Vacuum cleaner with hose attachment
Haier dehumidifiers are available in a variety of sizes and models with slightly different features and functionality. Every Haier dehumidifer has an air filter that helps keep dust, debris and allergens out of the air that cycles through the unit. Haier recommends checking and cleaning the air filter in the dehumidifer at least every two or three weeks when the unit is being used.
Unplug the unit from the electrical outlet. Lift the water bucket by the handle and set aside.
Grasp the top of the filter toward the front of the unit. Pull the filter up and out of the unit.
Vacuum the filter with a hose attachment to remove dirt and particles.
Run the filter under clean tap water until all visible dirt and debris are gone. Dry with a clean cloth.
