What is the scope of national standard specification of humidifier and its corresponding role

　　First, humidification capacity

　　This is the most important parameter of the humidifier. Some enterprises, in order to meet the consumers' psychological pursuit of the humidification amount, will mark the humidification amount, so the standard strictly stipulates that the humidification amount should not be lower than the nominal value of the rated humidification amount of the product.

　　Two, humidification efficiency

　　The ratio of the actual humidification capacity to the input power of the humidifier reflects the amount of humidification capacity that can be generated per unit power consumption. It is an important indicator to measure the performance of the humidifier. In order to guide consumers to buy energy-saving and environmentally friendly products and promote enterprises to develop more efficient products, the standard classifies the index into four grades: A, B, C and D.

　　Three, noise

　　Considering that the humidifier may be used in the bedroom, if the noise is too large, it will have a certain impact on consumers, so the standard has a strict limit on the noise index.

　　Four, evaporation core (device) service life

　　For the direct evaporative humidifier, the evaporative core (evaporator) is the component that has the greatest impact on the performance. With the continuous use of the humidifier, the efficiency of the evaporation core (device) will continue to decrease, and the humidification capacity will also continue to decline. According to the standard, when the humidification capacity of the humidifier is reduced to 50% of the initial humidification capacity, the evaporation core is deemed to have failed. For the replaceable evaporating core (device), its service life should not be less than 1000 hours.

　　Five, for many humidifiers with softening water, humidity display and other auxiliary functions
