I have cats and these filters have really made a difference in the amount of dander and dust in the air. So glad I found them.

Ordered filterbuy because I couldn't get the correct size in out town. Just made a second order and made a subscription. We have dogs and horses so you can imagine the dust. They do a fantastic job.
