Electronic filters do not have a MERV equivalency, since MERV was developed for mechanical filtration only and there is no consensus based standard for testing electronic filtration efficiency. Filtration characteristics differ substantially between mechanical filtration and electronic filtration, so there is no established MERV equivalency for electronic filtration. Electronic filters or electronic air cleaners cannot be used to satisfy EQ 7 unless the product also includes a MERV-rated media filter.
