Why Chlorine Is in the Water

Chlorine is added to municipal water as a disinfectant. Without it, bacteria could grow in the miles of pipe between the treatment plant and your home. It's there for a good reason — public safety. But that doesn't mean you have to taste it at every glass.

Why the Taste Varies

Chlorine levels can fluctuate based on the season, the water source, and how far your home is from the treatment point. Some days you'll notice it more than others. If your home is closer to the disinfection point or the city is flushing lines, the taste can be stronger.

How to Reduce It

Carbon filtration is the standard approach for chlorine taste and odor. A whole house carbon filter reduces it at every tap — showers included. For drinking water specifically, reverse osmosis also reduces chlorine along with a broader range of contaminants.
