A CPAP machine delivers a single, constant pressure throughout the night. An APAP machine automatically adjusts pressure breath-by-breath based on your needs. A BiPAP machine provides two pressure levels: higher when you inhale and lower when you exhale, typically prescribed for more complex sleep-disordered breathing.

Yes. In the UK, CPAP and BiPAP devices are classified as prescription-only medical devices. We may request a copy of your prescription or a clinician letter before dispatch. Accessories such as masks, tubing, filters, water chambers, and headgear can be purchased without a prescription.

We carry devices from the most trusted names in sleep therapy, including ResMed (AirSense 11, AirSense 10 series), Löwenstein Medical (prisma SMART and prisma 20A), and other leading manufacturers. Our range covers auto CPAP, fixed-pressure CPAP, BiPAP, and travel machines.

Travel CPAP machines like the ResMed AirMini are compact, lightweight devices designed for portability. They typically offer the same therapeutic pressures as full-size units but may lack a built-in humidifier. Many users do use travel machines as their primary device, but if comfort features like heated humidification are important, a full-size machine is usually better for home use.

Full Face Masks cover both the nose and mouth — ideal if you breathe through your mouth. Nasal Masks cover only the nose. Nasal Pillow Masks sit at the nostrils with minimal contact, perfect for side sleepers or those who feel claustrophobic.

Most manufacturers provide a sizing template you can print and hold against your face. If unsure, check the sizing guide on the product page or email us at info@cpapsupply.co.uk before ordering.

In most cases, yes. Standard CPAP masks use a universal 22mm hose connector. However, some travel devices (like the ResMed AirMini) use proprietary connectors and may require specific masks or adaptors.

The full mask assembly should be replaced every 12 months, cushions every 3–6 months, and headgear every 6–12 months.

Ensure headgear straps are not over-tightened, wash the cushion with warm water and mild soap, and check if the cushion is worn or cracked. Worn cushions are the most frequent cause — replacement cushions are available individually.

Absolutely. We sell individual replacement parts including cushions, pillows, headgear, frames, and elbow clips.

Each replacement cushion specifies the exact compatible mask models. Check the product title and compatibility section on the product page.

Disposable filters should be replaced every 2–4 weeks. Reusable filters can be washed weekly and replaced every 6 months.

Yes. We carry replacement humidifier water chambers, standard tubing, and heated tubing. Water chambers should be replaced every 6–12 months, and tubing every 3–6 months.

Daily, empty and rinse your water chamber. Weekly, wash your mask cushion, headgear, tubing, and water chamber with warm water and mild, fragrance-free soap. Allow everything to air dry.

Use distilled water. Tap water contains minerals that leave calcium deposits. Distilled water extends chamber life and keeps therapy clean.

Yes. CPAP-specific pillows have contoured cutouts that accommodate your mask and tubing, reducing pressure on the seal and preventing leaks — especially for side sleepers.

A chinstrap holds your jaw closed during sleep, preventing mouth breathing and air leak. If you use a nasal mask and your mouth falls open at night, a chinstrap can help.

Most modern CPAP machines have universal voltage power supplies (100–240V, 50/60Hz), so they work anywhere. You will just need a plug adaptor for the destination country.

We stock portable CPAP batteries from Medistrom and other brands — ideal for camping, flights, or power outages. Check each battery product page for compatibility charts and estimated run time.

CPAP machines are FAA-approved for in-flight use. Most airlines allow you to carry your CPAP as a medical device. Contact your airline in advance and remember to empty your humidifier before boarding.

If powering from a car, caravan, or boat, you will need a DC/DC converter or manufacturer-specific 12V/24V adapter. Never use a standard mains inverter.
