Whole-House CTO Chlorine Taste & Odor Removal - EXPRT 20 × 4.5 in. Big Blue carbon block cartridge reduces 99 % chlorine, reduces VOCs, pesticides, herbicides, foul taste & odor and industrial solvents, delivering clean, safe water at every tap.
Premium 100 % Coconut-Shell Carbon Block - Ultra-porous media traps sediment up to 10 micron while restoring clean taste and smell; safe food-grade construction meets drinking-water standards.
High-Flow / Long Life - Maintains 12 – 15 GPM at 80 psi with minimal pressure drop and treats 100 000 gal or 6-12 months before change-out*—ideal for large homes and light commercial use. (May vary depending on the quality of the feed water.)
Universal Point-Of-Entry Fit - Slides into any standard 4.5 × 20 in. “Big Blue” housing, making whole-house carbon filter replacement fast and tool-free on city or well-water systems.
Individually Wrapped & USA Support - Each cartridge arrives shrink-sealed for purity and is backed by lifetime U.S. tech support and EXPRT warranty. Note: does not reduce TDS—pair with an EXPRT Reverse Osmosis system for dissolved-solid removal.
