As Advertised - Shipped poorly

As title suggests, the price and quality of these filters seems pretty good. They shipped without any added protection so the frames on my product were bent requiring me to reinforce one of them for use with a dowel. . . but otherwise the filter media seems to be good and they work well.

So happy to have the next 6 months covered at such a responsible price, and got the 11 merv for the same price I was paying for 2 months of 8merv, with another product. So happy with your product. They work so much better, and great for our house, we have many pets. Farm life. Single mom saving every dime she can.
