I've been using this system for 10 years now. I've already said my tap water is terrible. In fact, it shows over 520ppm. With these filters and a reverse osmosis filter, the quality is 21 ppm. It's just as good as bottled water. I also use the Zero Water System and the quality drops to zero parts per million. The filter lasts me six to twelve months, depending on how much coffee and tea we drink. Unsurpassed quality and easy replacement. I love value too.
