Ordering was quite easy since they have many many sizes and the ordering process was easily done. The seeming endless emails afterward were bit much though.

The filter fitted perfectly in our unit. Quality appears to be as advertised. I bought these because they are made in US.

Purchasing from Filterbuy is cost effective and great products. We change our filter monthly due to heavy pollen.
