How to Install a Faucet Water Filter – Step by Step Guideline

Installing a water filter is a pretty straightforward process that you can usually do in just a few minutes.

Step 1 – Check the Kit

Before you start to install your filter, it’s important to check the contents of the filter for all the necessary pieces you need. The base is the most essential part, so if this is broken, you should look for a replacement.

Your filter kit should also have a replaceable filter cartridge along with some adapters and washers since everyone doesn’t own the exact same faucet type.

Step 2 – Twist Off the Aerator

Grab your faucet’s aerator with your thumb and first two forefingers to twist it clockwise and unscrew it. If you see any rubber washers beneath the aerator after you removed it, peel those off too. You can grab the aerator with a dry towel if you have difficulty removing it with your bare hands.

Step 3 – Clean Off Buildup

Make sure to check your faucet for any limescale or rust buildup so you have an easier time attaching the filter. The safest way to remove limescale and rust is by using vinegar.

Fill up a plastic bag with white vinegar and place it over the faucet. Use a rubber band to hold it in place and make sure that the vinegar completely covers the buildup. After letting the faucet sit in the vinegar for about an hour, remove the plastic bag and then run warm water. To get rid of any buildup residue, you can use a sponge or an old toothbrush.

Step 4 – Attach an Adapter

You usually need an adapter if your faucet has threads on the inside, but you don’t if it has threads on the outside. You’ll be able to figure out which adapter is compatible with your faucet by simply comparing the size of the adapter to the size of your faucet.

Best Faucet Water Filter

After you’ve found the correct one, carefully place the washer into the recessed end of the adapter by gently pushing it with your index finger.

It should fit comfortably so you can easily twist the adapter onto the faucet. As you do this, align the threads of the adapter with the faucet threads and then twist in a counterclockwise direction to firmly attach the adapter.

Step 5 – Attach Filter System

Depending on what kind of filter you have, position the base system below the faucet with the filter cup part on the left side. Afterward, twist the mounting collar on until it’s a snug fit.

Lastly, attach the cartridge by pushing it down until it clicks and then flushes the system by running cold or warm water for 5 minutes through the faucet. After this step, your filter should be ready to use.

Final Verdict

Whether you install it directly on your faucet or underneath your sink, a faucet water filter is designed to remove harmful contaminants from your kitchen sink’s tap water which makes your water cleaner and safer to drink.

It also saves a lot of money in the long run since you don’t have to constantly buy bottles of water and filter cartridge replacements can be relatively inexpensive.

Hopefully, our list above helps you find the best water filter faucet for your sink so you can enjoy clearer and better-tasting water for you and the whole family to drink.
