Why is Your Filtered Water Cloudy?

Thursday, April 11, 2013 - by Water2Drink

Many people using a high quality point-of-use drinking water filter, such as a Multipure Drinking Water System, are surprised to sometimes see the filtered water looks cloudy. But why is that, if the filter system is so good at removing contaminants?

Certain times of the year, but especially when the ground and source water is cold, water flowing from the filter may be almost milky white. It's an interesting fact that one of the many properties of water is its ability to dissolve gases, including air. Colder water is denser than warm water and capable of holding more dissolved gases.

Quoting a Water Quality Report from the City of Santa Rosa, CA: "Sometimes the air comes back out of the water in the form of many tiny bubbles, giving the water a temporary milky white appearance. To determine if the white color in the water is due to air, fill a clear glass with water and set it on the counter. Observe the glass of water for two to three minutes. If the white color is due to air, the water will begin to clear at the bottom of the glass first and then gradually clear all the way to the top. This is a natural phenomenon and is completely normal; the water is safe to use."
