Here's an easy way to live a little greener and save a little money: install low-flow faucet aerators in your home. Now, don't worry. "Low-flow" does not mean you'll be washing your hands under a puny trickle of water. Nope. That's because the aerator is like a tiny sieve that mixes air into the water stream. You won't even notice you're using less!

Was your home built prior to 1989? Do the fixtures date to that era or earlier? Then chances are high your faucets need the addition of aerators. Turn on the cold water and observe: does the water gush out fast and unrestricted as, say, water from your garden hose might? Or does it flow fast, yet feel somewhat lighter and fizzier in your hands?

If it's the former, you probably need aerators. Unscrew the faucet spigot (the nozzle where the water comes out) to double check. The latter means you probably have them already.
