How to Install a Shower Filter: Step-by-Step Guide

Installing a shower filter is one of the easiest home improvements you can make — no plumbing, no tools beyond a pair of pliers, and it takes under 5 minutes. Here's exactly how to do it.

What You'll Need

• Your new shower filter
• Plumber's tape (Teflon tape) — usually included
• Adjustable pliers (optional — hand-tight is usually sufficient)
• A bucket or towel for any drips

Step-by-Step Installation

Step 1: Remove Your Existing Showerhead

Turn off the water. Using pliers (wrap the jaws with a cloth to protect the finish), unscrew the showerhead from the shower arm by turning anticlockwise. Set the showerhead aside — you'll reattach it to the filter in Step 5.

Step 2: Wrap the Shower Arm Threads with Plumber's Tape

Wrap 2–3 layers of plumber's tape clockwise around the male threads of the shower arm. This creates a watertight seal and prevents leaks. Don't skip this step.

Step 3: Attach the Shower Filter to the Shower Arm

Thread the shower filter onto the shower arm by hand, turning clockwise. Hand-tight is usually enough — if the filter has a hex nut, use pliers to snug it up a quarter turn. Don't overtighten.

Step 4: Flush the Filter

Before attaching your showerhead, turn on the cold water and let it run through the filter for 30–60 seconds. You may see slightly discoloured water initially — this is normal carbon residue from the new cartridge and is harmless. Run until the water runs clear.

Step 5: Reattach Your Showerhead

Wrap the filter's outlet threads with plumber's tape, then thread your showerhead onto the filter clockwise. Hand-tight is fine. Turn on the water and check for leaks around both connections. If dripping, snug up slightly with pliers.

Step 6: Enjoy Filtered Shower Water

That's it. Your shower now delivers chlorine-reduced, filtered water. Most people notice softer skin and less hair dryness within the first week.

Benefits of Filtered Shower Water

• Softer skin — chlorine strips natural oils; removing it lets your skin retain moisture
• Healthier hair — less dryness, less frizz, and colour-treated hair lasts longer
• Less scalp irritation — particularly beneficial for eczema, psoriasis, and sensitive skin
• Cleaner shower glass — fewer chemical deposits means less scrubbing
• Better air quality in the bathroom — less chlorine volatilising into steam

When to Replace the Cartridge

Most Sprite shower filter cartridges last 3–6 months depending on household size and water quality. Signs it's time: returning skin dryness, reduced flow, or visible discolouration. Browse our replacement cartridge range for compatible Sprite cartridges. Also see our Whole House Water Filters Guide if you want filtered water from every tap.
