Seems like a great product and business model. I ditched my Brita filter for bottled water a couple years ago because of the black dots. It was embarrassing to pour water for people when there were black dots floating in it. Might have to switch back to a filter now.
the black dots are just activated carbon (the filter) that escapes after the filter starts to break down. What is wrong with your tap water that you feel you can't drink it? I only filter mine because the water near me comes out with a pretty gross taste.
