Great for the money

Great value for harder to find small 12” vent filters. They fit tight but got it in and it's a game changer on airflow with clean filters. 5 pack is great for the money and you can replace them for a few months before you need more.

Great Experience at Walmart

Walmart always has a large supply of furnace filters. I am always able to find exactly what I need. These filters met my expectations and satisfied my need. Additionally, they were priced competitively. Finally, delivery was great — they arrived quickly and in perfect condition.

I really love getting my filters

The convenience of getting my filters by subscription is great! I never have check the size and then remember to get them at the store then get them home without crushing them in the car. I was buying them several at a time but that took up a lot of space. I am very happy with the price, quality and convenience.
