Air conditioning air filters play a vital role in industrial production and daily life. Especially today, when the issue of environmental protection has attracted much attention, maintaining the air conditioning filter system not only helps to improve environmental quality, but also provides a healthier indoor environment for employees and families. Therefore, it is particularly important to understand and regularly maintain the air conditioning filter. 

 I. The harm of dirty air conditioning filters 

 1. Affect the heating effect 

 Too much ash accumulation in the filter will lead to a significant decrease in the heating effect of the air conditioner indoor unit. This is because the accumulation of dust will hinder the effective heat exchange between the evaporator and the indoor air. The room circulation slows down, and the indoor temperature cannot be evenly distributed. 

 2. Increase power consumption 

 When the indoor temperature cannot reach the set value, the air conditioner needs to extend the operating time to make up for the temperature difference, resulting in a significant increase in power consumption. 

 3. Risk of water leakage 

 The dirty filter may cause dust to adhere to the surface of the evaporator through cracks and flow into the water tray with condensed water. Over time, the water tray may be blocked, which will cause the problem of water leakage in the indoor unit. 

 4. Health risks 

 Long-term uncleaned filters will become a breeding ground for dust particles, germs and odors. These pollutants will spread into the air when the air conditioner is running, irritating the eyes, nose and other mucous membranes, and even causing respiratory diseases or skin allergies. 

 II. How to clean the air conditioning filter correctly? 

 In order to ensure the efficient operation of air conditioning and indoor air quality, we need to maintain the air conditioning filter regularly. The following are the specific cleaning steps and precautions: 

 1. Regular cleaning 

 The primary and medium-effective air conditioning filters should be cleaned at least once a month. If there is a lot of dust in the environment, it is recommended to shorten the cleaning cycle. If necessary, the filter should be replaced in time to avoid affecting performance due to aging or damage. 

 2. Cleaning steps 

 • Wash the filter with warm water below 40 degrees to avoid deformation caused by high temperature. 

 • If the filter is dirty, neutral detergent can be used for decontamination treatment; if the pollution is light, it can be washed directly with water. 

 • After cleaning, be sure to dry it completely before installing it back into the air conditioning unit. 

 3. Correct installation 

 When installing the filter, you should pay attention to the positive and negative direction of air flow and operate in strict accordance with the requirements of the equipment manual to avoid affecting the use effect due to installation errors. 

 III. Summary and Suggestions 

 By regularly cleaning and maintaining the air conditioning filters, we can achieve the following goals: 

 • Improve the cooling and heating effect of air conditioners and reduce energy waste. 

 • Avoid the leakage problem caused by the blockage of the water tray and extend the service life of the equipment. 

 • Improve indoor air quality and protect the health of families and employees. 

 In short, keeping the air conditioning filter clean is not only responsible for the equipment, but also a double commitment to the environment and health.
