Don’t let paperwork stop your order.
For U.S. personal-use orders, machines and masks require a valid prescription before shipment. Most replacement supplies do not. We make the required step clear before checkout.

Frequently asked questions
Quick, plain-language answers.
Still unsure? Our team can walk through the details with you.
Do I need a prescription for a CPAP machine?+
For U.S. personal-use orders, a valid prescription is required before shipment for CPAP, APAP, BiPAP machines, and masks. International and verified reseller orders follow different requirements.
How do I know whether a mask fits my machine?+
Most modern masks use a standard hose connection. We still check the complete setup, especially travel machines and specialty tubing.
What does “open box” mean?+
The packaging has been opened, but the equipment is unused. We inspect the item and clearly list its packaging and included accessories.
Can someone help me place an order?+
Yes. Call 480-625-8822 or send us a question and tell us that you would like assisted ordering.
