Fix Your CPAP Problems.
Sleep Better Tonight.

Mask cushions should be replaced every 1–3 months, headgear every 6 months, tubing every 3 months, disposable filters every 2 weeks, reusable filters every 6 months, and water chambers every 6 months. Use our free Supply Calculator to check your schedule.

Daily, wash your mask cushion with mild soap and warm water. Weekly, clean your tubing, headgear, and water chamber with warm soapy water. Let all components air dry away from direct sunlight. Never use harsh chemicals, bleach, or a dishwasher.

There are three main types: Full face masks cover both nose and mouth (best for mouth breathers), nasal masks cover only the nose (good balance of seal and comfort), and nasal pillow masks use small cushions at the nostrils (most minimal and great for side sleepers).

Signs of incorrect pressure include mask leaks, difficulty exhaling, aerophagia (swallowing air), or continued snoring. Modern auto-adjusting CPAP machines (APAP) adjust pressure throughout the night. Always consult your sleep specialist before changing pressure settings.

Yes. CPAP machines are allowed as carry-on medical devices by all major airlines and do not count toward your bag limit. Bring a copy of your prescription, consider a travel-sized machine, and check if you need a power adapter for international destinations.

Dry mouth is usually caused by mouth breathing during sleep or insufficient humidification. Solutions include using a heated humidifier, trying a chin strap, switching to a full face mask, or adjusting your humidifier settings higher.

Common noise causes include an old or dirty filter, a worn-out motor, mask leak vibrations, or the machine sitting on a hard surface. Try cleaning or replacing filters, placing the machine on a soft surface or towel, and checking all connections for air leaks.

Most insurance plans, including Medicare, cover CPAP supplies on a replacement schedule. Medicare typically covers new masks every 3 months, cushions monthly, tubing and filters quarterly, and machines every 5 years. Check with your specific plan for coverage details and any compliance requirements.
