Product review (4 stars): Samsung's filters have better flow rate than Home Depot HDX filters
It kills me to have to pay so much more for the branded filter but the reality is that the house brand filters that Home Depot offers have a substantially LOWER flow rate. These original Samsung filters have much better flow. That said, I'm not sure if it's because there's just less "going on" inside of it or if the Home Depot HDX filters are just lousy. There's no visible difference in the water between the two, but I wouldn't expect there to be anyway (and my city water is really good any way; truth is, if I could just plug some sort of bypass in the filter opening, I'd skip the filters entirely).
