[This review was collected as part of a promotion.] Filterbuy makes a quality filter with a full suite of sizes that actual fit my needs. Dealing direct with the manufacturer made sense with their free and timely delivery service. Id highly recommend Filterbuy.

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.

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