This system, also known as point-of-entry, filters your water as it comes into your home. All the water used in your home, whether for bathing, washing or drinking, is filtered. If sediment in your water is a problem, this system can help remove it and prolong the life of your major appliances that depend on water, such as your water heater, dishwasher and washing machine. However, this system usually will not remove dangerous health pollutants.
Make sure the system is certified for the contaminants you want removed. Most whole house systems are not effective in removing lead and chloroform.
Whole house filters can cost about $250 for purchase and installation with inexpensive, long lasting filtering cartridges.
