Air purifier? That’s a less than ideal term since it gets applied to stuff like ionizers that are of dubious efficacy.
But a straight up filter, hell yeah they work. Just check the filter on your furnace/heater sometime. Same with any AC unit.
If you have something that has a filter, it will reduce dust, period. Without a filter, you aren’t going to reduce dust worth a damn, if at all.
But you also need to make sure it’s turning the air over often enough. I haven’t looked the info up in ages, but if you want a decent reduction in particulates, the device has to move air fairly significantly it it isn’t going to about to much.
Like, my house is right around a hundred years old. Four humans, and various animals over the years. Shit is dusty what with the dead skin, particles from things like carpet, pollen, dander, etc. Enough stuff gets produced that even with the regular furnace/ac filter, and a handful of one-room filters spread throughout the house (which tends to be better than one big one imo) we still get dust buildup on everything. But if we don’t run the filters, you can both visibly and nasally tell the difference.
A newer house isn’t going to have as much, so you can likely get away with less air turnover, short term, and need to dust less. But you’ll never be totally dust free just because you can’t move enough air to prevent at least a little settling.
