Another innovative offering from MSR, the TrailShot Microfilter weighs just 5.4 ounces, has a flow rate of 1 liter per minute, and effectively treats up to 2,000 liters of water. Perfect for backpacking, the filter is effective against bacteria, protozoa, and particulates.
The filter utilizes Hollow Fiber Technology to maximize flow rate while also effectively neutralizing all but the most microscopic threats (NOTE: it is not effective against viruses). A simple squeeze action draws water from the nearest available water source through an integrated hose, and passes water through the filter, allowing you to drink safely immediately and directly from the integrated nozzle of the TrailShot. The field maintainable filter is incredibly easy to clean and requires no tools. Should you use the filter frequently enough to have treated 2,000 liters, the TrailShot Replacement Filter Cartridge (sold separately) is available to fully restore the filter’s effectiveness.
The full dimensions of the MSR TrailShot Microfilter are 6” x 2.4”, allowing it to stash conveniently in your backpack.

- Quick water

Likes: Fast flow, pre-filter doesn't clog easily, lightweight and fits in front pocket of my UD vest. Quick and easy to deploy and use.
