What Is a Faucet Aerator?

A faucet aerator is a small device attached to the end of bathroom and kitchen sink faucets. It consists of a mixer screen, a collar, and a neoprene gasket. Some aerators also include a plastic or metal disk with a small hole to restrict water flow to a water-saving 1.5 GPM (gallons per minute). All modern bathroom and kitchen sink faucets come with aerators.

The primary purpose of a faucet aerator is to:

• Reduce water usage
• Limit splashing
• Enhance water taste by introducing air

Aerators are not necessary for garden hoses, exterior hose bibs, shower faucets, or bathtub faucets.

Why Do You Need an Aerator?

Faucet aerators play a crucial role in improving the quality of your water flow and enhancing your overall faucet experience:

• Softer Water Flow: Aerators introduce oxygen bubbles into the water, creating a softer and more pleasant water flow.
• Wider Water Stream: Aerators widen the stream of water, making it easier to rinse dishes or wash your hands.
• Reduced Splashing: Aerators help limit splashing in the basin, keeping your countertops and floors dry.
• Water Savings: Aerators restrict water flow, reducing water consumption without compromising water pressure.
• Faster Soap Activation: Aerators help activate soap faster, making it more effective.
• Fresher-Tasting Water: Aerators introduce air into the water, resulting in fresher-tasting water.
• Sediment Removal: Aerators can help remove sediment from your water, improving its clarity and taste.

Signs You Need a New Aerator

It’s generally recommended to clean your faucet aerator twice a year and replace it once a year. Here are some signs that indicate you may need a new aerator:

• Restricted water flow
• Clogged aerator
• Sediment buildup
• Cracked or frayed gasket

Step-by-Step Instructions for Replacing a Faucet Aerator

Materials:

• New faucet aerator
• Towel

Tools:

• None required

Steps:

1. Remove the Old Aerator:

   • Close the stopper on the sink basin.
   • Fold up a towel and place it in the sink to catch any dropped parts.
   • Turn off the faucet collar containing the aerator.
   • Turn the collar counterclockwise with your fingers.
   • If you cannot get a good grip, wet a washcloth and hold it over the collar as you turn.

2. Install the Aerator:

   • Knock out the old aerator and discard it.
   • Lay the faucet collar so that its threads are facing upward.
   • Carefully place the new aerator into the collar.
   • Ensure the mesh end of the aerator is facing downward.
   • Push the aerator tightly into the collar.

3. Install the Aerator Gasket:

   • Place the aerator gasket on top of the aerator, within the faucet collar.

4. Complete the Aerator Assembly:

   • A properly assembled faucet collar will have an aerator with its hole side facing upward.
   • The aerator will not work without its gasket.

5. Screw the Aerator in Place:

   • Use your fingers to tighten the faucet collar and aerator onto the end of the faucet.
   • Do not over-tighten.
   • Turn on the sink faucet to test.

Tips for Installing Faucet Aerators

• Use a towel to help unscrew the faucet collar.
• Always stop the basin to avoid losing parts down the drain.
• Never use a wrench to turn off the faucet collar.
• Never reuse an old gasket for an aerator replacement; always use the new gasket that comes with the aerator.

Troubleshooting Common Issues

How do I remove the aerator from my faucet if it does not have a collar?

If your faucet does not have a visible collar, you have a recessed aerator. Try to remove it using a flathead screwdriver. The edge of the screwdriver will fit into one of the notches of the aerator. Then give it a push and tug, and the aerator should be dislodged. If this doesn’t work, there are inexpensive faucet aerator removal tools to get the job done.

Are faucet aerators universal?

No, you cannot fit one size or type of aerator into just any tap. There are two sizes of aerators: regular and junior. However, there are male vs. female threads on faucets and aerators, and you’ll need to know what you have. Threads on the outside of your faucet are male, so you’ll need a female aerator. Interior threads are female, so you’ll need a male aerator.

How do I know what size my faucet aerator is?

Aerators come in two general sizes: regular and junior. A regular male measures 15/16 inches, and a regular female measures 55/64 inches. A junior male measures 13/16 inches, and a junior female measures 3/4 inches. Here’s a measuring hack: If your faucet is the size of a nickel, you need a regular aerator. If it’s a dime, you’ll need a junior aerator.
