Perhaps the return air could be bubbled through a water
bath that seeped into the sewer. |

Perhaps Holy Water could be sprayed into the outlet airstream to humidify, bless the recipients*, and instantly kill any airborne pathogens ? |

*R.C. and Orthodox. Other denominations are available. As your philosophy adviser if religion is right for you. |

Hmm, my HVAC outlets are in the floor and the returns high
up on the walls. Backward. I think that's to push cold air in
at the bottom and suck out the hotter air from above. That
would mean that a top-down cooling system would be
fighting convection. Is that ideal? |

Depends on if you're heating or cooling I guess. |

Over a distance of 2.5 m and a temperature differential of (say) 10 C, the difference in density isn't going to be enough to put up much opposition to even a modestly sized fan. |

The maths of thermo-syphoning are fairly simple, and besides there will be so much turbulence and mixing that the temperature away from the inlet grille will be relatively uniform. |

Where this gets a little tricky is in the filtering; with dirty
floors becoming now an HVAC issue; the benefits may be
buried by the increased dirt intake. |

Adding a UV light in the loop would be a benefit. I'm
contemplating doing something like that to my home
system. |
