I live in the southernmost tip of Northeast China, where haze is produced by inland heating in winter and spring. It is well known that haze is very harmful to people, and the most fundamental culprit is MP2.5 (particles with aerodynamic equivalent diameter less than 2.5 microns). Aerosols composed of dust and dust in the air will cause irreversible harm to the lungs of healthy people. My Xiaoxin air conditioning filter life has expired, if beyond the replacement cycle, air conditioning filter absorption of a large number of impurities will lose the filtering effect, leading to bacterial growth, reproduction, seriously affecting the health of the occupants in the car, so I made an appointment with the store to replace the original factory anti-PM2.5 air conditioning filter, especially now is the end of the epidemic, should be more responsible for their own and family health.
First, the small file of the car owner:
Ika ID: meteor shower
Car series: 2013 Skoda Xin Rui
Age: 7 years
Mileage: 126000 km
Maintenance items: replace the filter element of the original factory air conditioner
II. Maintenance process
Very familiar with it, often receive my after-sales brother, in helping me register vehicle information.
Xiao Xin opened the station and maintained that everything was ready.
This is Skoda original accessories PM2.5 efficient purification of air conditioning filter elements, the use of high-performance PM2.5 non-woven cloth plus activated carbon composite filter materials, while increasing the PM2.5 particles have a higher capture efficiency of meltblown electrostatic materials, can quickly and effectively intercept pollen, dust, soot and other suspended respirable substances, purify the air inside the car from the source, can ensure that the air inside the car is clean and fresh.
If you look at the details again, the packing is still very good.
After opening the box, you can see the air filter element with certificate, instruction manual and sealed package.
Open the manual, you can see the content is very detailed, each step has instructions, the key point is to open the vehicle co-driver’s locker, remove the baffle, you can find the air conditioning filter element to replace.
This is the front of the air conditioner filter element.
This is the reverse side of the air conditioner filter element.
Look at the details again, because this air conditioner filter element uses PM2.5 non-woven cloth plus activated carbon composite filter material, while adding melt-blown electrostatic materials with higher capture efficiency of PM2.5 particles, and effectively intercept suspended respirable substances such as pollen, dust, soot, etc., the quality is still reassuring.
The replacement of air conditioner filter element has officially begun.
This is the replacement of the old air-conditioning filter element, you can see that the surface is very rough, filled with a variety of dust, soot, pollen and other suspended respirable substances, close to can smell the pungent smell.
Comparing the new and old PM2.5 filter elements for efficient purification of air conditioners, we can see that the old air conditioning filter elements have been deformed, and the shape is loose, the color is yellow and dark, while the new air conditioning filter elements are very clean and tidy.
The master in charge of maintenance pressed the new air conditioner filter element very quickly.
Practice is the best test method, so I brought a professional MP2.5 detector, this instrument is very sensitive, I will use it today to see how effective this air conditioner filter element is.
First open the internal circulation, the effect of filtration in the case of high temperature, you can see that the pollution value shows 3, which proves that the air in the car is very good.
Then turn on the external circulation of the air conditioner and measure the air quality in the car under the condition of low temperature and low temperature. you can see that the pollution value shows 6, and the air quality does not change much. We should know that most of our air pollution in the north is more than 60 or even hundreds of centres. it shows that the effect of this air conditioner filter element is very good.
Finally, let’s settle the fee. The air conditioner filter element includes a total of 128 yuan per hour.
III. Summary
After changing the air conditioner filter element, the air inside the car becomes much better, and the fishy smell before it also disappears. Under normal circumstances, the air conditioner filter element in the car should be replaced every half a year, and it can also be determined according to the external environment of the driving. If the environment is relatively humid, or if the haze is high, the replacement cycle can be shortened appropriately. Now the weather is getting warmer, windy, gray and willow catkins are floating, and haze visits from time to time, the air filter element is easy to clog, so how to distinguish the need to replace the air filter element? In fact, when we remove the dust from the air filter paper, we use a soft brush to remove the dust from the surface of the filter element along the crease direction, and gently tap the end face of the filter element to make the dust fall off. When the dust on the outer surface of the filter element is removed, the true color of the filter paper no longer appears, or the inner surface of the filter paper is dark, then the filter element must be replaced. This is also my little experience to share with you. I hope it can be helpful to you.
