Generally we take the tap water for granted. We think it to be pollutant free as it comes from a deep well or a municipal water supply. Unfortunately this is not a right assumption always. Both well and municipal water are occasionally found to contain coliform bacteria or parasite cysts. Some times the water may contain some sedimentary particles. Consequently it is important to have a water filter installed to filter out all such impurities.

Different types of water filters are efficient in removing different types of impurities. Most popular water filters available in market are faucet mounted water filters, undersink water filters, counter top water filters, reverse-osmosis water filters, activated carbon water filters and whole house water filters. Choose one according to the impurities present in water coming into your house.

Faucet mounted water filters can be conveniently installed and do not require much space in your kitchen. They are considered to be very effective in reducing the chlorine level, sediment and rust from water. Its installation is quite simple and is not very expensive. You can purchase this water filter by spending $20-$70.

The advantage of whole house water filters is that they address the needs of the entire home. They are ideal for removing rust, sedimentary particles and even chlorine from tap water. However they typically do not effectively address other pollutants such as metals, Volatile Organic Compounds (VOC), parasite cysts and coliform bacteria.

You need to hire a plumber for installing this water filter in your house as its installation is quite complicated. You need to install it along the main water supply line of your house. This water filter will cost you between $40 to $1000 (small one between $50 and $100).

Reverse-Osmosis water filters can effectively clean water and eliminates most of the pollutant present in water to make it safe for drinking. Most of the impurities present in water such as arsenic, cysts, heavy metals, rust, Chlorine, Sodium and dissolved solids are removed by use of this filter. Installation of this filter is not easy and requires a plumber for the same. For obtaining this type of water filter, you need to spend $200-$600 which is quite high as compared to other water filters present in market.

Undersink water filters are considered to be efficient in removing rust and sediment out of water. They also improve the taste and odor of the water. They are big in size and require considerable space in the kitchen. They can be obtained by spending $30 to $400.

So before purchasing a water filter, have your water tested first to see what water filter type is right for your specific water needs.
