Whether you use the self-cleaning feature on your oven or a chemical-based cleaning solution, the post-cleaning aftermath can lead to a kitchen full of nasty odors and airborne contaminants that neither a range hood nor open windows will fullly remove. Eliminate them as quickly as possible with a ceiling mounted ventilation fan (note that there are certain requirements for placement of such fans away from stove/cooktop surfaces). High air movement options are available that can easily and quietly handle the job.
