Lightweight, compact designs with universal power supplies mean your therapy travels with you wherever you go.
CPAP Machines Collection
A CPAP (Continuous Positive Airway Pressure) machine delivers a constant stream of pressurised air through a tube and mask to keep your upper airway open during sleep. This prevents the airway from collapsing, which is the primary cause of obstructive sleep apnoea (OSA).
The machine draws in room air, filters it and pressurises it to a level prescribed by your clinician. This gentle, continuous pressure acts as a pneumatic splint, eliminating apnoeas, hypopnoeas and snoring.
CPAP delivers a fixed, constant pressure set by your prescribing clinician. It is the most common type and works well for most OSA patients.
APAP (Auto CPAP) automatically adjusts the pressure breath by breath within a set range. This can improve comfort and is particularly useful for patients whose pressure needs vary, such as those who sleep in different positions or whose OSA severity changes.
BiPAP (Bilevel PAP) delivers two different pressure levels — a higher pressure on inhalation and a lower pressure on exhalation. It is used for patients with more complex respiratory needs, higher pressure requirements or conditions such as central sleep apnoea or COPD.
Your prescribing clinician will recommend the most appropriate device based on your sleep study results.
In the UK, CPAP machines are classified as medical devices. While a prescription is not legally required to purchase a machine, a formal sleep study and clinical assessment are strongly recommended before starting therapy. This ensures the correct pressure settings are identified and the most appropriate machine is selected for your condition.
If you have already been diagnosed with sleep apnoea and are replacing an existing machine or purchasing a spare, our team can assist you in selecting a compatible device. Contact us if you need guidance.
The right machine depends on several factors including your diagnosis, prescribed pressure range, lifestyle and personal preferences. Key considerations include:
Fixed vs auto-adjusting: APAP machines are often preferred for their flexibility and improved comfort, particularly for new users.
Built-in humidifier: Most modern machines include an integrated humidifier. If yours does not, a standalone or clip-on humidifier can be added.
Noise level: All our machines are clinically quiet, but models vary slightly. Consider this if you or your partner are sensitive to sound.
Travel use: If you travel frequently, a compact, lightweight model with a universal power supply and optional DC cable is advisable.
If you are unsure, please contact our clinical team for guidance before purchasing.
Setting up a CPAP machine for the first time is straightforward. The general steps are:
1. Place the machine on a flat, stable surface beside your bed, ideally below the level of your head.
2. Fill the water chamber with distilled water up to the maximum fill line and attach it to the machine.
3. Connect the tubing to the machine's air outlet and the other end to your mask.
4. Fit and adjust your mask for a secure, comfortable seal.
5. Power on the machine and begin therapy. Many machines start automatically when you breathe in.
Your machine will come with a detailed user manual. If pressure settings need to be configured, refer to your clinical team or prescription paperwork.
Daily: empty any remaining water from the humidifier chamber and leave it open to air dry.
Weekly: wash the water chamber and tubing with warm water and mild soap. Rinse thoroughly and allow to dry completely before reassembling. Wipe the exterior of the machine with a damp cloth.
Monthly: inspect and clean reusable filters by rinsing with water. Allow to dry fully before replacing.
Every 6 months: replace the water chamber and any reusable filters. Replace disposable filters every 1 to 3 months depending on use.
Avoid harsh chemicals, bleach or alcohol-based products on any components, as these can degrade seals and plastic.
Yes. Most modern CPAP machines are designed for travel. They typically include a universal AC power supply (100–240V) suitable for use in any country. Many models also support DC power for use in cars, campervans or off-grid settings via an optional DC cable or battery pack.
CPAP machines are classified as medical devices and are permitted as carry-on luggage on most airlines. It is advisable to carry your prescription documentation when travelling internationally.
If you travel frequently, consider a purpose-built CPAP travel bag to protect your equipment during transit.
CPAP pressure is measured in centimetres of water pressure (cmH₂O) and should only be set based on the results of a titration study or the recommendation of your prescribing clinician. Common therapeutic ranges are between 4 and 20 cmH₂O.
If you are using an APAP device, your clinician will set a minimum and maximum pressure range within which the machine will automatically adjust.
Do not self-adjust your pressure without clinical guidance, as incorrect settings can reduce therapy effectiveness or cause discomfort.
A well-maintained CPAP machine typically lasts between 5 and 7 years, though many continue to function reliably beyond this. Lifespan depends on usage frequency, maintenance habits and the specific model.
Regular cleaning, timely filter replacement and using distilled water in the humidifier are the most effective ways to extend the life of your machine.
If your machine begins to make unusual noises, loses pressure consistency or displays persistent error codes, it may be time to consider a replacement. Contact our team for advice.
A 30-day change-of-mind return policy is available for brand new machines that are unopened and unused only. Once a CPAP machine has been set up or used, even briefly, it cannot be resold as new for hygiene and clinical reasons.
If you receive a machine that is faulty or damaged on arrival, please contact us immediately and we will arrange a replacement or refund.
Return shipping costs for change-of-mind returns are the responsibility of the customer. We strongly recommend selecting the correct model before purchasing. Our team is available to help you choose the right machine.
