H2O, popularly known as water, is definitely the most essential natural substance for our survival. It controls body temperature as well as aids metabolic process. Drinking around eight glasses of water daily is advised to maintain hydration levels of the body. People residing in warmer environments and sports athletes may need much more. The quality of water is as important as the amount. The quality of tap water has been declining gradually due to the existence of industrial pollutants, chemicals and several other toxins. Children, women that are pregnant and elderly people are at a larger threat of contacting illnesses if they consume polluted water. A good drinking water filter therefore becomes an absolute necessity for each and every household.

Under the sink water filter systems are the most commonly found among all of the versions of water filters available. These kinds of filters are mounted under the sink. Water that comes to the sink initially passes thru these filters. The actual filter traps all the impurities which are found in the source water and clean drinking water is dispensed to the sink through the different tap. The actual supply water, though presumed to always be clean, consists of many harmful materials. Some examples are industrial wastes, sediments inside water pipes along with other chemical compounds leeching into ground water. These substances can cause severe harm to human body. Water that reaches taps is standard ground water which is treated with Chlorine to remove and eliminate bacteria. Chlorine can be very harmful.

Under the sink drinking water filters may work in two methods - It may be a reverse osmosis filter or a carbon block filter. The reverse osmosis filters are costly and demand a complicated installation process. In comparison, carbon block filters are much easier to install and are also economical. These consist of a cartridge loaded with activated carbon, which blocks chlorine, various other herbicides as well as odors which are generally found in plain tap water. The reverse osmosis filter systems consist of a membrane through which only pure water molecules can easily pass. The remaining water molecules, in which mineral deposits and other substances can be found, flow away like waste. The reverse osmosis filter is actually considered to provide the purest water but in fact it removes even trace minerals which are naturally contained in drinking water and are also beneficial for human beings. The EPA recommends the carbon block filters.

Under the kitchen sink water filters tend to be more in demand in comparison to counter top filter systems, shower filters or even whole house filters. The very first reason is naturally the cost. These types of filters are boon in homes which have much less or even simply no space for a large counter top filtration system. The only real maintenance required is usually to change the cartridge routinely, which really is easy. The active carbon block filters which also include ion exchange ensure that almost 90% of the impurities are removed, leaving the essential vitamins and minerals undamaged. Additionally, it is practical since it saves the cost of purchasing bottled water for drinking and therefore safeguards environmental surroundings as well from getting spoilt because of the plastic bottles. There are different models available for every price range as well as space available.
