20mm 2.4mhz piezoelectric humidifier, energy conversion plate

From the shop's description

This Piezoelectric Humidifier is made of high-quality material, durable, anti-corrosion, anti-aging, and high hardness, great effect, and serve you for a long time. With electronic high-frequency oscillation ( 2.4MHz), the liquid water molecules are processed into flowing mist and release a large number of negative ions, which react with smoke, dust, and the like floating in the air to cause precipitation. It also can effectively remove harmful substances such as formaldehyde, carbon monoxide, and bacteria, so that the air can be purified and the disease can be reduced, keep your and your family’s health. Low impedance, waveform is stable, high electromechanical conversion efficiency and low dielectric loss, this atomizer saves more energy than heated atomization. Suitable for industry, warehousing, family, hotel, and so on. Features: Made From High-Quality Materials. Electronic High-Frequency Oscillations. It also can effectively remove harmful substances such as formaldehyde, carbon monoxide and bacteria.
