Humidifier buying more secure implementation of the national standard
In northern China has entered the winter heating season, indoor air is dry, if not promptly drinking water or to air humidification, easily lead to the human body, dry skin, decreased immunity, affect health. This time of year,

Will show their talents, as essential household products. Reporters recently in Beijing

Marketplace interview that humidifiers have emerged hot scenes. China Standardization Committee related to official told reporters, national standards humidifier was on Nov. 1 to officially take effect, this winter, consumers will buy more layer of protection when the humidifier.
Humidifiers on the market a wide range of the most common are ultrasonic humidifier, direct evaporative humidifier, heating-type humidifier and centrifugal humidifier, and so on. Because these products with different structures and humidification principle, the limit value of pilot projects are also different, so the standard types of humidifiers and related first to a strict definition of the term.
First humidification. This is the most important parameters humidifier, some enterprises to cater to consumers seeking a large amount of psychological humidification, humidification free standard large volume, so the standard strict rules humidification products should not be rated lower than the nominal value of humidification.
Second humidification efficiency. Refers to the actual humidification humidifier and the ratio of input power, reflected power can produce the number of humidification unit volume, is a measure of the merits of a humidifier important indicator of performance. In order to guide consumers to buy

Environmental protection
Products, promote enterprise development more efficient products, the index is divided into the standard A, B, C, D four grades.
Third is noise. Taking into account the humidifier in the bedroom may be used, if the noise would be too great a certain impact on consumers, so the standard indicators of the strict noise restrictions.
Fourth evaporator core (device) service life. For direct evaporative humidifier, evaporator core (device) is the greatest impact on performance parts. With the growing use of humidifier, evaporator core (device) will continue to lower efficiency, humidification also goes down. Standard specifies when the humidifier humidification humidification reduced to the initial amount of 50%, as evaporation core failure. Evaporation can be replaced for the core (device), its life should not be less than 1000 hours.
Fifth, all with soft water for many humidifiers, humidity display auxiliary functions, in order to prevent some of the products clearly do not have this feature or this feature can not play the corresponding effect, and by means of false propaganda to mislead the consumers, the standard of these auxiliary functions are also put forward specific requirements: for the softener, the standard requiring softener softens the hardness of the water should not exceed 100mg / L (in Beijing, the average water hardness is about 250mg / L). Softener before the expiry, the total amount of water softening should not be less than 100L. The humidity display, provides the relative humidity of 30% to 70% range, the humidity display the error should be within ± 10%, in order to avoid errors but too misleading to consumers. In addition, the standard also provides some humidifiers because the water level will dramatically affect the performance, it should have a humidifier, the water level protection to prevent consumers unknowingly to humidifier in low long-term performance, low-efficiency working condition.
