How to use a Water Filter

Written by The Ready Store

Water filters are very useful in just about every survival or disaster situation.  Drinking the water directly from a water source could put you in danger of getting sick or even worse.  There are many contaminants that can flow freely in water so it’s important to filter them out.

When you use a portable water filter, Water passes through, but bacteria and protozoa do not.

A portable water filter will have two tubes.  You will use one tube to stick into the water source, and the other tube will go into your container.  Next, you will pump the water through the filter and into the container.

They are lightweight and easy to put into your pack.  Some portable filters will actually screw onto the top of your water bottle.  Pumping the water can take some time.  The average filter will produce 3 liters of water in 10 to 15 minutes.

Having said that, clean water is essential to survival, so taking the time is so worth it.  If you are hiking and you find a good water source, don’t pass it by without filling up your water containers.  Otherwise you risk being far from water when you need it most.

Here is a short video where Jeff demonstrates a water filter in action:


When you buy a filter, make sure you test it out before you get into a survival situation so that you are familiar with it and how it works.

Most of all, enjoy the clean water!

    Hand pumps are fine for an individual on a short-term basis. But what about high-volume water filtration? And over a longer period of time?

    Even with stored water eventually supplies will run out. I can’t see hand pumping all day to file a barrel (if that much) not to mention you’ll run through filters quickly.

    Let me disagree with you. I am strictly convinced that proper water filtration is the thing one needs to pay a way more attention these days. Our bodies are almost 80% water. We can’t simply neglect this fact. This water should be purest. Sounds logical? ;)

    Would any compact or hand held water filters suit ocean water if fresh streams or ponds are non existent? The information never says anything about desalination.

    Hey Matthew,
    I’d have to check into it but I’m pretty sure that none of the water filters that we provide desalinate. Sorry about that.

    It would have been interesting to see a container of water taken from the same river and had a lab analyze and compare the filtered and unfiltered samples. Lots of river water can taste good while still having lots of unwanted bacterium.

    Matthew asked about desalination, and I noticed in the video that the product was demonstrated on a river… presumably a salty river. Where I live – near the Chesapeake Bay – our rivers are considered salty. Wouldn’t a river be too salty to use as a drinking source?
