If the house feels stuffy no matter what you do, you've been solving the wrong problem.
Cleaning takes dust off the surfaces you can reach. The stuffiness isn't on a surface.
Once the windows are shut for the season, your furnace is the only thing moving air in the house, and it moves the same air every time. Carbon dioxide, cooking fumes, whatever comes off your cleaning products. It all stays in here with you until spring, and no amount of wiping counters touches it.
Two things actually change it, and neither one costs you heat.
Run your kitchen and bathroom exhaust fans all the way through when you cook or shower. They vent outside. Most people use them for smoke and steam and nothing else.
Then on the next mild day, crack a couple of windows on opposite sides of the house for five or ten minutes and let the air move through.
DM me and I'll send you the filter rating and swap schedule that goes with this, so the air has somewhere to go and something catching what's in it.
