Works but I think everything is over priced
John N✓ Verified Purchase•July 22, 2023
I chose this after reading reviews and comparing it to less expensive brands. I have no complaints but they're not cheap.
Good Fit

Works great , I've been using them for years.
Perfect fit replacement
Arthur J BEGIN✓ Verified Purchase•May 29, 2023
Perfect fit replacement filter cartridge. Were on a well and have so much water pressure now you have to turn it down. Awesome product. A little pricey but very worth it.
Best alternative
Young Chang✓ Verified Purchase•May 10, 2023
It cost the half buying from the Culligan dealer. It's also easy to install by yourself, saving the installation charges.
