Product review (1 stars): Terrible Filters!  Stay away!
Can't get the water clean.  I put one in when I first received them and I used gallons to just get it somewhat clear.  Seemed to be okay for a while then the cloudy water returned.  Something is wrong with these filters.  Now I know why they were cheaper. Now it's too late to return them so I'm just going to throw them out as I don't trust what I'm drinking is safe.
