If you’ve read about the problems with drinking contaminated water you might be getting interested in water filtration. You will have heard of charcoal water filters or carbon water filters or even activated carbon water filters. What are these water filters?

Charcoal is a substance created by heating organic matter to high temperature in the absence of oxygen and a charcoal water filter is one that uses charcoal for the filtration process. The organic material commonly used is coconut husks.

Charcoal has various properties, primarily that it is extremely porous and this is what is necessary for successful water filtration. These pores allow water, and contaminants, to pass through and for the contaminants to be absorbed by the carbon by means of chemical attraction, because many carbon based or organic compounds are chemically attracted to carbon.

That is what charcoal, or carbon, water filters are. So what are activated carbon, or what is known as AC, filters? These filters use a form of carbon that is way more porous than normal carbon, and this is created during the manufacturing process.

It’s so porous in fact that it can have up to 20000 square yards of surface area per ounce of activated carbon. That’s really porous.

You need to replace the filters occasionally in an AC water filter because the filter gradually clogs up with contaminants as they are absorbed by the carbon.

An activated carbon water filter works well filtering a wide range of contaminants, but doesn’t filter all of them, and for this reason the best water filters use a multi stage water filtration process. Not only is the carbon block, or activated carbon filter used but there is a second stage to the process that removes the contaminants that are not removed by activated carbon filtration.

And in the very best water purifiers available there is no reliance on AC filtering only, because very good it is not sufficient on it’s own. There is a second stage to the filtering process and this stage is used to filter contaminants that the first stage leaves behind, like nasty lead. And the removal of lead is achieved by an ion exchange process replacing lead ions with harmless potassium ions.

And the second stage of the best water filters removes tiny organisms that remain in the water after stage 1 like giardia and cryptosporidium through the use of an extremely fine filtration process. These are the most dangerous water contaminants.

There you have the basics of water filtration by use of carbon, or what is known as charcoal water filters, or activated carbon water filters. The activated carbon is not 100% successful in removing all contaminants, but when used in a 2 stage process designed to remove the contaminants that are left behind by the AC filter, it works exceedingly well. You should expect around 99% of lead to be removed, for example.

I spend time discussing the worlds best water filters on my website.

Many people are interested in a water filter for their home to ensure safe drinking water. Since our drinking water tends to contain a lot of impurities, such as chlorine and pharmaceutical drugs, water filters can be a great option. They can work to remove all of the impurities and provide you with drinking water that is both clean and safe.

And there’s more. A good portable water filter will work by purifying the water without the use of chemicals. Some water purification systems use chemicals to purify the water, but for many people that defeats the purpose. There are many portable filter options that clean your water without use of chemicals.

A portable water purifier is also a great choice for those who like to travel a lot.
