TitleSpecification(s)Objective(s)
6.6202.9a
Pre-inspection

Specifications will be field verified as appropriate to site conditions by installer

Ensure appropriate design for installation
6.6202.9b
Selection

All mechanically supplied outdoor air will pass through filter before conditioning Filters and filter racks/holders will have a rating of minimum efficiency rating value 6 or higher when tested in accordance with ASHRAE ASHRAE American Society of Heating, Refrigerating and Air-Conditioning Engineers, www.ashrae.org 52.2

Pressure drop across filter will match equipment capabilities

Filter systems that produce ozone will not be allowed 

Ensure outdoor air is filtered before entering occupied space

Ensure occupant health and safety
6.6202.9c
Installation

Filter will be located and installed to facilitate access and regular service by occupant/maintenance staff

Filter will be located on the inlet side of the equipment fan

Filter access panel will include gasket or comparable sealing mechanism and fit snugly against exposed edge of filter when closed to prevent air bypass

Filter plenum construction will be airtight and sealed to adjoining ductwork

Prevent air bypass of filter

Allow for proper maintenance and replacement
6.6202.9d
Occupant/property manager education

Occupant/property manager will be instructed on proper maintenance procedures and replacement schedule

Ensure continued performance of equipment efficiency and IAQ IAQ Indoor air quality
