Access to clean drinking water remains a challenge in Ghana due to pollution, poor sanitation, and unreliable water infrastructure. Fortunately, several water filtration systems have proven effective in removing contaminants and providing safe drinking water. Below, we explore the best water purifiers currently available in Ghana, considering affordability, efficiency, and suitability for different settings.
1. Reverse Osmosis (RO) Filters
Best for: Urban homes, offices, and areas with heavy metal contamination (e.g., mining regions).
How It Works:
- Forces water through a semi-permeable membrane, removing bacteria, viruses, heavy metals (lead, arsenic, mercury), and dissolved salts.
- Often includes pre-filters (sediment & carbon) and UV sterilization for extra purification.
Top Brands in Ghana:
- PurePro RO Systems – Reliable for households and businesses.
- Kent Gold RO – Popular in Accra and Kumasi, with mineral retention technology.
- AquaSure RO – Affordable and effective for urban use.
✅ Pros:
✔ Removes up to 99% of contaminants, including chemicals from mining.
✔ Good for brackish water and salty taste removal (coastal areas).
❌ Cons:
✖ Wastes water (3-4 liters wasted per 1 liter purified).
✖ Requires electricity and maintenance (membrane replacement).
2. Ultraviolet (UV) Water Purifiers
Best for: Killing bacteria & viruses in municipal or borehole water.
How It Works:
- Uses UV-C light to destroy microorganisms (E. coli, cholera, typhoid) without chemicals.
- Often paired with carbon filters to improve taste.
Top Brands in Ghana:
- Livpure UV – Popular in urban homes.
- Eureka Forbes UV+UF – Combines UV with ultrafiltration.
✅ Pros:
✔ Instant purification – No waiting time.
✔ No chemicals added to water.
❌ Cons:
✖ Does not remove heavy metals or chemicals (needs pre-filtration).
✖ Requires electricity.
3. Ceramic Water Filters
Best for: Rural areas with no electricity (e.g., Northern Ghana).
How It Works:
- Water passes through porous ceramic candles that trap bacteria, parasites, and sediments.
- Often includes silver nanoparticles to kill germs.
Top Brands in Ghana:
- Potters for Peace Filters – Used by NGOs in villages.
- Doulton Ceramic Filters – Long-lasting and easy to clean.
✅ Pros:
✔ No electricity needed – Ideal for off-grid communities.
✔ Low cost (GHS 200–500) and long lifespan.
❌ Cons:
✖ Does not remove viruses or chemicals (only bacteria & sediments).
✖ Needs regular cleaning to prevent clogging.
4. BioSand Filters
Best for: Rural households and schools (low-cost, sustainable).
How It Works:
- A concrete or plastic container filled with sand, gravel, and a biofilm layer that traps pathogens.
- NGOs like Pure Home Water promote these in Northern Ghana.
✅ Pros:
✔ No electricity or replacement filters needed.
✔ Removes bacteria, parasites, and some heavy metals.
❌ Cons:
✖ Slow filtration (1-2 liters per hour).
✖ Does not remove viruses or dissolved chemicals.
5. Activated Carbon Filters (e.g., Brita-style Pitchers)
Best for: Improving taste & removing chlorine (urban tap water).
How It Works:
- Carbon blocks absorb chlorine, pesticides, and bad odors.
- Common in sachet water production and households.
Top Brands in Ghana:
- ZeroWater Pitchers – Removes dissolved solids.
- Doulton Carbon Filters – Used with ceramic filters.
✅ Pros:
✔ Affordable & easy to use.
✔ Improves taste of municipal water.
❌ Cons:
✖ Does not kill bacteria or remove heavy metals alone (best paired with UV or ceramic).
6. Solar Water Disinfection (SODIS)
Best for: Emergency use in remote areas.
How It Works:
- Clear PET bottles are left in sunlight for 6+ hours—UV rays kill bacteria.
- Promoted by UNICEF in Ghanaian rural communities.
✅ Pros:
✔ Free & no equipment needed.
❌ Cons:
✖ Does not remove chemicals or turbidity.
✖ Weather-dependent (needs strong sunlight).
Which Water Filter is Best for You?
| Situation | Recommended Filter |
|---|---|
| Urban home with tap water | Reverse Osmosis (RO) + UV |
| Rural area with no electricity | Ceramic or BioSand Filter |
| Mining area (heavy metals) | RO System |
| Emergency/Outdoor use | SODIS or Portable Carbon Filter |
Final Thoughts
The best water filter for Ghana depends on location, budget, and contamination type. Urban households benefit from RO systems, while rural areas need ceramic or biosand filters. NGOs and the government should invest in sustainable, low-cost solutions to ensure clean water for all.
