How do I remove the protective wrapping from the filters before first use?

Before using your new air purifier, make sure it is OFF and unplugged, then press the two hand symbols on the front grille to release it and pull the grille toward you to remove it. Grasp the sides of the filter frame near its top end and pull outward, then remove the protective wrap from the filters including the pre-filter. Repeat for the second and third filters if applicable. (Page 3)
