1. Electrostatic dust collection does not need to use a filter screen, so there is no follow-up cost problem; filter purifiers need to be replaced regularly, so the later investment is continuous. However, in many countries, electrostatic precipitators have long been banned for sale because they generate different amounts of ozone during use.

2. The higher the HEPA efficiency, the greater the resistance, and the actual ventilation volume of the purifier will also be reduced. When the air volume decreases, the number of purifications per unit time will also decrease, and the CADR value will decrease. Therefore, it is not that the thicker and heavier the HEPA filter, the better.

3. HEPA works by relying on the van der Waals force between fine particles and solids, so it has a very good filtration efficiency for particles above 0.5 microns and below 0.1 microns. Since the particles of 0.1 microns do Brownian motion, the smaller the particles, the better the Brownian motion. The stronger the movement is, the more times it is hit, the better the adsorption effect is, while the particles larger than 0.5 microns do inertial motion, the greater the mass, the greater the inertia, so the filtering effect is better. Therefore, it is not that the larger the volume of particulate matter, the stronger the removal ability of HEPA.

4. As long as the air purifier with activated carbon filter or similar function filter is installed, it has the ability to remove formaldehyde, but the removal speed or efficiency of some products is relatively low.

5. During the use of the air purifier, the windows can be properly opened for ventilation, but the windows cannot be kept open, otherwise the effect of purifying the air will be affected.

6. In addition to the haze we usually know about, there are many other factors in indoor air pollution, such as formaldehyde, benzene and other decoration pollutants, as well as bacteria, viruses and dust, etc. Many of these pollutants are colorless and odorless. It is difficult for us to notice, so it is recommended to turn on the air purifier when we are at home.

7. According to different air purifiers and operating environments, the replacement and maintenance of filters are also different. For example, the maintenance frequency of the newly renovated home formaldehyde filter must be higher. If it is a city with a high concentration of fine particles such as Beijing, Shanghai and Guangzhou, the HEPA filter needs to be replaced in time. It is worth mentioning that if the filter of the air purifier is not replaced, the efficiency of the product will continue to decrease.

8. Most of the air purifiers that have the problem of producing ozone at present use electrostatic dust removal technology. Although this type of purifier has a certain effect on air purification, high-voltage static electricity is easy to generate ozone during use. Once the ozone concentration exceeds the standard, people in this environment may experience symptoms such as accelerated breathing, coughing, and headaches. For consumers who have purchased the electrostatic precipitator technology air purifier, it should be noted that it should not be turned on for a long time, the opening time should be controlled between 30-40 minutes, and the air convection should be paid attention to.
