Yeah, good luck with that. Not what a Brita filter is for. All it does is take chlorine taste out of tap water. From the user guide of a Brita filter:

"The Brita Bottle is not intended to purify water. DO NOT USE WITH WATER THAT IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWN QUALITY WITHOUT ADEQUATE DISINFECTION BEFORE OR AFTER THE SYSTEM."

Or in other words, just drink the water, don't bother carrying the useless extra weight of the Brita.
