Water Filters. How Do They Work?

There are lots of people worried about our water. And in particular about whether it’s healthy to drink it. If this worried you then you may be interested to find out some more about water filters and water filtration in general.

How exactly does a water filter work? What does it do? Here’s some of the basics of water filtration, you ought to find out as much as you can before you buy a water filter.

The first thing that you need to think about is why you need a water filter. There’s a huge range of different nasties that you can find in our drinking water and different filters filter different things.

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.

There’s different methods of water filtration that can be used. The first of these is the physical removal of solids, or physical filtration. This is really just a fine filtering or straining of water using a membrane that doesn’t allow particles of a certain size or bigger to pass through.

The second method of water purification is chemical filtration, which works by removing impurities by an active chemical that the water passes through.

One of the most effective filters is an activated carbon filter. These are extremely popular filters and most effective and are found in many houses throughout our country.

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.

There’s in fact a wide range of different types of water filters available. For example reverse osmosis filters, ion filters and even water distillation. And all can remove certain types of impurities.

The type of water filter system that is right for your home will ultimately depend on what type of impurities are affecting your home water.

AC filters are very good and are by far the most popular water filters found in homes in our country. But they do have some drawbacks. For example they do not filter out flouride, sodium and nitrates. But they do filter chlorine, a major contaminant.

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.

It’s not essential to know the exact details of how water filters work as it gets extremely complicated. What is important is that you understand that there is no one water filter that removes all contaminants, but that if you want the best filter you need a 2 stage activated carbon water filter. And it is clear that drinking water filters are a great way to keep drinking water clean and safe from hazardous chemicals.

So for great tasting clean healthy home water find a good 2 stage AC filter.
