🌊 Product Overview
The LiquaGen 2.5” x 20” Activated Alumina / GAC Filter Cartridge provides extended protection against harmful contaminants often present in well and municipal water. Using activated alumina media combined with granular activated carbon (GAC), it effectively reduces arsenic (As III & V) and fluoride, while also improving taste, odor, and clarity.
With its 2.5" x 20” slimline design, this cartridge offers greater capacity and fewer replacements compared to shorter filters. Compatible with all standard 2.5” x 20” housings, it’s ideal for reverse osmosis systems, under-sink installations, and slimline whole-house filtration.
