Purification Process

Nature’s Gift from Maifan Spring, Kisumu

Nestled in the lush landscapes of Kisumu City, lies a pristine natural artesian spring — the heart and soul of Maifan Mineral Water.

For decades, this spring has been a silent giver of life, flowing deep beneath layers of volcanic bedrock and mineral-rich soils. The underground journey from Nandi Escarpment naturally filters and enriches the water with essential minerals like calcium, magnesium, and potassium, giving it that uniquely smooth, refreshing taste our customers love.

Unlike surface water sources that are exposed to pollution, the Maifan spring is protected underground — untouched, pure, and continuously replenished by rainfall and natural aquifers.

Our Philosophy: Bottled at the Source

At Maifan Mineral Water Limited, we believe the best water should stay as close to nature as possible.
That’s why we bottle directly at the source at Maifan Spring.

This ensures:

✦ Zero contamination during transportation
✦ Maximum freshness retention
✦ Consistent mineral balance and taste

The result: pure, natural water — bottled where it flows.

The Science of Purity: Our 6-Step Filtration & Purification Process

To guarantee safety and consistency, every drop of Maifan Water goes through a state-of-the-art purification system that meets both KEBS and WHO water quality standards.

Pre-Filtration:

Water is passed through a multi-layer sand and gravel filter that removes suspended solids, dirt, and sediments - the first line of defense against impurities..

Activated Carbon Filtration:

This stage uses high-grade coconut shell activated carbon filters to remove chlorine, organic matter, and unpleasant odors or tastes - enhancing the natural flavor profile of the water.

Ultrafiltration (UF):

Ultrafiltration membranes remove bacteria, protozoa, and fine particles while retaining beneficial minerals. This step refines the water to crystal clarity without altering its natural composition.

Reverse Osmosis (RO):

In this high-pressure stage, water passes through a semi-permeable membrane that eliminates dissolved salts, heavy metals, and microscopic contaminants. This ensures 99.9% purity and balanced mineral content..

UV Treatment:

Water is exposed to Ultraviolet (UV) light - a proven, chemical-free disinfection method that neutralizes microorganisms, ensuring the water remains microbiologically safe.

Oxidation & Ozonation:

Finally, the water is treated with ozone, a natural oxidizing agent, which provides final disinfection and helps maintain long-lasting freshness in every bottle - without the need for artificial preservatives.

Quality Control & Laboratory Testing

Every batch of Maifan Water is subjected to rigorous testing in our in-house laboratory to confirm:

✅ Neutral pH balance (6.8 – 7.5)
✅ Absence of harmful microbes
✅ Correct mineral composition
✅ Taste, clarity, and odor standards

We also conduct random quality audits through certified external labs to maintain transparency and accountability.

Naturally Mineralized Water

Maifan Water naturally contains trace minerals that contribute to both taste and wellness:

Mineral	Health Benefit
Calcium (Ca)	Strengthens bones and teeth
Magnesium (Mg)	Supports nerve and muscle function
Potassium (K)	Balances body hydration and blood pressure
Sodium (Na)	Helps maintain fluid balance
Bicarbonates (HCO₃⁻)	Promotes digestion and neutralizes acidity

These natural minerals, combined with our advanced purification, make Maifan Water both refreshing and health-supportive.

Our Bottling Technology

Once purified, the water flows directly through sealed stainless-steel pipelines into our automated bottling plant, where it is:

✦ Bottled using contact-free filling technology
✦ Sealed under hygienic, temperature-controlled conditions
✦ Inspected, labeled, and packed for delivery

Our bottles are made from food-grade, recyclable PET plastic, and every batch is traceable by production code for quality assurance.

Preserving the Source

We understand that our spring is a natural treasure. To preserve it for future generations, Maifan Mineral Water Limited has implemented:

✦ Catchment protection through tree planting and soil conservation
✦ Water extraction monitoring to maintain natural equilibrium
✦ Wastewater management systems to prevent any environmental pollution

Through these initiatives, we ensure that the spring remains as pure tomorrow as it is today.

Customer Assurance

We promise every Maifan Water customer:

“What flows from nature reaches you — untouched, pure, and full of life.”

Our team constantly invests in research, technology, and environmental care to make sure that when you open a bottle of Maifan, you’re tasting happiness in its purest form.
