Many tract homes were built with a single central air conditioning and heating return. In this case adding a higher filtration filter can dramatically impede the airflow as the filter surface loads between the times that it is changed by the consumer or the air-conditioning contractor. Surface loading is where the face of a filter loads with dust and as it does airflow across the filter drops creating even less air for the blower unit to move to other portions of the home even though the efficiency of the filter increases because of the increased surface area that the air has to pass through.

Since higher quality air filters, not air cleaners, reduced to varying degrees the amount of air flow through a heating and air-conditioning system it is imperative that you understand the impact of utilizing a higher efficiency filter such as a pleated filter, electrostatic filter, or even in some cases a bag filter before you go to a home improvement center purchase one and then added to your air-conditioning or heating system. Filters that are advertised as HEPA filters typically have a much higher impact on airflow than other types.
