OverviewNow elegance and performance can be combined with Nikai Weather-Shield Premium Plus Box Fan features a patented, isolated Weather-Shield motor for worry-free window use. A box fan is a portable fan that is placed within an enclosure, the face of which has a latticework plastic or steel grille that allows the air to move into and through the fan. Used in this way, the box fan helps to rid the room of smoke, dust and odors. Box fans placed in or near windows can help draw in cool air from outside or pull warm air out of a room depending on how they are placed. If the blades face the window screen, the fan helps pull hot air out of the room. Flipped the other way, it draws in air from outdoors.
