Premium CO₂ Capture Air Purifier

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
