What technologies do air purifier manufacturers need to have to produce purifiers?

  • January 06, 2022

Many people don't know what technical support the air purifier manufacturer needs. The following is the answer from Shenzhen Xiluo Technology, a professional manufacturer of air purifiers.



1. Electrostatic dust removal: it can filter dust, smoke and bacteria smaller than cells to prevent lung disease, lung cancer, liver cancer and other diseases.

       The dust in the air that is harmful to the human body Z is less than 2.5 microns, because it can penetrate cells and enter the blood. Ordinary purifiers use filter paper to filter the dust in the air, which can easily block the filter holes, and the more dust accumulates, not only has no sterilization effect, but also easily causes secondary pollution.


2. Electrostatic sterilization: The electrostatic tungsten wire releases 6000 volts high-voltage static electricity, which can instantly and completely kill bacteria and viruses attached to the dust, and prevent colds, infectious diseases and other diseases. The sterilization mechanism is to destroy the four polypeptide chains of the bacterial capsid protein and damage the RNA.

       Low-temperature asymmetric plasma air purification technology


3. HEPA filter technology

       HEPA is the abbreviation of HighEfficiencyParticulateAirFilter (High Efficiency Particulate Air Filter). The HEPA filter is composed of a stack of sub-glass fiber membranes that are continuously folded back and forth, forming a wave-shaped gasket to place and support the filter boundary.


4. Ion wind technology

       Ion wind air purifier technology also uses more technology, but its purification efficiency remains to be verified. The ion wind air purifier is designed to adsorb particles on the charged metal blades in the purifier. The blades push the air through the components to form an air flow. The negative ions and positive ions attract each other, and the particles and smoke in the air are attached to the blades.

Negative ion

       Negative ions are negatively charged gas ions in the air. Most of the free electrons generated by the ionization of air molecules under the action of high pressure or strong rays are obtained by oxygen. Therefore, air anions are often collectively referred to as "negative oxygen ions". . The molecular formula of anion is O2-(H2O)n, or OH-(H2O)n, or CO4-(H2O)n. The environmentally friendly air anions mentioned here mainly refer to the first two small molecule anions.


5. Activated carbon

       Activated carbon is a very small carbon particle with a large surface area, abundant micropores, and strong adsorption capacity. Because the surface area of the carbon particle is large, it can fully contact with gas (impurity). When these gases (impurities) are adsorbed by the micropores, they play a role in purification.


6. Photocatalyst

       Photocatalyst, also known as Lightcatalyst, is a type of semiconductor material represented by titanium dioxide (TiO2), which does not change by itself under the irradiation of light, but can promote chemical reactions, and is a general term for semiconductor materials with catalytic function. Under the irradiation of the light source, it can use the energy of a specific wavelength light source to produce a catalytic effect (redox reaction), so that the surrounding oxygen and water molecules are excited into active OH^- and O^2- and other free ion groups, these free radicals Almost all organic substances and some inorganic substances that are harmful to the human body or the environment can be decomposed.


7. Formaldehyde scavenger

       High-end bioengineering technology originated from Europe, based on the principle of formaldehyde absorption by certain plants, extracts essence from dozens of natural plants, adds active ingredients and is refined by a special process; this product is an aqueous liquid, colorless, odorless, and odorless. No volatility (except moisture), it can actively capture free formaldehyde and form a stable solid substance. Once used, the effect is rapid and long-lasting.


8. Ozone (active oxygen technology)

       The thick layer of gaseous ozone is bluish with a special smell, and when the concentration is high, it smells like chlorine; liquid ozone is dark blue, and solid ozone is purple-black.


9. Ultraviolet rays

       Ultraviolet rays are the general term for radiation with wavelengths ranging from 0.01 to 0.40 microns in the electromagnetic spectrum, and cannot cause people's vision. In the electromagnetic spectrum, the wavelength is 0.01~0.04 micron radiation, which is the radiation from the violet end of the visible light to the X-ray.

       Ultraviolet rays with a wavelength of 200 to 290 nm can penetrate the cell membranes of bacteria and viruses, damage nucleic acid (DNA), and make cells lose their ability to reproduce, achieving a rapid sterilization effect. Short-wavelength ultraviolet light with a wavelength below 200nm can decompose O2 molecules, and the generated O* combines with O2 to produce ozone O3. Ultraviolet rays and ozone have a strong ability to oxidize and decompose organic molecules including malodors, and the synergistic effect of the combined use of UV/O3 exerts a powerful force in air purification treatment.
