How Does Plasma Air Purifier Work?

A plasma air purifier is designed based on advanced technology to improve indoor air quality by removing harmful pollutants and contaminants from the air. It utilizes a process called plasma purification or plasma ionization to achieve this.

Plasma air purifiers create an electrical field that generates positive and negative ions. The ions attach to airborne particles and volatile organic compounds (VOCs). The attached ions then become charged and are attracted to collection plates within the cleaner.

Working of the plasma air purifier

A plasma air purifier, also known as an ionizer or an ion-generating air purifier, operates by utilizing electrical charges to remove contaminants and improve air quality. Here's a general explanation of how a plasma air purifier works:

Ionization

The air purifier generates a high-voltage electrical field or uses an ionization needle to create negatively charged ions (anions) or positive and negative ions (bipolar ions) in the air.

  • This electric field ionizes gas molecules, typically oxygen or ambient air, turning them into ions.
  • A corona discharge is created when the electric field reaches a critical level, causing the air molecules near the electrodes to become highly energized.
  • As the corona discharge occurs, the positively charged ions generated in the process are attracted to negatively charged particles present in the air, such as dust, allergens, bacteria, and viruses.

Ion attraction

These charged ions are released into the surrounding air. They seek out and attach themselves to airborne particles, such as dust, pollen, pet dander, mold spores, and other allergens, pollutants, and microorganisms.

Particle agglomeration

As the ions attach to the particles, they charge them and cause them to cluster together. This process is called aggregation or coagulation. The charged particles grow larger, making them easier to capture and remove from the air.

Electrostatic precipitation

The air purifier typically contains metal plates or collection electrodes with an opposite charge to the ions. These plates are located near the ionization source. The charged particles are attracted to these plates and stick to them due to electrostatic attraction. This process is known as electrostatic precipitation.

Removal of particles

The accumulated particles on the collection plates can be periodically cleaned or washed off to maintain the air purifier's efficiency. Some models have self-cleaning mechanisms that automatically remove the particles from the plates.

Air circulation

The charged ions attached to the dust particles clean up the air and circulate the clean air back to the room.

It's important to note that plasma air purifiers primarily target solid particles and particulate matter in the air. They are ineffective at removing gases, odors, or volatile organic compounds (VOCs) from the air.

Combining a plasma air purifier with other filtration technologies like activated carbon or HEPA filters is often recommended for comprehensive air purification.

Additionally, while plasma air purifiers can help improve air quality, they produce a small amount of ozone as a byproduct.
