Clean, safe drinking water is essential for every South African household. Whether you’re using municipal supply, borehole water, or harvested rainwater, a reliable filtration system makes a big difference. JoJo’s water filters are trusted across the country, but their cartridges don’t last forever. Knowing when and how to replace your JoJo water filter cartridge ensures your family continues to enjoy healthy, great-tasting water.
Why Replacing Your JoJo Filter Cartridge Matters
A fresh filter cartridge removes sediment, bacteria, and other contaminants effectively. Over time, though, cartridges clog up and lose efficiency. When left unchanged, not only does water quality decline, but bacteria can also build up inside the filter.
For homeowners, this means:
- Fresher, better-tasting water
- Consistent water pressure in the home
- Longer lifespan of appliances that rely on clean water

When to Replace Your JoJo Water Filter Cartridge
As a rule of thumb, countertop and undersink filters should be replaced every 6 months or after 3 000 litres, whichever comes first. Whole-house systems typically need new cartridges every 6–12 months, depending on usage and local water quality.
But lifespan varies:
- South African households consume an average of 237 litres per person per day (well above the global average of 173 litres). High usage means cartridges can clog faster.
- Borehole or rainwater may contain more sediment than municipal supply, shortening filter life.
Common signs it’s time to change your cartridge:
- Water tastes or smells different
- Reduced water flow or lower pressure in taps
- Visible discolouration inside the filter housing
