• Major two-stage water filter, model ZDR104.
• Two housings in series — sediment first, then carbon.
• Removing grit before the carbon stage stops the carbon clogging early.
• That extends cartridge life against a single-stage unit.
• Two stages mean lower cost and a smaller footprint than three.
• Wall-mounted with standard cartridge housings for easy replacement.
• Suits point-of-use filtration under a kitchen sink.
• The three-stage ZDR104 adds a further polishing stage.
