Particulate matter filters or air cleaners shall have a minimum efficiency reporting value (MERV) of 11 or higher when rated in accordance with ASHRAE Stan- dard 52. 6.2.1 Particulate Matter Smaller than 2 Microme- ters (PM2).When the building is located in an area where the national standard or guideline for PM2 1 is exceeded, particle filters or air cleaning devices shall be provided to clean the outdoor air at any location prior to its introduction to occupied spaces. 15 Note:See Appendix E for resources regarding selected PM10 national standards and guidelines. Particulate matter filters or air cleaners shall have a minimum efficiency reporting value (MERV) of 6 or higher when rated in accordance with ASHRAE Standard 52. 6.2.1 Particulate Matter Smaller than 10 Microme- ters (PM10).When the building is located in an area where the national standard or guideline for PM10 1 is exceeded, par- ticle filters or air-cleaning devices shall be provided to clean the outdoor air at any location prior to its introduction to occupied spaces. Exception:Systems supplying air for enclosed parking garages, warehouses, storage rooms, janitor’s closets, trash rooms, recycling areas, shipping/receiving/distri- bution areas Note:Occupied spaces ventilated with outdoor air that is judged to be unacceptable are subject to reduced air quality when outdoor air is not cleaned prior to introduction to the occupied spaces. 6.2 Outdoor Air Treatment outdoor air is judged to be unacceptable in accordance with Section 4, each ventila- tion system that provides outdoor air through a supply fan shall comply with the following subsections. Note:Additional explanation of terms used below is con- tained in Normative Appendix A, along with a ventilation system schematic (Figure A-1). 6 Ventilation Rate Procedure outdoor air intake flow (Vot) for a ventilation system shall be determined in accor- dance with Sections 6.2 through 6.2. Mitted to be used for any zone or portion of a zone in con- junction with mechanical ventilation systems as required in Section 6.
