3B Medical CPAP & Home Health Products

3B Medical builds its reputation on the Luna line of CPAP and BiPAP machines, and much of what you'll find here keeps those devices running the way they should. If your Luna is running dry at night, waking you with a scratchy throat, or you're chasing down a replacement part months after the machine itself is out of warranty, this is where those pieces live.

Humidification and tubing are the two components that wear out or get misplaced first. We stock the Luna II G2 and Luna G3 heated tubing (both 6-foot lengths) along with the matching water chambers — the LG24510 for the G2 and LG34510 for the G3. It's worth checking your machine's exact generation before ordering, since the G2 and G3 chambers and tubing are not interchangeable. Heated tubing is what prevents rainout, that pooling of condensation that happens when warm humidified air meets a cold hose, so if you've been getting water in your mask, this is usually the fix.
