Wait, so bateria that are in your home are getting sucked into the filter like they're supposed to do, die and release endotoxins. But they're going to die anyway and still release those endotoxins but it's just going to be all over my couch that I sit on every day. Ok, maybe that nasty filter you haven't changed in a year provided an environment for the bacteria to grow and the fan disperses it. Sure, I get it if it's some nasty filter you haven't changed in over a year. That's why you don't wait a year to change them. That's like saying, "Bathrooms may provide a breeding ground for mould and bacteria making your home less hygienic!." Ya, no kidding. That's why you clean your bathroom.

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
