The invention discloses a Binchotan-added activated carbon filter material for air conditioners. The Binchotan-added activated carbon filter material is characterized by being prepared from the following raw materials, by weight, 135-145 parts of cocoanut active charcoal, 10-15 parts of Binchotan, 2-3 parts of potassium hydroxide, 3-4 parts of brown sugar, 12-14 parts of zeolite powder, 7-9 parts of meerschaum powder, 3-5 parts of seaweed meal, 1-2 parts of sodium alginate, 1-2 parts of D-sodium erythorbate, 4-6 parts of sodium chloride, 4-6 parts of an adsorbent-aid and a proper amount of water. Apart from the addition of components such as zeolite powder, meerschaum powder and the like that enhance the adsorbing effect, the component Binchotan is also added, enhancing adsorptivity of activated carbon, releasing negative ions, blocking electromagnetic wave and appropriately adjusting indoor humidity. The component Binchotan has an excellent health-care effect. In cooperation of the adsorbent-aid, adsorption efficiency is enhanced, and indoor harmful gases are removed rapidly to make the air indoors fresh and pleasant. The preparation process is simple, and the activated carbon filter material has long service life and can repeatedly be used.
