MSR Guardian Purifier

rated 5 of 5 stars Simply the best water filter in the world. I have used water filters for decades. My first one cracked when it froze. I have used two MSR MiniWorks with great results. It was great to be field repairable and field cleanable BUT filtering water was slow and required a lot of effort, usually at the end of a long hard day! Enter the MSR Guardian! Less than half the effort of the MiniWorks and at least twice the speed. For these two features alone this filter would be the winner but there is sooo much… Full review

MSR SweetWater Purifier System

rated 4 of 5 stars Have been using this water filter/purifier for 6 years while elk hunting. Had to use filter brush only at the beginning of each trip at home. I generally filtered 6 total liters of water at one time to avoid this duty daily. I really like the unit and always use the suction hose pre-filter. I have been using the MSR Sweetwater for 6 years while elk hunting. I always use the brush, at home before I leave for a hunt. Usually pre-filter 6 liters in camp right away, so I don't have to filter daily. Full review

CamelBak All Clear

rated 4.5 of 5 stars The product is very innovative and easy to use. The battery life is never a problem and this unit is utilized by two on the trail. Having a top with the filter gives the best of both worlds with UV and filtration. Nice to have the solution from one company. This unit make very quick work of hydration. Fill the bottle, hit the button, and then shake gently for a short time. How easy is that? I can purify the water and change heads in under 2 minutes. It sure beats having to squeeze through a filter… Full review

MSR Guardian Purifier

rated 5 of 5 stars The MSR Guardian is small, lightweight, and pumps fast. To catch the output, you can either attach the hose from your bladder or screw a container (with the correct threading) on the bottom. Very well built. The handle doesn't flex at all while pumping. Would definitely recommend for adventurers who engage in multiple-day hikes. My search for a portable water filter started when I got tired of hauling my water thus limiting the number of days I could hike at a time. I did a lot of research and comparisons… Full review

Platypus Meta Bottle + Microfilter

rated 4 of 5 stars A quick easy water filtration bottle. Scoop and drink treated water directly from the bottle or squeeze water through the filter into another vessel. When I first received the Platypus Meta bottle with Microfilter I thought it was just another filtered water bottle. Well, I was wrong, as it has become my go-to water treatment device for hiking and backpacking. Platypus took its already popular Meta soft bottle and added a removable micro-filter to the top that allows me to drink directly from… Full review

MSR SweetWater Purifier System

rated 5 of 5 stars Solid performer. After using the old porcelain Katydin filters of the '80s, this SweetWater was revolutionary. You could actually fill a poly bottle in a reasonable amount of time, and it is lightweight. I bought my first one in the '90s and we are on our second cartridge and just replaced the yellowed tubes last year, on the second pump. We usually put a pan in the stream and let the water run over the edge, that way you don't suck up the particles that plug the cartridge up. If it spits water… Full review

MSR Guardian Purifier

rated 4.5 of 5 stars The MSR Guardian is a top of the line water purification system that delivers on its impressive claims. Very fast, very efficient, and largely hassle-free (requires no backflushing). Excellent for the solo hiker, but perfect for larger groups. Disclaimer: This review is purely on design, usability, durability, and my overall opinion of the product. Without access to a water testing laboratory, I cannot make any claims regarding the actual efficacy for removing harmful impurities (biological and… Full review

Grayl Quest

rated 3 of 5 stars I Love the concept! I just question how well it works. It says to just push down on cartridge and once it reaches the bottom water is purified. It says it should take 30-60 seconds to push down. When I tried it went down very quickly. I was afraid to actually bring it to Nicaragua with me and try it. I really wanted this to work for me. The Grayl Quest Purifier is an all-in-one system. The system itself claims to last over 10 years. I felt like the pressure I was applying wasn't enough to prove… Full review

First Need Deluxe Water Purifier

rated 5 of 5 stars Reliable, versatile, and fast. Reliable, versatile, and fast. I purchased my unit well over 20 years ago. Used it on hikes in the Coast and Cascades ranges of Oregon and Washington. And really put it to the test while while trekking in Myanmar, Central America, and travels from Ghana to Namibia. Purified water from very suspect sources. Never had an issue, never suffered from water borne problems. Definitely a lifesaver and definitely a product to recommend.  Full review
