Ensure that MERV 13 filters have been installed at all outside air intakes and inside air-recirculation returns.
Ensure that MERV 13 filters have been installed at all outside air intakes, with no spaces omitted.
Historically, MERV 13 filters have been more costly than standard filtration media, but the cost premium is dropping as demand increases. MERV 13 filters are now often cost-competitive if not cost-neutral.

Class-A, commercial office buildings are most likely to have mechanical systems that are compatible with MERV 13 filtration. These buildings commonly supply outside air through air handling or rooftop units and do not experience the same compatibility issues of smaller systems.
Any type of project can have a compatibility issue, but hospitality and multifamily projects are particularly challenging because they are often served by small, packaged systems.

Packaged, terminal, air-conditioning units (PTACs), are usually not physically compatible with MERV 13 filters available on the market because the filters don’t fit, and the units cannot overcome the pressure drop.

To minimize problems with pressure drop, look for filters that have a low initial resistance to airflow. Generally, the lower the initial resistance to airflow, the lower the energy use. This information can be found on product cut sheets.

Some buildings have incompatible mechanical systems. This stems from both a lack of available products that physically fit in filter housings and increased resistance to airflow, known as “pressure drop.” A MERV 13 filter’s high level of filtration removes more contaminants than traditional media, but also creates more resistance to air moving through it. Because of this, the equipment works harder and uses more energy to move the same volume of air. Some systems can’t provide the added power required to move the minimum airflow needed.
