Review on Filterbuy 20X25X2 Air Filter MERV 8 Dust Defense (4-Pack), Pleated HVAC AC Furnace Air Filters Replacement (Actual Size: 19.50 X 24.50 X 1.75 Inches) by Michael Swanson

Quality seems as good as most. Most filters look alike. I went with the Merv 8 rated filter to better maximize airflow. The Merv 11 -13 rated filters sounded good but in real life scenario, they are only sucking air in through your intake vent which draws air from a limited area, therefore, not filtering the air in your entire home. With higher ratings, the airflow through the filter gets reduced, especially after it starts to get dirty. Reduced airflow can harm your equipment that relies on more air to stay cool during operation. For the money, these appear to be good filters. When you spend less, you are more apt to change the filters more frequently.
