Product review (1 stars): Terrible product.  White particles floating in water.
Terrible.  Caused white particles to form in our water and we emptied close to 30 gallons of water and they were still there.  They weren't bubbles because they did eventually settle to the bottom of the cup.  We removed the filter and had to empty another 20 gallons to get it to run clear.  I returned this item and I would not buy it again.  Get the PUR one if you need one at all.
