With the development of the times, more and more families have bought a car, look at the streets coming and going, found that many drivers and passengers in the car when all wearing masks, especially in the face of the new coronavirus epidemic, which is particularly prevalent. Obviously the car has been very small space and ventilation, also wearing a mask, you do not feel comfortable? In view of this problem, I tried to find out why the Internet, the results found on the Internet a lot of brain-hole wide open netizens say to cold, sun protection, anti-racket and other irregularities may be caught, and for the author himself, more It may be in order “bacteria.”
In fact, I also have standing masks habit in the body, mainly due to He is the author mild “allergic rhinitis,” in case of season or as long as air pollution, etc., do not pay attention will be crazy sneezing and runny nose. However, “It is good”, each to a certain time, my nose has become the air filter “detector.” For people with allergic rhinitis, the nose is very sensitive, whether you are not a “allergic rhinitis”, as long as you’re the owner, for themselves and their family’s health, is the time to pay attention to the air filter the role of the. Note that air filter, air filter instead. The main role of the air filter, the air filter is pollen, dust, mist, carbon oxides and sulfides, to ensure clean air vehicle.
In recent years, haze serious problem, especially in the north than sand many areas, in order to prevent dust blown into the car, turn on the air as long as the car will go out, no matter how much dust outside, the air inside the car is very fresh, thanks to air-conditioning filter on the car. However, the air filter is a consumable to be replaced after a period of time, otherwise the accumulation of dust and debris above will not only affect the filtering effect, but also the breeding of bacteria, affecting their health, so the air conditioning filter regularly and replace the correct selection is required take seriously.
are now widely used on the market some pure air filter and activated carbon nonwoven fabric two materials, in contrast, the activated carbon of moisture and odor absorption features than pure nonwoven fabric. Secondly, for the past two years as people increase in PM2.5 air quality and degree of attention to the emergence of a HEPA air filter, the cartridge filter particulate matter is very good, can more effectively filter PM2.5. In addition, the air filter development so far, not only many kinds of filter, making the material more and more. Air filter based materials can be roughly classified into the following categories: a pure non-woven fabric, bamboo fiber, cold catalyst, activated carbon, nano-crystals and, Haiman Pu. In addition to pure bamboo fiber nonwoven fabric and two, the other materials are used to filter most of the HEPA filter in combination manner.
While appearing on the market a wide variety of air-conditioning filter material, but after screening the author found that most of its sales or activated carbon air filter. This is not surprising, as the popularity of the HEPA filter, activated carbon + HEPA filter combination of air-conditioning filter of the mainstream. The reason why activated carbon filter can become mainstream, mainly because of its terminal price increase is not much, and the filter haze effects are good, so popular with the favor of the major parts factory. Although cheaper than pure activated carbon filter cartridge nonwoven fabric more close, but now face a complex environment, not recommended, it can only filter dust, grit, and the like catkins particles larger than 5μm, to remove carbon and odor no significant effect . In addition to the above-mentioned commonly used non-woven fabric and activated carbon material, as well as the rest of the bamboo fiber, cold catalyst, nano mineral crystal, Haiman Pu although with stronger filtering effect, but in view of the individual factors as well as cost, currently in car It is not widely used on the air filter market.
While the above said so much, but in fact there some owners have such a concept, the role of air-conditioning filter is only tooFilter impurities in the air inside the car, so as not to pay attention to replace the air filter. For the purposes of cost savings, they tend to believe that as long as the filter fouling blown off above can become new continue to use, no need to be replaced. So really the case? In fact, this not only failed to get a clean, more likely to destroy the barrier filter dust powder.
Finally, it should be mentioned that, replaceable air filter for an cautious, air conditioning filter is generally installed in the front passenger glove box, internal organs need to toggle buckle replacement, after removing the glove box to remove and replace. Although there is no technical difficulty, but it is easy to try on their own to snap snapping, that time can only replace the entire glove box. So we do not recommend blind replaceable. Of course, you can also watch online tutorials, or to the 4S shop to ask professional staff, remember the removal and installation of the main points, then you can replace it yourself.

in addition to the need for regular replacement of air filter outside, regular cleaning of air conditioning systems also have the necessary. You can see from the above picture, automotive air conditioning system filters has two modes, but the air conditioning filter is placed in front of the evaporator filter, although the barrier is a lot of dust, but also tell you the truth, automotive air conditioning evaporator often most bacteria. I do not know if you have not found, in the summer open air, musty odor but the attendant! Want to know what the automotive air conditioning system to produce a musty odor of the real reason is not it? Simply put, the moisture is in the air conditioning system cooling through evaporation tank, causing the condensation of the evaporation tank to form a long-term wet mold, mildew in humid environments reproductive capacity is strong, musty odor which is the main reason for the outgoing air conditioning .
In addition to the air conditioner smelled musty odor than , sometimes accompanied by the owner who itchy rash embolismshape. This is also a kind of “air conditioning disease”, is mainly dust mites at work. Duct in an automobile, the sub-tank, the evaporation tank, a blower, all parts are likely to contact the air can breed dust mites. In fact, we can reduce or prevent the growth of bacteria in the air conditioning ducts, in addition to the need for regular cleaning of automobile air-conditioning system, usually the key lies in maintenance, how to make air conditioning ducts and keep in a dry state. I recommend the use of air conditioning, do not turn off all of this time only the function of air conditioning AC interface can be shut down, this way, while allowing the compressor stopped working, the fan continues to run for a few minutes to blow hot air after that, it dry and clean the air conditioning ducts, so that it can prevent the breeding of bacteria and mildew.
Currently, most vehicles are based on integrated heating and air conditioning systems, is simply a blower conditioning outside air suction intake duct, through the evaporation tank, the air filter after filtration, the outlet into the vehicle interior along the air flow passage through. Therefore, the air filter is like a car put on a mask, ensure fresh air inside the vehicle. If the air filter is not changed regularly and air conditioning system is not properly maintained, will make the radiator, the evaporator surface a lot of dirt accumulation, resulting in airflow blockage, which will make your air conditioning system in the cooling and heating effect is reduced, increasing the power consumption, noise phenomenon. Even more serious is the car smell but also endanger the health of the driver and passengers, it is easy if long-term in this environment induced respiratory disease.
