What are the advantages and disadvantages of air purifier?

What are the benefits of an air purifier? We should start with the principle of air purifier. At present, most real air purifiers adopt the principle of filtration or electrostatic dust collection, and other so-called air purifiers cannot be called real air purifiers.

The air purifier using the filtration principle filters various pollutants in the air by letting the air flow through the multi-layer filter screen inside the purifier. Electrostatic air purifier makes air flow through the high-voltage electric field inside the purifier, charging various pollutants in the air, and then the pollutants in the air are adsorbed by electrodes.

After reading the principle of air purifier, I think we can know the advantages of air purifier. What are the advantages of air purifier? Of course, it can remove all kinds of pollutants in the air and improve indoor air quality.

The air purifier removes pollutants in the air, including:

1. Various particulate pollutants: PM2.5, various suspended particulate dust, and various allergens.

2. Various gaseous pollutants: formaldehyde, toluene, various volatile organic gases, etc.

3. Various bacteria, viruses, etc.

In a word, air purifiers are made for air. As long as it is normal indoor air pollutants, it can be removed simply and effectively.

What are the disadvantages of air purifier?

Many years ago, when air purifiers just entered the domestic market, many home appliance manufacturers began to launch their own air purifiers. At that time, because there was no corresponding standard for air purifiers, many air purifier manufacturers exaggerated their propaganda, and various inferior counterfeit air purifier products were circulating in the market. At that time, the quality of air purifiers on the market was uneven, and some air purifiers had poor air purification effects, even because of the use of cheap filter materials. In use, they can not only purify the air, but also release some harmful substances, which is why people think that air purifiers have shortcomings. Fortunately, in the face of the complicated air purifier market, our country has issued mandatory standards for air purifiers, national standards for air purifiers and national standards for air purifiers, forcing many unqualified air purifiers to be eliminated.
