Evaluates air-cleaning technologies' effectiveness and safety in indoor environments, suggesting improvements for health management.
Key Points
This research aims to develop a framework for assessing indoor air-cleaning technologies by evaluating their benefits and risks.
Developed a multi-criteria decision-making (MCDM) framework for air-cleaning technologies.
Integrated four dimensions: pollutant removal performance, byproduct formation risk, operational requirements, and economic cost.
Normalized and weighted twelve quantitative criteria using the Analytic Hierarchy Process (AHP).
Mechanical filtration technologies, especially HEPA filtration and activated carbon adsorption, achieved the highest Health and Safety Performance Index (HSPI) scores.
Ionization, ozone generation, and plasma technologies ranked lower due to higher safety penalties and operational trade-offs.
Some air-cleaning technologies may generate secondary pollutants, like ozone, raising health concerns.
