If you’re out camping, the SteriPEN might not be the best water purifying solution, but it sure is nice to have it in your pack if you haven’t got anything else. It can basically replace a Brita filter and help deal with some contaminants, ensuring that the water you are about to drink is clean.
The new SteriPEN Freedom is charged up with USB power and relies on UV rays to purify water. It’s also a lot more compact than a Brita filter or filtration device, but then again it doesn’t actually filter contaminants. However, in under a minute, after you’ve stuck it into a glass of water, it will have killed off 99.9% of the nasty bacteria, viruses and protozoa hanging out in the water. This makes it quite convenient, especially if you’re stuck in the outdoors.
The Steripen sells for $120(USD) and it’s available right now.
