What is a Survival Water Filter Straw and Should You Consider Buying One?

Survival Water Filter Straw

Updated February 2021 – When it comes to keeping up with the latest technology and making sure your survival kit is complete, you simply can’t ignore the many advantages of the survival water filter straw. This relatively new type of personal and highly portable water filter allows you to filter water as you drink, using it like you would a simple straw.

Some survival straws are designed to filter more than 10000 liters of water during their lifetime, and that volume of filtration can be increased further depending on how dirty the water is.

What is a Survival Water Filter Straw Used for?

Whether you’re on a camping trip or challenging the elements hundreds of miles away from civilization, water filter straws can help provide clean, drinkable water with ease, one of the main reasons why they are an absolute must for stashing away in your bug out bag.

You can use survival straws to filter river and lake water, and they will remove all unwanted bacteria and contaminants. They are extremely portable and very easy to use, and you won’t have a problem with poor taste even when filtering dirty water, although some people have more sensitive taste buds than others.

Construction and Technical Details

Most commonly, these devices are made using plastic tubes that can vary from 4 to 12 inches in length. Water is drawn through the straw by suction, in much the same way you would when using a regular straw. The sucked up water will pass through hollow fibers that are able to filter out any dirt and microscopic particles that might be harmful, or even life-threatening.

The process, as mentioned, is powered by suction, and there are no moving parts. Therefore there is never any need to remove or replace any internal filters. Once a survival straw has reached the end of its usable life it can be simply replaced as they are extremely affordable.
