Water Filter For Tap

We normally drink bottled water at home. We use filtered tap water for our hot water. I was just wondering if tap watered filtered by Brita charcoal is safe to drink. My wife says activated charcoal does not filter out organisms or the tiny amout of parasites that might be in the municipal tap water.

I checked the label for the bottled water in the grocery store. They usually say it’s been ozonated and filtered by activated charcoal. Even the water from the spring water says it’s been filtered. That seems to tell me you need to filter out the organic impurities with charcoal and treat it with something to kill off the germs. Is that correct? Thanks.
