Development of Particle Filters for Portable Air Purifiers by Combining Melt-Blown and Polytetrafluoroethylene to Improve Durability and Performance

<div>The performance of QF evaluated using the ExpDec2 model, which examines the changes in performance between the initial value and particle loading for various particle sizes in the melt-blown (MB), glass fiber (GF), PT + MB (PM), and PTFE membrane (PT) materials. (a) The initial cycle (without loading), (b) the second cycle, (c) the fourth cycle, and (d) the sixth cycle.</div>
