Abstract
Environmental pollution and pandemics have demonstrated the need for solutions that can provide protection against airborne health hazards. This study explored the feasibility of an efficient but low flow resistance filter that could be used in various applications. A miniature electrostatic precipitator (ESP) with a face area of 5x7 cm and a depth of 1.5 cm was designed and constructed. Its efficiency was measured using test aerosol and a particle counter for a size range of 0.3-2 µm at an air flow rate of 1.5 dm3/s. The results showed that the efficiency was high, over 96 % for all particle sizes > 0.3 µm, while the pressure drop over the filter was only a few pascals. The electric power of the ESP was only 30 mW, making it possible to use battery powered high voltage (HV) sources. The envisioned applications are personalised, mobile ventilation solutions, and reusable personal protective devices.
