The 13 Best Survival Water Filters on the Market

Water is essential to human life, and whether you are trudging through the Amazon rainforest or surviving a post-apocalyptic disaster; humans need water! Survival water filters are essential for long journeys or for stays in areas that may or may not have perfectly clean water. Some people (myself included) even like to filter water at home or in their own hometowns.

A lot of people attach water filters to their taps at home or have water filtration systems in their fridges. A person can only go 3 days maximum without water! Clean water is often taken for granted in more developed countries, but in less developed countries; the quality of water cannot be guaranteed, so a solution for clean drinking water is a must. Enter the survival water filter.

Engineering developments in the 21st century have enabled survival water filtration devices to become simplified and portable, and a lot easier to carry around than they used to be! These new portable water filtration devices are the perfect addition to any go bag, camping trip, long hike in the hot sun, or just simply the clean freak who is concerned with having the best water quality possible.

These survival water filters below are built to sift out waterborne bacteria and remove parasites or infectious bodies from the water. There is a very large range of options when it comes to water filters, and in no certain order, here are 13 of the best survival water filter options available on the market.

What are the best survival water filters?

1: MSR Guardian Purifier Pump

The MSR Guardian is a solid survival water filter

This ‘purifier pump’ is actually used by branches of the American military and when it comes to backwater, this pump really pulls out the big guns. The MSR Guardian is known for effectively tackling bacteria, parasites, viruses, and dirt. Its concrete and solid frame allow it to withstand both incredibly high and low temperatures while still performing its duty at an astounding 2.5 litres per minute.

The MSR Guardian is also self-cleaning upon each use. It weighs 2.19 pounds and can filter up to 10,000 litres.

Also, at the start of the year, MSR released the MSR Guardian Gravity Purifier which is a cheaper – gravity fed option.

2: Katadyn Pocket

The Katadyn Pocket is a survival water filtration beast and handles 13,000 gallons at the rate of a litre per minute. However, although it is an impressive filtration device, it is actually quite small.

It is the perfect travel companion, as it only weighs 7.4 ounces, but it does not skimp on its filtration abilities.

The Katadyn Pocket boasts that no microorganism larger than 0.2 microns is able to get through this filter, even though it is small! This filtration device is used by the U.S. military and international wanderers alike.

Katadyn Pocket Water Filter for Backpacking, Group Camping & Emergency Preparedness

The LifeStraw Personal water filter is used all over the globe by non-governmental organisations. This filtration device is extremely light and portable; it only weighs 2 ounces!

Known for its impressive flow of 1.7 litres every minute, this filtration system is ‘survival mode’ designed; meaning that you can drink directly from the source you are filtering from if you need to (without waiting a long time for filtration to occur).

One survival scenario downside to the Lifestraw is that it is designed for a single person to drink at a source of water. This isn’t going to allow you to quickly or easily filter a lot of water. They do have a growing product line though and offer other water filter options.

The device is small enough to fit in a hand, and weighs a mere 2 ounces, similar to the aforementioned ‘Lifestraw Personal’. Really a great size for your bug out bag.

The only downside is that it does not filter chemicals or viruses, unfortunately, which gives it a few holes as a survival water filter. However, it is almost 100% effective when it comes to parasites and bacteria.

It is an ideal option for outdoor wanderers and ultralight backpackers, though it, unfortunately, is not self-cleaning and requires a wipe and manual clean after use. You can attach it to a separate compartment or drink it straight from the water source.
