Quick Answer
For ultra-light backpacking, the best pocket filters are those that are compact, lightweight, and effective at removing bacteria, viruses, and sediment from water. Popular options include the Sawyer Mini and the MSR TrailShot. These filters weigh in at under 2 ounces and can be easily carried in a pocket.
Choosing the Right Filter
When selecting a pocket filter for ultra-light backpacking, consider the filter’s flow rate, weight, and effectiveness against a wide range of contaminants. The Sawyer Mini, for example, has a flow rate of 0.1 liters per second and weighs in at just 2 ounces. It is also effective against bacteria, viruses, and sediment down to 0.1 microns.
Filter Maintenance and Use
Proper maintenance and use of a pocket filter are crucial to ensuring its effectiveness and longevity. This includes regularly cleaning the filter with soap and water, storing it in a dry environment, and using a dirty water treatment such as the Sawyer Pre Filter to extend the life of the filter. To use the filter, simply submerge it in the water source, attach a hydration hose or straw, and drink directly from the hose.
Additional Features and Considerations
Some pocket filters, such as the MSR TrailShot, come with additional features such as a built-in strainer and a flip-top design for easy cleaning. When choosing a pocket filter, also consider the type of terrain you’ll be traveling in and the potential contaminants you may encounter. For example, if you’ll be traveling in areas with high levels of sediment or particulate matter, a filter with a higher micron rating may be necessary.
