When my ducts are cleaned the ones coming from the furnace are cleaner then the ducts that send air from the house to the furnace.

People need to understand that your filter is not there to clean the air in your house, it’s there to protect the equipment. MERV 8 is the densest filter that should be used. Higher MERV (denser) filters just make your unit overwork. This product is very cost effective when purchased in a 12 pack. I like the fact that these filters are manufactured in Indiana as I like to support American-made products.

I haven't used the filter yet but the delivery was prompt, the product was affordable and I enjoy being able to order my whole years worth of filters at one time and having them on hand to change every month. This makes it much easier and I get a better price for buying in bulk.
