Low-Flow Faucet Aerator

One way to save water is to install low-flow aerators on kitchen and bathroom faucets. They can be installed in minutes by screwing them into the end of faucets. While most aerators limit water to three gallons per minute, low-flow models are available for around $5 that can reduce the flow to as little as one GPM. This can reduce faucet water usage by almost 60%. Aerators can save energy as well, since they use less hot water.


When you’re thinking green, two items are at the top of everybody’s list: water conservation and saving energy. Of course, you also want to save money and, even though you may be concerned about the environment, you don’t want to go broke making major changes. This is an aerator, and you can get one for as little as five dollars. It injects air into the water stream of your kitchen or bathroom faucet; and, because the mixture maintains a constant pressure, you’ll have a full, steady stream of water flowing, but be using less water. An average aerator restricts water flow to just under three gallons per minute, but you can purchase one with a flow rate of only one gallon per minute. Installing these can reduce water usage by almost 60%, and, here’s the icing on the cake, because you’re using less water, it will also reduce your energy cost to heat that water.


  1. Great video. There are also ultra low flow aerators at .5 gallons per minute and I have heard their will soon be a .33 gallon per minute model. There are also swivel head low flow aerators which are great for the kitchen, they typically have a higher flow like 2.2 gallons per minute. Here is a link to a few http://www.faucetaerators.com/swivel-head-faucet-aerators-c-25.html you can’t buy them here but gives you an idea on what to look for at the hardware store.

  2. I would like to know if an aerator can help if the water pressure is low. Can you install an aerator to make it appear to have better water pressure? If so, will the lower the gallons per minute be the way to go?

    Where will I find out the response. Will it be emailed to me? This is the first time I am leaving a comment. Thank you.

  3. Low-flow aerators, are bizarre bordering on insane. I’m trying to find one that DOESN’T limit flow. All the packages actually BRAG about how little water they let through.

    The purpose of a faucet is to deliver water. Bragging about impeding that purpose is insane … setting a maximum of 0.33 gallons/minute … as if it is a wonderful thing. Why not 0.001 gallons per minute? Has anyone heard of turning the faucet knob lower?

    If someone needs to fill a sink and wants 3,4,5,10 gallons a minute so what?

    Low flow saves no water, unless people run their sinks continuously. Do people turn on their sinks without purpose and wander off? If so, low flow has a purpose. Otherwsie, it ONLY stretches out the time. Is human time worthless? Apparently so.

    “Gallons per minute” tells you two things: how much water and how much time. If you are nuts enough to want to reduce the water (the purpose of the faucet), it means you feel time is less important … and that your assessment of the unimportance of their time needs to be forced on the users of the faucet.

  4. Hi, I have really high water psi. I would like to reduce the flow on a Price Pfister 526 -50ss kitchen faucet. I have been unable to find a aerator water restictor for this faucet. Are there any inexpensive regulators that can be installed on the hot and cold flex supply lines?

  5. Hi Harry,

    We are contacting you to see if we can assist you in finding an aerator for your Pfister Kitchen Faucet. What “Collection” does your faucet belong to? (ex. Contempra, Hanover, etc.).

    If can identify this, we should be able to answer your question.
