The results showed that 88% of air-conditioning fins exceeded the standard, and 84% of air conditioners cooled. The total number of moldy molds exceeded the standard; the bacteria detected in the air-conditioning fins exceeded the standard by up to 1000 times.
Air conditioning pollution brings turbidity of the breathing air, and the pollution of the washing machine also threatens human health. The results of the washing machine survey in Beijing showed that the total number of bacteria detected by the washing machine reached 13,692/ml in the sampling of 100 fully automatic pulsator washing machines in Beijing. With reference to the standards of public health places in China, the pollution situation of washing machines has far exceeded the relevant requirements of the total number of bacteria should not exceed 300 / 25cm2.

They believe that only the effect of “decontamination†is clean. I don’t know that this kind of home cleaning is wrong. The secondary pollution of home appliances is serious. The focus of deep cleaning is on "decontamination" and "sterilization" simultaneous processing, in order to completely kill the pathogens in the heat sink.
