Kitchen and bathroom faucet aerators are simple screw-in attachments designed to mix air into your water flow. Changing your faucet aerator will help you reduce water use in your home and save money on water bills. In fact, these fixtures can reduce a sink's water flow by 30%, saving an average household more than 500 gallons each year. Your faucet aerator flow rate, which is measured by gallons per minute or gpm, should be printed on the side of your aerator housing or on the aerator insert itself. New kitchen faucets typically come with a 2.2 gpm faucet aerator and a bathroom faucet should be 1.5 gpm or lower. If the flow rate is higher, your aerator should be replaced. Neoperl offers a large selection of WaterSense-certified aerators in different sizes, flow rates and stream patterns to accommodate most faucet styles. Some of their aerators also go one step further, offering unique and functional features to remedy special conditions found in geographical areas across the country, such as drought, hard water lime build up and pressure restrictions.
