Air ionization apparatus refers to a device that is designed to produce negative ions and release them into the air. These negative ions are attracted to positively charged particles, such as dust, pollen, and other airborne particles, and neutralize them, making them heavier and causing them to fall to the ground. This process is known as air ionization and is used to improve air quality in indoor environments, such as homes, offices, and hospitals. Air ionization apparatus typically use one of two methods to generate negative ions: corona discharge or radioactive decay. In the corona discharge method, a high voltage is applied to a series of needles or wires, which ionizes the air around them. In the radioactive decay method, a small amount of radioactive material, such as polonium, is used to ionize the air. The benefits of air ionization apparatus include the reduction of airborne particles, such as dust and allergens, as well as the elimination of odors and the promotion of a more relaxed and comfortable environment. However, it is important to note that air ionization apparatus should not be used as a replacement for proper ventilation or air filtration systems.
