A faucet aerator is an inexpensive, easy-to-install circular metal device with a screen that screws onto the end of the faucet. As the name implies, a faucet aerator adds air to the stream of water coming out of the faucet by breaking the water into fine droplets. The most important benefit of a faucet aerator is that it conserves water. In fact, the U.S. Environmental Protection Agency says installing "faucet aerators is the single most effective water conservation savings you can do for your home."
Installing faucet aerators can reduce the water use at a faucet by as much as 60 percent. A flow rate of 2.5 gallons per minute is standard for a faucet aerator (compared to as much as 5 or 6 gallons per minute for a faucet without an aerator), but faucet aerators with a flow of as little as .5 gallons per minute are available.
Using faucet aerators to conserve water used in the home lowers the cost of heating water for washing dishes and other activities that require hot water.
Filters Out Small Debris
The screen in a faucet aerator filters out small debris in the water supply. The screen is easily cleaned if it becomes clogged with debris. Just unscrew the aerator from the faucet and rinse it out. A screen that is clogged by hard water minerals may have to be soaked in a fluid that dissolves calcium and lime.
Increases Water Pressure
If the water pressure at the faucet is low, installing an aerator will increase the pressure slightly.
A faucet aerator reduces splashing by slowing down the flow of water from the faucet.
More Dollar Savings
Installing faucet aerators saves money on water bills (which probably include a sewage component), wear and tear on well water pumps, and stress on septic systems.
