The concept and role of negative ions
✪ conceptual
In the natural environment, among the various gas molecules that make up the air, oxygen and carbon dioxide molecules have a greater ability to "capture" free electrons, and oxygen accounts for a larger proportion of the air, so most of the free electrons generated by air ionization are "captured" by oxygen molecules, forming negative oxygen ions, or anions. The formation of negative oxygen ions, or anions for short.

Negative ions are a kind of negatively charged gas ions in the air, negative ions can not only contribute to the synthesis and storage of vitamins in the human body, strengthen and activate the physiological activities of the human body, the human body and other biological life activities have a very important impact, so it is also known as "air vitamins". It is like food vitamins, the human body and other biological life activities have a very important impact, and some even think that negative air ions and longevity, called it "longevity factor". Negative air ions are known as vitamins in the air, which can degrade and neutralize harmful gases in the air. It can regulate human physiological functions, eliminate fatigue, improve sleep, prevent respiratory diseases, improve cardiovascular and cerebrovascular diseases, lower blood pressure, improve appetite, and enhance skin elasticity.
The air is good after a thunderstorm because the gas molecules in the air after a thunderstorm dissociate into negatively charged negative ions under the action of lightning. Negative ions move in the air in a "Z" shape. And transport negative charge to bacteria, dust, smoke particles and water droplets, etc., the charge and the particles combined with the aggregation of the ball and sinking, so as to achieve the purpose of purifying the air. Negative ions have the dual function of health care and environmental protection, so as to alleviate mental fatigue, improve the role of the spirit.
We feel in the forest, waterfalls, the sea and other natural environments in the air is particularly fresh, is because of the increase in negative ions in the air, the higher the concentration of negative oxygen ions in the air the better the air quality.
Concepts and healthcare principles of small particle size negative ions
✪ conceptual
The human body has a health care role is the small particle size of negative oxygen ions. Because only small particle size anion is easy to pass through the human blood-brain barrier, play its biological effect.

Negative oxygen ion has a health care role. Mainly because the negative oxygen ion has antioxidant (reductive) anti-aging prominent role, and negative oxygen ion antioxidant (reductive) is a basic chemical principle, the chemical reaction is the exchange of electrons on the electronic layer, the loss of electrons is called oxidation, get electrons is called reduction, loss of electrons molecules (groups) or atoms show positive electrification is called positive ions, to get the excess electrons molecules (groups) or atoms show negative electrification is called Negative oxygen ions. Therefore, negative oxygen ions with negative potential, that is, there is an excess of electrons, can be supplemented to the aging cells or blood cell electrons. Thus realizing the role of antioxidant anti-aging, reducing free radicals.
Negative oxygen ions are oxygen ions that gain excess electrons. In the organism, the electron of lipid is seized, it will be oxidized into age spots; the electron of protein is seized, the cell function will be out of order; the electron of gene is seized, it will get cancer. In living organisms, this kind of electron-robbing material is called "free radicals", from the level of quantum medicine, electron is robbed is the source of all diseases. Similarly, iron rust, stone weathering, plant decay, are the result of oxidation. Negative oxygen ion with a negative potential, that is, there is an excess of electrons, electrons added to the free radicals, free radicals are reduced that is, eliminating the free radicals, and their own transformation into oxygen molecules O2.
Negative Ion Dust Removal Principle
- When the concentration of negative oxygen ions in indoor air reaches 20,000 per cubic centimeter, the amount of airborne dust will be reduced by more than 98%. Excellent effect on PM2.5, a lung-enterable particulate matter.
- Negative oxygen ions can take the initiative to capture the air with positively charged small particles of dust, so that it cohesion and precipitation, effectively remove particulate pollutants in the air, negative oxygen ions on the purification of air is derived from the negative oxygen ions and airborne bacteria, dust, smoke and other positively charged particles combined and aggregated into a cluster to land and achieve the purpose of air purification.
- Negative ions can coalesce and settle fine particles, which has been proved by the U.S. Environmental Protection Agency (EPA) laboratory experiments.
- Negative ions just particles cohesion settlement and can not be removed, encountering people walking, etc. will be raised again, to a certain extent, this statement is also right, as if the market filter air purifier is just particles intercepted adsorption in the filter, and can not be completely removed the same reason. Just small particles coalesced into large particles of harm to the human body will be greatly reduced, for example, can enter the lungs particulate matter PM2.5 is only 1/20 of the size of the hair, our eyes are invisible, it can penetrate the nasal hair, respiratory mucous membranes and other barriers of the human body to arrive at the lungs deep blockage of the alveoli, the shadow of the lungs of the ventilation and ventilation function. However, under the action of negative ions, it will coalesce into large particles and settle on the ground, even if it is lifted up again by external forces, at this time, it will become visible particles because of its large size, these particles tend to be blocked by the nasal hairs, respiratory mucous membranes and other barriers, and discharged from the body through snot, sputum, etc., which will greatly reduce the harmfulness.
Negative ions sterilization deodorization principle
Formaldehyde is a toxic substance, containing a positive charge, that is, positive ions, itself is unstable, when the human body, plants and other living organisms after contact with the cells will cause damage, the result will make the human body organisms weakened, and immunity to a decline in the disease will take advantage of the weakness.

Negative ions can remove formaldehyde. Negative ions are oxygen atoms with extra electrons, and they are produced by water, air, sunlight, and by the influence of the earth's radiation. Research has shown that negative ions have good purification and dust removal, disinfection and sterilization, can increase the concentration of negative ions in indoor air, purify the air. When formaldehyde is removed, it can decompose formaldehyde into carbon dioxide and water, so that they can be discharged outdoors with the airflow.
Problems with current mainstream air purification products
Air purifiers produce ozone in the case of negative ions, electrostatic dust collection, photocatalysts, ultraviolet lamps and other technologies. These technologies are mainly used in domestic purifiers on the more, one is the low cost, the second is the domestic environmental regulations on the release of ozone air purifier requirements are more relaxed. Europe and the United States environmental regulations are very strict, European and American origin of the air purifier will not be allowed to have ozone production, that is, not allowed to use the above several types of air purification technology that may produce ozone.
As for the dangers of ozone, there are definitely some. Whether it's a big deal or not depends on how much is produced and how long a person spends in this sub-polluted environment or not. It may be that the amount of ozone from a particular purifier meets the national standards. But it's one thing to meet the standard, it's another thing to know how long you'll be in this ozone-laden room. The National Department of Health has set the safe concentration of ozone at 0.1 ppm, and the Labor Protection Department has set a limit of 10 hours of work at the safe concentration. If you work and live in this environment all year round, it will be more harmful over time. Therefore, in the foreign air purifier industry, the purification technology that may produce ozone is no longer used.
At present, the mainstream technology of the international air purification industry is pure physical filtration technology, pure physical filtration technology does not produce ozone. California, the United States Foley Air Capital Board (ARB) in the certification of air purifiers into two categories, a selection of physical filtration, usually does not generate ozone; a class is classified as "other" skills, may generate ozone, but after testing less than 0.05PPM.
The "World Ozone-Free Certification" claimed by many brands of air purifiers is actually categorized as "Other". The so-called "zero ozone" of these products is simply that the concentration of ozone produced during operation meets the requirements of the ARB's "other" category. The problem of ozone stacking is unavoidable when used in enclosed spaces. For the harm of ozone, the authority recognized that more than 0.03ppm of ozone on the human body is very harmful, long-term breathing of such high concentrations of ozone, the human body due to the strong oxidation of ozone, the formation of sponge lungs.
Principles and Advantages of Negative Ion Honeycomb Mesh Panels
- Principle of negative ion generating material:
In 1989, Japanese scholar Kubo discovered and proposed that Tourmaline (also called Tomalin, Tourmaline) has permanent spontaneous polarization effect. Tourmaline crystals with potential difference, with a permanent charge, at the same time with the characteristics of piezoelectric effect and thermoelectric effect, without any energy, with the release of high concentration, small particle size anion, emission of far infrared rays, shielding of electromagnetic radiation, treatment of odors and sterilization and water treatment and other excellent environmental functional attributes. It does not produce ozone, does not contain radioactive substances, and will not have any impact on the human body and the environment. Its lifespan is the same as that of permanent magnet material, so it is called eco-negative ion by scientists.
- Small particle size negative ion generation principle:
Different from the principle that negative ions generated by ionization negative ion generator are generated from single-ended emitter, which is easy to aggregate and lead to negative ions with too large a particle size and loss of biological activity, the reason why the negative ions generated by this material belong to the negative ions of small particle size is that each nanosized material is equivalent to a single-ended emitter, which is dispersed to the great surface area of honeycomb mesh panel and continuously releases a large number of microscopically dispersed negative charges to combine with the oxygen molecules in the air. Combined with the oxygen molecules in the air, the atomic level of charge and individual oxygen molecules directly combined to generate small particle size anions.
Combined with high-end nano-material purification and processing technology, the nano-tourmaline material sintered on the negative ion honeycomb mesh panels is processed to the nanometer level for negative ion generating material, which has more electron holes and a greater amount of negative ion generation.

On land, the average concentration of negative air oxygen ions is 650 ions/cm3, and in forest communities, the average concentration of negative air oxygen ions is 5,000 ions/cm3, with a maximum of more than 10,000 ions/cm3.
Research to date has not found that high concentrations of negative ions have adverse reactions or side effects on the human body, nor is there a definitive conclusion on "what is the appropriate concentration of negative oxygen ions for the human body". Based on this, we believe that it is most scientific and reasonable to create a concentration of negative ions indoors that is equivalent to the natural environment that is most livable and conducive to longevity.
World Health Organization regulations:
The standard concentration of negative oxygen ions in clean air should be greater than 1500/cm3.
