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

Sawyer MINI Water Filter

rated 4 of 5 stars This is a very light water filter with adequate flow if you're focused on minimizing the base weight of your pack. I have been focused on getting the base weight of my pack down under 20 pounds and one of the changes I made was going from a pump type water filter to the Sawyer Mini water filter. In general I am happy with the Sawyer Mini in that it does the job and only weighs in at about 2 oz. The filter comes as a kit and includes a syringe for washing the filter using a back flow, a 16 oz squeeze… Full review

Sawyer MINI Water Filter

rated 5 of 5 stars Best water filter I've ever had! Lightweight, small, durable, easy to use, and best of all it's very affordable. This is the perfect water filter for 1-2 people who are weight/space conscious backpackers. This is hands-down the best water filter I've ever owned. I could have skipped listing all of the pros and just said there isn't anything better on the market if you're looking for a filter like this. You will NOT regret this purchase if you're a backpacker that travels more than 100 yards from… Full review

Katadyn Base Camp

rated 5 of 5 stars Excellent filter for floating rivers in Alaska. I've been using the Katadyn Base Camp gravity filter for almost 20 years in Alaska. It works great as long as the water source is near camp...floating rivers or backpacking near alpine streams.   Since it is a gravity system, above timberline I set it up in the rocks on a steep slope and stretch the outlet line as much as possible downhill to maximize the flow rate. I clean the filter after each trip by removing the prefilter screen, soaking in soapy… Full review

MSR Autoflow Gravity Filter

rated 4 of 5 stars Great piece of kit... well worth the money. STOP PUMPING!!! I purchased this in the spring of 2016 for a 35-mile group hike (12 people) into the South San Juan Wilderness in Colorado. I was unsure if this would be able to keep up with that many people's needs, but after the second day I knew it was well worth the cost. The Autoflow easily filters water fast and in large amounts. I actually watched some other hikers from not in the group stop pumping their own water and ask to use it! It is so simple. 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

Sawyer MINI Water Filter

rated 5 of 5 stars Saved a three-week trip on the John Muir Trail. Brought as a backup, used as the main filter for two people. So we took off for a three-week leisurely llama trip on the John Muir Trail (National Forest section)...just goofing off and doing lots of fishing. Five llamas for carrying power and two dogs for company, entertainment, and a heat source for the tents. Most of the hikers on the JMT are pounding out miles everyday and miss the solitude and spectacular beauty of side trips off the main trail...not… 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
