    • Great value replacement filters.
These are excellent replacement filters for the Culligan under sink system. Easy to replace, just remember to turn the water off!

    • Water tastes good
Been using this brand of filters for a few years now with good results. They fit well in my under sink unit and the water tastes good. Saves me a few dollars off the name brand. It's refreshing that they are made in USA.

The filter is not compatible with the Culligan undersink filter. As the picture shows the Culligan filter has a "box" on top that receives a pin from the housing. The Aquacrest filter does not and it will not work without it. Ordered well in advance of need and now I am stuck with two filters I cannot use! ‐‐‐-------------------------‐- Update It appears that the "box" on the top of the filter is not needed. Just make sure your filter holder is in the water off position, then align the water ingress / egress stubs to fit into their associated female receiver. Shove it in and rotate the filter. ... show more
