MSR Thru-Link

The MSR Thru-Link inline filter is a two-stage water filter design that MSR has been providing to the U.S. military for more than a decade; it will be available to the consumer market in spring 2020. The filter is unique in that it is configured to be used in-line with a reservoir/bladder that can be filled with unfiltered water on the go and then your water is filtered as you go along on your hike. In use, the Thru-Link Filter works well and has good flow, but depending on how you stow your bladder… Full review

Katadyn BeFree 0.6L

This filter has been a literal lifesaver on my adventures. Its ease of use and modular bottle system allows it to adapt to various needs. Its flow-rate is top notch. I have been using this filtration system for over a year now. Although I have replaced the original filter cartridge due to the slowed flow-rate, it still technically works. Recently, I used this filter for all of my water over five weeks in Nepal. The Khumbu (Everest Region) is beautiful, but the water quality is very poor (many contaminants). Full review

HydroBlu Versa Flow

Lightweight water filter. This 2oz filter employs hollow fiber tubes with thousands of tiny holes (0.1 microns) that block 99.9999% of harmful bacteria, Giardia, E. coli, protozoan cysts, Cryptosporidium and more. Unlike other filters, which filter through their core, the VersaFlow filters water through the outside of these tubes by bending the hollow fiber. This dramatically increases the surface area and flow rate of the filter while protecting the filter integrity itself. I've not yet experienced… Full review

LifeSaver Liberty

Water purifier that does it all, even on an easy Sunday morning hike in the forest! "Found a picture in my phone, my daughter made a picture of me, from my best side, using the filter in a stream on a sunday morning, filling the filter with the hose." My first review ever, and in English, so I hope you can read/understand this. I cannot say that I am the most active outdoor person in my country, just consider myself as an outdoor enthousiast. Like walking, hiking with the family on a Sunday or on… Full review

Sawyer MINI

Compact, lightweight, and efficient. A perfect companion for the trail. You'll never know that it is in your pack. This is a great filter for backpackers, day hikers, and even those taking to the trail for an extended time. I felt perfectly confident with every use. It clearly worked well as I had no negative effects drinking from lakes, streams, and ponds. This little filter is so small and light you'll never know that it is there. Easy to use and easy to maintain. This is my go-to filter far any… Full review

LifeStraw Original

The LifeStraw is incredible. It makes drinking on the trail super easy. The LifeStraw is great! I love taking this with me on day hikes and especially when I’m backpacking. It’s super lightweight and doesn’t take up much space at all. At first the material of the LifeStraw concerned me. It didn’t feel like it’d be the best quality. But it has held up fantastic! It‘s good quality plastic. It’s just really lightweight! The instructions are simple. Uncap both ends, place the wide end… Full review

Sawyer MINI

Light, handy, and reliable. Out of several water filters I have and use, this one is the most convenient and sees the most adventures. We have three of these Sawyer Minis in our family. They work really well and are lightweight and easy to use. They connect to a variety of bottles and bags as long as the screw top/threads match up. Fill the bottle and screw on the Sawyer. Then either squeeze the water into another container or drink right from the filter. Doesn't get much easier. Get creative and… Full review

LifeStraw Go

I used this when i was out there for three days. No issues, as long as I found water to fill it! Never got sick, although it didn't make the clean water all taste awesome. It works, stayed in one piece well, sealed well, didn't shatter when I fell on it. Full review
