We bought these because we have a lot of dust in our house. Our house backs up to the woods. I read somewhere that the furnace was responsible for the dust so I decided to try these filters. What a difference!!! We have a lot less dust now and my allergies are better. This is the only filter I will use from now on. :blush::blush:
I can't rate them yet as we are still using the one we had before. We be happy to rate them later on. They look great and the size is right so they are probably terrific
