How long does the purifier take to work? At least half an hour. In the short time when the air purifier is opened, the indoor air exchange process occurs, so that the larger pollution particles originally deposited on the ground rise into the air, and the indoor air pollution does not fall. This "dusting" process lasts 20 to 30 minutes,

After that, the concentration of pollutants will decrease with the increase of the working time of the purifier. Therefore, it is recommended that you turn on the air purifier for no less than half an hour. In addition, try to keep the environment around the purifier clean and tidy. How much air volume is suitable for the purifier? Areas of the room that need to be purified. The efficiency of an air purifier depends on the amount of clean air (CADR),

The smoke purifier is how much "clean air" it provides per unit time. The larger the CADR value, the stronger the purification capacity of the purifier. Select the CADR value of the purifier = room area × room height (usually 3m) ×5/6 times (number of cycles per hour). For a space of 30 square meters, the cleanliness requirements are general, and a purifier with CADR in 500-600 is more appropriate. If a higher level of purification is required, the number of cycles per unit time should be increased.

Where should an indoor air purifier be placed? Get closer to people. Indoor air purifiers should be placed close to themselves. If people are far away from the purifier, the air quality around people will not improve as soon as possible. Wherever you are, keep a purifier near you and close doors to other unused rooms to keep the air around you clean.
