According to the manufacturer, the filters can be used by businesses seeking the Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ and may help qualify for one LEED point under “EQ5: Indoor Chemical and Pollutant Source Control.” The filters are available as a field-installed accessory for L Series® and S-Class™ rooftop units.
