Home water filtration system:
Americans spend billions of dollars each year for home water filtration system. According to the Water Quality Association, more than 4 out of 10 Americans use a home water filtration system. These systems range from simple pitchers costing less than $20 to sophisticated reverse osmosis water filter costing hundreds of dollars. Some people use a home water filtration system to improve the taste of their tap water. Others treat their water because of health concerns.While EPA does not endorse specific units,the Agency does set and enforce national standards for the tap water provided by public water systems.
Drinking water can reasonably be expected to contain at least small amounts of some contaminants. As long as those contaminants are at levels no higher than EPA standards,the water is considered safe to drink for healthy people. People with severely weakened immune systems or other specific health conditions,or those concerned about specific contaminants present in local drinking water, may wish to further treat their water at home or purchase high quality bottled water.
Before purchasing a home water filtration system, consider local water quality, cost and maintenance of the system, product performance,and certifications to make sure that the water filter will meet your needs.

Check local water quality first
Begin by learning as much as possible about your tap water. If you haven’t already received it,contact your local water supplier and ask for the annual water quality report (sometimes called a consumer confidence report). This report lists the levels of contaminants that have been detected in the water and shows how these levels compare with EPA’s drinking water standards.
Some contaminant levels remain constant throughout the year, while others vary according to season,weather,or from house to house.
E.g, lead typically occurs when it leaches from the lead pipes and solder that are in some homes. If you are concerned about a contaminant whose level may vary, consider getting your water tested (use a certified laboratory for the most reliable results).Use this information to help decide on a home water filter.
If your water comes from a household well,EPA recommends annual water testing for nitrates and coliform bacteria. In addition,check with your health department or local water systems that use ground water for information on contaminants of concern in your area.
From this specific information, you can determine which water filter will fit your need:
- Remove specific contaminants
- Take extra precautions because a household member has a compromised immune system
- Improve the taste of the water,or some combination of these concerns.
