Recent Pump/Gravity Water Filter Reviews

Katadyn Gravity BeFree 3.0L

rated 5 of 5 stars I wanted a filtration system that was easier to use than the Sawyer. I found it. This system is super fast and easy. I used it on a weekend backpacking trip on the Appalachian Trail and could not be more pleased with it. While the filter doesn't filter as much water as the Sawyer (you can filter about 1,000 liters before you need to replace the filter), the trade out is there is no backflushing necessary and it's much faster to fill the reservoir because the opening is bigger than the Sawyer (43… Full review

Renogy Portable Outdoor Water Filter

rated 2.5 of 5 stars It is a functional pump that works, but isn't all the easy to use, especially by yourself. There are better filters out there...I'd recommend Sawyer. It is a functional pump that works, but isn't all the easy to use, especially by yourself. I found that having at least one person to assist by holding the clean water bottle and to make sure the water inlet hose stays in place. It went even better with three people. Unfortunately for me, this isn't great. Overall, a functional filter that works as… Full review

LifeStraw Mission Gravity Water Purifier

rated 4 of 5 stars The gravity filter allows you to do other things during filtration, instead of pumping. No need to stand by the river to filter. You can carry the water back to camp. I agree with other reviewer about potential cross contamination during storage. Thanks to the other reviewer for the review, very detailed indeed and very accurate.  I used the filter for a two-month bike trip in Namibia and  Zambia, almost exclusively in clear water sources. I agree with your concerns about cross contamination during… Full review

Renogy Portable Outdoor Water Filter

rated 5 of 5 stars Easy to use, compact filter. As a member of another website, I occasionally receive free gear to demo in the field while camping in exchange for a review. Hiking the Grand Teton was the perfect opportunity to put the Renogy Tactical Water Microfilter to the test. This trek was taxing and I consumed a lot of water to keep hydrated. The Renogy water filter is compact and super easy to put together and use quickly. There is a silicon tube that attached to each end of the device. There is a float… Full review

Katadyn Pocket

rated 5 of 5 stars This baby is durable. Easy to maintain. I've had this filter since 1987 or 1988 and it is still going like a champ. Mostly I backpack in the western Sierras and have done Glacier National Park. Not once have I gotten ill and this filter is still going strong. Mine is the older model with the white plastic casing and I expect it to last until I can't lift a backpack. It is a little heavy for a filter, but when I purchased it, I wanted a filter that would last. Even the original O-rings that came… Full review

Renogy Portable Outdoor Water Filter

rated 4.5 of 5 stars Works well Small, packable, compact Easy assembly Easy care As a member of another website, I sometimes get the opportunity to try out different products in exchange for a review. I received the Renogy Water Filtration System to review and abuse on my recent camping trip. The Renogy Water Filtration system fit easily in my hydration bag. Easy initial assembly and basically three parts to pack. I would suggest pre-assembly due to a few small parts. Then main assembly when you pull it out to use it. Full review

Renogy Portable Outdoor Water Filter

rated 4.5 of 5 stars Sometimes I get the chance to review products in exchange for an honest review. This time, I got one of these filters to take with me on my Appalachian Trail hike, and it worked really well. Not hard to figure out and does what it's supposed to, as long as you follow the directions. Great for backwoods/water/streams etc for filtering water so that it's drinkable. Even if it's slightly dirty. As the member of another website, occasionally, I have the amazing opportunity to test awesome products in… Full review

Sawyer Squeeze

rated 4 of 5 stars I have used this on overnight backpacking and bikepacking trips, as well as big one-day loop hikes. It is fast filtering, and with a little practice/modification, you can get water from almost any source. This filter is fast, and can provide water for a group as the only filter. The most important thing to note is that the pouch is very challenging to fill, especially in moving/very cold water (sticking your hands in alpine streams can be frigid). The best way to solve this is taking a 1G ziplock… Full review

Katadyn Hiker

rated 5 of 5 stars On our second filter replacement, but this Katadyn (PUR) Hiker pump is still going strong after more than 20 years and dozens of trips. This filter just works! No fuss, it just keeps ticking. After dozens of multi-day backpacking trips in the mountains of central Idaho, it finally started to slow down a bit to the point that the input hose would crimp at the point of entry into the filter body. So, we replaced the filter and lubed the seals and plunger, and it felt like new and just kept on chugging. Full review
