Overview
Sized about 3.46 by 3.46 by 5.43 inches, the WD-F41 is Waterdrop's NSF-certified replacement cartridge, sold as a single unit for compatible under-sink or countertop Waterdrop systems.
Its compact, roughly cube-shaped dimensions point to an inline or quick-change cartridge design rather than a large-capacity block, the kind Waterdrop uses across several of its smaller filtration systems.
