The 22 Cup Ready-Read 5-stage Water Filtration Pitcher is perfect for a busy household to ensure you and your family have easy access to filtered water. The premium 5-stage water filtration removes virtually all dissolved solids from your tap water more than any other leading brand. Taste the difference with refreshing and pure-tasting filtered water with each sip. Just twist the filter into the bottom of the reservoir and tighten it until there is a complete seal between the filter, o-ring, and reservoir. Fill the reservoir with cold tap water and place the lid on top.
