Is the disinfection card useful or not?

Sterilization efficiency of sterilization card is very low. There are many restrictions on the use environment, duration, effective dose and other conditions. In order to play a better "sterilization" performance, it is necessary to use more sterilization cards in a closed small environment for a long time. A single disinfection card can not play an efficient disinfection role in an open space. Safety: It is most important to wear something irritating to children for a long time. Many parents may think that this non-contact disinfection method is safe, but it is not. May irritate eyes and respiratory tract; Chlorine dioxide has a pungent smell similar to chlorine gas, and if it is exposed to high concentration (>: 500ppm) for a long time, it will make people feel uncomfortable. If you directly inhale the gas released by the sterilization card, it may cause irritation to the nasal cavity, respiratory tract, throat and eyes, leading to tears and cough.
