## Description

First-to-market RO system with heating. Dispense hot water 40-95Â°C, 5-stage filtration to reduce TDS, chromium, PFAS. Tankless, smart LED faucet for clean water on demand.

Review: Excellent RO water system! - It purifies water thoroughly, and while the initial taste was slightly bitter due to extensive TDS removal (expected with any high-quality RO purifier), adding a remineralization filter made the water wonderfully sweet and enjoyable to drink. Even my dog prefers this water! After experiencing this, tap water just doesn’t compare anymore. As a doctor, I installed this to ensure better health, especially with recent news suggesting that 70-80% of UK water might be unfit for consumption. The smart tap is a standout feature—sleek, efficient, and definitely an eye-catcher. My family and friends were so impressed after tasting the water and seeing the setup that many have installed the same system. Highly recommend it for anyone serious about clean and great-tasting water!"
Review: Great product. - Easy setup, works great. Filter clean from 240 tap water to 15, but screen on tap show 7. And also before was worse tap water around 340 and result was the same

### ⭐⭐⭐⭐⭐ Great product.
*by B***N on 8 December 2025*

Easy setup, works great. Filter clean from 240 tap water to 15, but screen on tap show 7. And also before was worse tap water around 340 and result was the same

### ⭐⭐⭐⭐⭐ Overall happy, Vender support is responsive, water quality is good, Instant Hot water is useful.
*by C***H on 29 December 2025*

All in all happy. Instant Filtered hot water is very useful TDS started ~20 & went up to ~50 after ~6 months. A replacement filter returned it to ~15 & rose to ~38 after 11 months. Another issue was E06/E05 errors ~ 20 months in. I contacted Water drop & they agreed to ship a replacement if I paid £90. The replacement came with a new filter so was les than a filter for a new machine. whilst I was miffed at paying £90 the prospect of paying less than a new filter around the time it was due to replaced & getting a new machine made sense. Didn't take long to swap the old for the new.
