What are the types of air purifiers and what are the types of air purifiers?

Classification of air purifiers by purification method – the details are as follows:

1. Low-temperature asymmetric plasma. The low-temperature asymmetric plasma module forms an asymmetric plasma electric field through high-voltage and high-frequency pulse discharge, so that a large number of plasmas in the air collide with each other step by step. Electrochemical reaction is produced to rapidly degrade toxic and harmful gases, living viruses, bacteria, etc., so as to efficiently kill viruses, sterilize, remove odors, eliminate smoke, remove dust, and no toxic substances are generated.

2. Chemical preparations. The main product is air freshener (car perfume), which is cheap, but it can only cover up some odors, and complex chemical reactions occur under the action of sunlight, becoming a new pollution in the car, and it is impossible to eliminate harmful gases.

3. Chemical decomposition. The main working principle is the ionizer ozone generator, which is cheap, more functional than freshener, can increase the number of negative ions in the air and reduce the solid dust in the air, has a sterilization effect but has little effect on the decomposition of formaldehyde and other harmful gases.

4. Adsorption and volatilization. It is a purifier with Chinese herbal medicine as the medium, which is low and has a certain antibacterial function, but the Chinese herbal medicine basically does not play a purification role in the solid state, and the purifier uses only a trace amount of Chinese herbal medicine ingredients, which can not only not be sterilized but also easy to become a bacterial reproduction body after saturation, and the replacement of the filter element involves the difficulty of harmless treatment.

5. Adsorption. Activated carbon filter, in a short period of time can adsorb a certain amount of bacteria and dust and harmful gases, ** cheap, can filter a certain amount of bacteria and dust has an adsorption function, but there is no choice of adsorption, the adsorption rate of water is 45%, generally a month after a saturation state needs to be replaced.

6. Multi-layer filtration. It is mainly a composite purifier, with a good filtration effect, which can significantly reduce the solid dust in the air, but it is high, and its filter device is required to be replaced after a period of use, which cannot be regenerated and has no effect on harmful gases.

7. Catalysis and decomposition. Mainly photocatalyst purifier, can decompose some harmful gases, ** is relatively low, but the current photocatalyst is still in the experimental stage of technology is not mature, photocatalyst must rely on the irradiation of ultraviolet rays in the sunlight to produce an effect, the use of ultraviolet lamps are easy to damage, frequent replacement, and ultraviolet rays are harmful to the human body and plastics.

8. Filtration adsorption. Crystalline silica molecular sieves are mainly used as filter media. The effect is obvious.

It can completely remove benzene, xylene, chloroform and other harmful gases, does not adsorb water and air, can effectively adsorb a variety of harmful gases, has a large adsorption capacity, and can be used for one and a half years of regeneration.

According to the working principle of air purifiers, there are three main types: passive, active, and active and passive hybrid.

According to the air purifier for the removal of particulate matter in the air, there are mainly mechanical filter type, electrostatic electret filter type, high-voltage electrostatic dust collection, negative ion and plasma method, etc.

According to the purification needs, air purifiers can be divided into purification type, humidification and purification type, vehicle type, desktop type, large and medium-sized, and ** air conditioning system type.

With the advent of consumption upgrading, air purifiers have gradually become the main force in improved home appliances, and there are many categories of air purifiers on the market, and many users will have doubts about not knowing how to choose. Let's take a look at what types of air purifiers there are.

1. Purification. If you are located in an area with moderate indoor humidity, or if the air quality requirements are not too high, then choosing a pure air purifier is enough to meet your daily needs.

2. Humidification and purification type.

3. Intelligent. The intelligent air purifier can be operated automatically and intelligently monitored air quality, reflecting the noble taste of the user.

4. Vehicle-mounted type. Recently, there has been an increasing emphasis on air purification in the car. If you need to specifically purify car odors, car formaldehyde and other in-vehicle pollution, and require the volume to be able to be placed in the car, then the car air purifier is the best choice.

5. Desktop type. As the name suggests, a desktop air purifier can be placed on a desktop to purify the air within a certain area around the desktop. If you often sit in front of a computer or desk, but the indoor area is not large and the ventilation is not very good, a desktop air purifier is the most suitable choice.

Nowadays, people are paying more and more attention to the problem of air quality, urban air pollution is becoming more and more serious, factories, car exhaust, etc., will cause harm to the environment. If it is not dealt with in time, even the living room will not be able to have pure air, and the person's physical condition will become worse and worse. Only under the action of air purifiers can the air be guaranteed to be pollution-free and bring health to people.

Air purifiers play an important role in improving air quality. So what are the types of air purifiers? PChouse will take you to find out.

According to the different purification methods, it can be divided into mechanical filtration, high-pressure electrostatic dust collection and other methods. Each purification method has its own characteristics, and the focus of treatment is also different, so you can choose according to your own needs.

According to the function and use: filtration: the vast majority of users who buy air purifiers hope that the air purifier can be filtered into the home room, taking the mainstream filter air purifier on the market as an example, the filtration mainly relies on the HEPA filter in the fuselage.

The specific filtration method should start from the working principle of the air purifier, through the built-in fan rotation, the indoor air is sucked into the machine, when the air passes through the HEPA filter, the particles will be intercepted by the filter, and the air is discharged through the gap of the filter, and the user will get clean air. Formaldehyde removal: If the interior has just been renovated and formaldehyde needs to be removed, you should buy a purifier with formaldehyde removal function.

Abstract: Air purifiers have now entered many homes and become a common household appliance. But what are the types of air purifiers?

What kind of people are suitable for what kind of raising needs? Today, we will take you to understand the relevant classifications of air purifiers. Next, let's take a look with Understand.com.

The specific classification of air purifiers is known, and what are the different types of air purifiers.

According to the purification needs, air purifiers can be divided into:

1. Purification. If you are located in an area with moderate indoor humidity, or if the air quality requirements are not too high, then a purified air purifier will meet your needs.

2. Humidification and purification type. If you are located in a drier area, the indoor air is dry due to frequent air conditioning dehumidification, or the air quality requirements are high, then choosing an air purifier with humidification and purification function will be the most suitable choice.

3. Intelligent. If you like to automate the operation, intelligently monitor the air quality, or reflect the noble taste, or need to be more decent for gifts, then a smart air purifier is the best choice.

4. Vehicle-mounted type. If it is used for air purification in cars, it is necessary to specifically purify car odor, car formaldehyde and other in-car pollution, and can be specially placed in the car air purifier, so the optimal choice is the car air purifier.

5. Desktop type. It is an air purifier that is placed on the desktop to purify the air within a certain range around the desktop and protect the health of people near the desktop. If you often sit in front of a computer, desk, or desk, but the indoor area is not small, or it is a public place, and it is not cost-effective or fashionable to buy a large air purifier by yourself, then a desktop air purifier is a better choice.

6) Large and medium-sized. It is mainly suitable for indoor occasions with large area, such as home halls, high-end bank offices, high-level administrative offices, important lecture halls and conference halls, high-end hotels, hospitals, beauty salons, kindergartens and other occasions.

7)**Air conditioning system type. It is mainly suitable for the installation of ** air conditioning, or the single room or multiple rooms with ceilings for purification.

Air purifiers are divided into three categories from the working principle, the first type is passive purification (filter purification), the second type is active purification (no filter type), and the third type is double purification (active purification and passive purification).

Passive purification mainly refers to the use of a fan to pump air into the machine and filter the air through the built-in filter, which can mainly filter dust, odor, toxic gases and kill some bacteria.

The principle of active sterilization can be divided into silver ion technology, negative ion technology, low-temperature plasma technology, photocatalyst technology and pure ion cluster ion technology. These purifiers generally do not have a filter design, and have no effect on removing dust and odors in the air.

The third type is the more mainstream form at present, which is the dual purification of the combination of filter screen and sterilization technology.

SKG hopes the above summary is useful to you!

There are three types of air purifiers.

1. Passive filtration: traditional physical filtration, primary effect net, deodorization net, activated carbon net, HEPA filter, mainly the fan pumps air into the machine to filter particles through the filter screen, sterilize, adsorb toxic gases and then discharge them again. In order to achieve the effect of purifying the air, there are many types of filters, such as activated carbon filters, electrostatic filters, HEPA filters, HEPA filters have better filtration effects, of course, the cost is also higher, and secondary pollution can also be avoided.

2 Active purification uses photocatalysts, negative ions, etc., mostly chemical filtration.

It is to release purification and sterilization factors into the air and actively purify the indoor air. Purification and sterilization factor technologies include anion technology, silver ion technology, low-temperature plasma technology, photocatalyst technology, net ion technology, group ion technology, etc.

3. Composite type, that is, passive plus active After the combination of passive and active, the effect is even more.

It is a combination of passive and active, usually after passive filter treatment first, after active purification and sterilization, the effect is better, but the general cost is higher.

According to the applicable scenarios, it can also be divided into household, commercial, vehicle, desktop, etc.

According to the different filters, it can also be divided into sterilization, removal, formaldehyde removal and deodorization.

According to the purification area, it can also be divided into different, such as: 20-50 square meters, 50-80 square meters, etc.

According to the brand, it can also be divided into a variety of such as, Midea, Xiaomi, Bruville, Northumberberg, etc.
