Aquaboon 4.5 x 20 Carbon Block Filter Cartridge, 5 Micron – 1 Pack, Whole House Replacement (FC25B/CB-BB-20 Compatible)

Purify every drop in your home with Aquaboon

Meet the Aquaboon 4.5 x 20 carbon block filter cartridge, a 5-micron solution designed for whole-house filtration. Sized for standard 20-inch housings, it sits between your water source and every faucet, delivering clearer water for drinking, cooking, and bathing. The cartridge uses coconut-shell activated carbon to target common impurities, helping minimize chlorine smell and odors while preserving essential minerals where possible.

Key benefits arise from the media blend and rugged design. The 4.5 x 20 format fits many standard housings, and the 5-micron rating targets finer particles without noticeably restricting flow. The result is water that looks and feels cleaner, with less noticeable taste and odor, supporting everyday tasks with confidence.
