Is there any health risk with using a charcoal filter in a brita water bottle daily? some online claim it causes digestive/intestinal problems?

I don't think so: We give oral activated charcoal to absorb drugs in overdoses, in those doses activated charcoal has been known to cause GI side affects. The charcoal in the filter should not leach into the water you are drinking in a significant amount to cause symptoms. Bacteria can grow in the filter and possibly cause GI symptoms. Make sure you change the filter at the recommended intervals.
