How to Attach a Brita Faucet Filter

Attaching a Brita faucet filter is a straightforward process that allows you to enjoy clean, filtered water directly from your kitchen sink faucet. Whether you’re concerned about the taste or quality of your tap water, installing a Brita faucet filter provides an easy solution. In this guide, we’ll walk you through the steps required to attach a Brita faucet filter to your kitchen sink faucet, ensuring a secure and reliable installation.

1. Gather the Necessary Tools and Materials

Before you begin the installation process, gather the following tools and materials:

  • Brita faucet filter kit
  • Adjustable wrench or pliers (if necessary)
  • Clean cloth or sponge
  • Teflon tape (optional)

Having the right tools and materials on hand is essential for a smooth and successful installation. The Brita faucet filter kit typically includes all the components you’ll need, such as the filter unit, adapters, and installation instructions. Additionally, you may need an adjustable wrench or pliers to loosen the aerator on your faucet if it’s tightly attached. A clean cloth or sponge can also come in handy for wiping down the faucet and ensuring a clean surface for installation.

2. Prepare the Faucet

Start by turning off the water supply to the faucet you’ll be installing the Brita filter on. This is typically done by turning off the shut-off valves located under the sink. Once the water supply is turned off, turn on the faucet to release any remaining water pressure and allow the faucet to drain completely.

Properly preparing the faucet before installation is essential for a secure and leak-free connection. Turning off the water supply prevents any water from flowing while you work, reducing the risk of leaks or spills. Allowing the faucet to drain ensures that there’s no water trapped in the lines that could interfere with the installation process or cause a mess.

3. Remove the Aerator

If your faucet has an aerator attached, you’ll need to remove it before installing the Brita filter. Use an adjustable wrench or pliers to loosen the aerator by turning it counterclockwise. Once loosened, carefully unscrew the aerator by hand and set it aside for reattachment later.

The aerator is a small device at the end of the faucet spout that helps regulate the flow of water and prevent splashing. Removing the aerator allows you to access the faucet’s threading, where the Brita filter adapter will be installed. Take care when removing the aerator to avoid damaging the threads or any surrounding components.

4. Install the Brita Faucet Filter Adapter

Next, take the Brita faucet filter adapter and screw it onto the threaded faucet spout in place of the aerator. Ensure that the adapter is securely tightened by hand, but avoid over-tightening, as this could damage the threading or the adapter itself.

The Brita faucet filter adapter is designed to fit most standard faucet threads, providing a secure connection for the filter unit. Simply screw the adapter onto the faucet spout in place of the aerator, ensuring a snug fit by hand. Take care not to over-tighten the adapter, as this could strip the threads or cause damage to the faucet.

5. Attach the Brita Filter Unit

Once the adapter is securely installed, it’s time to attach the Brita filter unit to the adapter. Simply press the filter unit onto the adapter until it clicks into place, ensuring a tight and secure connection.

The Brita filter unit is designed to snap onto the adapter with ease, providing a secure and leak-free connection. Simply align the filter unit with the adapter and press firmly until you hear a click, indicating that it’s properly seated. Take care to ensure that the filter unit is aligned correctly to prevent any leaks or malfunctions.

6. Flush the Filter

After attaching the Brita filter unit, run cold water through the filter for a few minutes to flush out any air bubbles and activate the filter media. This helps ensure that you’ll get clean, filtered water right from the start.

Flushing the filter is an important step in the installation process, as it helps remove any air bubbles and activate the filter media for optimal performance. Simply turn on the cold water and let it run through the filter for a few minutes, allowing the water to flow freely and flush out any trapped air or debris. Once the water runs clear, your Brita faucet filter is ready to use.


Attaching a Brita faucet filter is a simple and effective way to enjoy clean, filtered water directly from your kitchen sink faucet. By following the step-by-step instructions outlined in this guide, you can easily install the filter unit and start enjoying the benefits of cleaner, great-tasting water in no time.
