Which air purifier is better? Recommended types of air purifiers

With the increasingly serious environmental pollution problem, more and more families began to use air purifiers, and various air purifiers began to appear in the market. So among many kinds, which air purifier is better? Below, we recommend the types of air purifiers for you, hoping to help you.

Which air purifier is better?

According to the removal technology of particulate matter in air by air purifier:

1. Mechanical filtration: Generally, particles are captured in the following four ways: direct interception, inertial collision, Brownian diffusion mechanism and shielding effect. Good collection effect on fine particles, but large wind resistance. In order to obtain high purification efficiency, the resistance of the filter screen is large, and the filter screen needs to be compact, which leads to a decrease in service life and needs to be replaced regularly.

2. High-voltage electrostatic dust removal: a dust removal method that uses high-voltage electrostatic field to ionize gas and make dust particles charged and adsorbed on electrodes. Although the wind resistance is small, the collection effect of larger particles and fibers is poor, which will cause discharge, troublesome and time-consuming cleaning, easy to produce ozone and form secondary pollution. "High-voltage electrostatic dust removal" is a way to ensure air flow and absorb fine particles. This is a way to charge the particles by loading high voltage before they pass through the filter element, so that the particles are "easily adsorbed" to the filter element under the action of electricity.

3. Electrostatic electret filter: Compared with mechanical filtration, it can only effectively remove particles above 10 micron, and when the particle size is reduced to 5 micron, 2 micron or even submicron, the efficient mechanical filtration system will become more expensive and the wind resistance will increase significantly. By filtering with electrostatic electret air filter material, high collection efficiency can be achieved under the condition of low energy consumption, and at the same time, it has the advantages of electrostatic dust removal and small wind resistance, but there is no need to externally connect tens of thousands of volts, so ozone will not be generated, and it is convenient to discard because it is made of polypropylene.

4, electrostatic dust removal: can filter dust, smoke and bacteria smaller than cells, prevent lung disease, lung cancer, liver cancer and other diseases. The most harmful thing in the air is dust smaller than 2.5 microns, because it can penetrate cells and enter the blood. Ordinary purifiers use filter paper to filter dust in the air, which is easy to block the filter holes. Dust not only has no sterilization effect, but also easily causes secondary pollution.

5. Electrostatic sterilization: Using a high-voltage electrostatic field of about 6000 volts, bacteria and viruses attached to dust can be instantly and completely killed, and diseases such as colds and infectious diseases can be prevented. Its bactericidal mechanism is to destroy four polypeptide chains of bacterial capsid protein and damage RNA.

6. Natural air purifier: It has been proved by inspection that the crystal gypsum lamp is a natural air purifier, which has environmental protection functions such as volatilizing negative ions, adsorbing impurities in the air and shielding harmful rays from electrical appliances. What is unique is that during the day, it presents a completely natural stone texture, which is simple, simple and heavy, emitting a strong natural atmosphere and a simple and mysterious style; At night, it becomes a magician who creates a warm atmosphere, pure white crystal gypsum mine, soft and quiet lighting; Orange crystal gypsum lamp, red light has become the host's emotional appeal, lit up, romantic atmosphere around.

According to the purification requirements of air purifier:

1. Clean air purifier: If it is located in an area with moderate indoor humidity or the air quality is not too high, it is enough to choose a clean air purifier.

2. Humidification and purification type: If it is located in a relatively dry area, it is the most suitable choice to choose an air purifier with humidification and purification function because the air conditioner is often turned on, the indoor air is dry, or the air quality requirements are high. LG's future celebrity air purifier also has the technology of natural humidification, which uses scientific and technological means to vaporize water, leaves harmful substances in the tray for elimination through the rotation of windmill or disc filter, and only discharges ultra-fine and clean water molecules into the air.

3. Intelligent: If you like automatic operation, intelligent monitoring of air quality, or showing noble taste, or giving gifts needs to be more decent, then buying an intelligent air purifier is the best choice.

4. Vehicle-mounted: If it is used for air purification in the car, it needs an air purifier specially used for purifying automobile odor and automobile formaldehyde, and it can be placed in the car, so the best choice is the vehicle-mounted air purifier.

5. Desktop: The air purifier placed on the desktop is used to purify the air in 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 in a public place, it is not cost-effective or fashionable to buy a large air purifier yourself, then the desktop air purifier is a better choice.

6, large and medium-sized: mainly suitable for indoor large-scale occasions, such as home halls, senior bank offices, senior administrative offices, important lecture halls, senior hotels, hospitals, beauty salons, kindergartens and other occasions.

7. Central air conditioning system type: it is mainly suitable for installing central air conditioning, or a single room with ceiling, or multiple rooms are purified together.
