I have the filter system installed under/on the kitchen sink. Consequently, the comparison between the water from the faucet and the filtered is easily made. The faucet water smells like chlorine, and on the rare occasions I taste it in a bathroom sink, the quality of the filtered water is readily apparent. And that's just the taste and smell. It's also filtering out the other toxins that are common in the municipal water supply. "Don't drink the water" now applies in the US. This is a great filtering system. Pay attention to your and your family's health. Drink filtered water!
