Water Sources and Decontamination

The type of water supply the water is collected from determines how rigorous the water treatment should be.

If you can locate water via a cool spring, melted snow or a glacier, for instance, the water would be fairly pure to start. It is not likely to have gotten polluted by animals or people.

For these sort of water sources, a fundamental water filter is suitable. It is worth remembering that if you realize you will be trekking into an icy or snowy environment.

Though, except if you now live somewhere there’s a lot of snow already, it is more probably you will travelling in the wild or some kind of urban environment when the emergency happens. So you are more likely to be gathering polluted water. You must more intensely filter any water you get from a swamp or a stream.

It will not merely have to be run through the filter, you should additionally purify it as an necessary safeguard. Purification gets rid of not only odors or a bad taste, it removes viruses which might otherwise get through a basic filter.

Single or Group Survival Methods

You should think about the number of folks who will be in the group if you get trapped with no water. If you are sure it will be just you, then you only need a filter straw or a lightweight inline filter.

Otherwise, if it is going to be a big group, filters created for one person usage are worthless. A little pump water filter is a much better choice.  Little pump water filters are capable of filling up several bottles of water quickly, and the chore of pumping could be divided up amongst the group members.

Whilst it is not possible all the time to tell if you will be in the wild a long time, a gravity fed filter is a good choice to bring if you think this is going to happen.

This filter is a lot faster when straining big amounts of water, so it is capable of providing several gallons of water daily if you keep pouring water in it. That makes it a better choice for a camping trip because they take a good amount of area to set them up and they are not that easy to carry around.

A Transportable Water Filter

When in emergency situations, you want your gear to be as lightweight as it can be. If an emergency occurs, you will not have any idea the length of time you will be in the wild, and if your bug out pack is heavy it will be a worse situation.

So this is the reason the top emergency water filter should not weight a lot and should be easy to carry with you. If it’s bulky or awkward it will occupy too much space. You need to get a heavy filter for it to be a good one. A lot of the smaller in-line type of filters will fit in your pocket and are extremely lightweight.

The bigger type of filters like a gravity fed one, isn’t meant to go in a bug out pack. However, a few of the smaller pump kind of water filters will do a good job for a lengthy timeframe and yet fit well into your bug out pack.

It’s a good idea to think about if you’re okay with giving up on taking a big, maybe more effective pump filter so you can bring a lighter one which might require a longer timeframe to filter the water entirely.


You will have to think on if a filter that fits your budget will work as well as one that costs more.  Many of the pricy water filters actually work more efficiently as a long range investment since they filter a larger amount of water than the cheaper ones. So be certain you are comparing the water filters’ specs prior to buying one.

A straightforward, rudimentary filter many times works just as good as the more costly one which has tons of features. It might be better to spend your money on buying other types of survival tools, when the cost equals the quality. It’s a good idea to think about which features are the most important to you in a water filter, plus if you think paying more means it works better.

Another facet of the cost to think about is if the filter you pick has parts that are easy to replace. It is possible the filter could require new parts eventually, so if you get a filter that costs a lot at the start it might eventually cost more money to own than one of the other, cheaper filters.

Simple to Operate

The top emergency water filter needs to be simple to operate without you needing to pour over a manual. If you’re trapped in an emergency situation, you want your ability to get clean water to be free of stress. In an emergency time is vital and you want a process that’s not going to stress you out more.

A few models of water filters need more components to work right, i.e. a special kind of hose. Plus you might need to set them up in a specific manner or they only work in specific environments.

Trendy filters that look like straws can be bought these days. They do seem to have a lot of benefits, but they won’t be much good unless you are willing to be right next to the water source and stick your head down to drink the water via the filter straw.

So it’s vital to think about the ease of using the water filter you choose since the top one can be adapted to your situation as well as your environment.
