Activated Carbon Odor Removal Equipment, also known as Air Purifiers, Air Fresheners, and Cleaners, refers to products capable of adsorbing, decomposing, or transforming various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde from construction, allergens, etc.), thereby enhancing air cleanliness. They are mainly categorized into residential, commercial, industrial, and building types.

There are various technologies and mediums in activated carbon deodorization equipment, enabling it to provide users with clean and fresh air. Common air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photo catalyst technology, superstructured photo mineralization technology, HEPA filtration technology, and electrostatic dust collection technology; material technologies mainly consist of: photo catalysts, activated carbon, synthetic fibers, HEAP materials, and negative ion generators. Most existing activated carbon deodorization equipment is composite, utilizing multiple purification technologies and material mediums simultaneously.
