Smart Temperature Control: Instant Enjoyment

  • Multi-Stage Water Temperature Selection: Through the smart faucet, you can easily choose from multiple temperatures, including 5°C icy cold, ambient, 45°C, 85°C, and 95°C, satisfying various daily needs for brewing coffee, tea, or cooking. The internal heating element can reach approximately 98°C, ensuring fresh and rapid hot water supply.
  • Icy Cold Pure Water On Demand: The built-in powerful compressor can rapidly cool pure water in the cold water tank from 25°C to a refreshing 5°C within 25 minutes. With a 1.0-litre cold water tank capacity and a cold water dispense rate of 1.0 litre per minute, you can enjoy icy cold pure water anytime.
  • UV-C LED Sterilization: The UV-C LED technology within the cold water tank automatically activates hourly, inhibiting up to 99.99% of bacterial growth, ensuring every drop of cold water is clean and hygienic.

Hong Kong Standard Certified: Peace of Mind

This Philips direct-drinking water station is designed and manufactured in accordance with Hong Kong standards, fully complying with the latest Hong Kong standards (e.g., AS/NZS 3497:2021 Drinking Water Treatment Systems Standard), and is WaterMark certified. This certification ensures the product meets all regulations, safety, and performance requirements for household use in Hong Kong, giving you peace of mind.

Advanced Filtration & Smart Features

  • Aquaporin Inside™ RO Technology: Mimicking nature's power, this system uses a biomimetic membrane containing aquaporin proteins, effectively filtering extremely tiny substances. This technology has been tested in collaboration with NASA and the European Space Agency for space missions, proving its exceptional innovation and reliability.
  • FreshPro™ Anti-TDS Creep Technology: Through automatic pure water flushing, this technology reduces TDS creep even when the system is idle, ensuring every glass of water is consistently pure.
  • Mineral pH+ Alkaline Technology: Unique remineralization technology replenishes beneficial minerals and naturally raises the pH level, providing smoother and more refreshing alkaline water.
  • Tankless, Compact Design: Capable of providing up to 1000 gallons of pure water daily with a flow rate of up to 2.6 litres per minute, making it 20 times faster than traditional systems. The tankless design (featuring only a small integrated heating/cooling tank) saves under-sink space and offers improved hygiene and efficiency.

Smart Faucet: Effortless Control

The elegantly designed smart faucet, featuring a durable ABS plastic and zinc alloy casing, integrates system control and pure water output. A simple turn of the knob allows you to select 5 temperature levels and 4 dispense volumes (250ml, 350ml, 500ml, or 1000ml). Its 120° swivel design offers flexible convenience, and it comes equipped with a real-time TDS display, allowing you to monitor water quality with confidence.

Philips AUT9028DG/90 Under-Sink Hot & Cold RO Water System (Grey) Review

Ci*****u 15/07/2025

新屋裝修揀咗好耐,最後買呢部。裝完個kitchen即刻高級晒,水龍頭個design好靚。唔使再煲水同擺個熱水壺喺枱面,慳返好多位,冷熱水即㩒即有,好方便!

Mr. Cheung 10/01/2025

Product is good, water tastes clean. But the installation fee was a bit higher than I expected. BBE's sales team was helpful with my pre-purchase questions though. Overall, acceptable.

Mrs. Ng 22/11/2024

Bought this for the family. The RO filtration gives me peace of mind, especially for the kids. The 45°C water is perfect for my baby's formula. Delivery from BBE was super fast.

El*******k 28/05/2025

Perfect for a tea lover like me. The 85°C and 95°C settings are accurate and make a huge difference in taste. The slim design under the sink is a bonus. Well-packaged.
