Advanced 5-Stage Reverse Osmosis Water Filter System

Our tankless RO system with remineralization capability delivers pure and delicious water right from your faucet. Its thorough 5-stage purification with alkaline filters ensures your water is contaminant-free and mineral-rich with a balanced pH.

Let’s walk you through the 5-stage reverse osmosis water filtration process.

Stage 1: Sediment Filter: The first stage comprises a high-performing polypropylene sediment filter that removes visible impurities such as rust, silt, sand, and dirt. The pre-filtration stage protects the filters against clogging, improving their efficiency and longevity.
Stage 2: Carbon Filter: Next, an activated granular carbon block absorbs chlorine, volatile organic compounds (VOCs), chloramines, and other harmful chemicals from the water. This step strips the water of unpleasant tastes and odors and also safeguards the RO membrane against oxidant damage.
Stage 3: RO Membrane: After that, the water moves through the semi-permeable RO membrane. Its incredibly fine 0.0001-micron pores execute filtration on a molecular level. As a result, the water is pure of up to 99% TDS and contaminants such as fluoride, nitrates, arsenic, lead, and other toxic organic and inorganic compounds.
Stage 4: Alkaline Remineralization Filter: The fourth stage consists of a cutting-edge alkaline filter that recuperates minerals such as magnesium, calcium, and potassium into your water. The mineralized water is not only great for your health but also has a balanced pH and refreshing taste.
Stage 5: Post-Carbon Polishing Filter: The last stage uses a high-density carbon block to further refine the water. It captures any leftover tastes that may have crept back into the water after its remineralization. The instant you open the faucet, you get crystal clear and hygienic water.

More Room Under Your Sink

Our tankless reverse osmosis system with a sink faucet features a futuristic, space-optimizing design. It preserves valuable cabinet and counter space by easily tucking in the cabinet under the sink. The tankless RO system’s state-of-the-art technology guarantees you fill a standard glass in only 8 seconds.

DIY Installation: The package contains a DIY installation kit comprising color-coded, quick-connect hardware and connectors. It also consists of single-click cartridges that make routine maintenance simple and tool-free.
NSF/ANSI Certified: Our tankless RO water faucet filter for sink is NSF/ANSI 58, 42 & 53 certified. This independent certification validates that the system is safe, reliable, and effectively eliminates hazardous contaminants.

What does "tankless" actually mean, and why does it matter?

A tankless reverse osmosis system filters water on demand — the moment you open the tap, rather than storing pre-filtered water in a pressurized tank. This means you never wait for a tank to refill, you always get fresh filtered water, and you free up roughly 4 square feet of under-sink cabinet space. It also eliminates the risk of water sitting stagnant in a tank for extended periods.

How fast does the Tankless RO System dispense water?

The system runs at 800 gallons per day, filling a standard 250ml glass in around 8 seconds. That flow rate makes it practical for large families and busy households. You can run it continuously for cooking, filling kettles, and drinking without it struggling to keep up. If you'd like to compare flow rates across the range, see the full reverse osmosis systems page.

What does the smart digital faucet actually show me?

The touch-sensitive stainless steel faucet has a built-in screen that displays your water's TDS (total dissolved solids) reading in real time, so you can see the purity level with every pour. It also monitors filter usage and sends alerts when a replacement is due — no guessing or calendar reminders needed. Just tap anywhere on the faucet to start or stop the water flow.

Does the Tankless system add minerals back into the water after filtering?

Yes. Stage 4 of the 5-stage filtration process is an alkaline remineralization filter that reintroduces calcium, magnesium, and potassium into the water after the RO membrane removes contaminants. This balances the water's pH, improves the taste, and ensures you're not drinking demineralized water, a common concern with standard RO systems that skip this step.

How often do the filters need replacing, and what does maintenance involve?

Filters last up to 12 months for an average-sized family, and the RO membrane needs replacing every 2–3 years. Cartridge replacement is tool-free with a twist-and-lock design, and the smart faucet display alerts you when a replacement is needed. There's no guesswork, and the whole process takes just a few minutes.

Is the Tankless RO System suitable for an apartment or a small kitchen?

It's actually one of the best options for compact spaces. Without a storage tank, the unit is significantly smaller than traditional RO systems and fits neatly inside almost any under-sink cabinet. Installation takes around 30 minutes using the included colour-coded quick-connect fittings and pre-installed filters, no plumber required.

How quickly will my order arrive, and what's the return policy?

illi Water ships free to anywhere in Canada, with every order processed within 1–2 business days and tracking information sent once dispatched. The Tankless RO System comes with a 90-day satisfaction guarantee if it's not the right fit. Return it in its original packaging with all components for a full refund. A 5-year limited warranty also covers defects in parts and workmanship from day one. Email support@illiwater.com to arrange a return or warranty claim.
