Choosing the right heated CPAP hose is an often underestimated but crucial factor for successful and pleasant CPAP therapy. In our day-to-day consulting practice, we see avoidable errors being made time and time again when it comes to choosing and caring for CPAP hoses – sometimes with unpleasant consequences for the user. We also receive frequent questions relating to the compatibility of masks and devices. In this blog article, we explain what you need to look out for.
Unheated hoses – the alternative to heated CPAP hoses for beginners
In the initial equipment version, CPAP devices are usually delivered with an unheated standard hose. The heated hose then needs to be ordered separately if required.
Unheated CPAP hoses are usually 1.8 metres long, which offers most users sufficient freedom of movement without impairing the effectiveness of the flow of air. Alternatively, shorter (e.g. 60 cm) or longer (up to 3 m) hoses are also available.
A standard CPAP hose consists of:
- Rubber sleeve: With a standardised connection diameter of 22 mm, the hose fits on almost all CPAP masks and devices – with the exception of special systems such as the ResMed AirMini.
- Centre section: The actual hose has an inner diameter of 15 mm (SlimLine) or 19 mm as standard. The 15-mm hose is particularly light and flexible. This is beneficial for sensitive users in particular, as it means there’s less tension on the mask. It is important to note that the CPAP device needs to be set to the correct inner diameter in order to correctly adapt the positive pressure.

Advantages and disadvantages of unheated CPAP hoses
Tip from practical experience: Time and again, we receive messages from customers saying that the hose cannot be connected to the CPAP mask. This “problem” can usually be resolved quickly and easily. If the hose does not fit correctly, check to see whether there is still an old elbow or a quick-release fastening from your mask in the rubber sleeve — a frequent yet easily resolvable issue.
Heated CPAP hoses – comfortable solution to prevent condensation and dryness
Heated hoses feature an integrated heating wire that regulates the air temperature within a range of 25 to 30 °C. This not only ensures pleasantly warm air, but also prevents the formation of condensation – a common disruptive factor with CPAP use. With these hoses, the power comes directly from the CPAP device and the temperature can be individually adjusted.
Important information on compatibility: Heated CPAP hoses are usually only compatible with certain CPAP device models, as the electrical connections are not standardised. This applies both to devices from different manufacturers and to models from the same manufacturer. For example, a ResMed ClimateLineAir hose only fits models in the AirSense 10 series, but does not fit other ResMed devices or devices from other manufacturers.
Our recommendation: before making a purchase, always read the information in the product description and check whether the hose is suitable for your device model.

Cleaning and care – keeps your CPAP hose hygienic and functional
Consistent cleaning not only extends the service life of the hose, but also protects against germs and mould. We recommend thoroughly cleaning the hose at least once a week.
This is particularly easy with a liquid CPAP cleaner and a special CPAP hose brush.
After cleaning, the CPAP hose should be dried before being reused. The best way to dry the hose? Simply hang it up vertically and let it drip dry for a day, or alternatively connect it to the CPAP device without the mask and let air run through it for 20-30 minutes. Never use a hair-dryer, as the hot air could damage the material.
Despite being electrical items, heated hoses from ResMed, Philips and Löwenstein can also be cleaned in a water bath. Due to the angled connection, however, the use of a cleaning brush is limited.
Important: Do not use any cleaning agents that contain alcohol, and do not clean in the dishwasher!
Replacement interval: A hose should be replaced every 6 to 12 months – or sooner in the event of visible damage, unpleasant odours or material changes.
Accessories for more comfort and effectiveness
To make your CPAP therapy as pleasant as possible, there is a range of practical accessories for your CPAP hose:
- Hose covers: Insulate against the cold, reduce condensation even when using unheated hoses, and make the hose pleasantly snuggly against the skin. However, these must not be used together with heated hoses.
- Hose holders: Guide the hose upwards and away from the bed, thereby protective against tension on the mask. Increases freedom of movement during sleep.
- CPAP cleaning brushes: Allow for thorough cleaning of the inside of hoses – often only suitable for unheated hoses due to the connection.
Conclusion: the right hose makes all the difference
The decision as to whether to buy a heated or unheated CPAP hoses depends on your individual requirements.
Unheated models offer a solid basic option. They are good value and very versatile. For a more affordable alternative, they can also be combined with a hose cover to prevent condensation. For anyone looking for ultimate comfort, however, it makes sense to invest in a heated hose.
Whether heated or unheated – the following point is crucial: carry out regular hose care and replace your hose in good time.
