The Science Behind the Zero2.5 Negative Ion Air Purifier

Negative air ions (NAIs) are particles in the air that carry a negative charge. They are created through a process called ionization, where molecules in the air gain extra electrons. This makes them negatively charged. The Zero2.5 purifier employs a unique method to generate these ions using a natural fiber ball as exposed electrodes, with each sharp fiber acting as a negative ion emitter. Here's how it works:

The Role of the Exposed Electrode as the Ionizer Emitter

The natural fiber ball in the Zero2.5 purifier consists of numerous sharp fibers that serve as ion emission points. These fibers act as tiny antennas, emitting electrons into the surrounding air. The sharpness of each fiber is crucial because it enhances the electric field at the tips. When a high-voltage electric charge is applied to the fibers, it creates a concentrated electric field at the sharp points. This phenomenon, called the corona discharge effect, is responsible for the ionization process.

Working Mechanism of the Emitter
  1. High-Voltage Supply: The fiber ball is connected to a high-voltage power supply. This high voltage energizes the fibers, creating an intense electric field around their tips.

  2. Electron Release: Under the influence of this electric field, electrons from the fibers are "knocked out" and released into the air. This is because the sharp edges of the fibers provide less resistance for electrons to escape.

  3. Ionization Process: These released electrons collide with neutral oxygen molecules in the air, transferring their charge and turning them into negatively charged oxygen ions.

  4. Dispersion: The emitted negative ions disperse into the environment, where they attach to airborne particles like dust, pollen, and bacteria, neutralizing them and improving air quality.

The choice of natural fibers for the electrode has added benefits. Each fiber’s sharpness and material composition make the ion emission process efficient, while the natural properties of the fibers ensure durability and eco-friendliness. This design not only ensures a consistent and high output of NAIs but also minimizes energy consumption, making the Zero2.5 purifier an innovative and sustainable air purification solution.
