Widely regarded as the easiest-to-use water filter, the SweetWater® Guardian™ Microfilter has a unique lever-action pump handle that provides maximum pumping efficiency with minimal effort. It pumps water on both up and down strokes, resulting in a fast flow rate of 1.25 liters per minute. When not in use, the handle folds flat for compact storage. Weighing just 11 ounces, the Guardian™ Microfilter is one of the lightest on the market. It uses replaceable filter cartridges, and each cartridge filters up to 200 gallons of water. A layer of granular activated carbon surrounds the filter element and improves the taste of unsavory water. The Guardian™ Microfilter eliminates over 99.9999% of all waterborne bacteria and 99.9% of common protozoan parasites such as Giardia and Cryptosporidium. It comes with a stainless steel prefilter, two color-coded silicone hoses, foam float, water bottle adapter, cleaning brush, and carry bag
