Do you know MERV?
MERV ratings (Minimum Efficiency Reporting Value) measure a filters ability to remove particulates from the air. They range on a scale from 1 to 16; the higher the rating, the more effective the filter is at collecting particulates.
As you can see, there are a number of inadequate filters out there. Thats where we come in. The air filtration experts at 72 Degrees can install an air filtration system in your home that is effective in picking up particulates that are less than one micron in size, thereby removing most common household particles (dust, for example).
