How do I remove the protective filter wrapping before first use?

Before using your new air purifier, you must remove the wrappers covering the filters and pre-filter. Make sure the air purifier is OFF and unplugged, then press the two hand symbols on the front grille to release it and pull the grille toward you. Grasp the sides of the filter frame near its top end and pull outward, then remove the protective wrap from all filters including the pre-filter. (Page 4)
