Air conditioning ducts are seriously polluted

Heat sink for all kinds of bacteria

According to experts, at present, citizens often have little knowledge of air-conditioning pollution. At present, most households usually only stay at the filter level for cleaning air conditioners. In fact, this does not completely eliminate the pollution caused by air conditioners. Because the filter only filters a portion of the dust, some of the dust still accumulates on the heat sink through the filter. In addition, the heat sink of the air conditioner is a place for cold and heat exchange, and it is in a damp state for a long time, and is suitable for breeding various bacteria.

The air conditioner contains secret bacteria such as mold, Staphylococcus aureus and Bacillus cereus, and the total amount of bacteria above is as high as 160,000/cm2. In China, 88% of the total number of air-conditioning fins exceeds the standard, and the average number of detected bacteria exceeds the standard by nearly 40 times, and the most serious exceeds the standard by nearly 100 times. If you do not clean, turn on the air conditioner, just blow the bacteria out, and stand at the air outlet of the air conditioner, bacteria can easily enter the eyes and respiratory tract at once, it is easy to form conjunctivitis, respiratory diseases, or allergies.

Regular cleaning and disinfecting air conditioner heat sink

Every year, the air conditioner should be thoroughly cleaned and disinfected before the first season of the season change. However, in the frequent use of air conditioners, such as summer, people may stay in the air-conditioned room for a long time, and the indoor air quality directly affects our health. The air conditioner needs to be cleaned regularly. The simple method is to disinfect the air conditioner once a month.

The air-conditioning heat sink is not removable, and due to its special structure, it is useless to wipe it with a damp cloth, clean the brush, etc., and it is easy to damage the heat sink. In this regard, the disinfection air-conditioning heat sink should use a regular air-conditioning disinfectant, which can be easily done by yourself. At the same time, the selection of products requires the "National Ministry of Health disinfection product certificate number", so that the sterilization effect is guaranteed. The dirt and germs on the heat sink are removed, and the air conditioning and cooling effect will be better.
