What is negative ion technology? Why are so many companies using it?

Negative ion technology is an advanced technology applied on many products such as air purifiers, air conditioners, air conditioners,... So what is negative ion technology and how does it work? Let's find out with Dien May XANH in this article!


1 Introduction to negative ions

What are negative ions?

Air is made up of a multitude of molecules, atoms, when these atoms or molecules are lost or affected by electromagnetism, they will turn into electrically charged particles, called electrical charges or ions.

An ion that carries positive (+) charges when it loses one or more electrons is called a cation or positive ion, an ion that has negative (-) charges when it gains one or more electrons is called an anion or negative ions .

Negative ions born in nature

Negative ions are naturally formed in waterfalls , or after storms , under the effects of gravity, creating pressures that cause water molecules to decay .

In addition, in the forests , the tips of the branches of the trees where photosynthesis takes place, forming the photoelectric effect, causing ionization of the air and the formation of negative ions. Negative ions in nature are also created from thunderstorms, storms ,… Lightning and lightning release a large amount of negative ions in the air.

Density of negative ions in air, environment:

Environment Negative ion content (negative ions/cm3)
In the forest, humid area 100,000 – 500,000 VND
On the high mountains, the coast 50,000 – 100,000 VND
Suburbs, field areas 5,000 – 10,000 won
In the park in the city 1,000 – 2,000 won
In room 40 – 50 or even 0

Artificial Negative Ions – Negative Ion Technology

Not only created in nature, negative ions can be generated by humans by high voltage , electrolysis (also known as ionization) of the air to create negative ions. In particular, materials such as igneous rocks , minerals, seaweed and lava containing albumin … are capable of emitting negative ions very high.

Many scientists have researched and found a method to apply scientific techniques and process these materials into fine powders , which are then combined with macromolecular materials to create negative ions and be applied. Widely used in the fields of textile, paper plastic products, and air purification products.

2 Benefits of negative ions for health

Negative ions have been widely used around the world, for example, the US Food and Drug Administration (FDA) has certified ions as a very effective anti-allergic agent.

In March 1999, Good Housekeeping Magazine published an experiment using a negative ion generator to remove smoke, resulting in most of the smoke being eliminated by negative ions. According to a recent study by the US Department of Agriculture, negative ions can reduce the amount of dust and bacteria in the room by 52% and 95%.

Negative ions have many good effects on human health

In the cell contains a lot of mineral ions such as calcium, sodium, potassium, … and in the process of operation will generate bioelectricity. The process of ionizing minerals will help increase metabolism, increase oxygen in the blood and support the functioning of the nervous system.

Also according to a study by the US National Institutes of Health, the negative ions generated can help reduce pollutant particles in the air by up to 97% within a distance of 1.5 meters or less.

With the above attractive benefits, now negative ion technology has been used by many companies on their products from: water purifiers, air purifiers, air conditioners, air conditioner fans, …

3 Current negative ion generating products

Air purifier produces negative ions

The air purifier products on the market today, in addition to the air filter function, are also integrated with negative ion technology . For example with brands with technology .

create negative ions

Ion-generating air conditioners can be used to purify the air and balance the moisture of the skin. For example, with our technology, it is possible to create more than 3 million negative and positive ions that envelop bacteria, viruses and water molecules that form OH radicals in the air.

These OH radicals move to every nook and cranny of the room. They will combine with potentially harmful agents, including harmful odor molecules in the air, and convert into harmless water molecules. As a result, the air is completely purified.

Air conditioners , LG, Sharp , now all have applied ion generation technology and actually help improve the quality of life and air quality for users.

Air conditioning fan generates negative ions

Some high-end products of the line are also integrated with the feature of emitting negative ions . With a lower investment cost than buying an air purifier, this is a very reasonable choice when you are looking to buy a versatile product that has the function of creating negative ions.

Brands that have integrated negative ion technology in air-conditioning fans such as: , , , ,… help to meet the needs of users well.

Negative ion generator lamp

This is also a device that creates negative ions during use. Using light to separate molecules in the air into negative ions with the ultimate purpose of disinfecting the air , making up for the lack of ions for the body.

The advantage of the negative ion generator is that the device is easy to use , good for health, but has low power , is easy to damage if operated continuously, and the ability to generate negative ions is still limited .

LED lights generate negative ions and kill bacteria.

Negative ion generating bricks

New advanced technology from Europe has just entered the Vietnamese market a short time ago.

Raw materials are fired at a temperature of 1,100 – 1,200 degrees Celsius with enamel, firmly adhered to the enamel surface, without scratches , wear and tear in the previous stage, while walling and during use.

The existence of negative ion-generating materials in the glazed surface of the tile is permanent , so the tile's function of helping to clean the air with negative ions is very long.

Amy ion bricks create negative ions good for health.

Negative ion generator

As the name suggests, the product has only one function, which is to generate negative ions, besides adding oxygen in the air.

Products meet the needs of users, the price is usually quite cheap. However, customers have not yet tested the quality, along with the large price difference between brands, so customers are confused when learning about the product.
