How to Replace a Faucet Aerator: A Comprehensive Guide
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

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.
