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 micronto 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 Filtration Principle
The Philips RO process flushes contaminants through 5 sequential stages:
- Pre-filtrationTraps sediment, rust, and large particles from tap water.
It filters out sediment, rust, and large particles from the water. - Activated Carbon Removes chlorine, odor, and organic compounds.
Removes residual chlorine, odors, and organic compounds. - RO Membrane / RO:0.0001 micron membrane blocks heavy metals, bacteria, viruses, and dissolved chemicals.
A 0.0001-micron semi-permeable membrane blocks heavy metals, bacteria, viruses, and chemical pollutants. - Post-Carbon Polishing Final polishing for taste improvement.
Final taste adjustments. - UV-C LED Sterilization / UV-C Sterilization:Eliminates 99.9% of any remaining bacteria in the filtered tank.
Eliminate any remaining bacteria in the water tank.
Models using RO:ADD6901, ADD6902, ADD6910, ADD6911L, ADD6912, ADD6920, ADD6921, ADD6922.

What is Aquaporin Inside® Technology? / Aquaporin Inside® biomimetic water channel technology
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 forNASA and the European Space Agencyfor water recycling in space, this technology allows onlypure H₂O molecules to pass through, blocking nearly all impurities.
🧬Why Aquaporin is Special
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 proteins were discovered by 2003 Nobel Prize in Chemistry winner Peter Agre and are the most efficient water molecule filtration channels in nature. Philips has embedded them in synthetic polymer membranes to simulate biological water transport mechanisms.Key Benefits

How Does UV-C LED Sterilization Work? / UV-C LED Sterilization Principle
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 tokill 99.9% of bacteria as a second line of defense after RO filtration.
☀️Why UV-C LED Matters: Why are UV-C LEDs Needed?
Even after RO filtration, bacteria can grow in the filtered water tank during storage — especially in humid environments like Hong Kong. UV-C LED providescontinuous in-tank sterilization without chemicals.
Even with RO filtration, bacteria can still grow in the water tank in humid environments (such as Hong Kong). UV-C LED provides...No chemical sterilization is continuously applied inside the water tank.。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 inapproximately 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? / Strontium Mineralization and Alkaline Mineralization Technology
Answer: Some Philips models add beneficial minerals back into RO waterafter filtration to balance pH and improve taste. TheADD6920 uses Rich Strontium technology(adding the trace mineral strontium for natural mineral-water taste), while theADD6922 uses Alkaline Mineralization(raising pH to 7.5-8.5 for a smoother mouthfeel).
⚗️Strontium mineralization (ADD6920)
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.
Strontium is a trace element naturally found in spring water, giving it a pure "spring" taste. Philips' strontium mineralization technology adds trace strontium to RO purified water, restoring the natural drinking experience.💧Alkaline mineralization (ADD6922)
Alkaline mineralization raises water pH to 7.5-8.5by adding calcium, magnesium, and bicarbonate minerals. This gives water a smoother mouthfeel and may help balance acidity from diet. The ADD6922 also includesreal-time TDS (Total Dissolved Solids) display.
Alkaline mineralization raises the water pH to 7.5-8.5, adding calcium, magnesium, and bicarbonate to make the taste smoother and help balance dietary acidity and alkalinity. ADD6922 is also equipped withReal-time TDS water quality display。Technology Coverage by Model / Technical Comparison of Each Model

Frequently Asked Questions / Common Technical Issues
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 water is safe for long-term consumption. Both ADD6920 and ADD6922 incorporate mineralization technology to balance pH and improve taste.
Q2. What is the difference between RO and Aquaporin filtration? Traditional ROuses a synthetic polymer membrane that filters by size.Aquaporin Inside®uses biological proteins embedded in a synthetic membrane that selectively transport only water molecules — offeringhigher selectivity and lower energy use. Traditional RO filters based on pore size; Aquaporin Inside® embeds biological proteins into synthetic membranes, allowing only water molecules to pass through, offering higher selectivity and lower energy consumption.
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.No. UV-C LED is...Assisted sterilizationIt cannot remove chemical pollutants or heavy metals and needs to be used in conjunction with 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. Instant heating only consumes electricity during the water dispensing process (2,100-2,400W, 3-5 seconds), making it more energy-efficient than traditional insulated water boilers.
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 (Total Dissolved Solids) measures the concentration of dissolved substances in water in ppm. A lower value indicates purer water. The ADD6922 displays TDS in real-time, making it convenient to monitor filtration performance and determine when to replace the filter cartridge.
