Does an excellent job of keeping the air clean and controls the dust. Its nominal size fits where other 4" filters won't. Excellent product.

It fits perfectly, unlike others in the same size, and it works very well. Living in a very heavy pollen area, these work very well. I change them out every three months during summer and once a month during heavy pollen times. I highly recommend them.
