The Trailshot Microfilter from MSR makes it easy to get water without slowing you down. This smart solution will follow you on all your adventures.
Drinking water all day, featherweight version. That's the strength of the TrailShot microfilter. It's designed to fit easily into any nook and cranny, and always be at hand. This microfilter allows you to filter water directly from watering holes along the trail, ensuring instant hydration and filling your water bottle or water pouch with drinking water. Easy to use with one hand, it filters a liter of water in a single minute, so you can get back on the trail quickly. Weighing only 5 oz (142 g), the TrailShot Water Filter is the perfect filter for adventurers looking to cover the most distance as quickly as possible, or trail runners, hikers, fast hikers and mountain bikers.


  • Performance: meets the U.S. Environmental Protection Agency (EPA)* standards for clean drinking water and NSF P231 protocol for bacteria (99.9999%), protozoa (99.9%) and particulate removal.
  • Pocket size & lightweight: This 5 oz. microfilter fits with mini-bottles, mini-bike pumps and spare tubes in any tote bag.
  • Instant hydration: You can drink directly from the water source - without having to lie down in the mud - and refill your water bottle or water bag whenever you want.
  • Quick to use: nothing to assemble, it is simple to use, with one hand, and allows you to fill a 1 liter water bottle in 60 seconds.
  • Easy to clean: just shake the filter to restore the flow in the field; no tools are required.
