How In The World Do Water Filters Work?

By Peter Abertoning

In our times there are so many people so concerned about their health. And some of these people are concerned about the health effects of drinking our water. If this describes you then you need to learn more about modern water filtration systems.

How does a water filter work and what does it do? Here's some of the basics about the water filtration process. Things that you should be aware of before you buy a water filter.

There's a wide range of different chemicals and toxins that can be found in our water and different types of filter will filter out different types of contaminant.

There are many many different contaminants. Some can make your water taste bad, like chlorine, and can even cause your skin to dry out from showering. And there are many nasty chemicals found in water in small quantities that are known to cause cancer.

Its important to know that there are two different methods of water filtration. Physical filtration is the first method. It works by straining the water, using a tiny piece of textile membrane or gauze.

And then there is chemical filtration that removes various contaminants by chemical methods.

Activated carbon filters are known to be one of the most effective types of water filtration. They are also known to be one of the most popular types of water filters to have in the house.

AC or activated carbon filters are effective but how do they work? They work by the use of some form of carbon, normally charcoal, absorbing the impurities in the water.

Some of the other different types of water filtration systems out there include reverse osmosis, ion exchange, and distillation. All of these water filter systems are known to be useful for removing certain impurities.

The type of impurities that are found in the water that you have in your home dictate the type of water filter that you need.

AC water filters can remove a wide range of impurities found in water like chlorine and pesticides but there are also some contaminants that they cannot absorb. For example an AC filter will not remove flouride, sodium and nitrates. But they deal with the vast range of different impurities that are found in our drinking water and for this reason they are by far the most popular of water filters.

So for this reason it is now possible to get 2 stage water filters. One stage is an activated carbon water filter and there is a second stage of water filtration that also removed those impurities that are not removed by the AC stage of filtration. These are now by far the best water filters that can be found with modern technology.

There's quite some science behind how water filters work and any more than this will blind you with science unnecessarily. Suffice to say that no water filter removes every single contaminant, but that if you want the best water filter then consider a 2 stage activated carbon water filter. They are the best water filters that modern technology can produce. There is no doubt though that there are nasty chemicals and toxins in our water that you ought to remove before you drink it.

For water that has a good taste, a 2 stage AC home water filtration system is the right choice for you.
