Buying Guide

I know you are ready to get a survival water filter, but before you make any quick decisions, there are some things you may want to consider first.

If you are curious,  watch the video below for some additional information about how water filters generally work

It’s easy to get lost in a pool of information, but I would like to share with you what you top considerations should be when thinking about which survival filter to buy. Remember, a lot depends on your preferences and specific needs.

Let me offer you some simple considerations that you should make when buying your filter.

Ways to Purify

Thinking about the way filters purify is important because there are some differences. The two main ways to purify water for portable filters are pump filters and gravity filters. I will highlight the differences of each in the sections below.


When we are looking at a pump filter, they are often quicker than other types. They filter at a rate of around 1-2 liters per minute.

When we look at gravity filters, you will be waiting longer, around 1 liter a minute. Yet, with a gravity filter there is less manual work. All you need to do is sit and wait.


Depending on how you will be using the filter, convenience is a consideration you should make.

Pump filters are pretty easy to use, contrary to their name. You won’t be pumping with all your might for hours on end, don’t worry.

Gravity filters are somewhat more convenient because you don’t have to do any work, but you do need somewhere to hang the filter.

There are also countertop filters, which are extremely convenient because you just pour water in the top and you are good to go.


When thinking about your which filter to purchase, you want to check how much water they can filter. This is a consideration that is important because you can judge how long the filter will last before you have to buy a new one. In general, pump filters last longer than gravity.


Let’s be honest, taste is important, especially when it comes to water. Water from pump and gravity filters have a natural taste. You want to check if the filter has carbon, because this can help to eliminate smells that might come from the water.


Think about how much water you will need. The suggestion from the CDC is one gallon per day per person. Remember, that you are not just getting water to drink. You also will be using water to cook and to clean yourself.

Purifying Efficiency

You want the water you are drinking to be clean and safe. That means it is important to check each filter to see exactly what it is getting rid of and at what capacity they eliminate contaminants.

Some filters eliminate viruses, while others are better at removing bacteria and protozoa. What dangers are in your local water? It is important to know this, so that you choose the right filter because they are each designed with specific people in mind.


I know that it seems silly to put a price restriction on the safety and livelihood of you and your family, but it is still a consideration you have to make. There are some very inexpensive options that still offer some of the same things that the higher priced items do.

If price isn’t a concern, you may get a something that is more convenient or has the ability to filter a larger amount of water.


When it comes to having clean drinking water, it is better to be safe than sorry. If you are not prepared for an emergency water outage, you could be risking the life of you and your family. There are many effective and high quality products out there that can be your salvation in the case of some unexpected water shortage. You do not want to be the one who is unprepared in this situation.

I have shared information with you about the top filter brands, products and a buying guide that will help you make the best choice.

Ultimately, it is up to you to decide what the best survival water filter is for your needs. I assure you, the choice you make will be life-changing, literally.
