Faucet aerators are simple screw-in attachments with wire screens that mix air into the water flow, reducing the amount of water needed to get the same pressure. In fact, faucet aerators do not just save water; they also reduce the natural gas and electricity cost involved with water heating. Faucet Aerators that feature the EPA WaterSense® label can save the average family 700 gallons of water per year, equal to the amount of water needed to take 40 showers. Also, since these water savings reduce demands on water heaters, households will also save enough energy to run a hairdryer 10 minutes a day for a year.
