Having very large iron deposits in the water. Over the years I've tried filters of different microns to get rid of stains and discolouration of the water. That 20 microns and the next 5 microns is just right. Yes, the water is filtered twice before entering the house. My wife and I couldn't be happier. Good filter, good price and finally good clean water.
