Works great and freshens air BUT you need to know that it was not disclosed in the description nor in the manual that it has IONing fans. It is just pictured in the box (see photo below). If the negative IONs produced by the air purifier doesn't matter to you or you don't think it will affect your health/lungs, then it's a great air purifier. Otherwise, I need to return it and get an air purifier that doesn't produce any negative IONs.
