The air purifier has H11, H12 and H13 filters. Is the higher the filter the better?Air purifier sale

　　Large filter area is of course beneficial, but the filter area is not the standard that determines the quality of the purifier. It depends on the CADR value and the household area. Mainly look at several layers of filtering devices, the size is only the applicable area of the house under the premise of good filtering function. The higher the level of the HEPA filter, the smaller the particle size (0.1~0.3) micron, but at the same time the greater the wind resistance, so it needs to be equipped with a suitable motor.

　　The so-called filter is a filter that wraps the motor through the specific structure of the purifier. When working, the filter will block most of the large particles on the surface, and then it can play a role in purification. The higher the level, the smaller the holes on the filter screen, which can block small particles on the filter screen. Although the purification ability is strong, the wind resistance will also increase, which will affect the air volume and reduce the overall purification efficiency. So the higher the level, the better. It depends on the efficiency of the entire machine.

　　HEPA filters are divided into specifications according to the filtering capacity, but products that blindly adopt high-specification filters cannot achieve good purification effects. Every time the HEPA filter specification is increased, the wind resistance generated by the hepa filter will increase, and the corresponding energy consumption will also increase (the power consumption of IQ Air is 160W). At the same time, the filter efficiency of the filter is only one aspect that affects the purification effect, and whether it can generate air volume and pressure also directly affects the purification effect. If the air resistance of the filter is too large and the flow in the filter element is slow, the purification effect of the purifier on the entire room will be reduced.

　　The more layers of filters in the air purifier, the better?

　　Different air purifiers, manufacturers will be equipped with different filters according to the purpose of purification, combined with the situation of the wind system. Some are equipped with three floors, some are equipped with five floors, and some are equipped with more.

　　How many filters the air purifier needs depends mainly on the purpose of purification, especially the matching of air volume. The quality of the filter does not have nothing to do with the number of layers, it is mainly related to the thickness and the matching of the air volume. In order to increase the air volume and reduce the density of the filter, some low-end air purifiers increase the selling point by increasing the number of layers, but in fact, the filter of each layer is very thin, and the filter does not match the air volume. Large particles can easily penetrate the hepa filter and make it ineffective when the air volume is large.

　　The filter screen is used to filter fine particles. It has nothing to do with the number of layers, density, and technology, but the density is too high and cannot be passed through. The pleated filter screen is good and the area is large, which is good for filtering the air better. .

　　Therefore, the new model can only be realized if the fan, filter and air circulation design are properly matched.
