Why Does Your RO Water Smell Bad?
Reverse osmosis (RO) water systems are renowned for providing clean and crisp drinking water.
However, if an unpleasant smell is coming from your RO water, it’s time to investigate.
In this article, we’ll delve into the six potential reasons behind the mysterious smell and explore effective solutions to restore your water’s freshness.
6 Reasons Why Your RO Water Smells and Their Solutions
1. Chlorine/Chloramine

2. Sulphur (Hydrogen Sulphide)
The unmistakable “rotten egg” smell is a significant sign of hydrogen sulfide gas. This compound can infiltrate your water source due to decaying organic matter or geological processes. To combat this foul scent, consider adding an iron removal filter designed to eliminate hydrogen sulfide.
Carbon filters are also very effective at neutralizing this rotten egg smell.
3. Algae, Bacteria
In the secluded confines of your RO system, algae and bacteria can occasionally thrive, emitting a musty smell.
This issue is more common in households where the RO purifier is not regularly used. This results in microbial growth inside filters and the storage tank.
If the RO system is left unused for days, make sure you first empty all the water previously stored in the tank and discard all the water from the first cycle.
4. Clogged Filter
A clogged or dirty filter can compromise the effectiveness of your RO system, leading to an unpleasant smell. Routine filter replacement, as recommended by the manufacturer, ensures optimal performance. Regular maintenance not only eliminates unwanted smells but also extends the lifespan of your RO unit.
5. Unused Water in the Storage Tank
Water stagnation in the storage tank can foster microbial growth, resulting in an undesirable smell.
To avoid such a situation, never leave purified water stored in the storage tank for more than two days.
Regularly flushing your storage tank and cleaning it with a mild bleach solution will solve this problem, maintaining the freshness of the stored water.
6. New Filter or Membrane
Sometimes, a freshly installed filter or membrane can emit a peculiar smell initially. This is usually harmless and dissipates with use. Per the manufacturer’s guidelines, running the system for an extended period helps flush out any residual smell from new components.
You must also discard the first tank fill after any filter or membrane replacement.
Conclusion
Your RO water should be a source of refreshment, not smell awful.
By understanding and addressing the root causes of unpleasant smells, you can restore your RO system to its optimal condition.
Regular maintenance, timely filter replacements, and periodic cleaning are key practices in ensuring your water not only meets purity standards but also remains free from any unwelcome scents.
