Fitted UVC Light-Blocking Cover for CSpring MK3 and MK2

That soft glow coming from your water chamber might be doing your CPAP water good, but it's probably not helping you get quality sleep. The CSpring's internal UVC LED is there to keep your humidifier water sanitized, yet in a dark bedroom, that same light can be enough to keep you, or whoever's next to you, from actually falling asleep.

This cover was built to fix exactly that. Pull it over your Cspring MK3 or MK2 and it immediately shuts out every bit of visible light, while leaving the sanitation cycle completely untouched underneath. The device keeps working exactly as designed; your room just stays dark the way it's supposed to. It's a small fix for a complaint a lot of CSpring owners run into, particularly people who need total darkness to sleep or who share a bed with a non-CPAP partner.

The tightly woven fabric also acts as an everyday shield against dust, pet hair, and general buildup when your device is sitting out. And because it's a simple slide-on fit, there's no fumbling with straps or adjustments, simply cover it and you're done.

Key Features and Benefits

• Blocks 100% of Visible UVC Glow: Fully encloses the sanitizing LED so no light escapes, even in a pitch-black room.
• Sanitation Cycle Runs Uninterrupted: The cover doesn't block airflow or disable the device, allowing your water chamber keeps sanitizing normally underneath.
• Durable, Fray-Resistant Fabric: Built from a tough, low-stretch material designed to hold its shape and light-blocking ability through nightly use.
• No-Strap, Slide-On Fit: Contoured specifically for MK3 and MK2 shapes. No fasteners, Velcro, or adjustment needed.
• Dust & Debris Protection: Adds a protective barrier against household dust and lint when the device sits out on a nightstand or shelf.
• Better for Shared Bedrooms: Reduces light disturbance for partners who aren't using the CPAP system themselves.
• Easy Care: Hand wash or wipe down with a dry cloth — no special maintenance routine required.
