Abstract
Air pollution, stemming from natural and industrial sources, necessitates effective air purification methods. Electrostatic air filters offer an eco-friendly alternative to high-efficiency particulate air (HEPA) filters, characterized by low pressure drop, minimal noise, cost-efficiency, and reusability. This study investigates the enhancement of electrostatic air filter performance by increasing layer count. Experimental tests in a 1×1×1 m3 chamber, using small dust particles (1 µm, 2.5 µm, and 10 µm), reveal that adding layers significantly improves filtration efficiency. Optimal layer counts of 5, 5, and 4 for respective particle sizes maintain compliance with ASHRAE 52.2 MERV Rating 14 standards. According to ISO16890 standards, these filters require maintenance or replacement after 72 cycles when efficiency falls below 60%. This research promotes wider adoption of electrostatic filters for health benefits and energy conservation.
