Home Drinking Water Filters - How to Choose?

A home water filter fulfills the task of separating the unwanted harmful particles from the contaminated water, by various ways. Unfiltered water is can potentially be saddled with bacteria which are the prime causes for diarrhea, cancer, skin irritation, etc.

Chlorine is often found in water supply as chlorine can combat various harmful microbes that are found in the water pipes. Albeit chlorine can do wonders by killing those deadly microbes but when it reaches our body, it can do considerable amount of damage, by giving birth to dry skin, bad hair and other type of diseases. This is where home water filters comes to our rescue by removing the unwanted chlorine from the water.

So how do water filters work? The answer largely depends on the type of purification method used for home water filters. Purification methods primarily consist of reverse osmosis, granular carbon, ion exchange, sub micron filtration and multi media block as a procedure to eliminate all type of contaminants.

A home water filter which utilizes the method of reverse osmosis functions by forcing the water through a layer which is semi porous in nature. Particles which are smaller in size than the semi porous layer will pass out of the same. And larger contaminated particles will get blocked in the layer and prevent it from being by us. The method of granular carbon is based on the theory of absorption. Harmful chemicals like chlorine get attached to the granular carbon and it is one of the most effective ways to combat chlorine through the use of home filters.

Home water filter that uses ion exchange as its purification method relies heavily on the theory of magnetism. Particles like lead are found in the supply water which has the capacity to induce various health problems. So it is imperative to get rid of them. Since metallic substances carry a nominal amount of electrical charge, it can get blocked in an area that contains the opposite electrical charge. And ion exchange works on this theory. Harmful particles such as lead are eradicated by our home water filters.

If you are looking for a cheaper option then home water filter which uses sub micron filtration as its purifying method will perfectly suit your needs. Its function is similar to the reverse osmosis process albeit the cost is much lower. Multi media block attracts chemicals such as trihalomethane and volatile organic compounds, which are one of the causes for cancer. Multi media block used in home filters are made of carbon and other elements so that they can easily attract all the harmful chemicals. For home filters to work effectively it should use all the above mentioned steps so that every type of contaminants can be eliminated from the water.
