If your air fryer smells like fish even when you are not cooking seafood, it can be unpleasant and confusing.
Many air fryer users notice lingering smells after cooking foods like salmon, shrimp, or other oily ingredients. Because air fryers circulate hot air inside a small chamber, odors can easily stick to the basket, tray, and interior surfaces.
Understanding why your air fryer smells like fish can help you remove the odor and keep your appliance fresh for everyday cooking.
If you want to reduce lingering cooking odors, choosing air fryers made with safer materials may also help.
Why Your Air Fryer Smells Like Fish
Several common factors can cause fish smells to remain inside an air fryer.
Cooking Seafood
Fish naturally releases oils that carry strong odors during cooking.
These oils may stick to the basket, tray, or heating chamber and continue producing a smell during later cooking sessions.
Oil and Grease Residue
Fish oils are particularly strong and can remain on surfaces even after basic cleaning.
When reheated, these oils release a fish-like smell again.
Food Particles Trapped in the Basket
Small food particles or crumbs may remain inside the basket or air fryer tray.
When heated again, these particles release odors.
Poor Ventilation
Air fryers circulate hot air internally. Without proper ventilation or cleaning, odors may remain trapped inside the appliance.
How to Remove Fish Smell From an Air Fryer
Removing fish odors from an air fryer is usually simple.
Wash the Basket Thoroughly
Wash the basket and tray with warm water and dish soap after cooking fish.
Removing oil residue prevents lingering smells.
Use Lemon or Vinegar
Running the air fryer briefly with lemon slices or a small bowl of vinegar can help neutralize odors.
Wipe the Interior
Use a damp cloth to wipe the interior walls and heating chamber once the air fryer has cooled.
Run an Empty Heating Cycle
Running the air fryer empty for 10–15 minutes can help burn away remaining odor particles.
