Removing the Dust Filter
Remove the dust filter for a replacement.
• The dust filter is a single-use component.
• Use the dust filter (A907-FAN-F) within 6 months of buying as the shelf or storage life is less than 6
months. The ideal storage condition for a filter is a cool, dry, and dark environment. Surroundings that
adversely affect the dust filter are high heat, humidity at high temperatures, and ultraviolet light.
