Here are several ideas to keep the dust down in your home:

1. Have floor mats by each outer door and make it a practice to take your shoes off on entering.
2. Clean floors regularly.
3. Change bed sheets weekly.
4. Change air filters regularly.
5. Declutter. (Clutter allows dust accumulate.)

This is an age old question. Actually household dust comes from many sources. Dead skin cells is one source, but contrary to myth, it isn't the main source. About 60% comes from outside (through clothes and air). Other sources are carpetting and upholstery, pet dander, food crumbs, and a host of other things.  https://molekule.science/where-doest-dust-come-from-source-house-solutions/

Here is a handy hack for getting black scuff marks off of hard floors. Rub them with a clean tennis ball! (This idea provided by apartmenttherapy.com.)

So here's a thought. Craeft is about ecology. It is how humans sustain themselves in a reciprocal engagement with their local environment. But the potential for that kind of engagement is very limited in the modern world. For us, ecology is mostly a concept or an engagement with the wider world based on a concept.

For instance, I have been trying to make my business more ecologically sound by switching from microfiber cloths to natural fiber cloths. This is helpful in an ecological sense. But it arises mainly from concerns I have, after reading some articles, about the health of the oceans. We live a thousand miles from the nearest ocean. The health of the oceans does effect our own well-being here in Minnesota, but not in any way that I can measure in my daily life. 

The same is true of efforts we might take to reverse climate change or to work on a host of other environmental problems. It seems that we're sentenced, at least for the near future, to work on improving our ecological relationships to a large extent as an abstraction.
