Water Filters. How Do They 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 do water filters work? Here are some of the things that you should know about the water purification process if you have thought about getting a filter for your home.

The first thing that you will want to take into consideration is why a water filtration system may be necessary. Keep in mind that there are many different toxins and chemicals that can affect our drinking water.

They can make drinking water taste awful and can even cause the skin to dry out. Even worse, many of these chemicals in drinking water are known to cause cancer. Due to all of these reasons, water filtration is a pretty much a must for any home.

One method of filtration is to phyically filter out solid contaminants bigger than a certain size through a filter or membrane that allows water to pass through but removes anything bigger than the size of the filter holes.

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.

How do water filters work when they are carbon activated? These filters are based on charcoal, which absorbs the impurities of 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 impurities that are found in the water that you have in your home dictate the type of water filter that you need.

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.

It is now possible to buy 2 stage water filters to overcome this problem with AC filters. Whilst an AC filter is very good on it's own a 2 stage filter will have a second stage of filtration that removes those contaminants that do not get removed by the carbon. These are now by far the best water filters that you can get.

The science behind water filters can be confusing. But the bottom line is that no water filter will remove every single contaminant. The one that comes closest if the activated carbon 2 stage water filter and it's this that you want if you need the best water filter. And you do need the best water filter as there is no doubt that our water is seriously contaminated.

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