Tankless Reverse Osmosis System

Meet the illiwater Tankless Reverse Osmosis (RO) System—the smarter, faster, and more stylish way to enjoy pure drinking water at home. Unlike old-school RO systems that clutter your kitchen with a bulky storage tank, this under-sink unit is tankless, cabinet-free, and designed to free up as much as 4 ft² of valuable storage space. Sleek, quiet, and efficient, it blends seamlessly into modern kitchens while delivering performance you can taste in every glass.

At the heart of our Tankless system is a 5-stage advanced filtration process. First, sediment and carbon pre-filters trap particles, dirt, and odors. Next, the ultra-fine RO membrane filters down to 0.0001 microns, removing heavy metals, pesticides, and contaminants invisible to the eye. Then, UV sterilization eliminates up to 99.9% of bacteria for added peace of mind. A unique alkaline mineral stage reintroduces calcium and magnesium, giving your water a naturally smooth, refreshing taste while promoting bone and overall health. Finally, a polishing filter enhances flavor—so every sip feels clean, crisp, and revitalizing.

With an 800 GPD (gallons per day) high-flow membrane, it fills a 250 ml glass in just 8 seconds. No more waiting for a slow trickle like traditional systems. And with an eco-friendly 2:1 pure-to-drain ratio, it wastes far less water—saving a family of four up to 19,000 litres per year compared to older models. That’s not just good for your wallet; it’s good for the planet.

The experience continues at the faucet. Our smart digital stainless-steel faucet gives you real-time TDS (Total Dissolved Solids) readings, filter life alerts, and system status—all at your fingertips. The touch-sensitive design and brushed finish elevate your kitchen’s look, while ensuring you’re always in control of your water quality.

Maintenance is easy, too. With filters lasting up to 12 months and a simple one-click replacement system, upkeep is quick and hassle-free. The entire system comes in an all-in-one installation kit, designed for a 30-minute setup—no plumber required.

Certified for safety and performance by NSF, and backed by a 5-year warranty plus a 30-day trial guarantee, illiwater makes upgrading your water a decision you can feel confident about.

This is more than just a filter. It’s freedom from wasted water, cluttered cabinets, and questionable taste. It’s health, speed, and design—all in one.
