IEQ3: Air Filtration Media - MERV 11 or Higher

(1 point)

PURPOSE

Improve air quality by installing high-efficiency filtration media.

CRITERIA

Increasing the efficiency of air filtration media will assist in reducing the amount of fine particulates and improve the quality of indoor air. Install air filters that have a Minimum Efficiency Reporting Value (MERV) of 11 or higher for all applicable air handling equipment. Ensure that installed equipment has capacity to handle potential pressure drop from filtration media.

If the air handlers are used during construction and/or building flush-out, project may install air filter/cleaner on all systems with a MERV 8 or higher. All filters must be replaced prior to occupancy with a minimum MERV 11 filter.

All filters must be easily accessible and provide safe and adequate clearance for maintenance. Ensure that installed equipment has capacity to handle potential pressure drop from filtration media.

Consider using a thicker media filter to increase effective surface area and reduce pressure drop.
