MSR Trailshot Replacement Filter Cartridge

This extra-large AutoFlow gravity filter system delivers 10 litres of clean water fast—all while you set up camp, prep dinner or relax. And its big capacity means fewer trips to the river to haul the water you need. Similar in packable size to a 4L system, the AutoFlow XL system's durable flat base doubles the water volume for only 340 g (12 oz) of total weight.

These test strips range from 0 to 5 ppm and will help you determine if the water you have treated has a safe chlorine residual. The target concentration range is 0.2 to 2 ppm, 30 minutes after treating the water.

Pump action water filter with combined microporous ceramic and carbon filters. The ceramic filter removes all water-borne disease including bacteria and cysts and the charcoal filter removes chemical impurities including chlorine and iodine.

This compact (just 5oz) water filter device enables you to clean water all day every day! Simply put the tube of the Trailshot in the water supply, pump the bottle to filter it and either drink from the tube or fill up your bottle/ hydration system!
