Sediment + PFAS Carbon Block Big Blue 20" Filter System

Whole House PFAS Filter, 20" Big Blue

This two-stage 20" Big Blue system filters all the water coming into your home. A 50/5 micron sediment cartridge comes first, then a 1 micron PFAS carbon block cartridge certified by IAPMO to NSF/ANSI 53 for PFOA and PFOS reduction.

What It Reduces

• PFOA and PFOS ("forever chemicals"): certified by IAPMO to NSF/ANSI 53
• Chlorine taste and odor
• Chloramine (not certified for chloramine reduction)
• Sand, rust, silt and fine particles down to 1 micron

How It Works

1. Stage 1, sediment (50/5 micron): catches sand, rust and silt so the carbon block lasts longer.
2. Stage 2, PFAS carbon block (1 micron): reduces PFOA and PFOS, chlorine taste and odor, and fine sediment. It also reduces chloramine (not certified for chloramine reduction).

How Long Do the Cartridges Last?

The PFAS cartridge is certified for 12,814 gallons. A 2 person home using about 150 gallons a day reaches that in about 12 weeks. PFAS has no taste or smell, so replace the PFAS cartridge on schedule rather than waiting for a change in the water. Change the sediment cartridge when water pressure drops.

Replacement cartridges: PFAS carbon block 4.5" x 20" (F1012930) and CWS dual grade 50/5 micron sediment cartridge (F1012400).

Installation

Install on the main water line where it enters the home, after the main shutoff and before the water heater and any water softener. Add shutoff valves and a bypass so you can change cartridges without shutting off the whole house.
