Too big. Had to be forced in. I take a 20x30x1 filter and bought a 20x30x1 but this seems to be .3 inches wider then it supposed to be. Would be a good buy it fit. Maybe a factory defect?

I had no problems with the older version/model of this filters. The filter mesh was different. This new version restricts airflow and will cause ac problems.

Have been using these filters for past 6 years. Very durable and helps with allergens. Price better than any other place that I can locate.
