See the for related codes and standards requirements, and criteria to meet national programs such as DOE’s Zero Energy Ready Home program, ENERGY STAR Certified Homes, and Indoor airPLUS. Air filters are an important component of forced air HVAC systems. Filters are installed on the return side of the HVAC air handler to clean the air to protect the HVAC motor and to improve indoor air quality. Filters should also be installed in fresh air intakes to clean outside air that is brought into the home. Filters with higher MERV (Minimum Efficiency Reporting Value) ratings of MERV 6 or above can trap pollutants like pollen, dust mites, and mold spores. However, a dirty, clogged filter can dramatically reduce air flow, increasing furnace run time and increasing both wear on the motor and energy consumption. Bertini cot instruction manual.

Filter sizing must be taken into account when designing the HVAC system to ensure that the HVAC system can handle the associated pressure drop, especially with high MERV filters. Increasing the filter surface area will decrease pressure drop; options for increasing surface area could include using more deeply pleated filters or larger dimensioned filters. Filters must be sized using the Air Conditioning Contractors of America (ACCA) Manual D (). For more information on furnace filter types, MERV ratings, and sizing, see the guide.
