I was very pleased with my purchase of the filterbuy A/c filter. Delivery was quick and the product was in perfect condition. I will buy again from Walmart.

Great Value

This is a great air filter! We have had to replace our filters a few times due to being in a new build along with other new homes being built around us. This is such a unique size, and thankful we had fast delivery and it's a great value!
