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.

Received order with no problems. Everything was good, however I have about 2 years worth of filters. I only use 2 filters a years. That why I have stopped my automatic order. When I use these filters up, I'll let you know. For now I don't need any filters. Thanks
