What is Reverse Osmosis (RO)?

Answer: Reverse Osmosis (RO) is a water purification process that uses a semi-permeable membrane with pores around 0.0001 micron to filter out dissolved salts, heavy metals (lead, mercury, arsenic), bacteria, viruses, chlorine, and chemical contaminants. The result is water quality comparable to distilled water.

💧 How Philips RO Filtration Works · Philips RO

The Philips RO process flushes contaminants through 5 sequential stages:

  1. Pre-filtration / Traps sediment, rust, and large particles from tap water.
  2. Activated Carbon / Removes chlorine, odor, and organic compounds.
  3. RO Membrane / RO 0.0001 micron membrane blocks heavy metals, bacteria, viruses, and dissolved chemicals.
    0.0001
  4. Post-Carbon Polishing / Final polishing for taste improvement.
  5. UV-C LED Sterilization / UV-C Eliminates 99.9% of any remaining bacteria in the filtered tank.

Models using RO: ADD6901, ADD6902, ADD6910, ADD6911L, ADD6912, ADD6920, ADD6921, ADD6922.

What is AquaShield 5-in-1 Filtration? / AquaShield 5

Answer: AquaShield is Philips' proprietary 5-in-1 RO filter cartridge used in the ADD6910 and ADD6911L. It integrates pre-filtration, activated carbon, RO membrane, post-carbon, and remineralization into a single replaceable unit — eliminating the need to swap multiple filters.

🛡️ AquaShield Advantages · AquaShield

  • Removes 110 kinds of harmful substances including heavy metals, pesticides, and pharmaceuticals.
  • Lasts up to 12 months under normal household use.
  • Single-piece design — replace once per year, no multi-cartridge hassle.
  • Genuine replacement: Philips ADD550 cartridge (fits ADD6910 / ADD6911L / ADD6915).

What is Aquaporin Inside® Technology? / Aquaporin Inside®

Answer: Aquaporin Inside® is a bio-inspired filtration technology that embeds aquaporin proteins — the same proteins found in human cell membranes that transport water — into synthetic filtration membranes. Originally developed for NASA and the European Space Agency for water recycling in space, this technology allows only pure H₂O molecules to pass through, blocking nearly all impurities.

🧬 Why Aquaporin is Special · Aquaporin

Aquaporin proteins were discovered by Nobel Prize winner Peter Agre in 2003. They are nature's most efficient water-selective channels — found in every living cell. Philips integrates these proteins into a synthetic polymer membrane that mimics biological water transport.

Aquaporin

Key Benefits

  • NASA & ESA tested: Used in space-station water recycling.
  • Highly water-selective: Only pure water molecules pass; salts, bacteria, viruses, microplastics blocked.
  • Energy efficient: Requires lower operating pressure than conventional RO.
  • Found in: Philips ADD6901, ADD6921, ADD6922.

How Does UV-C LED Sterilization Work? / UV-C LED

Answer: UV-C LED at 265-285 nm wavelength emits ultraviolet light that damages bacterial and viral DNA, preventing reproduction. Philips integrates UV-C LED inside the filtered water tank to kill 99.9% of bacteria as a second line of defense after RO filtration.

☀️ Why UV-C LED Matters ·

Even after RO filtration, bacteria can grow in the filtered water tank during storage — especially in humid environments like Hong Kong. UV-C LED provides continuous in-tank sterilization without chemicals.

。

Models with UV-C LED: ADD6910, ADD6911L, ADD6922.

How Does Instant Heating Work?

Answer: Instant heating uses a high-power heating element (2,100–2,400W) that heats water on demand as it flows through a heating chamber — not by storing pre-heated water. Hot water reaches the desired temperature in approximately 3 seconds, eliminating energy waste from keep-warm modes and ensuring freshness.

🔥 Benefits vs Traditional Kettles

Aspect Traditional Kettle Philips Instant Heating
Wait time 3-5 min boil + cooling ~3 seconds
Energy waste Re-boiling + keep-warm Heat only on demand
Freshness Re-boiled water Always fresh
Temperature control Boil only (100°C) 4 preset temps (45/85/95°C + RT)

Models: ADD6901, ADD6910, ADD6911L (4 preset temperatures: room temp / 45°C / 85°C / boiling).

What is Strontium & Alkaline Mineralization?

Answer: Some Philips models add beneficial minerals back into RO water after filtration to balance pH and improve taste. The ADD6920 uses Rich Strontium technology (adding the trace mineral strontium for natural mineral-water taste), while the ADD6922 uses Alkaline Mineralization (raising pH to 7.5-8.5 for a smoother mouthfeel).

⚗️ Strontium

Strontium is a naturally occurring mineral found in spring water, contributing to that "mountain spring" taste. Philips' Rich Strontium technology re-introduces trace strontium into RO water for a more natural drinking experience.

💧 Alkaline

Alkaline mineralization raises water pH to 7.5-8.5 by adding calcium, magnesium, and bicarbonate minerals. This gives water a smoother mouthfeel and may help balance acidity from diet. The ADD6922 also includes real-time TDS (Total Dissolved Solids) display.

Frequently Asked Questions

Q1. Is RO water safe to drink long-term? Yes. RO water is safe for long-term consumption. Philips models with mineralization (ADD6920 strontium, ADD6922 alkaline) add back beneficial minerals to balance pH and improve taste. RO
Q2. What is the difference between RO and Aquaporin filtration? Traditional RO uses a synthetic polymer membrane that filters by size. Aquaporin Inside® uses biological proteins embedded in a synthetic membrane that selectively transport only water molecules — offering higher selectivity and lower energy use.
Q3. Does UV-LED replace RO filtration? No. UV-C LED is a secondary disinfection, not primary filtration. It kills bacteria in the storage tank but does not remove dissolved chemicals or heavy metals — those require RO. ,
Q4. How much electricity does instant heating use? Instant heating only consumes power during dispensing (3-5 seconds at 2,100-2,400W). Overall, it uses less energy than a traditional kettle that keeps water warm, since there's no continuous keep-warm load.
Q5. What does TDS mean and why does the ADD6922 display it? TDS (Total Dissolved Solids) measures the concentration of dissolved minerals and contaminants in water, in parts per million (ppm). Lower TDS = purer water. The ADD6922 displays TDS in real-time so you can verify filtration performance and know when to replace the filter. TDS(
