Because the filter media is denser, your system will have to work harder to pull the air through a higher MERV rated filter. Higher MERV filters may not be appropriate for weak systems - very old ones, or ones which are too small for the house. Your bill may be higher due to the unit running longer, or you may not get the airflow and cooling you want.
Polyester and fiberglass throwaway filters are becoming less common as more and more organizations realize that low-MERV filters are inadequate for protecting people from harmful air contaminants which can cause or exacerbate health conditions. Many organizations now recommend a minimum of MERV 8 for homes, schools, and offices.
If you have a special situation where lower resistance or extra airflow is required, please contact us for more information.

The size printed on the filter is the size of the return opening it goes in. The filter itself needs to be slightly smaller than the return frame so that it will fit easily.
