Its nice to buy 4 at once. That is a years supply

These a great deal , liked the product , just we have a whole protection of the allergy

I like being able to buy in bulk.

Great Filter for furnace/AC

These filters help keep the allergies down

I'm on a low fixed budget, retired. I appreciate the price on this quality item.

Easy ordering and pickup.

Good filters. Only 4 stars since of the filters had a manufacturing flaw that rendered it unusable.

Perfect and got 4 for the price of 2

Excelente calidad a la medida exacta
