Nowadays, our air is no longer clean and safe. Through a large amount of news reports and network exposure, more and more people are paying attention to air quality. Facing these PM2.5, bacteria, chemical pollutants and dust. Particulate matter; decoration pollution, formaldehyde, pet hair, outdoor harmful gases, etc. are all invisible killers that endanger our health. Most families choose to purchase the most direct and effective air purifier for treating indoor air environment. China air purifier market Sales share has also soared, becoming the world's third largest air purifier sales market.
Faced with a large number of products in the market with different brands, appearances and price performances, every advertisement has been promoted with the glory of the sky. It seems that as long as you pay for it, you can solve all air pollution immediately. But is this really the case? No, at present, there is no air purification technology that can solve all air pollution perfectly. Different technologies have their own advantages and shortcomings, so those that are written in a mess Language, you don't have to believe that when purchasing an air purifier, the first thing to focus on is the core technology of the product.
So how do you set aside the heavy fog, avoid the tax on the IQ, and choose a truly practical air purifier? Then, it will be deeply analyzed.
Air pollutants are more than particles and hair
Before purchasing an air purifier, it must be clear what the pollutants need to be treated. The composition of air pollutants is more complicated, but in the end it can be divided into two types: solid pollutants and gaseous pollution.
The main components of solid-state pollution: pollen, pet hair, smog, dust, particulate matter, allergens, etc., equivalent to physical attacks in the game, direct violence to the human injury, visible to the naked eye.
The main components of gaseous pollution: formaldehyde, chemical pollution, such as: benzene, sulfur dioxide, carbon monoxide, soot, etc., equivalent to the magic attack in the game, quietly eroding health.
As far as air pollution is concerned, the smog in the north is not serious. Many friends in the south feel that the air in their house is absolutely clean. But the fact is that the pollutants in the air are not only PM2.5, but also decoration pollution. Chemical pollution, tail gas pollution, PM2.5, sulfur monoxide, pollen, pet hair, second-hand smoke, etc. As long as you live in the city, even if it is just a county town, a small village can not guarantee the absolute pollution of the air.
When you are in a new house, the sound becomes hoarse, frequent cough, and conjunctival hyperemia. It may be because formaldehyde is excessive, simple ventilation, placement of green plants can not completely remove aldehydes; people in severe smog cities, masks It is already a necessity to go out, not only causes respiratory diseases such as rhinitis and bronchitis, but also causes lung cancer, affects the reproductive system and the cardiovascular system.
If the family has weak immunity, infants, the elderly, pregnant women, and the house are newly renovated, the city is foggy, the city is surrounded by chemical plants, and close to the roadside of the road. If you are raising a pet, it is recommended to buy an air purifier. Eliminate existing or hidden air pollution hazards in a timely manner.
Only by clearly knowing what air pollutants you need to solve can you compare the air purification technology more accurately, and choose an air purifier to really improve the air quality at home.
There is currently no empty net technology that can solve all pollution.
The empty net technology in the market, every seemingly decathlon, can handle everything properly, but it is not. At present, there is no purification technology that can perfectly balance both pollutants. The following are examples of several existing air purification technologies on the market, and classified according to the treatment of solid and gaseous pollution, so that everyone can understand.
Air-cleaning technology for treating solid pollutants in the air
Activated carbon purification technology
Activated carbon is made by activating carbonaceous materials such as wood, coal, and husk under high temperature and anoxic conditions. The adsorption principle is physical adsorption! It has strong adsorption to solid particles and can adsorb dust, particles and free molecules in the air. Wait.
Negative ion purification technology
Based on the application of air negative ion generator, the negative ions generated by itself are used for ion adsorption purification of harmful substances such as dust and smoke in the air. The purification effect on dust and dust solid pollutants is obvious.
HEPA purification technology
HEPA consists of a stack of continuous, pre-folded, sub-glass fiber membranes that form wavy gaskets for placement and support of the filter media. HEPA filtration is proportional to its surface area. It is also physical adsorption purification. The purification effect of dust, solid particles and odor in the air is obvious.
Electrostatic dust collection purification technology
The filter in the air is adsorbed by the principle of high-voltage electrostatic adsorption. Effectively remove particulate pollutants in the air, such as dust, smoke, pollen, soot, etc., and also adsorb bacteria. It is easy to produce ozone harmful to the human body, and has no purifying effect on chemical pollutants such as benzaldehyde.
Air-cleaning technology for treating gaseous pollutants in the air
NCCO oxygen polymerization air purification technology
The nano-scale metal oxygen polymerization reaction layer is used to catalytically oxidize harmful substances in the air, which directly decomposes water and carbon dioxide, purifies thoroughly, and has comprehensive technology, facing formaldehyde, sulfur monoxide, benzene, hydrocarbons, Chlorine gas, hydrogenated hydrogen, fluoride, and other gaseous pollutants can play a good purification role. At the same time, dust, hair, particulate matter, etc. also have a certain purification effect, without replacing the filter element, the cost performance is higher.
I hope that after reading this article, I can help a person who needs to purchase an air purifier, reasonably avoid the tax on the IQ, and purchase a truly practical air purifier.
The composite terminal is a typical representative of the connector (CONNECTOR), which is composed of a plug (female) and a socket (male) to realize the connection function. For the transfer of voltage, current and signal, this series is characterized by safe, reliable and stable contact, and is mainly used in electric power, communication, industrial control and other industries.
