A box fan's white noise is a soothing and constant background sound that resembles a gentle breeze. This comforting calming backdrop is created by the fan's rotating blades as they circulate air, providing a consistent and calming ambience that can help mask disruptive noises and promote a peaceful atmosphere in your living space. Whether used for cooling or simply for its white noise benefits, a white noise box fan is a versatile addition to any room, offering both comfort and tranquillity.
