    Filter would perform better if it was actual size as stated. does it really make sense to cut the product down?

                    This is a good quality filter. Well made and efficient. I use it in the central air system in my business and my home. After trying other filters, this one does the job best and I will continue to purchase this same filter from this distributor, as needed.

                      I have new construction and the filter that the builder put in were just fiberglass and our house was full of dust. I replaced the fiberglass filters (that didn't even fit very well) with these pleated filters and I have noticed a marked decrease in the amount of dust. And they fit perfectly. Will definately purchase this filter again!
