Do Shower Head Filters Work? The Honest Answer for Australians

Short answer: yes, shower head filters work — but how well depends on the type of filter and what’s in your local water. Here’s an honest breakdown of what they do, what they don’t do, and whether one is worth it for your home.

What’s Actually in Your Shower Water?

Australian town water is treated with chlorine and chloramines as disinfectants — which is necessary for safe drinking water, but less ideal for daily skin and hair exposure. When you shower in hot water, chlorine volatilises into steam, meaning you’re inhaling it as well as absorbing it through your skin.

The effects of regular chlorine exposure in the shower include:

• Dry, irritated skin — chlorine strips natural oils and disrupts the skin’s moisture barrier
• Dry, brittle hair — chlorine depletes the natural oils that keep hair moisturised
• Scalp irritation and dandruff — a dry scalp flakes more easily
• Faded hair colour — chlorine accelerates colour fade in dyed hair
• Aggravated eczema or sensitive skin — particularly relevant for children and people with skin conditions

How Do Shower Head Filters Work?

Most quality shower filters use one or more of these filtration media:

• KDF-55 — a copper-zinc alloy that removes chlorine and heavy metals through a redox reaction. Effective at hot water temperatures, which makes it ideal for showers.
• Activated carbon — removes chlorine, VOCs, and taste/odour compounds through adsorption. Less effective at high temperatures than KDF.
• Vitamin C (ascorbic acid) — neutralises both chlorine and chloramines. One of the few media that addresses chloramines effectively.
• Chlorgon — converts chlorine to chloride, effective at higher water temperatures.

Our Sprite shower filter range uses KDF and Chlorgon media specifically engineered for hot water performance — unlike carbon-only filters which lose effectiveness as water temperature rises.

What Results Can You Expect?

Most people notice a difference within the first week — softer skin, less scalp irritation, and hair that feels less dry after washing. People with eczema, psoriasis, or colour-treated hair tend to notice the biggest improvement. The shower glass also stays cleaner longer with reduced mineral and chemical deposits.

What shower filters don’t do: they won’t soften hard water (that requires a water softener) and they won’t remove bacteria from the water supply. For whole-home filtration including every tap, see our Whole House Water Filters Guide.

When to Replace Your Shower Filter Cartridge

Cartridge life depends on your household size and local water quality:

• Single person or light use: every 4–6 months
• Couple or moderate use: every 3–4 months
• Family or heavy use: every 2–3 months

Signs it’s time: returning skin or hair dryness, reduced water pressure through the filter, or visible discolouration of the cartridge. Browse our replacement cartridge range for compatible Sprite cartridges.
