Because the pathogen that causes the COVID-19 disease is spread via a respiratory transmission (i.e., breathing in the infected respiratory droplets from someone carrying the virus), businesses and governments have employed air filtration strategies to help combat the spread of the disease.
But how do you know if an air filter works well enough to help prevent the spread of COVID-19, or to address other air filtration concerns such as eliminating common allergens from the air? Reliable air filtration manufacturers will use a MERV rating to indicate how effective their filters are. Some jurisdictions in Canada and the United States have even gone as far as mandating certain MERV ratings for public spaces to be able to reopen.
In this article, air quality experts from Camfil Canada explain MERV ratings, what MERV means, and how MERV ratings are determined.
MERV Acronym Meaning — What Does MERV Stand For?
The acronym MERV stands for “minimum efficiency reporting value.” In other words, MERV ratings are a way of indicating how efficient an air filter is at capturing particles of various sizes.
MERV ratings are represented by a number ranging from 1 to 16, with MERV-16 providing the most protection and MERV-1 providing the least.
The following table shows the efficiency of each MERV rating against various particle sizes.
