In terms of bacteria, however, Brita water filters do not aid to kill the microorganisms. If you have not changed your filter in six months, the Brita filter becomes useless.
Brita traps, but does not kill bacteria. Because the filter cannot kill bacteria, it actually becomes a breeding ground for the microorganisms if not changed regularly. An old, unchanged Brita filter can be dangerous because its use may add bacteria, which had been killed in the tap by chlorine, back into water.

Activated carbon filter media is relatively common, and is found in Brita or PUR filters.
AC [activated carbon] filtration should only be used on water that has been tested and found
to be bacteria free or effectively treated for pathogenic bacteria.
Statements similar to this one were found from numerous sources, leading to the conclusion that
activated carbon is simply unacceptable at removing bacteriological and viral contaminants.
