1) What makes the Water Ionizer PRIME 901S Countertop different from other models?
The Water Ionizer PRIME 901S Countertop is a premium household water ionizer featuring 9 platinum-coated titanium plates for superior efficiency and hydrogen production. It offers precise pH control, a modern digital touch panel, and advanced self-cleaning functions for consistent performance and long lifespan. It delivers one of the best value-for-money ratios in its category, combining premium build quality with advanced technology at an accessible price.
2) What types of water can the Water Ionizer PRIME 901S Countertop produce?
The Water Ionizer PRIME 901S Countertop offers 8 preset water levels, each with adjustable pH values. These include:
- Strong alkaline water – ideal for cooking, cleaning produce, or removing residues
- Alkaline drinking water – for daily hydration (pH 8.5–9.5)
- Neutral purified water – suitable for baby formula or taking medication
- Weak acidic water – perfect for skincare and gentle cleaning
- Strong acidic water – used for surface disinfection
All pH levels can be easily adjusted on the control panel, making the Water Ionizer PRIME 901S Countertop a versatile water system for the entire household.
3) How long does it take to produce alkaline water?
Production is instant. Once connected to your tap, the Water Ionizer PRIME 901S Countertop produces alkaline or acidic water in real time — no waiting or storing required.
4) Does the Water Ionizer PRIME 901S Countertop also filter contaminants?
Yes. It includes a multi-stage internal filtration system that removes chlorine, sediments, heavy metals, and odours. In areas with hard or heavily contaminated water, we recommend adding a pre-filter for additional protection and to extend the ionizer’s lifespan.
5) What is the ORP value of the water produced?
The Water Ionizer PRIME 901S Countertop can generate water with a negative ORP of up to –800 mV, depending on your water source and pH settings. This negative ORP gives the water strong antioxidant properties, helping to neutralise free radicals and support overall wellbeing.
6) Do I need a plumber to install the Water Ionizer PRIME 901S Countertop?
Usually not. The ionizer comes with all necessary accessories for a quick DIY countertop installation. It connects easily to your tap using the included diverter, allowing you to switch between ionised and regular water.
Alternatively, it can also be connected directly to the water line under the sink, this setup may require basic plumbing. Both installation kits are included for your convenience.
7) Can the Water Ionizer PRIME 901S Countertop be wall-mounted or hidden under the sink?
Yes. The Water Ionizer PRIME 901S Countertop can be mounted on a wall near the sink to save space and make the diverter easy to use. For an under-sink setup, you can add the Prime Faucet, which offers digital touch controls and real-time display directly on the worktop. This allows you to use the ionizer while keeping the main unit hidden.
8) How often should I replace the internal filters?
The Water Ionizer PRIME 901S Countertop uses two filters: one with a lifespan of about 3,000 litres and another of around 5,000 litres. The display continuously tracks filter usage and provides voice alerts when it’s time for replacement. Actual lifespan varies depending on your water quality and household consumption.
9) How do I clean or maintain the Water Ionizer PRIME 901S Countertop?
The Water Ionizer PRIME 901S Countertop includes a fully automatic self-cleaning system that activates after each use. For optimal performance, run a mild cleaning cycle every three months or more frequently in hard-water areas. A cleaning kit is included for convenience, and detailed maintenance instructions are provided in the manual.
10) Who can drink alkaline water?
Alkaline water from the Water Ionizer PRIME 901S Countertop is suitable for everyday use by most people, including adults and children over three years old. It’s also safe for pets. For infants and baby formula, always use neutral purified water. If you have health conditions or are under medical treatment, consult your doctor before changing your water intake.
11) Are there any side effects from drinking alkaline water?
Alkaline water is safe and well tolerated. Some new users may experience mild detox effects such as temporary fatigue or changes in digestion, these typically subside as the body adjusts to improved hydration. If you have chronic health issues or are on medication, seek your doctor’s advice before making major changes.
12) How much alkaline water should I drink per day?
Most people benefit from drinking about 2 litres per day, depending on body size, lifestyle, and activity level. If you’re new to alkaline water, start gradually and increase over time. Those with higher physical activity or warm climates may require more. Always follow your doctor’s hydration recommendations if you have specific needs.
13) Is it safe to drink alkaline water every day?
Yes. The Water Ionizer PRIME 901S Countertop is designed for daily and long-term use. Start with a pH of around 8.0–8.5 and increase gradually as your body adapts. Hydrogen-rich alkaline water supports hydration, energy, and balance. Individuals with medical conditions should consult a healthcare professional before changing water habits.
14) What warranty and after-sales service are provided?
The Water Ionizer PRIME 901S Countertop is covered by a 5-year warranty for parts and manufacturing defects. Support, replacement filters, and accessories are available directly from Alkaline Prime, ensuring long-term reliability and service.

Best alkaline water filter.
I recently purchased an alkaline water filter and I couldn’t be happier with my experience. The filter itself is well-designed, easy to install, and works efficiently. I’ve noticed a positive difference in hydration and overall well-being since making the switch. Customer service was also outstanding, providing helpful advice and fast delivery.
If you’re looking for a reliable alkaline water filter, I highly recommend Alkaline Prime.
