[0002] Air filter boxes are currently used in a wide range of applications, including those requiring a dust-free environment or for purifying contaminated air. These boxes achieve their filtering effect by installing filters within the box. Traditional air filter boxes employ a single-inlet, single-outlet filtering method, which is relatively simple and unable to deliver air in multiple directions. This results in limited effectiveness and fails to meet the needs of various purification applications. Therefore, a new air filter box has been designed to address these issues.
