Water Purifier For Home Usage – The Pros and Cons

Little discussion is needed when considering a water purifier for home use. We all have noticed the bad taste of water when it is contains synthetic chemicals like chlorine or fluoride. It is up to us to choose the right water purifier for home use in order to combat the bad.

Distillation heats water to a boiling point where the water then vaporizes. At that point, many contaminants are separated from the vapor.

The vapor is then condensed, that is, it is turned back into water that is much cleaner than before.

A major advantage of distillation is that takes away a wide range of pollutants, for example pathogens and chemicals.

However a big disadvantage with distillation is that many synthetic chemicals boil at a lower temperature than water does and therefore the chemicals are vaporized and condensed along with the water. Therefore the distilled water you drink may not be as clean as you think.

Distillation also uses a lot of energy and has a slightly higher than average waste water ratio compared to some other methods.

An ultra-filtration device acts like a molecular sieve in which suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. The filter takes away dissolved molecules according to their size. It is efficient in taking away microorganisms and synthetic chemicals.

A carbon absorption water filter gets rid of unpleasant tastes, smells, chlorine, gases and many other chemicals. This method can also get rid of microorganisms.

Carbon filtration has been recognized by the U.S. EPA as the best available technology for filtering VOCs and THMs. Unlike distillation, carbon filtration does not get rid of the essential minerals in water, allowing for great tasting and healthy water.
