Buying checklist
What to verify
| Check | Why it matters |
|---|---|
| Exact model or mask family | Many CPAP parts look similar but are not interchangeable. |
| Size and package contents | Some listings sell one cushion, while others sell multipacks or kits. |
| Return policy | Medical-style accessories may have stricter return rules. |
