Air Purifiers

I’m looking for something to take care of dust - a dust magnet… We don’t have any alleries but we have plenty of dust…We’ve tried fancy furnace filters, mopping(we’re mainly hardwood& tile) and vaccuming. We have an upright vac that uses bags…Maybe a better vac would help??? Maybe we need to get our ducts cleaned??? At certain times during the day when the sunlight shines through the windows, its amazing and discusting at how much dust there is in our house…Its just two adults, no pets…I’d say we’re pretty clean people…lol. I’ve heard that some purifiers are basically a bunch of crap and others are rediculously espensive. We want something that sucks…the dust…My thought was maybe under 0 and hopefully rotate it around the house every day or so…? 1200 sq ft house plus full finished basement w/ area rugs. Btw, there is no dust in the basement - less activity and only two ducts..& one cold air return duct. Hmm. Anyway, like I said , I just want to get rid of the dust
