How do I remove and reinstall the ifD® Particle Filter?

Press down on the tab on the rear grille and pull the grille down toward you to remove it. Hold the air cleaner steady with one hand and grasp the ifD® Particle Filter with your other hand to pull it out. To reinstall, insert the filter at the bottom and push it in as far as it will go until you hear an audible click. (Page 4)
