These  carbon air replacement filters are really what we need to help eliminate the pollutants in the air in our home.  We are home with five cats and we really noticed the difference this carbon filter makes when running our air purifier.  They are very easy to install and replace the old ones .  We’ve had so many hot days this spring and summer and have spent more time indoors with quarantine so we’ve been cooking a lot.   The Odor eliminating carbons have worked wonders.  Cat smells and cooking smells have gone away.
