　　Because of the epidemic, people are paying more and more attention to air sterilizers and air purifiers, and they feel that they are very useful after their own use. Air disinfection machines focus on air disinfection, and air purifiers focus on air purification. Air disinfection machines are more used in hospitals, and can also be used in homes or laboratories with high demand for air disinfection; while air purifiers are more used in homes and offices. , so relatively speaking, the popularity of air purifiers is higher than that of air sterilizers. When people use air purifiers, they usually encounter some questions, such as does the air purifier need to be turned on all day? How long does it take to be effective? In response to this problem, the following will give you a popular science to help you improve your understanding of the use of air purifiers.

　　1. How long does the air purifier turn on?

　　According to industry insiders of air purifiers, when the air purifier is turned on, it will lead to indoor air exchange, and during the exchange process, the originally settled air pollution particles will be raised into the air again, which may lead to aggravation of air pollution. The process will take about 20 minutes. Therefore, the boot time of the air purifier is generally not recommended to be less than half an hour, otherwise it will affect the air purification effect.

　　2. Should the air purifier be turned on all day?

　　First of all, make sure that the air purifier does not need to be turned on all day, and how long it needs to be turned on depends on the air quality of the room. If the air quality is poor, the opening time should be longer. If the air quality is good, the corresponding opening time can be shorter. The air quality can be seen on the air purifier. Now many mainstream air purifiers have their own air quality detection. . When the outdoor air quality is good or it is raining, there is no need to turn on the air purifier, because air pollutants will sink when it is raining.

　　The opening time of the air purifier is also closely related to the performance of related products and the size of the room. The size of the room to be purified must match the purification space of the air purifier. For example, the purification area of an air purifier is 20-40 square meters. Using it to purify a room of more than 40 square meters may lead to poor purification effect and may lead to high power consumption. Generally speaking, the mainstream air purifiers on the market can achieve a good purification effect for about 4-8 hours. If the room area is larger, the purification time will be longer.

　　It is also worth noting that if you want to remove formaldehyde after the new house is renovated, it is not only good to use an air purifier, but a combination of window ventilation + air purifier is a better choice. Especially when the air quality outside is relatively good, and there are strong winds, at this time, the effect of directly opening the window for ventilation will be better than turning on the air purifier. When the air quality outside is poor, you can close the doors and windows and turn on the air purifier to remove aldehydes. The last thing to note is that if there is an air conditioner in the room, it is best to place the air purifier on the opposite side of the air conditioner, so as to achieve a better air circulation effect.
