Sawyer 3-Way Inline Water Filter
The 3-Way Inline Water Filter is a solid top choice due to its rapid flow rate, incredible ease of use, and ability to produce insanely filtered water. Sawyer is notorious for top-notch filters. This one, if used correctly, offers exceptional protection from bacteria and protozoa since these organisms can't physically pass through the filter pores. Sawyer also makes a purifier that can remove viruses if that is a possible issue on your trip. When the filter is in place, you can simply fill up your bladder and immediately start drinking. If your water source contains large particles or sediments, it's a good idea to pre-filter your water through a cloth, microbag, or even a coffee filter before running it through the filter to avoid damage. The system also comes with a faucet attachment so you can filter tap water while traveling. To top it all off, you get a one million gallon guarantee, which means if you properly clean and care for your filter, it can last a lifetime.
