Watch this outstanding video/simulation showing how MERV 13 filters in a #corsirosenthalbox can outperform a HEPA air cleaner! It is Filter + Fit + Flow!

@JimRosenthal4 What are the units on the time scale in that video? 249 *what* ? 249 seconds?
@JimRosenthal4 If the measured CFM output of a hepa and merv 13 are identical, would effectiveness be significant (>10%). ie 800cf room, 200cfm units. If 20min for merv13 to clean room, would hepa take 18min?
