Product review (1 stars): Basically useless
Beware, after talking to Bosch customer service I determined this filter basically only filters for cysts and aesthetic issues (sediment). It does NOT filter for lead or any other metallic or chemical contaminant. Why even bother filtering then? Bosch does not have alternate filters to replace this (they make one filter model per fridge). Also, we couldn't get the old filter out of our fridge despite the instructions to simply twist.
