FILTERS FOR COMMERCIAL BUILDINGSFiltrete filters for commercial buildings from 3M reduce energy, maintenance and life-cycle costs associated with traditional ventilation systems because of low-airflow resistance. The filters also require fewer annual changeouts. Integral seals may reduce air bypass, which can decrease particle deposits and cleaning costs for HVAC coils, ducts and occupied spaces.
