1. Air purifier with photocatalyst technology
Photocatalyst technology is that nanomaterials convert light energy into chemical energy under the irradiation of light to promote the synthesis of organic matter or degrade organic matter.
Advantages: It has the functions of dust removal and sterilization, and it is a widely used technology.
Disadvantages: it must be activated by a specific wavelength of ultraviolet light to be effective. The product life is very short, and the effect is not obvious. Ultraviolet light is harmful to humans, and it is not suitable for humans and machines to coexist during purification.
2, air purifier with negative ion technology
The main principle of negative ion technology is to use static electricity to release negative ions and absorb dust in the concentrated air to reduce dust. At the same time, negative ions also ionize oxygen in the air into ozone, which has a certain killing effect on bacteria.
Advantages: Negative ions combine with soot and dust particles in the air to produce static-charged soot and dust particles. After being attracted by the ground, they will settle and play a role in purification.
Disadvantages: can not eliminate harmful gases such as formaldehyde and benzene.
3, air purifier with activated carbon technology
The activated carbon purifier has the function of dust removal and deodorization, and can also purify the air, but due to the problem of adsorption saturation, the effect is likely to be attenuated.
Advantages: can absorb peculiar smell in the air
Disadvantages: can not decompose harmful substances such as formaldehyde and benzene through physical, chemical, and biological reactions to achieve the purpose of purifying the air. Need to be replaced on a regular basis and continue to incur costs.
4. Air purifier with ozone technology
The ozone technology reacts quickly to the inactivation of bacteria, and the sterilization is very thorough, but the excessive ozone is seriously harmful to human health. It strongly stimulates the human respiratory tract and can cause adverse reactions such as dyspnea, dizziness and headache. Therefore, it is mostly used for industrial waste gas treatment.
Advantages: Low concentration of ozone can kill a variety of pathogenic bacteria, viruses, mycoplasma and microorganisms that are left in the air, water, and surface of objects.
shortcoming:
(1) Excess ozone is an invisible killer, which can cause nerve poisoning, dizziness, headache, vision loss, and memory loss.
(2) Human and machine cannot coexist.
(3) can not adsorb solid particles.
5, HEPA technology air purifier
HEPA air purification technology is a relatively mature dust removal technology at present. The HEPA filter has a filtration efficiency of 99.9% for particles above 0.3 microns, which is a safe and reliable dust removal technology!
Advantage: It is the abbreviation of higheifficencyoarticleairfilters, which means high-efficiency filter in Chinese. It is effective in filtering small particles, dust, bacteria, viruses and other substances above 0.3 microns.
shortcoming:
(1) It is easy to be damaged and cannot be washed with water. It must be replaced regularly for continuous use. Maintenance is expensive.
(2) The density of the HEPA filter is high, and a powerful exhaust and suction fan is necessary to drive the air through it, which consumes more power.
(3) can only filter pollutant particles and odors flowing through the air.
6. Air purifier with electrostatic dust removal technology
Electrostatic dust removal is generally speaking that the electric field formed by high-voltage static electricity magnetically attracts dust in the air, reducing dust and purifying the air. However, it cannot directly kill viruses and bacteria, and decompose pollutants; if too much dust is not cleaned or the efficiency of the electrostatic vacuum cleaner decreases, it is easy to cause secondary pollution. Due to high-voltage discharge, safety protection devices are required, and it is generally not suitable for use in large public places or indoor places that require high disinfection conditions. It is best not to use it for civilian use.
Advantages: easy to use, after one or two weeks of use, black dirty water can be washed out, slowing down and reducing secondary pollution. There is no need to replace expensive consumables. And can be electrostatically sterilized. The electrostatic tungsten wire releases 6000 volts high-voltage static electricity, which instantly kills bacteria, viruses and pollen. It is extremely effective for eliminating colds and various infectious diseases.
