Quality Water Filters 4 You Posting Page
Monday, June 6, 2011
Carbon filtration, in terms of water filters, is a very effective way to remove contaminants from water. The main component behind carbon filtration is, of course, carbon. The basic element has a very long history of being used to absorb various contaminants. Most people do not know it, but a single pound of carbon has an effective surface absorbent rate of over 100 acres. This is only one reason carbon filtration is so effective. There are more!

In addition to carbon filtration having such a large surface area in which to trap contaminants, activated carbon has a slight electro-positive charge added to it. This charge allows the carbon to be highly attractive to various impurities; think of a magnet attracting iron filings to get a better mental image. As the incoming water flows through the positively charged carbon surface, the negative ions that are common for contaminants are attracted to the carbon granules.

Carbon filtration water filters fall into two broad groups. The first uses granular activated carbon (GAC). The second group of water filters uses carbon blocks. Carbon block water filters have a higher contaminant removal ratio when compared to granular type water filters.

A typical counter-top or under-the-counter carbon filtration water filter uses 12 to 24 ounces of activated carbon. The type of carbon used varies, with the most common carbon types used in water filtration being bituminous, wood, and coconut shell carbons.

Coconut shell carbon costs more but is considered the most effective of the three.

Carbon filtration water systems are very popular in a number of home water treatment systems. These types of water filters can be found as either standalone filters which can reduce or eliminate bad tastes and odors. They can also eliminate or reduce chlorine, and many organic contaminants in municipal water supplies, resulting in improved drinking water. Carbon filtration systems can also be found as pre-treatment systems within reverse osmosis systems in which they reduce the level of several types of organic contaminants, chlorine, and other contaminants that can plug up the reverse osmosis membrane.

While carbon filtration units are very good at what they do, they do have some limitations. For instance, carbon filtration water filters do not work well in removing all dissolved inorganic substances. They are also not effective in removing minerals and certain types of salts that cause hard water. If your incoming water has issues with dissolved inorganic contaminants or hardness issues, consider using a reverse osmosis water filter or you may want to look into using KDF-55 or manganese greensand water filtering system.

Carbon filtration water filtering systems range in price, depending on the type of system being purchased. Whole-house systems will, of course, cost more than smaller stand-alone or point of use water filters.

Consumers who are interested in improving their drinking water and want to learn more about using carbon filtration systems should contact a reliable water filter vendor for more information. It is often important to discuss your individual needs before choosing a particular water filtering system.
