Activated Carbon Odor Removal Equipment, also known as "Air Purifiers," "Air Fresheners," and "Cleaners," refers to products that can absorb, decompose, or transform various air pollutants (usually including PM2.5, dust, pollen, odors, formaldehyde from装修污染, allergens, etc.), improving air cleanliness. They are mainly categorized into residential, commercial, industrial, and building types.

Odor removal equipment using activated carbon incorporates 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, ultra-structured 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. The current activated carbon odor removal equipment is often composite, utilizing multiple purification technologies and material media simultaneously.
