In some embodiments, the wet curtain 4 may be a HEAP filter screen or made of wet filter paper, preferably a HEPA filter screen. The HEPA filter screen can remove particles with the diameter of more than 0.3 micron by more than 99.97 percent, thereby playing a role in filtering air flow and improving the cleanliness of humidified air.

In some embodiments, the distance between the fan 2 and the electric heating element 3 is 8 mm to 25mm, for example, 12mm, 16mm, 20 mm. The inventor of the present invention found through research that an excessively large distance between the fan 2 and the electric heating member 3 may increase the size of the entire mist-free humidifier, which may affect compactness, and an excessively small distance between the fan 2 and the electric heating member 3 may cause the fan 2 to be susceptible to aging and a reduced life due to heat generated by the electric heating member 3, and thus the above distance range is preferable.

In other embodiments, the distance between the wet curtain 4 and the electric heating element 3 is 10 mm to 45 mm, and may be, for example, 20mm, 25mm, 30mm, 40 mm. The inventor of the present invention found through research that an excessively large distance between the wet curtain 4 and the electric heating member 3 may increase the size of the entire humidifier, which may affect compactness, an excessively small distance between the wet curtain 4 and the electric heating member 3 may cause water and steam of the wet curtain 4 to easily affect the electric heating member 3, which may cause short-circuit and other problems, which may affect the service life of the humidifier, and scale may easily adhere to the electric heating member 3, which may affect the heating efficiency and the service life of the electric heating member 3.
