Absolutely the best purchase you can make. After much research into water purification products I found the Pure Effect Filter System to have incredible quality of design, manufacture and customer service, in addition to great tasting pure water. I've never been able to drink tap water without being left with a metallic after taste and a sense that I was more thirsty than before. Kicking the bottled water habit became a priority after sensing a degradation in even the water that I was purchasing and finding that the plastic leeches into the water. I was concerned about the environmental impact of all that plastic. Through exploring this website I found a wealth of valuable information and a high level of customer service. I am over joyed with the products quality construction and ease of installation. The water that I now refrigerate in glass containers has a great taste and I'm confident that it is purified from toxins like fluoride, chlorine, heavy metals, pharmaceuticals and now radiation, that are even present in bottle water. Happily the Nestle corporation does NOT have my business now as I feel that drinking pure water IS a right that we should all have as human beings sharing this planet.
