First let's find out what the air filter element does and what effect does it have?
The filter element is also called a filter, and there are usually two directly related to the owner. One is an air filter and the other is an air conditioning filter. So what does the air filter do? In fact, it is filtering impurities, and the ground gas is actually a mask of the engine. The effect is the same as that we usually wear masks, filtering particulate impurities in the air.
The air filter element mainly filters the air entering the engine. Now the air quality in our country is not very good, all kinds of smog and dust, if you do n’t have this air filter element, all the dust and everything will enter our engine. Some small dust may be relatively hard things. After a long time, it will run into the engine, piston, and cylinder. This will cause abnormal wear and tear of the cylinder, and even the oil will be dirty by impurities such as dust. Yes, maintenance should be done in advance.
The air filter has a great effect. If you do n’t look at it, it ’s like a piece of paper. Without it, it ’s equivalent to the engine running naked. It ’s like a person breathing deep in a sandstorm without a mask. This is very harmful. The air filter element will become dirty after a long time. This has a lot to do with our usual car environment. Some car air filter elements have run for 10,000 kilometers, and they still look clean, but some are dirty after only 5,000. No more.
Air filters have to be replaced after a long period of time. Sometimes they do maintenance. After-sales masters may say to you, "It's not too dirty, you can use it for a while after blowing it." Can you use it again? This is usable, but the effect will be worse, not worse than the new one.
After blowing, the air filter element has about half of the new effect. If it is used for a period of time, it will be about one-third of the new one. For example, the new one can be used for 3 months and can filter about 90% of dirty things. It can be used for one month and can filter about 40% of the dirt. If it is not a last resort, it can be replaced as much as possible. If it is dirty, it can be replaced with a new one. This is the best for the engine.
What does the air conditioning filter do? Is it OK to blow it?
If the air filter is the mask of the engine, then the air conditioning filter is the mask that the car puts on us after we sit in the car. It filters a lot more things, tiny particles, pollen, exhaust gas, bacteria, industrial dust, etc. In short, there are many. And now the better cars on the market come with PM2.5, which is good. If it is not replaced for a long time, it will lead to a strange smell in the air-conditioning air intake, which will cause nausea and nausea. At the same time, bacteria will increase and the human immune system will be harmed. Can the dirty air conditioner filter be used after blowing it? Of course you ca n’t, throw it away when you're done, there's nothing to say about it, let alone blow it, because blowing it won't help.
Sometimes we went to do maintenance. The air conditioner filter was originally replaced, but the master saw it was not dirty, then he blew it, and put it back in again. This is also one of the customary routines of after-sales, and the friends who go to after-sales maintenance must pay attention to it! Don't pay the money, but the maintenance is not done. It is recommended that the buddies who are not too dirty look at him to replace it, or ask to take away the old filter (including air conditioner and air filter) after maintenance, and just say that I want to take it home as a memorial, just to look like it, You can also guard against villains. Then go out and turn right into the trash can.
