In newer construction, especially high-rise apartments, there’s a lot less dust. But in older buildings, it’s just an endless torrent, and the solution has been…
Robot vacuums
While they must be maintained, and won’t work well if you’re not diligent about picking up and keeping obstacles off the floor, they make it far easier to keep the whole house clean by reducing the overall volume of interior dust and debris inside the building envelope.
To illustrate (this will be gross) I change the bags about every month and weigh them and it’s usually 1 kg (2 lbs) per bag, and each year they remove roughly 30-40 kg (70-90 lbs). And every time I’ve cut them open to see what’s causing all the weight (or make sure nothing important was eaten) it appears to be mostly dust and hair.
It’s freaky thinking how all of that would be floating around, settling on surfaces, collecting in corners and crevices, saturating carpets and upholstery, and of course getting breathed in constantly. Instead I don’t have to manually dust and vacuum very often and our indoor AQI is usually better than outside.
So yeah. Robots.
