Quick Answer
For backpacking trips, the best water filtration systems are portable, lightweight, and effective against a wide range of contaminants. The Sawyer Mini and the LifeStraw Flex are highly recommended options. They are both compact and can filter out bacteria, viruses, and parasites.
Portable Filtration Options
When it comes to backpacking, portability is key. The Sawyer Mini is a popular choice, weighing in at just 2 ounces and measuring 5 inches long. It can filter up to 1 million gallons of water and remove 99.97% of bacteria, viruses, and parasites. The LifeStraw Flex is another option, weighing 2.2 ounces and measuring 10 inches long. It has a built-in filter that can remove contaminants down to 0.2 microns.
Ultraviolet (UV) Light Filtration
For added peace of mind, consider incorporating UV light filtration into your system. The SteriPen is a popular choice, using UV light to kill bacteria, viruses, and parasites in just 48 seconds. It’s lightweight and compact, making it easy to carry on backpacking trips. When used in conjunction with a portable filter, the SteriPen can provide an added layer of protection against waterborne pathogens.
Field Testing and Maintenance
When testing your water filtration system in the field, be sure to follow proper protocol. This includes filtering a small sample of water before drinking it, and regularly cleaning and maintaining your filter or UV light. For example, the Sawyer Mini should be cleaned and rinsed every 100 gallons or so, while the LifeStraw Flex should be replaced every 4,000 gallons.
