During everyday cooking, tiny specks of grease lift into the air from pans on the stove. These specks come from oil heating up or food sizzling. They float upward, small and unseen amid the steam.
Over meals prepared day after day, more specks rise and settle on the kitchen hood filter above the stove. Each cooking adds a few more, sticking to the metal mesh.
The filter collects these specks quietly. One layer rests on another, building a fine, oily film across the surface. The mesh holds the growing coat without any drip or block.
Now, the filter carries this steady buildup from repeated cooking sessions. The specks merge into a slick sheen that covers more of the filter each time the stove runs.
This shows grease specks adding up in the kitchen, layer by layer, with no clear shift in how the hood works yet.
