We have used these filters for several years now. They work very well, con trol dust and pollen better than most. They are a good price and delivery is fast. Can't ask for more than that.

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.
