Activated carbon is fine in many of the branded survival products like the straw products and does purify water. The problem with the Brita Filters as was discussed in a previous thread, was that upon dissection they were found to contain a minimal amount of activated carbon - with the majority of the filter matrix consisting of tiny white plastic beads. They are more of a marketing scam than any real use. Steer clear! I suspect but can not confirm that the plastic beads help to break down and reduce the Chlorine present in municipal water to a level that is not easy to detect by taste.
Filtering and boiling does not remove heavy metals or some chemical contaminants. TL.
