SUMMARY
This discussion focuses on building an electrodynamic trap using two ring electrodes to capture aerosol particles, applying a voltage of 5 kV. The recommended distance between the electrodes should be at least 1.6 mm to prevent air breakdown, which occurs at approximately 30 kV/cm. The discussion emphasizes the importance of maintaining a safe spacing to avoid electrical sparks, particularly at sharp edges of the electrodes. Additionally, it references existing technologies such as Honeywell's electrostatic air purifiers for practical insights.
