One of the best filters for pet dander and all the pollen.

Great filters for a great price. Filtrete is the only brand that I buy.

Great filtration, good for you, your air and your system.

Purchased because of the cost which was lower than buying separately.

Great filters and great price

Love the four pack for the price.

Very good filters at a great price!

Wish you carried more sizes. I need 14X20 as well!

These do a great job. Great job keeping the dust down in the house!

Great ac filters ; can buy in quantity;
