Poor Fitment

Less pleats compared to other brands and is undersized compared to others. Will not purchase again.

The 11 was not recommended for my unit so I exchanged them. I took them to UPS and have not heard back from Filterbuy. Waiting

I dont like the green edges bc they show through my vents. Wish the edges were white like the actual filter.

I just replaced my old filters and they seem like decent quality- only time will tell how after they are BUT I dont like the green edges bc you can see it through the vents. My vents are white to I wish the edges were white!

Good value but could be more substantially made

The filter works well, however the opening on my vent is a snug fit which causes the filter to get bent. I think the thick cardboard frame makes the filter a bit larger than other filters
