One of the things that you should check is MERV ratings. It is important that you choose air filter with higher rating preferably from 5 to 14. The benefit of higher rating is that it has higher efficiency in removing dust and other contaminants. The MERV always rate air filters according to their ability to remove dust and other contaminants. Being that the ratings always start from 1 to 20 you will not expect the filter that is rated 1 to work better than the one that is rated 20 which cannot be in real sense. One thing for sure is that tough stains can only be removed by air filters with higher ratings. Go to the reference of this site for more information about air filters excellairfilters.com
