Product review (1 stars): Black dome filter can't filter lime scale
I bought the propur system with the black dome filters for my home that has well water.  I had previously bought a system for another property and was happy with the pro water white filters. The black dome filters to my disappointment could not even filter out the lime in my water that I can see with my own eyes.  It's suppose to filter out bacteria and other things to a microbial level but can't filter lime.... Amazes me really.  Get the white filter not the black dome
