Use a combination of tapping and compressed air to dislodge dust from the filter pleats. You can tap with your hands or a plastic mallet on the outside of the filter. Don't get too crazy or you will dent the filter. Tap all around and the whole length. Two or three minutes of tapping will probably be enough unless the filter is really dirty. Compressed air from the hose reel above the assembly table can also be used. Spray the air all around the filter, keeping the nozzle an inch away from the mesh of the filter. Closer than that or using > 90 psi air pressure can damage the filter material. Replace the white cap and turn on the filter. IF the pressure is 1.25" or less you're done. | Use a combination of tapping and compressed air to dislodge dust from the filter pleats.
