Premium CO₂ Capture Air Purifier
This is a next-generation air purification technology that improves indoor air quality while capturing carbon dioxide.
Technology Overview
Korea Institute of Energy Research (KIER)A premium air purifier that ensures safe indoor air quality and provides a comfortable learning and living environment, based on the company’s proprietary indoor CO₂ capture materials and reprocessing system technology
By incorporating a CO₂ adsorption cartridge into a household air purifier, the device absorbs carbon dioxide, and the cartridge is periodically regenerated at a regeneration station for reuse.

Technology Components
Material Technology
Compatible with existing air purifiers by using a CO₂ cartridge in place of the standard filter box
System Technology
An air purification solution that uses the new CO₂ cartridge to absorb carbon dioxide in household air purifiers and regenerates the CO₂ capture cartridges via a regeneration station


Key Features of the Technology
Indoor CO₂ Material
Selection of an inorganic-based indoor CO₂ material that complies with the Ministry of Environment’s notification (Household Chemical Products, No. 2024-89) regarding content standards for substances contained in products
Material Molding
Possesses molding technology capable of adjusting particle size (beads or pellets) and controlling strength to meet pressure drop and noise standards based on the air purifier’s airflow rate
Air Purification System
Development of a CO₂ air purifier prototype compliant with the Indoor Air Purifier Group Standard (SPS-KACA002) and performance evaluation by an accredited testing laboratory
Experimental and Demonstration Data
Construction of an 8 m³ chamber for air purifier performance evaluation
Chamber testing of an air purifier equipped with a CO₂ capture cartridge
Removed CO₂ from an initial concentration of 3,000 ppm to 170 ppm after 30 minutes
