In the beginning of the last century, many city and municipality suppliers began chlorinating supplies of water in an effort to combat liquid-borne pathogens, such as cholera and typhoid. While the chlorine did help lower these sicknesses, people did start to suffer from other health issues. Some attributed these complaints to the recently chlorinated supply. Using under-sink water filters goes some way to preventing medical issues.

Over the years many people have sought out treatment options for their water supply before bathing in, or drinking it. Many cities and municipalities still chlorinate their drinking water supplies, even with growing public unease and distrust of its safety. Because of their perception of the dangers, many homeowners are using their own water filters to filter out this substance before it flows from their taps.

For people who live in areas with high concentrations of chlorine, a whole home filtration system is often the best choice. These whole home filters treat all of the home/business/etc supplies. This method of treatment is most often done through reverse osmosis which greatly reduces any impurities or additives in the supply.

Those living in places where the levels are in the mid-range, often do not need to go to the cost of whole house filtration as it is not usually necessary. Instead, a filtering system on just the home's drinking supply is a simpler way to go. This can be done through an on-tap filter, a separate filter pitcher, or through an in-line filtration system that is placed under the kitchen or bathroom sink. Advanced reverse osmosis systems can filter to 100% purity using special membranes that won't even allow any bacteria or viruses to get past.

For areas where very little chlorine is added to the water supply, or for people not wishing to go to the expense of other filtration methods, there are some options including boiling it for a few minutes, or putting a pot full of water out in the sun for a few hours. Obviously, these methods have some drawbacks and need more effort, but they are the cheapest options available to rid it of any chlorine. The chlorine will evaporate in the heat of the sun or by boiling.

If showering and bathing water has chlorine, it can also be harmful to one's health. The chlorinated liquid deposits toxins onto the skin which can then be absorbed into the body. To combat this, special shower heads and faucets can be installed which effectively filter it out, and they are relatively simple to install.

The removal options that a homeowner picks largely depend on how determined they are to get rid of it, how much of the chemical is actually in the liquid, and the amount of money, if any, they are willing to pay for the best water filters. For those just wanting a few gallons for drinking purposes, the boiling method may be best. For others who want every drop inside their home to be contaminant free, a whole home filtration system is the way to go.

Chemicals and impurities in your supply are just a way of life, so use the best water filters you can afford. There really is no municipal or city drinking source on earth that is completely free of them. Thankfully, there are options available, from those which are free to those costing thousands of dollars, that effectively remove all the chemicals and contaminants.
