I really like these air filters. They really help especially during inversions, chimney smoke from neighbors fireplaces. I recommend them.

All is can tell you about the filter is it fit my a/c unit. I did not install it immediately. It was about a week. I think Iwould need to use it a month or so to determine how good it works. You have any questions.
