　　Purification method of air purifier

　　Common household purifiers can be divided into filter adsorption type and electrostatic dust collection type. The filter adsorption type commonly used is HEPA filter, which has good purification effect and can absorb suspended particles and harmful gases in the air; The electrostatic dust collector forms a strong electric field through high voltage, generates a large number of electrons and ions to adhere to the particles in the air, and then uses the dust collector to adsorb the charged polluted particles, so as to achieve the purpose of purifying the air.

　　Electrostatic dust collection type purifier

　　The advantages of electrostatic precipitator are no consumption, quietness and low energy consumption. HEPA filter type purifiers need to replace the filter regularly. Due to the existence of motors and fans, noise and power consumption are relatively large. However, at present, the main reason for the prevalence of filter adsorption purifiers in China is that electrostatic dust removal method will produce ozone. If it exceeds the standard, it will cause harm to human body, and the external purification effect is worse than that of HEPA filter products. 　　 choosing a big brand purifier

　　In recent years, there have been more and more air purifiers. It is recommended to choose those brands that focus on air purifiers, so that product quality can be guaranteed. For some brands that we have never heard of, we must be careful. Otherwise, the problem of after-sales and replacement of the filter will not be solved, and you can only throw it away and replace it with a new one.

　　The appearance style of purifier is various. It is necessary to consider the size (when used in multiple rooms, there must be a roller), the gas path structure (related to the placement position), whether it matches the home environment, and some details, such as whether there is a child lock and whether the indicator light can be turned off (which will affect Sleep), whether to remind the filter expired, etc.

　　The higher the CADR value, the better

　　The performance of the purifier mainly depends on the CADR value, which is an index clearly marked for each purifier. The output of the air purifier refers to how high the output of the air purifier can be. The higher the value, the higher the purification efficiency. The CADR value of purifier products on sale is generally between 200-700.

　　It should be noted that the above CADR value is actually the result measured under the maximum air volume at the highest gear. At this time, the noise and power consumption are relatively large. It can be opened for a short time. Long-term use is absolutely unacceptable. Therefore, we should pay more attention to the mid-to-low CADR value. If it is too low, good indoor air conditions cannot be maintained. For example, a purifier with a CADR value of about 300 cannot maintain good indoor air conditioning in sleep mode. The air volume is small. Although the noise is low, the purification capacity at this time is also very limited.
