How Do You Filter Water for Backpacking?

By Alice Nichols

Backpacking trips can take you to some of the most pristine locations on earth, but what do you do for clean drinking water? To keep your body properly hydrated and your health in check, it’s important to know how to filter water for backpacking.

What Are Water Filters? A water filter is a device that removes impurities from contaminated drinking water. Water filters come in many shapes and sizes, but all of them use a physical barrier or chemical process to remove unwanted particles from the water. Some filters are designed specifically for backpacking, while others are more general-purpose and can be used in other situations as well.

Types of Filters There are two types of filters typically used when backpacking: mechanical and chemical. Mechanical filters use a physical barrier such as paper or cloth to strain out particulates like sand, silt, and other larger impurities. Chemical filters, on the other hand, use a chemical process such as iodine or chlorine to kill bacteria and other microorganisms that can cause illness.

Choosing the Right Filter Choosing the right filter for your needs depends on several factors including where you’ll be backpacking, how often you plan on using it, and what type of contaminants may be present in the water you’ll be filtering. For example, if you’re only filtering clean rainwater then a mechanical filter may be sufficient; however if there are potential bacteria or virus present then a chemical filter will likely be needed. Additionally, if you plan on using your filter frequently then it’s important to choose one that is easy to maintain and replace parts as needed.

Using Your Filter Using a filter is fairly straightforward: simply pour unfiltered water into the top of the filter and let gravity pull it through the filter material until it exits at the bottom as clean drinking water. Make sure to follow all instructions provided with your specific model to ensure proper operation and maintenance of your filter system. Additionally, keep an eye out for any signs of wear or damage which could reduce effectiveness or put your health at risk.


: Knowing how to properly filter water while backpacking is essential for keeping yourself healthy while enjoying nature’s wonders. There are several types of filters available depending on what type of contaminants may be present in your source water; choose one that meets your needs based on usage frequency and type of contamination present. Additionally make sure to follow all instructions provided with your specific model for proper operation and maintenance so you can stay safe wherever your adventures take you!
