The filters are well made and will allow good airflow through my older AC system.

I love that the sizing is just a bit smaller so that you don't have to jam the filters in place. Also, the air quality is superb!

These are the best filters - definitely worth a little more - you get what you pay for and your health and home are worth it. :)
