MSR Trail Base Water Filter Kit
When it comes to water filtration systems there are a myriad of different ways to get your water clean. By clean, I mean the actual filtering of dirt and debris as well as filtering water on a microbial level. I’m here to announce I have found the most effective gravity and portable trail water filter I have ever used.
A little of the technical stuff:
- Filters 99.9999% Bacteria
- Filters 99.9% Protozoa including Giardia and Cryptosporidia
- Filters Particulate
- Hollow fiber filter meets U.S. EPA drinking water standards* and NSF protocol P231 testing standard.
- Not a Purifier – Doesn’t filter all viruses
Filter: Hollow Fiber
Flow L/min: 1liter per min claimed
Flow Strokes per liter: 60 pumps
Field Maintainable: Yes
Field Cleanable: Yes
Cartridge Replacement Indicator: Yes
The portable Trail Filter shoots water about 8ft when new, it has serious water pressure!

I have used a myriad of different water filters from some the industries top companies. This system is by far the fastest gravity AND handheld system I have ever used. At one point during the testing process while mountain biking far in the backcountry, I could feel myself starting to bonk due to dehydration. I know my body well enough to know that I needed water in abundance and quickly! I pulled the bike over and found a stream, stuck the portable TrailShot end into the water and started to fill my bottles. In a matter minutes I had chugged 2 – 21oz bottles and refilled them again to keep on the bike for later.
When your body starts to bonk the use of a filtering system can seem a bit daunting, this system took out all the guesswork and just simply did its job. What more can you ask for?
