Under Sink Water Filters

Under Sink Water Filters

Why choose a Under Sink Water Filter?

Under sink systems remove contaminants from water like a reverse osmosis (RO) systems but leave in minerals like calcium and fluoride. Under sink filters are easier to maintain, have a higher flow rate & water pressure than RO systems, and unlike reverse osmosis systems, they produce no waste water.
