First Need Deluxe Water Purifier

rated 5 of 5 stars The only real choice if you want to remove all the nasty bugs/chemicals from your water source with a single self-contained device. I’ve had this First Need purifier for nearly a decade and it has served me and my hiking/backpacking buddies well.  Most importantly, this is not simply a water filter but a chemical-free purifier.  That means you don’t have use the chemicals other require or the addition of iodine make water safe to consume.  This means it removes a lot of those difficult to… Full review

SteriPEN Classic

rated 5 of 5 stars Best device for the money. Had it for four years now and it's never failed me. Even when I dropped it and the battery cover cracked, it still worked. Great piece of kit, never go off into unsafe waters without one. I've had the Steripen Classic for four years now and it's never failed me.  Even when I dropped it and the battery cover cracked, it still worked. To boot, when I called SteriPEN for information on how to repair the cracked cover they simply shipped a replacement battery cover to me… Full review

MSR SweetWater Purifier System

rated 4.5 of 5 stars I have used the SweetWater for three years now. It has always done a great job. When an internal mechanism broke from years of use, MSR promptly replaced it—no questions asked. I got it used. When handed to me, I asked the guy how much life was left in it. He said he thought it was at the end of the line. I used it for two more years. It's finally starting to "pop the hose back" from the filter being at the end of the line. Effectiveness: Treats water well. Be mindful that it takes out particulate… Full review

SteriPEN Adventurer Opti

rated 4.5 of 5 stars Have utilized the SteriPEN Aventurer Opti now on several outings this summer instead of my pump water filter systems and found it to be very simple and effective. On previous trips (before the SteriPEN), after a rain, the rivers and streams would be full of silt and dirt. That fine silt clogged my pump filtration systems. I tried different pump systems. I replaced filters. I backwashed the units. I found that back washing the unit once for every liter of water, no matter what pump system I was using,… Full review

SteriPEN Adventurer Opti

rated 4 of 5 stars I have this and love it. I love it; it works well. But like any new gadget it does take a few times to get the hang of it. Granted the cost of the battery is a little pricey, but you should be able to use it a year on a set of batteries. So that's not really a big deal, not like I would ever use 6,000 gallons of water hiking in a year. It's a good packable size. I bought this because most methods of water purification is just awful tasting and the the thought of me drinking bleach water is just… Full review

MSR SweetWater Purifier System

rated 5 of 5 stars Great little pump. I've had mine must be almost 10 years or pretty close. Bought the system when they first came out, used in all four seasons, used it to get water from a streams, lakes, through the ice. Works really well. Replacement filter is a little pricey, and it doesn't pump the volume of the newer ones ,or as fast. But I just don't have the heart to replace it. It works so well and the Sweetwater purifier solution that comes with it makes the water taste like the water that comes out of… Full review

SteriPEN Classic

rated 4.5 of 5 stars I got this three summers ago after going on a backpacking trip with a buddy who had one. I really like the convenience and the quickness on how it works. Here in CO most of the mountain streams we come across run clear so we are not dealing with murky, dirty water. The included filter works well to block the bigger stuff. I've put three years of use on the Classic model and to date, have had zero issues with it. I buy the lithium ion batteries for it and the last set made it through the complete… Full review

SteriPEN Sidewinder

rated 3.5 of 5 stars Works well but is better suited for base camp or cabin use rather than backpacking. This is my third Steripen, I also use an Adventurer and a Classic. I originally bought this because it did not require any batteries  which would be one less thing to worry about. As far as basic operation goes they all work the same. I got this Sidewinder about 6 months ago and in that time I have had no issues or problems with it at all. It works just as the manufacturer says and since I have not acquired any… Full review

SteriPEN Traveler

rated 4 of 5 stars This water purifying source is very easy to use. It is very small and lightweight for backpacking trips. I recommend a backup treatment option of some kind in case you run into battery or workmanship issues. At right around $50 it is very affordable. My friend had a SteriPen Classic and the quick, easy treatment of the water with the UV light was very impressive. I found this smaller, lighter model and purchased it instead.  It provided about 400 treatments before I had issues with it (the light… Full review
