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

Aquamira Water Treatment Drops

rated 5 of 5 stars “I choose a lazy person to do a hard job. Because a lazy person will find an easy way to do it.” Aquamira drops have been my go-to for water treatment for a few years now. I've used a Katadyn Basecamp gravity filter, which worked well until it just stopped one day. Pretty big and heavy in retrospect anyway. I've also used a gravity filter that I rigged up with a Platypus Big-Zip and a Sawyer Mini that worked brilliantly until it just stopped working one day no matter how hard I back-flushed… Full review

Katadyn Vario Microfilter

rated 3.5 of 5 stars Great for group trips. This is a big monster of a pump that is great for pumping super clean water fast.   Effectiveness I've always used the pump in the long life setting which involves both filter functions, the ceramic disk prefilter and the pleated glassfiber filter. The faster flow setting disengages the ceramic prefilter. The pump also has a carbon filter to make the water taste better, which is one of my favorite features. Neither myself or anyone who has used the filter has ever been sick. Full review

Katadyn Pocket

rated 5 of 5 stars Expedition bomb proof filter. Easily handled our family of four when hiking in summer across Isle Royale for a week and had to filter all water from the lake (don't drink the untreated water!). The only filter I would carry in the back country. Full review
