🔹 What is a Mineral Cartridge?
A mineral cartridge, also known as a post-carbon or mineralizer filter, is a component added to a Reverse Osmosis (RO) water purification system. After water has gone through several stages of filtration — where it’s stripped of contaminants and unfortunately, some beneficial minerals too — the mineral cartridge restores essential minerals like calcium, magnesium, and potassium.
🔹 Why Mineral Cartridges are Important in Kenya
Kenya’s tap water and borehole water, while treated, often lack necessary mineral balance. RO systems, while effective at purification, also remove these nutrients. That’s where a mineral cartridge steps in. It helps:
Improve water taste
Restore healthy pH
Boost mineral intake
Support bone and immune health
🔹 Types of Mineral Cartridges in Kenya
1. Alkaline Mineral Cartridges
These add alkaline minerals and raise the pH level of your water, making it less acidic.
2. Bio-Ceramic Cartridges
These help improve the taste of water and also contribute to energizing it using far-infrared rays.
3. Calcium-Enriching Cartridges
Focused mainly on calcium restoration — crucial for kids, pregnant women, and the elderly.
