A New Zealand Mum Sent Her Shower Water to a Lab. The Result Changed How Her Whole Family Showers.

Doctors have warned about it for years. She finally tested it herself — and what came back made her put a filter on every shower in the house.

It started with a smell she couldn’t place. A faintly chemical edge to the steam every morning — the kind you stop noticing until, one day, you do.

Hannah, a 38-year-old mum of two from the Waikato, had spent a small fortune on her family’s health. Filtered drinking water. Organic everything. So when her youngest kept getting dry, itchy patches after every bath, she did the one thing most of us never think to do.

She tested her shower water.

What came back stopped her cold

We’re told to worry about what we drink. Almost no one talks about what we absorb. But a warm shower opens your pores, and your skin — your body’s largest organ — drinks in whatever is in that water for 8, 10, sometimes 15 minutes a day.

Independent studies have now found microplastics in an estimated 94% of tap water tested across developed countries. Tiny fragments and synthetic fibres, shed from pipes, packaging and the environment, small enough to pass straight through municipal treatment.

And it isn’t only your skin. In a hot shower, the heat aerosolises the water. That cloud of steam you breathe in for the length of your shower? It carries whatever the water carries — chlorine vapour and ultra-fine particles — deep into your lungs.

“I assumed ‘town water’ meant ‘clean water,’” Hannah said. “It treats for bacteria. It was never designed to take out microplastics or the chlorine they add to kill the bacteria. I was rinsing my kids in it twice a day.”

The fix wasn’t what she expected

Her first instinct was a whole-house filtration system — thousands of dollars and a plumber. Then she found that the real exposure happens at one place: the shower head. And that most ‘shower filters’ on the shelf only soften hard water or knock back chlorine. Almost none are built to catch microplastics.

That search led her to PureFlow™ — a chrome inline filter that screws on between your shower arm and your existing head in about 60 seconds, no tools, no plumber.

What made it different was the 3-stage core, engineered specifically to capture microplastics down to 0.1 microns — alongside chlorine, heavy metals like lead and copper, rust and sediment:

1. Stainless mesh — traps rust, grit and larger particles.
2. KDF-55 media — neutralises chlorine and pulls out heavy metals.
3. Ultra-fine fibre membrane — the layer that captures microplastics and microfibres down to 0.1µm.

Then she saw the cartridge

Filtration claims are easy to make. Hannah is an evidence person. So after three months, she unscrewed the housing and pulled the spent cartridge out next to a fresh one.

“That brown-grey sludge,” she said quietly, “was going onto my children’s skin. Every single day. That was the moment I bought one for every shower in the house and three for my mother.”

What changed in two weeks

She didn’t expect to feel a difference. She did. Within a fortnight the dry patches on her youngest faded. Her own skin stopped feeling tight after a shower. Her hair, she swears, holds its shine longer.
