There is not any single water purification systems that can reduce all the impurities found in todays water supplies. This is why home water purifier systems are become more popular. They are your last chance to purify your water before using it for drinking, cooking and showering.

Home water treatment systems are divided into two broad categories. Point-of use (POU) and point of entry (POE). The POU systems are cheaper and usually easier to maintain than POE units.

POU systems are usually installed in the kitchen and bathroom. Counter top and faucet mount filters attach to the sink faucet by replacing the aerator with a simple diverter valve, aerator combination. Giving you the option for filtered or unfiltered water as you need it. These systems are easy to install and filter replacement is easy as you can stand at the counter to replace them. The only draw back to counter top filters is they take up some of your counter space.

Under counter systems usually take a little more time to install. You will need to do a small amount of plumbing changes to the cold water line feeding the sink and installation of the new single faucet used to get filtered water. The new faucet can be installed in an existing hole in the sink or you can drill a new hole to install it. These systems can be beneficial if you do not want to loose counter space. The only draw back is replacing the filters. Leaving extra length on the supply lines can make this process easier.

Pour through filters work on gravity, fill the upper compartment with water and it slowly filters it’s way in to the lower compartment. These systems are the easiest to install. They do take up counter space and the filters may not last as long as the other choices.

Shower filters reduce contaminants that can vaporize while you are showering. While they may not reduce as many contaminants as the other systems. The reason for this is the water does not have enough contact time with the filter to reduce them.

There is a wide variety of home water purification methods available. These include activated carbon, ion exchange, reverse osmosis, distillation, chemical oxidation and ultraviolet radiation treatment and systems that may include more than one of these processes. These processes purify water by either removing the contaminants or transforming them into less objectionable compounds.
