LIFESMART Deodorizing Boot Dryer: utilizes a cold plasma method to inactivate odor-causing particles: Plasma is a charged and neutral particle that carries electrical currents and generate magnetic fields. Much like sunlight or lightning does in the atmosphere. The plasma bulb produces natural streams of positive and negative oxygen ions. The negative ions contain an extra electron while the positive ions are missing an electron resulting in an unstable condition. In an effort to re-stabilize, these bipolar ions seek out atoms and molecules in the air to trade electrons with, effectively neutralizing particulate matter, bacteria and virus cells, odorous gases and aerosols, and VOCs. How the Ions Work the Smells and Germs: Airborne particles are charged by the ions causing them to cluster and be caught in filters. As they divide to reproduce, bacteria and virus cells bond with oxygen ions and are destroyed. Odorous gases and aerosols oxidize on contact with oxygen ions and are neutralized. Oxygen ions cause a chemical reaction with VOCs breaking down their molecular structure.
