How do I set up and install the filters before first use?

Before using your new air purifier, you must remove the protective wrappers covering the filters. 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, remove the protective wrap, then place the HEPA filter(s) back in with the pull tabs facing outward, place the Pre-Filter on top, and tuck its edges into the surrounding tabs before replacing the grille.
