Bent on arrival
on September 11, 2025

This is the second time I've purchased these large filters online from 2 different companies. Both times the packaging has been crushed around the corners. The one's I received from Filter Buy can still be used after bending them back into shape. I just wish that they would reinforce the boxes, especially at the corners so the large filters could arrive undamaged. As for the quality of the filter, it looks to be good.
