Yes as the whole point of the uv lamp is to kill bugs on your molds and to help stop infections.
Some people don't use there dry and store every night. I honestly don't understand why not. It's great for storing them in there and the tablets will run out in 2 months no matter what and if you use it every night, then you will have less problems.
I've read somewhere that one person only uses the dry and store when they start to notice problems with their aids. The whole point is to use it everynight and then you won't ever (fingers crossed) have a problem with your aids.
I'm worn aids all my life (25 y), 13 years using some sort of dry box and I've nevered needed a repair on any of my aids.
