This is general information, not medical advice. ## The Types of Sellers Most reputable options fall into a few categories: - **Medical equipment providers:** established, handle insurance, often offer support - **Manufacturer-direct stores:** buy certain brands straight from the maker - **Online sleep retailers:** broad catalogs, competitive prices - **Clinics and sleep centers:** can sell or refer you to trusted sources What you generally want to avoid is generic marketplaces and peer-to-peer listings where condition, warranty and authenticity are unclear. ## What Makes a Seller Trustworthy Look for these green flags: - **A valid prescription requirement** (a sign they follow the rules) - **Clear return and exchange policy**, especially for masks - **Manufacturer warranty** honored - **Mask-fitting guidance** or a fit guarantee - **Responsive support** by phone or chat - **Real contact information** and a physical address If a store sells a machine with no prescription and no questions, that is a warning sign. In the US, machines require a prescription. ## Prescriptions and What You Need Before you order, have: - A **valid prescription** for the machine type - Your **pressure settings** or auto range from your clinician - **Mask size** and style preference - Insurance details, if using coverage If you do not have a prescription yet, a sleep evaluation comes first.

Suspicious, she chose a reputable retailer instead. The price was modestly higher, but it included a mask, a fit guarantee and a warranty. When her first mask leaked, the seller exchanged it free. The small price difference bought real support. ## Frequently Asked Questions ### Can I buy a CPAP machine online without a prescription?
