CPAP users, these magnetic clips are absolute game-changers for making your nightly routine so much easier! If you have a ResMed AirFit F30i, F40, F20, N20, or N10 mask, these clips snap right onto your headgear with strong magnets. No more struggling to connect your mask - just bring it close and they snap together perfectly. Makes those middle-of-the-night bathroom breaks way less annoying. They're super slim so they don't add bulk or pressure points. Super important tip though - take them OFF before washing your headgear to keep the magnets from rusting. Just wipe clean with a damp cloth for daily maintenance. Comes as 4 pairs so you've got backups. Seriously, if you're tired of fumbling with your CPAP mask connections, these magnetic clips will make your life so much easier. They hold securely all night but disconnect in seconds when you need them to. One of those simple accessories that actually makes a huge difference in your CPAP experience.
