- Intelligent and Precision: This tankless RO system boasts a smart faucet to track water quality with real-time TDS monitoring. And its filter life reminder function can help you replace filters in time to ensure your drinking water quality. The 24-month RO filter lifespan saves you the hassle and cost of frequent replacement.
- Efficient Filtration: The reverse osmosis water filter can filter 800 gallons of pure water per day. By its 2:1 low drain ratio, this system can produce only one cup of wastewater for every two cups of pure water, which is ideal for daily drinking and cooking.
- Tankless Ease: This reverse osmosis water system has a compact and stylish look. Compared with the traditional tank RO system, it saves 70% undersink space. You can effortlessly replace the filters in 3s without moving the system or using any tools.

Excellent clean water from a very hard supply. The taste difference is incredible but I mainly bought for the health benefits. Easy enough to install with an excellent manual. Automatic tube clamps work excellent but I had to use a spanner to take the tubes out (to hold the plastic clamps down) but I'm happy with this secure solution. 10/10 Highly recommended!!!!
Easy to install and so far functions perfectly. The difference in water quality is night and day.
We have been drinking water from this X8 for a month now and can safely say the water is cleaner and a bit colder. It was fairly easy to install with a few hiccups but was solved with a few adapters. The only thing that puzzles me is the remineralisation filter I bought which was supposed to raise the TSD levels but instead it lowered the TSD by two points.
