When Do You Need Survival Water Filters?

A water filter is not just for preppers. Anyone who is planning on spending time outdoors needs a survival water filter.

If you are hiking, camping, hunting, or even in a survival situation because of a natural or man-made disaster, you need access to clean water.

You may find yourself in a situation where the water supply gets cut off, and you need it, whether it be hiking or a natural disaster, or even a zombie apocalypse!


It's recommended for anyone planning on hiking that you carry some type of water filtration system.

The backcountry might be beautiful, but it also makes it one of the most dangerous places to be if you do not have a way to obtain fresh water.

It can also be one of the hardest places to find water if you get lost or injured.


Hunters may find themselves in the same situation as hikers but in even more danger.

Scooping water is not easy, especially when it is cold. Not only is it difficult to get it in a container, but it also is easy to get sick from the bacteria in the water.

This is why it is important to find a way to purify the water before consuming it. Survival water filters should work in any water source, be it from a pond, lake, stream, or from the ground.

Campers and Vanlifers.

Being a camper is fun, but carrying a heavy jug of water from the home can be hard work, and it's not very easy to carry multiple jugs of water.

A water filter can be purchased that does not take up a lot of room. Small enough to be put into a backpack or the trunk of a car. This way, the water filter can easily be taken with you to any location.

Natural Disasters

While we hope that you will never experience this type of situation, natural disasters can occur at any time and often in places you do not expect.

Floods, hurricanes, tornadoes, earthquakes, and tsunamis can be devastating and limit access to safe drinking water. 

The best prepper water filter will be able to give you fresh water while you wait on help to arrive.

Zombie Apocalypse

Okay, it doesn't need to be actual zombies, but if something like this did happen, it could become difficult to find clean drinking water.

You might have to keep yourself alive without any outside help, possibly having to make water safe to drink.

If this happened, you would want to make sure you have a water filter with you.

Biological Outbreak of Disease

When a disease outbreak occurs, many people will be told not to drink the public water, and bottled water may not be available.

In a biological outbreak, you need to ensure that your water is clean and safe, especially if you are depending on it for cooking, cleaning, and drinking.

Foreign and Local Travel

Many countries do not have regulations for clean drinking water. Even in the United States, many rural areas still use wells as their primary water supply, and the water is not always treated properly.

Some of the places where drinking water is unsafe could surprise you. Most people will not know when they plan to travel that the water might not be safe to drink, so be prepared and carry a survival water filter with you.

Weakened Immune System or Older

The elderly and those with weakened immune systems may not be able to handle bacteria, viruses, or other harmful substances in the water they consume.

This can lead to dangerous health problems. A water filtration system will ensure that you are getting clean, safe water every time.

Daily Use

For anyone who lives in a rural area, some of the water may not be safe to drink due to pollution. In order to have clean drinking water, you will need a survival water filter.

Types of Survival Water Filters

There are many different types of survival water filters, and some require more effort than others. Below are some of the most common types and the pros and cons of each type.

Chemical Water Filters

Chemical water filters can be very effective in killing biological and chemical threats, but they can be time-consuming and dangerous. They work by passing the water through a chemical, such as iodine or chlorine. However, if the water has a high concentration of these elements, this can be dangerous.

UV Water Purifier

UV water purifiers can be a great option for removing biological threats, but the effectiveness depends on how much sunlight you have. UV water purifiers work by passing the water through UV light. If there is not enough sunlight or the water is not moving fast enough, it may not be effective.

Filtration System

A filtration system will do a great job at removing sediments. However, it can be difficult to transport and is not effective against biological and chemical threats.

Gravity Fed Water Filter

Gravity-fed water filters are effective at removing a variety of contaminants and biological threats, and they are easy to transport. However, they do take a little longer to filter water.

Reverse Osmosis Water Purifiers

Reverse osmosis water purifiers are very efficient at removing a wide range of contaminants. However, they are hard to transport, can be expensive, and can waste a lot of water.

Water Purification Tablets

Water purification tablets are a great option for short-term use. However, they do not remove biological or chemical contaminants.

Water Purification Straws

Activated Carbon

If you need to remove a lot of biological or chemical threats from your water, activated carbon may be a good option. Keep in mind when choosing this option that it wastes a lot of water and is not effective against radiation or heavy metals.
