Great product

I like this product because it is well constructed and, my opinion only, but, by using this filter brand..my electric bill is very low. I think it does its job efficiently and I definitely see the difference in my monthly bill. As I said..it is my opinion..but, since I am the one paying the electric bill..this is important to me.
