Product review (3 stars): which is a hazardous waste product sold to water companies and advertised to help ...
My TAP water has 150 ppm suspended solids, and after the water passes through this filter it measures 135 ppm, very little improvement, more of a pacifier.  It does not filter out fluoride, which is a hazardous waste product sold to water companies and advertised to help your teeth - you need a reverse osmosis filter to get FLUORIDE out.  Read the Toothpaste labels.  Anyway, it does improve the water some.
