Overview
Aquasana's AQ-CWM2-B relies on a carbon block cartridge, weighing about 6.2 pounds with a roughly 9.7 by 8 by 11.6 inch footprint sized for countertop placement rather than under-sink or whole-house installation.
Carbon block media is denser than loose granular carbon, which typically means slower flow but more contact time for taste and odor reduction. At under 10 inches on its longest side, this reads as a compact countertop unit rather than a large-capacity system.

Who it's for
