The Home One uses reverse osmosis, one of the most comprehensive filtration technologies for drinking water. This significantly reduces many undesirable substances. Based on the process, it can also be assumed that other substances not individually tested are also reduced.

It is not recommended to drink completely demineralized water permanently. That's why we supply the Home One with a mineral filter as standard, which re-adds important minerals to the water. Alternatively, the device can also be operated with the MN filter, which does not mineralize - for all those who want to mineralize themselves or use pure osmosis water.
The mineral filter adds the following minerals:
Potassium (K⁺) (mg/L): 1.7883
Sodium (Na⁺) (mg/L): 0.8125
Calcium (Ca²⁺) (mg/L): 21.8251
Magnesium (Mg²⁺) (mg/L): 2.1045
Yes, many water filters can be a breeding ground for germs if improperly designed or lacking hygiene. That's why the Home One is equipped with two UV-C lamps that treat the water before and after filtration. This significantly reduces the risk of contamination, even with long-term use.
The RO membrane should be replaced at least every 16 months. The pre-filter (CF) and the post-filter (mineral or MN filter) should be replaced at least every 12 months. Most of our customers replace their filters about once a year, incurring annual filter costs of around €90.
Compared to bottled water, the Home One is significantly cheaper in the long run. While bottled water often costs around €0.70 per liter or more depending on the brand, a liter from the Home One, including purchase and filter replacement, costs about €0.15. In addition, there's no more carrying heavy crates, and water from plastic bottles can contain microplastics if stored for a long time.
Compared to pitcher filters, the filtration is significantly more comprehensive. This allows for the reduction of substances that a classic pitcher filter often doesn't reliably retain.
Yes. Instead of the mineral filter, the Home One can also be used with the included MN filter. This does not mineralize the water and is suitable for anyone who wants to mineralize themselves or drink pure osmosis water.
“For twenty years I kept putting off the issue. Old pipes, news in the press, but I never took action. When I tasted osmosis water for the first time at my daughter's house, it was a flavor explosion. In the test report, the Home One was number one, cheaper than devices costing over a thousand euros. I would buy it again every day.”
“When the reports about PFAS came out, I researched for a week and a half. The only answer that kept coming back was that reverse osmosis is the only thing that really removes PFAS and microplastics. Since we got the Home One, the topic of drinking water is settled for us. We no longer carry crates and love our water. My daughter even voluntarily drinks more water now.”
"I'm surprised how well it works. I used to have a pitcher filter, a separate descaling filter, and a faucet filter, and the water still wasn't clean. Everyone tried to sell me built-in systems for three thousand euros. The Home One filters at least as well, simply sits on the countertop, and replaced everything in one device. God knows this market is full of people who want to sell you all sorts of things for thousands of euros."
Guests are thrilled! We had guests over the weekend, and when they tasted our water, they immediately exclaimed: What is this? It's amazing. My wife is just as thrilled; she says the glasses are truly sparkling for the first time. We both drink much more than before. Healthy water that tastes good isn't that common.
I live in an old building from 1970 and have always wondered what might be getting into the water through the old pipes. When reports of PFAS in Berlin tap water came out, I spent days pouring boiled water through coffee filters into glass carafes. The grime that collected in the carafes was unbelievable. Since the Home One has been installed, I'm truly impressed. THE WATER IS CLEAR. No residue!

Real results from Home One owners
I was sure our older building had lead pipes — the water always smelled metallic. Since the Home One, that's gone. Fresh, soft, and my son actually drinks way more water now.
I've researched water filters for years and I'm picky. My tap measured 290 ppm; after the Home One it's a stable 16. With PFAS and heavy metals in the news, that peace of mind is worth it.
Plumbers wanted $3,000 for an under-sink system. The Home One sits on the counter, needs zero installation, and filters just as well. Total no-brainer.
Coffee nerd here. I did a side-by-side: tap vs. Home One. The filtered shot had real crema and way less bitterness. There's no going back.
We stopped buying cases of water completely. It tastes incredible, and we're not hauling plastic up three flights of stairs anymore.
We rent, so an installed system wasn't an option. This just plugs in — cleaner water in seconds and it looks great on the counter.
I'm 55 and started reading about PFAS, nitrate and microplastics in our water. After a lot of research I went with HO3 — the mineral filter sold me, I didn't want flat, empty water.
Near-boiling water for tea and coffee on demand, no kettle needed. Honestly use it ten times a day now.
We're in a hard-water area and limescale was ruining everything. Gone now — and the glasses are crystal clear for the first time.
Water quality is fantastic and setup took five minutes. The tank can drip a little when you refill if you're not careful — minor, honestly, compared to how good the water is.
