Which filter fits your system?
Culligan with ZeroWater Technology
Our new Culligan with ZeroWater Technology filter offers superior filtration, but it’s not compatible with older ZeroWater pitchers and dispensers—so let’s make sure you get the perfect match!
You likely have the new technology if:
-
Drop-in filter
The filter drops in from the top of the upper reservoir.
-
Culligan logo
Your pitcher or dispenser will feature the Culligan logo.
-
Updated lid design
Your unit has a sliding lid for quick and easy refilling.
Legacy ZeroWater Technology
Legacy ZeroWater Technology filters were designed for earlier pitchers and dispensers. Newer systems use updated filtration technology, so the two filter types don’t mix and match.
You likely have legacy technology if:
-
Bottom-threaded installation
The filter screws into the bottom of the upper reservoir.
-
ZeroWater logo
Your pitcher or dispenser will feature the ZeroWater logo.
-
Removable lid
The entire lid must be removed to refill your pitcher or dispenser.
Culligan with MaxClear Technology
Gravity water filter systems compatible with MaxClear filters
While MaxClear gravity filters were engineered for universal compatibility, some systems may not support this filter design. Make sure our filters are compatible with your device.
MaxClear filters are likely compatible with your gravity system if:
-
7" gravity filter
Your gravity system can fit filters that are 7" tall.
-
Carbon or ceramic block
Your filter is made from ceramic or carbon block filtration media designed for gravity filtration systems.
-
Upright filter installation
Your filter sits upright in the upper container, allowing water to flow through into the lower chamber.
