Factory made post-filter. Better than original, purchased 4/20/2019. Perfect fit in my Honeywell air cleaner F300E 20x25. 2 required (12.5 x 20), 2 shipped in pkg. Good for another few years !

Easy and convenient to order online. Since the filter are hard to find at the big box hardware stores I am glad to know I can get them from your website.
