Before you buy a water filter or water purifier, you should understand the difference between the two as well as their individual pros and cons.

Water Filters

A water filter is a porous substance, like activated carbon, which removes unwanted sediments and substances such as harmful toxins and chemicals from water.

Although they are stellar, they are, when used by themselves, inadequate for turning well or municipal water, as well as water from natural sources like streams, rivers, ponds, etc. into safe drinking water.

A water filter helps in improving the taste and odor of water and reduces the level of chemical contaminants present in water.

Water Purifier

A water purifier is a system designed to remove 90 to 95% of all contaminants, such as chemicals, viruses, biological contaminants, and other materials in water.

You will find three recognized water purifier technologies nowadays – deionization, reverse osmosis (what the US Navy uses on their ships) and distillation (what is used by the UAE and should be used by cities like LA since Lake Mead is being sucked dry).

As they have powerful capabilities, purifiers must be used to form the foundation of any drinking water system so that you can create truly safe and pure drinking water.

It is not easy to make sense of all the different water filters and water purifiers that are available in today’s market, and unfortunately, people often use these two terms interchangeably, adding to the confusion.

If you are looking for something that is easy to use and can be carried and stored easily when you are on one of your wilderness trips, your best option is a water filter. It is the most hassle-free way to make sure that you have safe drinking water out in the great wide open.


When you have a fantastic filter with you when you are out on your outdoor trips, you never have to worry about always having clean and safe drinking water.

Surviving in the wild is tough and the last thing you want is to get sick because you drank contaminated water from a natural source somewhere.

To make sure that you choose the best water filter to carry on your outdoor adventures, there are a few factors that you should keep in mind, such as:

Filter Capacity

One of the first things to check in a survival filter is its capacity. This depends on how much drinking water you will need while you are out in the wilderness. The filter should be able to produce the amount of clean water you need every day.

Additionally, picking a survival water filter with a larger capacity allows you to filter water for other people if you are traveling in a group – they will probably have their own, but you can make the process of filtering water faster by carrying a high-capacity survival water.

Ease of Use

With the technology available nowadays, there are various types of survival filters that you can choose from – some of them are highly innovative and advanced.

The problem is that these advanced filters can be difficult to use. When you are in the wilderness, you need a survival water filter that is easy and convenient to use.

You should be able to quickly get clean, safe drinking water whenever you need it. Buying a survival water filter that requires complicated steps to eliminate contaminants will slow you down and maybe even prevent you from effectively getting safe drinking water.


Another critical factor to consider when choosing a survival water filter is the size. While you want to make sure that you have enough drinking water, you also need to make sure that your filter is not too bulky and a hassle to carry into the wilderness.

A compact survival filter is easy to carry around and does not slow you down as you make your way through the different terrains and conditions you go through when you are out in the wild.

It is also easy to store away when it is not in use as it does not take too much space in your backpack.


Like size, the weight of a survival water filter is a critical consideration when you are choosing one to take with you on your outdoor trips whether you are camping, hiking, or hunting.

As mentioned earlier, you do not want to be slowed down while you walk through the wilderness.

A lightweight filter makes sure that you avoid this problem. It is easier to carry in your backpack – you can make your way through the great outdoors without tiring too easily and feeling bogged down by your water filter.


Last but not least, you need to check out how effective a survival water filter is in eliminating the various contaminants in water.

Three main classes of organisms are typically responsible for contaminating water that you find in the wilderness – bacteria, viruses, and protozoan cysts.

Survival water filters can take care of bacteria and protozoa – you will either need to treat your water chemically, boil it, or get a filter with purification technology to eliminate viruses. Avoid buying filters that claim to remove viruses.

You should choose a 0.1 Micron absolute hollow fiber membrane inline filter that can eliminate 99.9% of bacteria and protozoa.

One of the essential things to survive in the great wide open is water – clean water that is free of any contaminants and safe to drink and cook with.

When you are checking out survival water filters to carry on your next adventure, keep the tips mentioned above in mind and you will be sure to find a high-quality, effective filter that meets all your needs.


Surviving in the wilderness can be difficult if you do not have clean water to drink. How many bottles of water can you carry with you, right?

To make use of the water you get from natural sources, you need a fabulous and dependable water filter to help you get rid of bacteria, protozoa, and other contaminants.

Nowadays, you can find a wide range of survival water filters to carry with you on your outdoor trips and help you get safe drinking water.

Check out the products mentioned above to get a better idea of what is available for you to choose from. It will help you find the best survival water filter to suit your needs and budget and survive during your time in the great wide open.
