Depends on the home. Different places I’ve lived in have different needs.
For dust in particular, you should consider sources of dust and airflow.
I grew up in a house with central air conditioning, so that system had a filter that needed to be replaced periodically. You can buy a variety of different filters- coarser filters last longer but let small particles through, while finer filters need to be changed more often but get the air cleaner.
I now live in a much older house that does not have central air (radiator heat, window units for AC). My wife also likes fan noise to sleep, so we bought an air purifier that we generally leave running in the bedroom and I change that filter periodically. Our basement gets bad dust because it’s unfinished with a concrete floor and rafter ceiling, and the litter boxes are down there, so we got another filter that stays on there.
Porous and soft surfaces hang on to dust. Carpets, rugs, tapestries, upholstered furniture, piles of clothes or bedding. Putting your clothes away in a closet or dresser helps. Storing extra bedding in a cabinet or closet helps. Vacuum the carpets and rugs. Don’t let dirty laundry pile up. Wash bedding regularly (every week or two). A lot of couches have removable, washable covers that are nice to wash like once a year.
Hard surfaces are easier to clean. If you put those clothes in a dresser, wipe the top of it off with a damp cloth every now and then. A broom can help with floors a bit, but wet dusting with something like a Swiffer is better. If you have rugs you can take them outside and beat them., although vacuuming is often easier. If you have carpets… You’re really screwed unless you get a vacuum.
The hardest part is decorations. Frames hanging on walls are just a pain because you simply have to wipe them down. Knick knacks on open shelves are terrible because you’ve got to pick up the thing, wipe it off, and wipe off the spot under it. Glass display cabinets are much easier to keep clean because dust will almost never get inside. As long as you keep the horizontal surface clear it’s just an easy flat thing to wipe off. Vertical glass panes will need the occasional wipe, but not as frequently and it’s still way easier than all the books and crannies of a figure or crystal or trophy or whatever else you’ve got on display.
As for prevention, I brush my hair in one particular spot in my bedroom and clean the brush out after each time. Shower regularly. Stay on top of laundry. The idea is to get skin and hair disposed of, and doing so with water tends to prevent it from getting into the air and settling as dust. Trim your nails somewhere so they will be disposed of properly. Brush your pets.
Junior year of high school, I was starting to get myself together and start interacting with girls in my class. Ended up becoming good friends with one who ended up being single a couple months before prom.
So I ask her to prom and she says “yes”. I buy the tickets for both of us (a couple hundred bucks- good thing I had a job). She bought a dress and I rented a matching tux. My plan was to ask her to start dating AT prom.
But in the time between me asking her to prom and the actual prom, some underclassman just asked her out on a date. And she said “yes” to that too. And they started dating and were BF and GF. At this point where I’ve dropped a ton of money on this prom, made plans with her friends and all their BF’s, etc.
I stand my ground. Prom happens and we have a decent time- her BF does not go. He joins us at a restaurant afterwards and it’s an incredibly awkward night.
That summer the two of them broke up and I asked her out. We dated through senior year, went to different colleges and broke up halfway through our freshman years. She had tons of guy friends who were clearly trying to date her that she always humored. She claimed they were just friends (a lot of them were ex’s) but she clearly loved the attention they, and I, gave her trying to compete for her. I’m not the jealous type but that was exhausting. In retrospect her dating another guy while in the month leading up to that prom was a huge red flag and I should have ran then.
