## Customer Reviews

### ⭐⭐⭐⭐⭐ Water filter
*by D***S on June 21, 2026*

Works great and installation went smoothly. Got a better price than other sites. It came with what was needed even. Highly recommend this.

### ⭐⭐⭐⭐⭐ Order to replace.
*by K***R on April 26, 2026*

Bought to replace a 15 year old filter that was leaking. Takes a few minutes to install. Make sure the gasket is in place or it will leak. The clear tank makes it easier to see if the filter needs to be replaced earlier

### ⭐⭐⭐⭐⭐ Filter Plus Add-ons Make This a Good Value
*by P***N on July 24, 2026*

I've used 3 variations of Omni Whole house filters over the last 30 years. This is like the 1st filter I used (90s version) with threads on the outside of the base, which I prefer. Have been happy through the years and this package is a good value. Everything you need for install between the male 3/4" threaded connectors that you'll purchase separately. The initial price shows a bit higher, but the bracket and filter cartridge aren't included in many of the search returned products.
