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

Platypus GravityWorks Filter System 4L

Perfect for individual or small group use in BWCAW. I've now used this filter system for two BWCAW trips, two nights in August and five nights in October. The August trip taught me the necessity of taking care when collecting water, to avoid clogging the filter. In October I had zero issues, partly because I took care to rinse out the dirty water bag each time before refilling it. I didn't need to do any back flushing in five nights/six days. 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

Katadyn Hiker

A good alternative to treatment pills. I have used the older PUR version of this filter for the past 20+ years to purify all our drinking and cooking water each hiking day. Find a flowing water source if possible, they say 20 feet of tumbling water is somewhat clean. I would not expect this filter to clean water from a stagnant pond that horses use.  I have tried treatment pills, but don't like the idea. I cover the inlet filter screen with a double paper coffee filter held in place by a rubber… Full review

MSR Miox

Amazingly light, and extremely effective purification. I have used this for over 12 years and NEVER had an issue with it ! I have used this device for over 12 years; and in guiding groups of up to six people, I have NEVER had anyone suffer any stomach ailments or discomfort. Ever! But I do not use it the way the manual suggests. By using dirty murky water in the purification reservoir,  I found that friends' MIOX devices eventually corroded the electrodes and rendered them unusable. Instead, what… Full review

HydroBlu Go Flow Water Gravity Bag with Versa Flow Water Filter

Hydroblu's Go Flow Water Gravity Bag with the Versa Flow Filter is a lightweight, efficient way to filter for a group of people. Comparable to the Sawyer Mini, the Versa has an impressive flow rate. Water filtration can be tricky to navigate. Factors like external temperature, filter flow rate, and weight might go into your choice. If you're into ultralight backpacking, chances are that you've owned a Sawyer Squeeze or a Mini. But the birth of Hydroblu's Versa Flow Filter has me intrigued. Offering… Full review

SteriPEN Adventurer

Unlike mechanical filters this kills bacteria, protozoa and viruses, but it will not filter out debris, so it is best used with clear water. Also requires batteries. I have used the Steripien Adventurer for several mountain trips where I was guaranteed running water. I was attracted to it because, unlike other means of filtration, it also kills viruses. The idea is simple but genius—UV light disrupts the DNA of the nasties and destroys them and/or disrupts their reproductive potential. That said,… Full review
