The Truth About Water Filter Systems Revealed

water filter system

What is a water filter system? It is a device used to purify water. A water filter cleans water by removing impurities either by a physical barrier impeding water flow or by a chemical reaction, such as reverse osmosis, in which water is forced through a semi-permeable membrane. In the case of reverse osmosis, water is forced through a thin film of material, and in the case of ultraviolet light purification, water is exposed to ultraviolet light for a short time, causing it to become sterile.

A water filter system can be designed to remove a broad range of contaminants, including lead, chlorine, iron, bacteria, viruses, parasites, synthetic chemicals, tars, and other foreign contaminants that may be present in your tap water. A number of domestic contaminants that may be present in your water supply include volatile organic compounds (VOCs) such as benzene, ethylene oxide, and toluene, cysts, E coli, Cryptosporidium, Giardia, and lead, hardness, and magnesium. There are some domestic contaminants that are resistant to some form of disinfection, including cadmium, copper, mercury, lead, and vinyl chloride. The presence of one or more of these contaminants in your water supply may indicate the need for a water filter system.

Reverse osmosis systems use water pressure to force water through a thin film of semi-permeable membrane. During this process, impurities are trapped and removed. This method was developed in the 1950s by scientists interested in creating artificial water. Since then, reverse osmosis has continued to be used for this purpose, as well as other applications such as cleaning goldfish tanks and water bottles. Although some purists argue that water filters with single filter pads can remove all contaminants, recent scientific studies have shown that a two-stage system using multiple filters can significantly reduce or eliminate most common contaminants found in tap water.
