MERV Air Filter Testing in Canada

By Phillip Ilijevski and Joe Brennan

MERV Air filter testing may not be top of mind for most people in Canada, but air filtration plays a major impact in building livability, comfort, and quality of life for occupants and visitors. Most people are likely not aware of the impact that the wrong filter can have on indoor air quality.

The information in this article is key for any industry concerned about how air filter technology affects the indoor air quality of its buildings or offices. An important factor in determining which filter to use for building managers is test results. In this article, we will take a close look at MERV air filter quality and testing and how testing in a transparent manner is crucial to evaluating and determining the efficiency of air filters.

The Evolution of MERV Air Filter Testing

Laboratory testing of air filters has been available since the 1950s. In 1968, the American Society of Refrigeration, Heating and Air-Conditioning Engineers (ASHRAE) accepted the publishing responsibility for testing. The testing has advanced over the years, adapting each new version to evolving testing technology and capability. In 1999, ASHRAE introduced Standard 52.2.

ASHRAE Standard 52.2, “Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size,” using laboratory-defined parameters, evaluates the performance of one filter against another.
