Recent Water Treatment Product Reviews

MSR Guardian Purifier

rated 4.5 of 5 stars Great product and would recommend to everyone. With its ease of use, the MSR Guardian Purifier is great for all outdoor enthusiasts and survival preppers. The product produces crystal clear and very good pure tasting water. However, the filter can be difficult to dry and after a while of no use it can get a moldy smell. Full review

Sawyer MINI Water Filter

rated 4 of 5 stars Compact lightweight water filter, easy to use, drink on the go, great for when you are on a river or lake. Used this for two years so far, backpacking and river rafting. Bags last me about one year. Sorry, I didn't keep track of how many gallons I filtered, but I go out on overnighters every month with several weeklong trips throughout the year. I "upgraded" to the 32oz bags when the small ones wore out. One should always carry an extra bag just in case. It's also nice if you have a hike from camp… Full review

Platypus GravityWorks Filter System 4L

rated 5 of 5 stars Excellent filter, works fast. I have always purchased Cascade Designs (which Platypus is a part of) products whenever I can because of the excellent customer service and excellent products. They won't be the cheapest product around, but I have an MSR WhispeLite stove, BaseCamp pad, Vela HD quilt, and Platypus water filter. When I got this filter from Amazon it was missing the proprietary connection to one of the bags. I called Platypus on a Saturday and a very helpful (English speaking) person… Full review

Sawyer MINI Water Filter

rated 2 of 5 stars Worked well until the water pouch bursted. Then it became rather useless. When it worked, it worked really well. It takes some time to get your water, but this is a light and inexpensive system, so a tradeoff I was willing to make. Without a warning, my pouch bursted and I could no longer use the filter. This was after about 200 litres of filtered water. Full review

Katadyn Hiker PRO

rated 4.5 of 5 stars Easy to use water filter for backpacking. Have owned and used since 2013. Love this filter. Very easy to use, especially when utilizing quick-connects for water bladders. Take very little time to set up and filter. There are several options available (pens, gravity bags, etc), but this has always worked well for me. Very user friendly. My one recommendation and caution is removing and effectively cleaning/drying the filter inside the unit after use. I didn't do this once and got a moldy filter. Full review

Katadyn Hiker PRO

rated 4.5 of 5 stars Just bought this as a primary water filtration system. Used it last weekend as we were camping/hiking Jones Mtn in the Shenandoah. The spring was located right by the cabin we rented. Now I wanted this for the easy pump (47 pumps = 1 liter) and that was indeed easy—NO STRUGGLE or EFFORT needed to accomplish this. And if memory serves it was about 47 pumps. Lightweight for its size. Separate stowage bag and also one of the ziplock "sandwich" type bag for the dirty (OR CLEAN, depending on what you… Full review

Sawyer MINI Water Filter

rated 3 of 5 stars Taste and clarity are a plus for solo packing. The Mini Sawyer is all right for an individual solo packing to conserve weight and space. Simple to use. Filling up the provided bladder is challenging in seeps trying to refill a 3-liter bladder and Nalgene bottle. Typically this took over 30 minutes to replenish water storage. The bladder gave out at the seam making the filtering of water dependent on someone else's used 16oz bottle which the threads did not match. Back flush takes time and requires… Full review

Katadyn Hiker PRO

rated 4 of 5 stars It's great for filtering (not purifying) water and at a reasonable price. I have two of these. My first one, PUR brand I got around 1993 and used it for years in the Olympic mountains in Washington. In 2000, I used it when I re-walked Colin Fletcher's 1000 mile summer through California. That state had some funky water... and after seven years and gallons of water it gave up the ghost in Bridgeport, BUT.... The PUR CS people were GREAT. I told them they I was in the middle of the hike and they rushed… Full review

MSR Guardian Purifier

rated 5 of 5 stars The MSR Guardian water purifier is an amazing piece of kit. It pumps water in both directions which makes it fast and efficient. I really loved the new approach to getting the hose into the water, so that the intake of water comes from the top of the water source and not from the bottom of the lake like previous water filters. I used this filter during a multi-day canoe and hiking trip in the Yukon. The double pumping ability of this pump put the MSR Miniworks to shame and it became the go-to filter… Full review
