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

Grayl Ultralight

rated 5 of 5 stars Convenient, lightweight, perfect for short trips. For short trips this thing is perfect! If you're going to be out for a week or less this will suffice so long as there is a freshwater source in the vicinity. Super easy and fast to use. Great for on the go! Used it while in an endurance race down a river in Florida for two days. Worked perfectly! It now replaces my Berkey sport bottle. Full review

Katadyn Exstream/MyBottle Virustat Kit

rated 5 of 5 stars Great filter. Only imparts a slight iodine taste. I've used this setup for a few years to filter water on hikes up to a week long. I have filtered water from disgusting cow ponds and have never gotten sick. The flow rate is on the slow side, but it's a small price to pay for a great filtration system. This kit gives me enough confidence to drink water from pretty much any source if necessary. I find that the slow flow rate actually makes me drink more often and keep hydrated as opposed to chugging… 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

Sawyer Select S1

rated 4.5 of 5 stars Great product. Easy to use and serves as a lightweight purification method. Wow, what an easy to use and effective lightweight water purification method. Great for the individual for backpacking and hiking. Full review

Sawyer MINI

rated 5 of 5 stars The go-to for almost any backpacking trip or emergency preparedness. Easy to use, inexpensive, and easy to find stores that sell these. We always bring our on overnight trips, but it's lightweight enough to bring on day trips for emergencies. I have recommended this to a few friends already. We used for a multi-day trip with four people, but I would recommend the regular sized Sawyer if you have more people or faster water flow. Full review

Bota of Boulder Outback Water Filtration System

rated 5 of 5 stars The water bottle itself works pretty well, but throw in a good filter, and you have yourself a great, lightweight water bottle/filter for use in the backcountry. I purchased one of these bottles back in the late 1990s. I don't remember for sure if it was the Bota brand, or not, but I do know that it is the same drop-in cartridge filter and has worked wonderfully. I'veĀ used it on multiple backpacking trips with friends over the years. A couple of my friends were so impressed by it, that they went… 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

MSR MiniWorks EX

rated 2 of 5 stars Disappointingly slow, even after cleaning the filter. Okay for a soloist, but definitely too slow to be used by groups greater than two people. It is easy to clean, and the water comes out clear and without bad tastes. I researched water filters for quite a while, and must have just over-thought it all, and ended up overall pretty disappointed with the MSR MiniWorks EX. I really liked the idea of a ceramic filter that was easy to clean and wouldn't need to be replaced for a long time. So, ultimately… Full review
