If the smoke really kicked up you could just replace your regular filter more often to keep up the performance. I’m not that convince by the argument of “but the HEPA is much bigger”; size isn’t everything and the video shows evidence of efficacy. Which is more important to me.
Yes, HEPA isn't measured in size but its efficacy which requires certain level of filtration to be call HEPA. The larger surface area just means they last longer and due to its fiber structure need more intake to maintain same level of flow.
