    Back in my glory days, we determined that the most effective way to control dust in TV transmitters was by using negative pressure ventilation.
    The cooling air was pulled from the cabinet ceilings with air filters on the doors.
    Most TV transmitter sites were like dust bowls, you couldn't keep anything clean and this method seemed to work.
    If there were an inlet air filter and an exhaust fan from the shack venting back into an adjoining room, even a slow, quiet fan, just enough to move the air and create a small negative pressure in the shack, it might help with dust and not disrupt the heating/cooling temps.

    There is a return air vent in the room and of course the inlet vent in the floor. I live rural, in a forest. One would not think much dust is out in the woods but it is. I have a couple of night vision cams and the infrared really shows the dust floating around out there, even in the winter while its wet out. The air purifier has made a difference in a week or so with dust being on the equipment. It's not all gone but its reduced noticeably. RAC

    That is precisely what I do regularly... in a manner of speaking... Though I am a relatively new ham, I've been a lifelong wannabe and general technical nerd. Even before the radios, my man cave had an unreasonable number of computers and other electronic things to confuse and befuddle my then wife. Living in the dry farm lands of southern Idaho, dust gets in EVERYTHING and there's just no real way to prevent it short of building a class A clean room and demanding protocols for entry and exit.

    I got used to taking my equipment apart ever 1 to 3 months and taking it out to the shop to use the compressed air to blow the crap out of the cooling fins, fans and keyboards. Even now that I live in the relatively moist Puget Sound, we have our own unique dust generators and regular blow outs are still required. As NN4RH pointed out, there are a LOT of sources for dust.

    There is one thing you might try... They aren't cheap, but have you considered an electrostatic air cleaner for your house instead of the hepa filters?

    If you have cat(s) and/or dog(s) you'll never win... It's a constant battle. Every day have to dust and sweep the floors.

    That's a great idea, what about the water bill? Isn't that two words?
