I guess the difference is whether the bacteria die and produce endotoxins on your HEPA filter which is circulating air though your house, or if the bacteria die in your carpet or on your countertop where it is more likely to be cleaned in the next 6 months and less likely to be recirculated as breathing air.

Regardless, I agree with you. If the filter prevents you from breathing X% bacteria and y% of bacteria produce endotoxins then your choices are

-Breathe in that extra x% bacteria and have them produce xy endotoxins directly in your lungs

-Kill the bacteria but breather in their xy endotoxins that are dispersed in the air.

Seems like a zero sum game when
