But these “large” particles fly into a HEPA filter, they’re also major to receive through, so they get trapped. Experts Have got a title for that. When particles get caught in between two fibers, they simply call it “straining.”
The ranking is assigned following testing small, medium, and huge particle filtration — usually applying smoke, pollen, and mud. Simply how much of such components are filtered for each moment is calculated, and a CADR score is assigned based on the outcome.
