Have you ever been in a situation where you have too many choices but you are not sure which one will best fit your requirement? Most of us go through this problem once in our lives because we want nothing but the best for ourselves, our family and our children. The same rule applies when you want to buy a water filter system. There are different types of water filter systems available out there is the market and they work on different technologies. The common thing that all of them share is the fact that they are useful in removing the contaminants and killing the harmful bacteria.

One of the most popular water filter system principle is that of ion exchange. It is the most common process used in most of the water filter systems available in the market. On the basis of the principle, the water will pass through a bed of ion exchange material and this will remove the hardness of various minerals present in water thus making the water soft. The ion exchange bed consists of insoluble anions, which become electrically neutral due to the presence of sodium cations.

So if you are thinking of buying a water filter system then the most common aspect that you should look for is that the water purifier chosen by you should be able to remove contaminants like Chlorine, lead, volatile organic compounds (VOCS), disinfection by-products, organic contaminants, and trihalomethanes (THMs).

You need to be also extra careful about the purification process used by most of the water filter systems. One of processes that became popular sometime back is the reverse osmosis (RO) process. The technology uses filtration through a membrane where the water is forced to pass through tiny pores in a semi-permeable membrane. Reverse Osmosis removes almost 80% to 90% minerals and sometimes this also means that you will lose the good minerals too. Another major disadvantage is that it can recover only 5% to 15% of the total water. So there is wastage of at least 85% of the water. Another major disadvantage of the RO system is that it is unable to remove organic chemicals like solvents and pesticides. The process of reverse osmosis is also unable to remove different harmful dissolved gases like trihalomethanes and radon.

Hence you need to compare very closely the different types of water filtration systems available in the market and then make your choice. Whatever you choose remember that it will be the only wall between you and harmful contaminants.
