VA 23 40 00 - HVAC AIR CLEANING DEVICES Organization: VA
Date: 2012-02-01
Description: Definitions: Refer to ASHRAE Standard 52.2 for definitions of face velocity, net effective filtering area, media velocity, initial resistance (pressure drop), MERV (Minimum Efficiency Reporting Value), PSE (Particle Size Efficiency), particle size ranges for each MERV number, dust holding capacity and explanation of electrostatic media based filtration products versus mechanical filtration products.
ASHRAE OR-16-C025 - CHARACTERIZING THE IN-SITU SIZE-RESOLVED REMOVAL EFFICIENCY OF RESIDENTIAL HVAC FILTERS FOR FINE AND ULTRAFINE PARTICLES Organization: ASHRAE
Date: 2016-01-01
Description: Measurements are conducted in a controlled and unoccupied residential apartment unit located in a graduate student residence hall on the main campus of Illinois Institute of Technology. More than a dozen filters with various minimum efficiency rating values (MERV) from a variety of manufacturers have been tested thus far and we are beginning to develop an online database of these results for engineers and homeowners to use.
ASHRAE - LV-11-C052 - AIR CLEANING BY PHOTO CATALYTIC OXIDATION: AN EXPERIMENTAL PERFORMANCE TEST Organization: ASHRAE
Date: 2011-01-01
Description: The device is equipped with a pre-filter for removal of airborne particles (MERV 11). The air cleaner is intended for in-duct use, ie., integration in central ventilation systems.
ASHRAE OR-16-C024 - MODELING THE IMPACT OF RESIDENTIAL HVAC FILTRATION ON INDOOR PARTICLES OF OUTDOOR ORIGIN (RP-1691) Organization: ASHRAE
Date: 2016-01-01
Description: Estimates of annual average PM2.5 infiltration factors ranged from ~0.4 to 0.2, for filters with a minimum efficiency reporting value (MERV) of 5 and high-efficiency particulate air (HEPA) filter in the old homes respectively.
ASHRAE - OR-10-038 - ENERGY IMPLICATIONS OF FILTRATION IN RESIDENTIAL AND LIGHT-COMMERCIAL BUILDINGS - RP-1299 Organization: ASHRAE
Date: 2010-01-01
Description: Periodic measurements were made over the course of a year at each site with readily available filters with different MERV categories, as rated by the filter manufacturer. The purpose of this research was to assess how filter MERV and the corresponding measured pressure drop impact energy use in smaller airconditioning systems.
