Many municipalities treat tap water with chlorine， which can leave an unpleasant chemical odor and taste. Treated water can also contain minerals and metals that affect the way your tap water tastes and smells. The Westbrass D400 Under Sink In-Line Filter System reduces chlorine and odor for delicious， clean tasting water. Adding a D400 Filter Unit ensures the water from your water dispenser faucet tastes and smells clean and refreshing. The quick connect cartridge housing with 3/8 in. insert fittings also make it fast and easy to replace cartridges when needed. For best filtration results filter cartridges (F400R) should be replaced every 3-months to 6-months or 528 Gallons (2000 l). The F400 Filter Unit includes 1 Filter Unit and 1 F440R Filter Cartridge.
