Floplus Protect 20BB Filter Cartridge

The Pentair FloPlus Protect 20BB Filter Cartridge makes defending your home's water easy and affordable. When used with the FloPlus Protect 20BB system, this cartridge is certified by IAPMO to reduce a wide array of contaminants, including up to 98% of PFOA and PFOS, the compounds commonly known as "forever chemicals." It is a high-capacity whole-house solution designed to deliver cleaner, better-tasting water throughout the home.

Fibredyne Filtration Technology

This cartridge features Pentair's proprietary Fibredyne filtration media for chlorine reduction, delivering great-tasting water straight from the tap. Its extremely fine 0.5-micron rating allows it to capture a broad range of contaminants down to a very small particle size, while the engineered Fibredyne structure is designed to maintain a high flow rate with low pressure drop. That combination is important in a whole-house application, because it means strong contaminant reduction without sacrificing the water pressure your household fixtures and appliances depend on.

• Up to 98% PFOA/PFOS ("forever chemicals") reduction when used with the FloPlus Protect 20BB system
• 0.5-micron rating for extremely fine filtration of a wide range of contaminants
• Fibredyne technology for chlorine reduction and great-tasting water
• High flow rate with low pressure drop
• 15,000-gallon (56,781-liter) capacity at a 5 gpm (18.9 Lpm) flow rate

The 20BB Big Blue format is a standard high-capacity housing size, making this cartridge a strong fit for higher-demand households that need both robust flow and meaningful contaminant reduction at the point of entry. With a rated capacity of 15,000 gallons at 5 gpm, it is designed to provide many months of service between changes under typical residential use, though actual life depends on your water quality and usage. To maintain the certified performance, replace the cartridge once it reaches its rated capacity rather than waiting for a noticeable drop in flow, and always install it in a compatible FloPlus Protect 20BB housing so the certified reduction claims apply. This cartridge is also referenced under the alternate part number 655223-43. For households concerned about PFAS and looking for a straightforward, high-capacity way to improve their water at the point of entry, this cartridge offers certified, broad-spectrum protection paired with the great taste that comes from effective chlorine reduction.
