If you are frequently on the road or in the air, you may be forced to buy bottled water, as some tap water sources can be a bit questionable. Normally, this is only a problem found in a few foreign countries, but it’s likely better to play it safe than sorry. Buying individual filters can be a pain, so why not purchase something that is going to keep producing the same quality without having to wonder if it needs a replacement?

Some hospital instruments are sanitized with UV-A and UV-C light. This type of lighting is used in the Portable Water and Surface Sanitizer, and it has the ability to purify 2 cups of water in forty seconds. Now, this light doesn’t just destroy regular germs, it annihilates the DNA of extremely dangerous microorganisms such as E. coli, Staphylococcus, and Salmonella as well. It comes equipped with a built-in LCD screen that will give you a countdown to an “OK” signal regarding how long you need to keep sanitizing your water or surface. Costing only $100, and needing only a few AAA batteries to function, I’d say this is a decent buy.
