Abstract
Air purifiers are essential for mitigating indoor
air pollution, which poses significant health risks. The efficiency of these
devices largely depends on the filter technology employed. This review examines
the latest advancements in air purifier filters, including High-Efficiency
Particulate Air (HEPA) filters, activated carbon filters, electrostatic
precipitators, and emerging technologies such as photocatalytic oxidation and
nanofiber-based filters. We evaluate their performance in capturing particulate
matter (PM), volatile organic compounds (VOCs), and microbial contaminants, while
considering factors like energy consumption, longevity, and cost-effectiveness.
The study highlights innovations that enhance filtration efficiency, such as
hybrid systems and smart filtration technologies, and identifies challenges for
future research, including scalability and environmental impact. This review
serves as a resource for researchers and manufacturers aiming to optimize air
purification systems for diverse applications.
