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 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 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.
The different types of contaminants found in our water can have different effects. Some make water taste terrible, for example, and can even dry out your skin. And there are also chemicals in water that are known to cause cancer. So you really do need a good water filter at home.
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.
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.
But how does an activated carbon filter, or AC filter, work? They use charcoal or another carbon substance to absorb water impurities.
And there are other water filtration systems too. You can get ion exchange filters and reverse osmosis filters and even water distillers. And all of these can be effective at removing different types of contaminants.
So the type of filter for your home is the one that removes the impurities that will be in your 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.
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.
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.
So for great tasting clean healthy home water find a good 2 stage AC filter.
