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

Katadyn Hiker PRO

rated 5 of 5 stars It's hard to look at water filtration as anything but a chore. At least it can be less of one. There will be advocates that stump for total protection, who want a purifier. There will be those who do nothing at all and drink the water straight. Since I personally know more than 30 people who've had confirmed giardia cases that were actually a result of wilderness water sources, I have a few different kinds of filter for different kinds of trips. When taking a group and sharing my filter, I bring… Full review

Katadyn Vario Microfilter

rated 5 of 5 stars A great filter for filtering water for groups of people or for just getting out large volumes of filtered water fast. I've put a countless amount of gallons through this filter and have seen no drop in performance so far. To put an approx. number, I've probably put at least 100 Liters through this thing and no problems of failures have occurred so far. Couldn't be more happy with a filter like this. I use my filter on longer life most of the time, I don't see a true need to get water out as fast… Full review

Katadyn BeFree

rated 5 of 5 stars Small, compact and easy to use. This filter is also fast and can be backwashed to clean out the filter. I used this filter while section hiking 500 miles of the AT. I could filter a half liter of water in seconds into another bottle or bag but also drink straight from the BeFree. It stores in the side of my pack. You just roll it up when not using so it's small and lightweight. It only weighs 2 oz. I never had problems with durability. It was great when the stream was low or slow moving because… Full review

Katadyn Combi

rated 5 of 5 stars Great working, long lasting, but heavy. This thing is rated for 50,000l like wow. It is smooth and sort of one piece with the hose detached. In my opinion it makes it unlikely to break. I've had this for like 15 years. It has been used thousands of times, all over the place, in all climates. With the charcoal full the water tastes fresh and crisp like bottled water from the store. Charcoal takes out pesticides as well.  It is heavy compared to tablets and other smaller ultralight filters. We will… Full review

Sawyer Cleaning Coupling

rated 4.5 of 5 stars A simple and brilliant accessory for the Sawyer Squeeze filter that allows one to improve back-flushing success with a device that is smaller and weighs less than the syringe provided for this purpose with this filter. At a price just south of USD $9, it's doubtless overpriced but still well worth it for any Squeeze users. Background Sometimes less is more, and sometimes experience allows one to "smooth it" in the woods, to borrow a phrase from nineteenth century outdoorsman and conservationist… Full review
