Negative oxygen ions, also known as air vitamins or air hormones, play a crucial role in enhancing air quality and promoting human health. As a leading supplier of Negative Oxygen Ion Air Purifiers, I am often asked about the working principle behind these innovative devices. In this blog post, I will delve into the science of negative oxygen ion generation in air purifiers, explaining how it works and the benefits it offers.
Understanding Negative Oxygen Ions
Before we explore the working principle of negative oxygen ion generation, let's first understand what negative oxygen ions are. Oxygen molecules in the air can gain an extra electron through various natural or artificial processes, becoming negatively charged. These negatively charged oxygen ions are called negative oxygen ions.
Negative oxygen ions are abundant in natural environments such as forests, waterfalls, and beaches. They have several beneficial effects on human health, including improving respiratory function, enhancing mood, and boosting the immune system. In addition, negative oxygen ions can purify the air by attracting and neutralizing positively charged pollutants such as dust, smoke, and harmful gases.
Working Principle of Negative Oxygen Ion Generation in Air Purifiers
The generation of negative oxygen ions in air purifiers typically involves two main methods: corona discharge and the use of natural minerals.
Corona Discharge
Corona discharge is the most common method for generating negative oxygen ions in air purifiers. This process involves applying a high voltage to a set of electrodes, creating a strong electric field. When air passes through this electric field, the oxygen molecules in the air are ionized, gaining an extra electron and becoming negatively charged.
There are two types of electrodes commonly used in corona discharge ion generators: needle electrodes and plate electrodes. Needle electrodes are sharp and pointed, creating a concentrated electric field at the tip. This allows for more efficient ionization of the air molecules. Plate electrodes, on the other hand, have a larger surface area, which can generate a higher density of negative oxygen ions.
The high voltage required for corona discharge is typically provided by a power supply unit. This unit converts the low-voltage AC power from the wall outlet into a high-voltage DC power. The voltage used in air purifiers can range from a few thousand volts to tens of thousands of volts, depending on the design and specifications of the device.
While corona discharge is an effective method for generating negative oxygen ions, it also has some drawbacks. One of the main concerns is the production of ozone as a byproduct. Ozone is a harmful gas that can cause respiratory problems, especially for people with asthma or other respiratory conditions. To minimize the production of ozone, modern air purifiers are designed with advanced ozone reduction technology, such as activated carbon filters or ozone sensors.
Use of Natural Minerals
Another method for generating negative oxygen ions in air purifiers is the use of natural minerals such as tourmaline. Tourmaline is a semi-precious gemstone that has the unique property of generating negative ions when heated or subjected to pressure.
In air purifiers, tourmaline is often used in combination with other materials, such as ceramic or fiber. These materials are coated with a thin layer of tourmaline powder, which can generate negative oxygen ions when air passes through them. The generation of negative oxygen ions by tourmaline is a natural and chemical-free process, which makes it a safer alternative to corona discharge.
In addition to tourmaline, other natural minerals such as volcanic rock and sea salt can also be used to generate negative oxygen ions. These minerals contain trace amounts of radioactive elements, which can ionize the air molecules and produce negative ions. However, the amount of negative ions generated by these minerals is relatively low compared to corona discharge or tourmaline.
Benefits of Negative Oxygen Ion Air Purifiers
Negative oxygen ion air purifiers offer several benefits for improving indoor air quality and promoting human health. Here are some of the key benefits:
Air Purification
Negative oxygen ions can purify the air by attracting and neutralizing positively charged pollutants. When negative oxygen ions come into contact with pollutants such as dust, smoke, and pollen, they attach themselves to the particles, making them heavier and causing them to fall to the ground. This helps to remove these pollutants from the air, reducing the risk of respiratory problems and allergies.

Odor Removal
Negative oxygen ions can also help to remove unpleasant odors from the air. They do this by reacting with odor-causing molecules and breaking them down into smaller, less odorous compounds. This makes the air smell fresher and cleaner, creating a more comfortable indoor environment.
Health Benefits
As mentioned earlier, negative oxygen ions have several beneficial effects on human health. They can improve respiratory function by increasing the oxygen supply to the lungs and reducing inflammation. Negative oxygen ions can also enhance mood and reduce stress by promoting the production of serotonin, a neurotransmitter that is known to regulate mood and emotion. In addition, negative oxygen ions can boost the immune system by increasing the activity of white blood cells, which help to fight off infections and diseases.
Medical Applications
In addition to their use in residential and commercial settings, negative oxygen ion air purifiers also have several medical applications. They can be used in hospitals and clinics to purify the air and reduce the risk of airborne infections. Medical air purifiers that generate negative oxygen ions can also help to improve the recovery process for patients by providing a clean and healthy environment.
