How to clean the central air conditioning filter?

After the central air conditioner is used for a period of time, a large amount of dust and dirt will accumulate on the filter, evaporator and air supply system, and a large number of bacteria and viruses will be generated. These harmful substances circulate indoors with the air, pollute the air, spread diseases, and seriously endanger human health.

The dirt will reduce the cooling efficiency of the air conditioner, increase energy consumption, and shorten the service life of the air conditioner. Therefore, the air conditioner must be cleaned after being used for a period of time or when it is shut down during the season. Only in this way can you have a healthy and clean air environment.

1. First remove the dust filter according to the instructions. When disassembling, be careful not to touch the metal part of the indoor unit to prevent it from being scratched.

2. After removing the air filter, lightly pat it or use an electric vacuum cleaner to remove dust. If the dust filter has too much dust, it can be rinsed with water or a soft brush dipped in neutral detergent, but the water temperature should not exceed 50 ℃ during cleaning. Do not use washing powder, detergent, gasoline, banana water, etc., to avoid deformation of the filter . In addition, do not use a sponge to clean, otherwise it will damage the surface of the dust filter.

3. After rinsing it with clean water, wipe it dry with a soft cloth or dry it in a cool place. Never expose it to the sun or dry it in an open flame such as a stove to avoid deformation of the dust filter.

4. When cleaning the panel, wipe gently with a soft cloth dipped in warm water or neutral detergent, and then wipe it dry with a dry soft cloth.
