Yes, it seems that this product would work in killing germs, so that's a positive.

But, doesn't UV-C light also damage human skin? As far as I'm aware, it's the most damaging light which can cause skin cancer!

I'm not sure on exposure strength from this unit, or how damaging it actually is, because surely they've tested this thoroughly and wouldn't be able to sell it if it wasn't safe. But for me, I don't think it's a risk worth taking for "a fresher room". I'm not trying to create a sterile environment in my home.

Interesting product, and for those a little OCD about germs, it might be a killer product...good hunting!
