The Best Gravity Water Filters of 2023

This 1.59-gallon portable gravity water filter for camping is great for groups and easy to transport, thanks to the included carrying case and a light weight of just 12.3 ounces. It also comes with both a clean and dirty water reservoir, so there’s no need to have an empty container ready to dispense the water.

It filters through 0.46 gallons of water per minute, removing 99.9 percent of bacteria, and lasts up to 1,500 liters before it needs to be changed. The microfilter has also been third-party tested to ensure that it meets EPA and NSF standards for the removal of bacteria and protozoa.

However, it’s important to note that this system does not filter chemicals since it does not contain an activated-carbon filter. Its hollow fiber membrane filter is not designed to remove volatile organic compounds (VOCs). The company does offer a separate carbon filter for use with the Platypus water filter, however. Platypus sells a smaller 1-gallon (4-liter) gravity water filter as well.
