Description

Helps keep viruses, bacteria, and germs from building up in your Cpap tank while blocking direct UVC light to your eyes. Doesn't clip on or attach directly to Cpap just slides over the tank while sitting on a flat tabletop. I have it on a timer to come on 4 times a day evenly spaced for 5 minutes each time (every 6 hours). 

**Important! Read ALL Below**

**Follow safety guidelines for UV-C products. Don't look directly at light.

**Follow your usual cleaning processes for tank, hose, and headpiece. Im not worried about voiding my warranty or anything but you use it at your discretion.  I'm not responsible for modifications to medical devices, or careless operation- use at your own risk. 

That being said, It works great for me. Noticeable difference when it comes to keeping the tank clean.  The backplate is a wedge to aim the UV light slightly downward.

Parts needed:

  • Pick up 2 UV bolts from Amazon (see last photo) 
  • 2 M3x4 screws. Threads directly into plastic back piece. Don't need any torque- just enough to attach- otherwise you can drill through and put a nut on it. 
  •  You'll also need a 12v power supply and connect in parallel.

Print in black for less light bleed, 4 perimeters, PETG, ABS, or ASA. I printed mine in PETG.

I put these UVC lights in my Ice machine and noticed some plastic discoloration after a couple years, but haven't noticed any changes to my Cpap since I have been using these for a couple years now.
