The only concern I have is the safety of the UV light and the amount of exposure you get by looking at it while it's working. If you're looking at the green light on the handle part, you're looking in the direction of the UV radiation. UV contributes to the development of cataracts and it doesn't seem like such a good idea to look at it while it's working. I don't remember how much UV radiation water actually filters out. Glass doesn't offer much protection, plastic a little more and acrylic a little more. Maybe the combination of the water and the plastic bottle reduces the exposure. The Hydro-Photon site doesn't say much about visual safety or protection. I guess not looking at it while it's working would be the best protection. I still think it's a cool way to purify drinking water. Hey this sounds cool and useful.
