3M™ Aqua-Pure™ Whole House Large Dia. Replacement Filter Cartridge, Model AP917HD, 1 per case, 5621006

The scale inhibition feature in the AP904 Whole House Filtration System uses polyphosphates in minute quantities to bind calcium and magnesium hardness minerals, preventing them from becoming a solid and building up on metallic surfaces, which can reduce flow rates throughout the home's plumbing system. The stainless steel head assembly with 1” inlet and outlet connections helps provide high flow rates of up to 20 gallons per minute (gpm) / 75.7 liters per minute (lpm) to meet the needs of most residential applications. Our innovative Sanitary Quick Change (SQC) design allows for fast and easy cartridge change-outs without having to contact the filter media or the need for a filter wrench.
