The MSR TrailShot Microfilter is a compact and lightweight water treatment device designed for outdoor enthusiasts and adventurers. It is specifically designed to provide on-the-go filtration for drinking water from various sources such as streams, rivers, and lakes. Here's a description of the MSR TrailShot Microfilter and its features:

  1. Portability: The TrailShot Microfilter is incredibly portable, weighing just 5.4 ounces (153 grams) and measuring approximately 6 inches (15.2 cm) in length. Its compact size allows for easy storage in a backpack or pocket, making it convenient for hikers, backpackers, and campers.

  2. Filtration Technology: The Microfilter utilizes MSR's advanced hollow fiber technology. The filter consists of a series of hollow fibers with microscopic pores that effectively remove bacteria, protozoa, and particulate matter from the water, providing clean and safe drinking water.

  3. Pump Action: The TrailShot Microfilter features a simple pump action mechanism. To use it, you submerge the intake hose into the water source and squeeze the rubber bulb repeatedly. This creates a suction force, drawing water through the filter and expelling clean water through the output hose.

  4. One-Handed Operation: The Microfilter is designed for easy one-handed operation. The squeeze bulb is ergonomic and allows for comfortable pumping even in challenging conditions. This feature is particularly useful when you need to use the filter while on the move.

  5. Quick and Efficient: The TrailShot Microfilter is known for its fast filtration rate. It can filter one liter of water in approximately 60 seconds, which means you can quickly replenish your water supply during outdoor activities without significant delays.

  6. Long-lasting Filter: The Microfilter's hollow fiber membrane has a high filter capacity, capable of treating up to 2,000 liters (or 528 gallons) of water before requiring a replacement. The filter can be cleaned and maintained in the field, extending its lifespan and ensuring long-term use.

  7. Versatile and Field-Maintainable: The Microfilter is compatible with a variety of water containers, including hydration bladders, standard water bottles, and even directly drinking from the water source. It comes with a removable cleanout plunger that helps flush out any debris and maintain optimal filter performance.

  8. Effective Filtration: The MSR TrailShot Microfilter removes 99.9999% of bacteria (such as E. coli and Salmonella) and 99.9% of protozoa (such as Giardia and Cryptosporidium), exceeding the EPA's water treatment standards.

  9. Reliable and Durable: MSR is a reputable outdoor gear manufacturer known for producing high-quality products. The TrailShot Microfilter is built to withstand rugged conditions and is constructed from durable materials to ensure reliability and longevity.

  10. BPA-Free: The Microfilter is made from materials that are free of bisphenol A (BPA), a harmful chemical commonly found in plastic products, ensuring that the filtered water remains safe and free from contaminants.

Overall, the MSR TrailShot Microfilter is an excellent option for outdoor enthusiasts who prioritize portability, convenience, and reliable water filtration. It provides a convenient solution for obtaining safe drinking water from various sources, making it a valuable tool for outdoor adventures and emergency preparedness.

Clean water all day—without the weight. That’s the advantage the TrailShot Microfilter provides. Designed to hide in stash pockets and deploy quickly, this tiny water filter lets you drink directly from sources along the trail for instant hydration, and fill your vessels with clean water. Easy one-handed operation filters one liter in a mere 60 seconds, so you can get back on the trail quickly and moving again. At just 142 g (5 oz.), the TrailShot water filter is the ultimate filter for fast-paced, high-mileage adventurers, like trail runners, hikers, fast-packers and mountain bikers.

  • Tested: Meets U.S. EPA drinking water standards* and NSF protocol P231 for removal of bacteria (99.9999%), protozoa (99.9%), and particulates.
  • Pocket-Sized & Light: Like small water bottles, energy chews, mini bike pumps, and tubes, this 142 g (5 oz.) filter disappears in stash pockets.
  • Instant Hydration: Drink directly from the source—without lying in the dirt—and refill your bottles or hydration reservoir with clean water.
  • Quick-Deploy: Zero set-up and simple one-handed operation fills 1-liter bottles in 60 seconds.
  • Simple to Clean: A few shakes helps restore flow rates in the field; no tools required.
