. . . No . . .
If I were to open the window here, not only would I likely get bugs, but the dust from the Phx air would make my apartment worse for dust.
Change the filters in your AC/heating/ventilation system as required.
Vacuuming is a good thing to do, but alone it won't do much to help with a dust problem or alleviate allergies. Vacuums don't pull dust out of the air, only what has settled in the carpet. In keeping with that, it's probably a good idea to rent a carpet cleaner and clean your carpet thoroughly once in a while. Be sure to use some fabric softener afterwards to remove the static charge from the carpet, it will keep it from attracting dust particles and keep it clean longer.
Using a static charged duster to dust shelves and so forth would help as well.
Ultimately, though, the only way to take it out of the air is with a filter system like HEPA filter.
