Ventilation grills protect a building's heating and cooling system by keeping large objects from entering the ductwork. Most of them are square- or rectangular-shaped metal or plastic sheets with an array of slits that allow air to circulate freely. Metal grills are usually held in place by screws in each of their four corners; plastic grills are usually held in place by plastic snaps. They all require periodic cleaning because they collect dust and other airborne debris. Cleaning them is a simple housekeeping task that is neither overly messy nor labour intensive.
