## Customer Reviews

### ⭐⭐⭐⭐ Be aware of what you get when you purchase this.
*by G***N on December 25, 2022*

Appears to be quality product, however, it DOES NOT come with a wall bracket. By the time I purchase a wall bracket and screws to attach the bracket to the wall, I have not saved anything. It was aggravating to be prepared to install this filter housing only to find out that it did not come with a bracket. The website should have mentioned that.
