The Doulton SS2 Gravity Filter System is a portable stainless steel unit containing two W9121200 7-inch Super Sterasyl Ceramic Filter Candles, each with three stages of filtration. The cleanable, reusable candle cartridges feature a domed end and a plastic-mounted top with 0.25" threads. The filter candles reduce suspended solids, iron, lead and other trace contaminants, as well as improving taste. They will not remove beneficial and pleasant-tasting minerals from your drinking water.
