Shower Filter Myths: What’s True and What’s Not

There’s a lot of noise around shower filters — some of it accurate, some of it marketing, and some of it just wrong. Here’s a straight-talking guide to the most common myths.

Browse our shower filter range or see our Shower Filters Guide.

Myth 1: “Shower filters are unnecessary — Australian water is safe”

Partly true, partly missing the point. Australian town water is safe to drink — but “safe” and “good for your skin and hair” aren’t the same thing. Chlorine is used to disinfect town water and is effective for that purpose. In the shower, it strips natural oils from skin and hair with daily exposure. A shower filter removes chlorine — it’s a quality improvement, not a safety necessity.

Myth 2: “All shower filters are the same”

False. KDF filters remove free chlorine effectively. Vitamin C filters remove both free chlorine and chloramines. Carbon filters are less effective in hot water (heat degrades carbon performance). The technology matters — see our guide: Shower Filter Types Explained.

Myth 3: “Shower filters remove everything from the water”

False. Shower filters are designed to remove chlorine and some heavy metals. They don’t remove fluoride (that requires reverse osmosis, which isn’t practical in a shower), they don’t soften hard water the way a whole-house softener does, and they don’t sterilise the water. Be sceptical of any filter claiming to “remove all contaminants”.

Myth 4: “Shower filters reduce water pressure”

Sometimes true, often not. A clogged or low-quality filter can reduce pressure. Our Sprite High Output models are specifically designed to maintain strong flow. Replace the cartridge on schedule and pressure won’t be an issue.

Myth 5: “Shower filters are hard to install”

False. Most shower filters install in under 5 minutes with no tools. See: How to Install a Shower Filter.

Myth 6: “Shower filters are expensive”

False. Our Sprite shower filters start from around $50–$80, with replacement cartridges every 6–12 months. That’s less than $10/month for genuinely filtered shower water. Browse our shower filter range.
