This filter fit in my softener like a glove. Better price through Home Depot than from the manufacturer website from what I could find. Shipping time was very prompt. Overall, great purchase!

We use the system as a whole-house water softener. Works great. The original cartridge was rated for 6 months and lasted about 8, for a household of 2 adults. This is rated for 2 years.
