Home Water Filter Systems




Home Water Filter Systems helps to filter the supply water from various contaminants and make it suitable for drinking, bathing, cooking and other essential household works. But whether the homeowner need one or not, depends on the quality of their local water supply. Local supply water, either tap or well water may be contaminated with various toxic microorganisms, metals, organics or chemicals such as E. Coli, Cryptosporidium cysts, lead, chlorine and chlorinated by products etc. Sometimes, the supply water quality may be good for the average population but not so good for the sensitive ones like elderly, pregnant women and children. In such cases using home water filter systems are definitely beneficial.

Steps to Choose a Home Water Filter System:

The key of selecting a water filter system for home depends on its purpose and point of usage. As different filters have different contaminant’s removal capability, we need to know the contaminants in our supply water first. This can be done by getting information of local water quality data or get the water independently tested from a certified laboratory.

Once the water quality information is known, then we have to decide which contaminants we like to reduce. Is it the taste, odor or the excessive amount of chlorine that bother us; or may be the water is unsafe due to high amount of heavy metal or other toxic chemicals like lead, arsenic etc.

The next step is to finds out various filter systems that can reduce the target contaminants as not all filters are suitable to reduce all contaminants.
