Water Ionizer PRIME 901S Undercounter

1) What makes the Water Ionizer PRIME 901S Undercounter different from the countertop model?
The Water Ionizer PRIME 901S Undercounter offers the same advanced technology and filtration performance as the countertop version but in a space-saving under-sink design. It comes with a digital touch faucet mounted on the worktop, allowing full control of pH levels and filter monitoring while keeping the main unit hidden. This design is ideal for modern, minimalist kitchens, providing premium performance without visible clutter.

2) What types of water can the Water Ionizer PRIME 901S Undercounter produce?
Just like the countertop version, the Water Ionizer PRIME 901S Undercounter produces 8 preset water types, all customisable via the faucet’s digital controls:

• Strong alkaline water – for cooking, washing produce, or cleaning residues

• Alkaline drinking water – for daily consumption (pH 8.5–9.5)

• Neutral purified water – ideal for baby formula or taking medication

• Weak acidic water – suitable for skincare and gentle cleaning

• Strong acidic water – for disinfecting surfaces

All pH levels can be easily adjusted using the digital control interface on the faucet, you don’t need to access the main unit.

3) How does the Prime Faucet work?
The Prime digital faucet is installed on the countertop and connects directly to the under-sink ionizer. It features touch-sensitive buttons and an illuminated display showing pH level, ORP, and filter life. You can instantly switch between water types and monitor system status in real time, making operation intuitive and elegant.

4) Does the undercounter unit filter water the same way as the countertop model?
Yes. The Water Ionizer PRIME 901S Undercounter uses the same dual internal filtration system as the countertop version. It combines multi-layer carbon filtration with advanced purification technology to remove chlorine, heavy metals, and sediments. Filter replacement is simple, the filters are accessible through the cabinet door and can be replaced without removing the unit.

5) How long does it take to produce alkaline water?
Production is instantaneous. Once you select the desired pH level from the Prime Faucet, the Water Ionizer PRIME 901S Undercounter produces alkaline or acidic water in real time, delivering it directly through the faucet outlet.

6) What is the ORP value of the water produced?
The Water Ionizer PRIME 901S Undercounter delivers the same high antioxidant capacity as the countertop model, producing water with a negative ORP of up to -800 mV (depending on your water source and settings). This antioxidant-rich water helps reduce oxidative stress and supports cellular protection.

7) Can it be installed in any kitchen?
Yes. The Water Ionizer PRIME 901S Undercounter fits easily under most standard kitchen sinks. It requires:

• a cold-water connection,
• a power outlet, and
• a 35 mm hole in the countertop for the faucet.

The installation kit includes all necessary fittings. For optimal results, installation should be done by a qualified plumber or technician, although the process itself is straightforward.

8) How often should I replace the internal filters?
This model also uses two internal filters: one lasting up to 3,000 litres, and the other around 5,000 litres. The digital faucet display tracks usage and alerts you when replacement is due, along with voice notifications. Actual filter lifespan depends on your household’s water quality and usage.

9) How do I clean or maintain the unit?
The Water Ionizer PRIME 901S Undercounter performs automatic self-cleaning after each use, just like the countertop version. It’s recommended to run a mild internal cleaning cycle every three months (or more often in hard-water areas). A cleaning kit is included, and detailed instructions are provided in the manual. Regular cleaning and timely filter changes preserve pH accuracy and antioxidant performance.

10) Who can drink alkaline water?
Alkaline water from the Water Ionizer PRIME 901S Undercounter is suitable for daily use by most people, including adults and children over three years old. It’s also safe for pets. For baby formula, always use neutral purified water. If you have a health condition or take medication, consult your doctor before adjusting your water intake.

11) Are there any side effects from drinking alkaline water?
Alkaline water is considered safe. Some first-time users may experience mild detox symptoms during the initial days, this is temporary and indicates that the body is adjusting to improved hydration. If you have medical conditions or take medication, always follow your doctor’s advice before changing your water habits.

12) How much alkaline water should I drink daily?
Most users benefit from about 2 litres per day, depending on lifestyle, activity level, and climate. Start gradually and adjust based on your comfort. People who exercise frequently or live in hot environments may require more. Always follow your doctor’s hydration recommendations if you have specific health concerns.

13) Is it safe to drink alkaline water every day?
Yes, it is safe for long-term, daily use. Start with a lower pH (around 8.0-8.5) and increase as your body adapts. Hydrogen-rich alkaline water helps maintain balance, energy, and hydration. Individuals with medical conditions should seek professional advice before making significant changes.

14) What warranty and after-sales service are provided?
The Water Ionizer PRIME 901S Undercounter includes a 5-year warranty covering parts and manufacturing defects. Technical support, filters, accessories, and replacement faucets are available directly from Alkaline Prime, ensuring long-term reliability and service.
