Overview
The Waterdrop EWF01 is a replacement water filter built to fit the Equator OR400, NSF certified and sold as a 3-pack. Each cartridge measures 4.53 x 6.5 x 6.89 inches.
Sized notably larger and boxier than a typical fridge door cartridge, this filter's dimensions and stated Equator OR400 compatibility point to a specific dispenser or cooler fit rather than a standard door filter. Buying in a 3-pack covers multiple replacement cycles up front.
