Overview
Replacement water filter cartridges from Filterlogic, sold in a pack of three and certified to NSF standards 42 and 372, each measuring about 7.09 x 2.36 x 6.22 inches.
NSF 42 covers reduction of chlorine taste and odor, while NSF 372 confirms the filter is lead free in its construction. This is sold as a replacement cartridge rather than a full appliance, meant to swap into an existing filtered fridge or dispenser system rather than stand on its own. The listing does not specify which appliance models it fits, so buyers should confirm compatibility against their current filter's part number before ordering.
- NSF 42 and 372 certified
- Pack of 3 cartridges
- Compact 7.09 x 2.36 x 6.22 in size
- 0.62 lb per cartridge
Who it's for
Fits buyers who already own a filtered refrigerator or dispenser and need replacement cartridges rather than a new appliance. Not useful to anyone shopping for a standalone filtration system or dispenser.
