The best filters for my aging house. They keep the air flowing throughout the house. (The thick which you can buy anywhere where filters are sold just don’t work very well in my house).

Kept it in for one month. It does NOT collapse upward (direction of airflow) at all. The picture is of both the old and new filters on a white background, the used one, on the left, to me was very slightly darker. There are two nonsmoking adults in the house with two cats. We live in an area that I consider low dust, pollen would be the biggest problem and I think this filter would be ineffective for pollen. The house is about 1600 square feet.

So far no problem with them, I change them out every month. These are perfect for the summer since they allow the maximum airflow to get through. I probably will change to different type one the summer is gone.
