One thing that I've been needing in my camping equipment is a quality water filter, but ya know. poor college student, I can't really afford one right now, so Ive been borrowing a few from friends and neighbores when I go on my adventures.
The first on that I've tried out is just the regular pump filter. I like them, they work really well (as far as I can tell, I haven't gotten sick yet), they do weigh a bit more than I'd like and they're kinda large, but hey when it comes to purifying water, I'm not sure how cheap you want to go. some bad water in a bad situation could very well be the death of you. it's a pretty simple setup. One hose goes into the stream or wherever you're bringing the water from, and the other hose goes over the top of your waterbottle. and all you have to do is pump. all in all, i'm pretty pleased with the pump filters. I've tried a few different brands. they're all pretty much the same, and easy to use.
The next type of filter is one that I can actually afford, and it's the straw filter. these are really nice because they are super small and super lightweight. the concept is basically a simple straw that sticks into a small filtering device (see image) and than you basically just suck on it, and it filters it as it goes into your mouth. The one that I use is called a Frontier Emergency Water Filter System. there is enough filter on it to purify thirty gallons of water. I was a bit leery at first about using this because it was so small, but I trusted it, and have drank from some pretty questionable water, and I'm still around to tell the tale. All in all, it's a great little product, and only about 8 bucks at your local sportsmans store. lightweight, small, and simple to use.
Another method that I just discovered the Steripen. This little guy is actually quite amazing. it purifies water with UV rays. I did a whole bunch of research on them, and went to the local sportsman’s store and took a look at all of the different filters, and one of the workers came up and started talking to me, and I asked him about them. He had tried a number of different water filters and really liked the Steripen, the only bad thing about it was that it took batteries, and since it gives out UV rays, it drains batteries pretty quickly. That is a downside, but I also saw that they make carrying cases for the pen that is also a solar power charger. Man I covet this so bad. I've been looking for something like this, and it will continue to work for as long as I have sunlight. I haven't been able to try one out myself yet, but someday I'll get one. If any of you that are reading this have had experience with using one of these, please post a comment and let me know what you think about it. I'd love to know.
Other methods include Iodine or chlorine tablets. These are great little pills to put in the water that makes it safer than ever to drink, they're extremely light weight, and take up almost no space, the only thing is that it gives the water a bad taste. If you use this method, I would recomend also bringing some sort of powdered drink mix. This way, it'll take away that bitter flavor. it doesn't have to be a ton, just enough to mask the taste of the pills. This isn't my favorite method, just because of that. I like drinking water. not water that's been treated and a hint of lemonade has been dropped in.
By far the most timeless and foolproof method of purifying water is boiling. it will kill all of the bacteria in any water, thus making it drinkable. the downsides of boiling your water is that once it's purified, it's too hot to drink, and you have to wait for it to cool before drinking, and you need some way of boiling it. A source of heat, and something to boil it in. Recently there has been a lot of contravercy over how long you need to boil your water before it's purified. Some people say two minutes, some say five, ten, even twenty. But according to the Wilderness medical society, it only needs to be at a boil for zero minutes. once it's reached the point of boiling, all of the bad stuff has been killed off. If you don't believe me, I urge you to research the topic out, and get back to me.
