New: Swiss Engineer's $39 Invention Turns Any Shower Into Chemical-Free Pure Water
For years, homeowners have faced the same frustrating choice: spend $3,000+ on a expensive whole-house filtration system — or keep spending $200 a month on cosmetics trying to fix the skin & hair problems caused by contaminated tap water.
Neither option ever made sense to Martin Keller.
Keller (58) is a water purification engineer who spent 28 years designing filtration systems for pharmaceutical manufacturing in Basel. After taking early retirement in 2023, he finally tackled the project that had been nagging him for over a decade.
"I spent my career making sure water was pure enough for pharmaceutical injectables," Keller explains. "And every evening, I'd step into my own shower and smell chlorine before the water even hit my skin. Millions of people do the same thing every morning. The water coming out of your shower head is treated with the same chemicals they put in swimming pools. The problem isn't the water supply — it's that your shower head lets every one of those chemicals through."
That observation became the foundation for IonDrops — a compact, precision-engineered filtered shower head that is quietly disrupting the home water industry worldwide.
"The Filtration Has Existed for Decades. Nobody Bothered to Put It in a Shower Head."
Keller's insight came from his work on pharmaceutical water purification — the kind of labs where the water has to be cleaner than what you'd drink, because even a trace of contamination could kill a patient.
"Obviously, we're not purifying to pharma standards here," he says. "But the principle scales down beautifully. If you layer the right filtration media in the right sequence, you can strip chlorine, heavy metals, and chemical byproducts out of running water — at any temperature — using nothing but the water pressure already coming through your pipes."
After 11 months of prototyping and over 30 iterations, Keller finalized a patented three-stage design he calls Tri-Action Ionic Filtration. The result: a solid shower head — noticeably nicer than the plastic one it replaces — that screws onto any standard shower arm and transforms ordinary tap water into clean, filtered water.
No plumber. No tools. No electricity. No pressure loss.
The First Test That Changed Everything
"I installed the prototype in my own bathroom and turned on the shower," Keller recalls. "Within thirty seconds, I ran my hand under the water. It felt completely different — softer, smoother, like the water at a hotel when you're on vacation and you can't figure out why your hair feels better. The chlorine smell was gone. Completely gone."
His wife tried it next. She stepped out and said four words: "That's not the same water."
After two weeks, she told him her skin had stopped itching for the first time in years. She'd been spending $80 a month on moisturizers — she threw them out. After 30 days, he pulled out the filter cartridge and held it up to the light. It was brown. Dark, rust-colored brown — everything that had been washing over their skin, into their lungs as steam, every single morning.
His wife filmed it. Shared the video in a family chat. It was forwarded to friends, then neighbors, then a local health blog. Within three weeks, Keller had over 400 pre-orders — without spending a cent on advertising.
From Retirement Project to 50,000 Households
What began as a passion project has now reached more than 50,000 households across Europe, North America, and Australia. IonDrops has amassed over 18,000 verified reviews with an average rating of 4.8 out of 5 stars.
The scientific community took notice too — IonDrops was cited in Water Quality International as an example of "pharmaceutical-grade filtration made accessible to consumers."
"Most shower filters are just a plastic tube with loose carbon inside," Keller explains. "That's like putting your thumb over a hose — you change the direction, but you don't filter anything. Carbon loses over 70% of its effectiveness the moment your water gets above 85°F. Your shower runs at 104. IonDrops uses a three-stage ionic system that works at any temperature. The difference isn't just noticeable — it's measurable."
What Homeowners Are Reporting
Since its launch, IonDrops has received overwhelmingly positive feedback from a wide range of users.
One homeowner shared: "I installed IonDrops and the very first shower felt different — softer water, no chemical smell, like showering at a resort. Within ten days, the dry, itching skin I'd had for twenty years was gone. Gone. I threw out three bottles of prescription moisturizer."
Another user calls it a lifesaver for seniors: "I'm 73 and my skin has been cracking and bleeding for years — nothing helped, not the creams, not the dermatologist. IonDrops screwed onto my shower in under a minute. Within two weeks, my skin stopped splitting open. I actually cried. I wish someone had told me it was the water ten years ago."
A busy parent described the impact on her family: "My 16-year-old had eczema patches on both arms that wouldn't go away no matter what we tried. Over $600 at the dermatologist. I installed IonDrops on a Tuesday. Three weeks later, her skin cleared up. She actually asked to wear a short-sleeve shirt to school. I cried in the hallway. A $39 shower head did what $600 in medical bills couldn't."
No matter your budget, this review captures the value: "Between moisturizers, prescription creams, and dermatologist visits, I was spending over $200 a month treating dry skin. That's $2,400 a year — on symptoms. Since installing IonDrops, I use a basic drugstore lotion. That's it. Best return on anything I've bought for this house."
Users have also discovered unexpected benefits:
Healthier-looking hair — "My hair was brittle and thinning for years. After six weeks with IonDrops, my hairdresser grabbed my arm and said, 'What did you do?' It's thicker, softer, and growing back in places I'd given up on."
Better breathing in the shower — "I didn't realize how much chlorine vapor I was inhaling every morning until it was gone. The difference is like opening a window in a room you didn't know was stuffy."
It's also safe for sensitive skin, babies, and pets.
But is All the Buzz Really Justified?
So far, more than 50,000 units of IonDrops have been sold directly to consumers worldwide, even without the help of major retail stores. Every time the stock is replenished, the device sells out quickly due to the high demand.
And all thanks to word of mouth. Users were so struck by the brown filter after 30 days that they photograph it, share it, and tell everyone they know about it. The before-and-after photos practically sell themselves.
Many Users Describe IonDrops as a Fantastic Deal
"My shower went from smelling like a public pool to feeling like a spa — in under sixty seconds. For $39. The water is softer, my skin doesn't itch, redness is gone, and when I pulled the filter out after a month, it was dark brown. That was going into my body every morning. Never going back."
David M.
"I couldn't believe how simple it was. IonDrops came neatly packed, screwed right onto my shower in seconds, and the difference was immediate. No heavy equipment, no plumber, no complicated setup — just clean water from a tool that feels solid and built to last."
Karen C.
"I thought my dry skin was just aging. Turns out it was the water. IonDrops proved me wrong in less than two weeks. My skin is softer than it's been in a decade — without changing a single product in my routine. I've already bought two more for my kids."
