I had a Culligan RO system and tried to find replacement filters that were so expensive. For years I had to keep paying a Culligan service tech come out and replace my filters for an astronomical price. Then I found this conversion kit trough ESP. Ordered it and received two days later. It took my one hour to install. The kit cost less then Culligans replacement filters. I will subscribe for the replacement filters at less than half the price. Thank you for this solution to my problem.

I consistently have an excellent experience buying my filters from this company. I Get exactly what I need for my system, and they send me reminders with the item numbers attached. Once I order they consistently ship promptly and keep me updated on the tracking of the items. They are my go to now for replacing R/O filter cartridges.
