The reason why there is no music when the airx air purifier is turned on is that the filter needs to be replaced. My Aipinsheng air purifier will also give a voice prompt when changing the filter.

Jadeli air purifier, the timer button and automatic button flash when it is turned on, and there is an alarm. What is going on? I think you'd better read the manual. If the power-on timer and automatic button are flashing, and there is an alarm sound, check the manual. If you don't know, it's best to ask customer service. You can ask my air purifier sales customer service.

Electrostatic electret filter technology:

Using non-woven fabrics loaded with electrostatic electrets to collect dust is an upgraded version of HEPA technology. The advantages are low wind resistance, high efficiency, high dust holding capacity, and most importantly, safety. Represented by the "high-efficiency electrostatic air filter" on the market, it uses a breakthrough filter material that carries permanent static electricity.

Effectively blocks particulate pollutants larger than 0.1 microns in the air, such as dust, dander, pollen, bacteria, etc., while ultra-low impedance ensures energy saving. In addition, the deep dust-holding design ensures a longer service life. As of 2013, it has been widely used in home and vehicle air conditioners (such as best-selling models of well-known brands such as SAIC, Volkswagen, and General Motors) as well as in some commercial construction fields (such as the Bird's Nest, Beijing Hotel, and Capital Airport Phase III).
