What to pay attention to when choosing a humidifier.aromatherapy diffuser

　　1、 To select the appropriate category

　　The main products sold in the market include ultrasonic humidifiers, evaporative humidifiers, and composite humidifiers. Ultrasonic humidifiers have the characteristics of low noise, small size, low power consumption, and low price, but have high requirements for water quality. Although evaporative humidifiers do not have high water quality requirements, due to the need for a large air volume, they usually use a larger body and require regular replacement of the filter element, resulting in higher power and noise than ultrasonic humidifiers. Composite humidifiers use two or more of the above humidification methods simultaneously to achieve humidification functions. Consumers should carefully understand the product type and humidification principle when purchasing, and make choices based on their own needs.

　　2、 Pay attention to whether there are water quality requirements

　　Some humidifiers have water quality requirements when used. If ordinary tap water is used, it is easy to produce white powder and scale. It is recommended that consumers try to use pure or distilled water as much as possible. Attention should also be paid to regularly cleaning the humidifier. If the water stored in the humidifier is stored for a long time, it is particularly easy to breed bacteria, which can cause respiratory diseases.

　　3、 Choose a trustworthy brand

　　There are many brands of humidifiers on the market, with prices ranging from tens to thousands of yuan. It is recommended that consumers try to purchase humidifiers from reputable large supermarkets or e-commerce enterprises that are produced by legitimate manufacturers. They should pay attention to checking whether the product identification is complete and whether the humidification capacity, power, noise and other indicators of the product are clearly marked. At present, there is no clear "three guarantees" policy for humidifiers in China. Consumers should inquire about the warranty period of the product from the merchant when purchasing, and request * and warranty vouchers.
