Why Does RO Water Taste Flat or Bitter? 5 Steps to Improve Water Taste
Restore natural sweetness and essential minerals to your drinking water using copper cartridges, alkaline balls, and precision TDS controllers.
Why Does RO Water Sometimes Taste Strange?
When an RO membrane removes all dissolved minerals without remineralization, the pH drops slightly into acidic territory (around 6.0-6.5), causing a flat or sour taste. Conversely, an expired carbon filter causes a bitter aftertaste.
5 Practical Ways to Enhance Taste
1) Install an Active Bio-Alkaline Cartridge to elevate pH to 7.5-8.5. 2) Add a Copper-Zinc infusion filter. 3) Calibrate the post-RO TDS controller to 100-120 PPM. 4) Replace coconut shell activated carbon. 5) Sanitize the storage tank thoroughly.
Key Takeaways & Recommendations
- Alkaline filters restore natural sweetness by adding calcium and magnesium.
- Copper infusion infuses antioxidant properties into drinking water.
- Regular tank cleaning prevents stale taste.
