Introducing the all new Hommix hydRO-1K

A breakthrough in water filtration technology that will revolutionise the way you experience pure, refreshing, crisp water, whether you're at home or work. This innovative product is a fully automatic direct flow under sink Reverse Osmosis (RO) system designed for maximum convenience and performance.

Unmatched Performance!

At the heart of the hydRO-1K is its impressive 1000 Gallon Per Day (GPD) membrane. This remarkable feature ensures a continuous flow of crystal-clear water at your fingertips. Thanks to its cutting-edge 1000 GPD booster pump, you'll enjoy rapid water dispensing with an impressive flow (approx. 2-2.5L per minute), meeting even the most demanding hydration needs.

Innovative Space-Saving Elegance!

The hydRO-1K is not only a powerhouse but also a space-saving marvel. Its sleek and stylish design makes it one of the most compact RO systems on the market at only 14cm wide. It fits seamlessly under your sink, leaving your kitchen or workspace uncluttered. Say goodbye to bulky, inconvenient water filtration systems with additional tanks.

Effortless Maintenance Like No Other!

We've made maintenance a breeze with the hydRO-1K. Say goodbye to complicated filter replacements. This system features three super-easy quick-change filters. Simply press a button, and the filter pops out, making replacements a cinch. Filters 1 and 3 are replaced every 6 to 12 months, while the second filter (RO membrane) is replaced every 24 to 36 months. The lifespan of the filters can vary based on location, as water quality isn't the same for every household. Therefore, the suggested timeframes are only guidelines; the system will notify you when it's due for a filter replacement via the LED indicators and beeping.

The hydRO-1K doesn't just purify your water; it enhances it. With five stages of filtration, including the final stage with added activated coconut shell carbon and pH adjuster using iron ions for a more alkaline, when you're after that perfect finish, you can trust that every drop of water is pure and refreshing.

Super Easy Installation!

You don't need to be a plumbing expert to enjoy the benefits of the hydRO-1K. Our user-friendly installation process is designed with you in mind. The comprehensive instructions along with all the required fittings & parts will have your hydRO-1K connected and ready to use in no time. Plus, the elegant 304 stainless steel single water dispensing tap is given to dispense the filtered water, if you wish to go for a 3-Way Tap to add a touch of sophistication to any setting and avoid drilling a new hole for the additional tap, we'll give an automatic discount at the checkout (10% off your 3-way tap)!

Hommix hydRO-1K - 1000GPD Under Sink Tankless RO System With Alkaline + Savona Brushed Nickel Pul...

Before installing the hydRO-1K - 1000GPD our tap water (from Affinity Water) tasted OK, but we knew that R.O. water could taste better.

We considered a few of Hommix's products, but went for the tankless system mainly because it seems so easy to self-service. It's also compact and, let's face it, has a stylish, high-tech appearance which in many homes is likely to be hidden under the sink — more's the pity!

We also thought that the three-filter system was going to give us high-quality water, and now that we've had the system for a few weeks we aren't disappointed! I'm reminded of the fantastic mountain water I last tasted in north Wales! It's somehow just that bit sweeter than without the system but still has no noticeable flavour at all! Even my cup of tea tastes a lot better — just a lot more like tea!

We also chose the Savona Pull-Out Spray-Hose 3-Way tap. This is not essential and may seem somewhat pricey but, as well as the high quality of the material which suggests it should be trouble-free for a long time, we also like other features. The Pull-Out hose makes it really easy to fill individual dishes and mugs for soaking no matter where they are in the sink, and the spray feature makes rinsing dishes more affective. It is also designed in such a way that you can operate it without touching any of the leavers with dirty or wet hands (i.e. back of the wrist) which means that it doesn't accumulate grime; so it's a while before any of its parts will need a good scrub, if at all.

Very professional, efficient and great value. We purchased two units and both were installed within the hour. They replaced our old system with much more functional and faster units. More compact and just a better looking machine. Grateful for all they did.
I would recommend both the machine and all the people behind the scenes. Thank you!
