Best Filtered Water Bottles for Hiking

When you go hiking do you know what the most valuable thing in your pack is?

It isn’t the food, or the sunscreen or your phone. It is water, plain and simple. Water is the most important thing in your pack.

You see, the rule of three for survival is that you can’t survive three hours without shelter. You can’t last three days without water and you can’t live without three weeks without food.

When you are packing your gear up and ready to head out on your big adventure you may have the rule of three in the back of your mind. You may even load down your pack with extra water bottles just to be on the safe side.

But the problem with loading up so much plastic water bottles is the room they take away from other necessities and the fact you have to lug the empty ones back out with you.

What if there was a way for you to get the water you so desperately need from a source like a stream or a river? But everyone knows that those sources can be uncertain.

There are pathogens and other contaminants that could really mess up your body if they aren’t removed from the water before drinking it.

Sure, you can get iodine capsules to filter your water, or you can get yourself a filtered water bottle. A filtered water bottle gives you the best of both worlds. You have the filtration system in place to clean out all the impurities and you have a way to transport the water with you wherever you may go.

Top 10 Best Filtered Water Bottles for Hiking in 2018

Things to Consider When Buying a Filtered Water Bottle:

But how do you pick the right filtered water bottle? There are so many on the market today that it can be a bit daunting to find the right one. There are a few things to look for and consider before you buy your filtered water bottle.

Look to the Source:

Well, first you need to know what kind of water source you want to filter. If you are an avid hiker and camper looking to filter water from a stream, river, or lake and know that water is dirty, you will need a more powerful filter. You should look for a water bottle that guarantees 99.999% of the contaminants will be removed from the water.

Stages of Filtration:

Many filters utilize carbon to clean the water of impurities. Some even have different stages of cleaning the water to make sure nothing is left but clear crisp water. When you are out in the middle of nowhere you don’t want to be taking any chances with your water. You want a filtered water bottle that will clean out everything.


You don’t want a small water bottle that won’t go the distance especially if you are out hiking miles at a time. You need to know where you are going and know that you need at least 8 ounces of water per hour. This is especially true in extreme temperatures like deserts.

If you are out hiking in extreme weather, you need to be able to bring with you a lot of water. Always double check the size of the water bottle before making a purchase. Plus you should always bring more than what you think you will need.
