National standard for humidifiers
One is the amount of humidification. This is the most important parameter of the humidifier. Some enterprises cater to consumers' pursuit of large humidification, and arbitrarily mark the amount of humidification. Therefore, the standard strictly stipulates that the humidification amount should not be lower than the nominal value of the product's rated humidification amount.
The second is humidification efficiency. Refers to the ratio of the actual humidification amount of the humidifier to the input power, which reflects how much humidification the unit power consumption can produce. It is an important indicator to measure the performance of the humidifier. In order to guide consumers to purchase energy-saving and environmentally-friendly products and to promote the development of more efficient products, the standard is divided into four levels: A, B, C, and D.
The third is noise. Considering that the humidifier may be used in the bedroom, if the noise is too large, it will have a certain impact on the consumer, so the standard imposes strict limits on the noise index.
The fourth is the life of the evaporation core. For direct evaporative humidifiers, the evaporating core is the component that has the greatest impact on performance. As the humidifier continues to be used, the efficiency of the evaporating core will continue to decrease and the amount of humidification will continue to decrease. The standard stipulates that when the humidifier's humidification amount is reduced to 50% of the initial humidification amount, it is considered as the evaporation core failure. For replaceable evaporation cores, the service life should be no less than 1000 hours.
