Will Lumin damage my CPAP mask or accessories?

No. While long exposure times to UVC can weaken plastics and silicone, the Lumin cycle time is only 5 minutes. One year of daily use amounts to 30 hours of actual exposure time. In accelerated aging tests, 3B has validated no damage to plastics or silicone in over 150 hours of testing, roughly equivalent to 5 years of daily use.
