The trail is getting steeper and the sun is beating down on your skin, draining your energy with each aching step you take. Your head starts to feel cloudy and light, so you take a knee and try to regain your equilibrium. Unfortunately, your throat is dry and you’ve never felt more thirsty in your entire life. Luckily, you have your purifying water bottle to turn cool stream water into a refreshing drinkable liquid.

Roaming through nature’s landscapes is therapeutic, but in order to enjoy the full experience of being unplugged, you have to be prepared for the worst. Getting a standard water bottle isn’t enough, especially for longer trips in the backcountry. With a filtration water bottle, you can scoop up a tall drink anywhere there’s still or moving water and hydrate without fear of getting sick. It’s a simple piece of gear, but it’s a must-have if you spend most of your free time outdoors because it can save your life. We’ve analyzed a heaping number of decontamination containers and filtered out the mediocre offerings to build this list of the best purifying water bottles available.


Clean Water Anywhere

The obvious reason to get a purifying water bottle is to have the convenience of turning dirty water into healthy, drinkable water for your adventure. In addition, it’s also beneficial for the environment. With a purifying water bottle in your hiking backpack, you won’t need to purchase cases of plastic water bottles, helping to preserve our environment. And you’ll also benefit financially so you can invest your money in more EDC treats for your loadout. If you’re a pure adventurer who practically lives outdoors, or a weekend warrior addicted to getting your fix of backcountry exploration, a filtration water bottle is a must-have item.

How It Works

Before we get to the list, we’ll briefly go over how purifying water bottles work. The water decontaminating bottle has its own built-in filter system. A typical purifying bottle will utilize a filter made with activated charcoal with an electro-positive charge. When the water passes through the filter system, it removes bacteria, chlorine, metals, and also any weird tastes for your convenience. The design of water bottle filters varies, as some will remove the contaminants from the water as you’re drinking it and others will filter the liquid as it enters the container.

There are also water bottle filtration systems that remove undesirable substances and sediment, but do not work well for backcountry use. Although these types of water bottles will remove certain contaminants, they are not built to remove bacteria and viruses, so they shouldn’t be used for filtering open source water. We have included some filtration water bottles made just for tap water to provide you with further options for your convenience. Think about which type aligns with your preferences before committing to a particular model.
