Culligan US-EZ-3: Under-Sink Filtration With Culligan Brand Support
The Culligan US-EZ-3 is a 3-stage under-sink filter system installed on the cold water supply line under the kitchen sink and delivering filtered water through a dedicated chrome faucet that mounts at the sink deck. Three filtration stages: sediment pre-filter (5-micron), granular activated carbon (chlorine and taste), and carbon block post-filter (lead and particulates). NSF 42 and 53 certified. The 500-gallon filter capacity covers approximately 6 months of drinking water use for a family of four.
Culligan Brand Service Network
A key differentiator for Culligan products is the authorized dealer network -- over 800 U.S. dealers who offer in-home filter delivery, installation assistance, and water testing. Buyers who prefer not to self-maintain a filter system can arrange Culligan dealer service for filter replacement and system inspection. This dealer network is unavailable from online-direct competitors like iSpring and APEC.
