| dc.description.abstractgeneral | Clean air is essential for public health, but current air filters often come with trade-offs— they remove harmful particles effectively but cause high pressure drops and need frequent replacements. In this project, we developed a new kind of air-cleaning system. Our design allows air to flow freely through wide gaps between wires, resulting in almost no pressure drop. To capture particles, we use a process called corona discharge, which gives particles an electric charge and pulls them toward the wires. A small stream of water flows down the wires, washing the particles into a container below—making the system self-cleaning. We tested how different design choices affect how well it works. Using salt particles about 30 nanometers in size, the system was able to remove over 99% of particles from the air. Further testing with incense smoke particles, with an average size of 100 nanometers, achieved a removal efficiency of 85%. This level of efficiency is similar to large industrial scrubbers, but this system uses much less water and energy. These results suggest that this type of self-cleaning air filter could be used in many real-world situations, from industrial sites to power plants, where reliable, low-maintenance air cleaning is important | en |
