What is the effect for people who bought sterilization air conditioners?

I have bought an air conditioner for Haier's sterilization cabin, mainly for the elderly and children at home. Living in Beijing needs to pay attention to air quality, otherwise it is easy to get sick. Haier's sterilization air conditioner can achieve triple sterilization, self-cleaning and cold expansion sterilization, and the whole air supply system such as evaporator, air duct and air outlet can achieve high temperature sterilization at 56℃. In addition, it can also eliminate harmful substances in the air. Old people and children used to cough a lot, but now they don't cough.
