Coway AP-1512HH Mighty Air Purifier, based on Wirecutter reviews. Home ventilation isn't as good as the office, this makes a very noticeable difference with dust and cat hair. If needed I move it to the kitchen, it cleans up heavy smoke or odor from burgers/steaks/popcorn in about 45 minutes (for a ~6000 ft^3 volume)
