Activated carbon deodorization equipment, also known as air purifiers, air fresheners, and purifiers, refers to products capable of adsorbing, decomposing, or transforming various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde from construction pollution, allergens, etc.), enhancing air cleanliness. They are mainly categorized into residential, commercial, industrial, and building types.

Odor removal equipment using activated carbon offers a variety of technologies and media, ensuring the delivery of clean and fresh air to users. Common air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photo catalyst technology, superstructured photocatalytic mineralization technology, HEPA filtration technology, and electrostatic dust collection technology; material technologies mainly include: photo catalysts, activated carbon, synthetic fibers, HEAP materials, and negative ion generators. Most of the existing activated carbon odor removal equipment are composite types, utilizing multiple purification technologies and material media simultaneously.
