Clearbrook Water Filters are USA-made, high-efficiency gravity filtration systems designed to deliver purified drinking water without electricity. Compatible with most stainless steel gravity housings (including Berkey), Clearbrook filters use advanced carbon block technology to reduce fluoride, heavy metals, and contaminants while retaining beneficial minerals. Unlike standard filters, Clearbrook offers ANSI-tested reliability for your familyβs health.
