Do bacteria grow in Brita filters?

Author: scraper  |  Last update: Sunday, August 30, 2026

Yes, bacteria and mold can grow in Brita filters. Because the filters remove chlorine (which usually keeps water sanitary) and provide a moist environment with trapped organic material, bacteria can multiply quickly. In some cases, stagnant filters can harbor higher bacterial counts than unfiltered tap water.

Why stop using Brita filters?

People stop using Brita filters primarily because they primarily only improve taste and odor by removing chlorine. They do not purify water, often leaving behind heavy metals, fluoride, pesticides, and bacteria. Furthermore, if filters aren't replaced every two months, they can become breeding grounds for mold and bacteria.
