CPAP questions, explained in plain language.

For U.S. orders, a valid prescription is required before we ship CPAP machines and masks intended for personal use. You may place the order first and provide the prescription afterward. International and verified reseller orders follow different requirements.

Prescriptions may be written by properly licensed professionals, including physicians, physician assistants, nurse practitioners, dentists, and qualifying naturopathic physicians, subject to applicable regulations.

Yes. Send us your machine and current mask model, plus the part you need. Most modern masks use a standard hose connection, while travel machines and specialty tubing may require specific adapters.

Included items vary by listing. Machines normally include a hose, often stored in the zippered compartment of the carrying case. Review the product description and photos, or ask us to confirm before ordering.

Eligible, ready-to-ship orders completed before 3:00 PM Arizona time generally ship the same business day. Orders completed after the cutoff generally ship the following business day. Prescription-required orders must be cleared before the cutoff. Weekends and holidays are excluded.

Yes. Available carriers and speeds appear at checkout. International buyers are responsible for applicable customs fees, duties, and import taxes. U.S.-market cellular features may not work outside the United States.

Orders over $200 USD require signature confirmation for delivery.

Heated hoses are designed to reduce condensation and may not feel warm to the touch during normal operation.

Use distilled water only. Tap or mineral water can cause buildup and may lead to damage that is not covered by warranty.

Wash removable components regularly with mild soap and warm water, then air-dry them away from direct sunlight. Never submerge the CPAP machine.

Machine power supplies generally support international voltage. You may still need a region-specific plug or power cord.

New CPAP machines include a 2-year in-house warranty for the device and power supply unless the listing says otherwise. Hoses and water chambers include 6 months of warranty coverage.

Eligible machines and unopened masks may be returned within 30 calendar days of purchase. Restocking fees and condition requirements apply. Opened or used masks cannot be returned for hygiene reasons. Review the full return policy before ordering.
