How Do Water Filters Work Anyway?

‘How do water filters work?’ is a common question asked by many people.

In many cases, what they are really asking is, `How do I know this water filter is GOING TO WORK?’

There are many different types of water filters and systems available, some being more effective than others in the production of high quality drinking water.

Why do I need a water filter?

You may as well be asking `Why do I need to go to bed?’ The answer may be obvious to some, for others, read on to find out what your regular tap water contains:

• Chlorine
• Lead
• Agriculture and Industry contaminants
• Natural sediments
• Bacteria
• Pharmaceuticals

So when asking the question, `How do water filters work?’ You should expect a company specialising in water filter technology, to reassure you by letting you know they work through removing all of the above.

So how do water filters work? For the beginner

As mentioned previously, there are different types of filters that are capable of producing water of varying quality. Lets have a closer look at some of the processes involved in the creation of purified water.

Reverse Osmosis – This process involves pushing high-pressured water through a semi-permeable membrane. The idea is that purified water molecules will be on one side of the membrane and all the `bad’ molecules will remain on the other side, away from the purified water.

Perfect theory, if all the bad molecules were the same size, or if all the bad molecules were bigger than the water molecules. Unfortunately, methods like this do have some drawbacks in the quest for purified water.

Carbon Filtration – Carbon filtration is a popular form of water purification technology and a few manufacturers have come up with the idea of using this successful method in combination with others to create, what they believe to be, the purest filtered water available.

Carbon filtration has the potential to:

• Remove the smell of unfiltered water
• Enhance the taste
• Remove Chlorine
• Filter out Volatile Organic Compounds (VOC’s)
• Remove a variety of toxins and chemicals

One of the reasons that carbon filtration is combined with other methods to create a really unique and successful filtration system, is so that it also has the ability to remove heavier metals.

Ultraviolet Radiation – A good form of water purification technology for removing viruses and bacteria and is also capable of sanitising.

The process of ultraviolet radiation involves passing water through a chamber containing the ultraviolet light, which has the strength to kill the bacteria. Again, the drawback here is that it is unable to remove all of the offensive contaminants in our drinking water on its own.

Are you still asking the question, `How do water filters work?’

The processes of Reverse Osmosis, Carbon Filtration and Ultraviolet Radiation are of course, not the only methods of water filtration. Other methods also include:

• Ion exchange
• Micro Filtration
• Ultra Micro Filtration
• Distillation

How do water filters work? The find the best answer to the REAL question, conduct some online research yourself, compare systems and results and then you will know if the water filter is GOING TO WORK for you.
