What is the difference between whole-home filtration and an under-sink filter?

An under-sink or pitcher filter only treats the water at one faucet. A whole-home (point-of-entry) system treats every drop entering the house, so showers, laundry, appliances and every tap get filtered water. If you are concerned about chlorine in shower steam, scale in your water heater, or staining, whole-home filtration is the right tool.
