Just purchased this online from Bed, Bath, and Beyond. They had the best price after doing some research. It arrived very quickly. My handy husband installed it quickly and easily. We did a blind taste test of the water and it was quite obvious which was the filtered water. We always had a well as our water source and therefore always had a reverse osmosis system. We just moved to a new house and we are now on city water. We decided we didn’t need the RO system, just filtration and decided on this one based on reviews. We are very pleased and look forward to our nice clean, great tasting water!
