The Brita 1-Pack Stream Replacement Water Filters feature Filter-As-You-Pour technology. Now there’s no need for a traditional reservoir, so no more waiting at the sink for the water to filter. It also removes chlorine taste and odor, delivering great-tasting water without the waste. And it’s easy to set up. Run the new filter under cold water for 15 seconds and insert it into the filter cage until it clicks. You’ll only need to replace your filter ever 40 gallons or two months.
