Frying odor lingers because aerosolized grease settles on range hoods, filters, cabinets, fabrics, and dust, not simply because the air smells during cooking. Ventilation helps at first, but removing the greasy film is what prevents the odor from returning.
Ventilate during cooking and immediately afterward
Use a vented range hood when available and open windows when outdoor air is suitable. A recirculating hood does less for vapor and odor when its filters are saturated, so filter maintenance matters.
Clean the hood and greasy surfaces first
Degrease washable filters according to the manufacturer and clean backsplashes, cabinet fronts, and nearby surfaces with a compatible product. Do not mix degreasers with bleach or other chemicals, and keep motors and electronics dry.
Wash fabrics that absorbed the odor
Curtains, table linens, covers, and towels can retain oily compounds. Wash according to care labels and clean upholstery with a material-appropriate method; adding fragrance without removing residue only masks the smell.
If the odor returns when cooking starts, look for hidden grease
Check filters, cabinet tops, and areas around the cooktop where greasy dust collects. An electrical burning smell, melting-plastic odor, or visible smoke should not be treated as ordinary frying odor: shut the appliance off and investigate the cause.
