I use in a CPAP humidifier?
Follow the instructions for the exact chamber version. Standard and cleanable tubs can have different water requirements. Do not assume that guidance for another machine or chamber applies.
Can I wash every water chamber in a dishwasher?
No. Cleaning and dishwasher suitability depend on the model and chamber version. Follow the supplied manual and use only its recommended cleaning method.
Will a heated hose stop water collecting in my mask?
Compatible heated tubing can help reduce condensation, but the result also depends on supported humidity and temperature settings and room conditions. Check machine compatibility and follow the manufacturer’s instructions.
Does a side cover provide humidification?
No. A side cover or end cap does not add moisture. Use it only in the compatible configuration specified for your machine.
Can I use an oxygen bottle or HFNC chamber with my CPAP?
Do not assume compatibility. These products are designed for different equipment setups and are not universal replacements for a CPAP water tub.
Where can I find the current price?
The live price cards and comparison table use current in-stock WooCommerce offers. Open the selected product for its exact version, package and checkout price.
