How to confirm that the air filter is new

Hello, in this case, you need to remove the air filter to take a look, the old and the new are still easy to distinguish.

Hello, if the air filter is new, there are no impurities and no dust in it, and the old one can be seen at a glance.

Generally speaking, if the air filter is new, there should be no color change, or there is dust in it to be detected.

The filter is clean, free of skin lesions and dirt; The inside and outside of the filter are clean and oil-free; There is no loosening at the end of the installed filter.

Hello, this is generally to open and check whether the air filter is clean and the production date to judge the old and new.

Hello, this one is very simple, open the engine compartment cover, take the air cleaner card away, and see if the air cleaner is new?

Hello, the new air filter is relatively clean and free of dirt and dust, and the old air filter will be black.

This is very simple, as long as it is not unpacked, it is generally a new product, there is no big doubt, and it is difficult to confirm it when it is installed in the car.

Hello! In this case, open the air filter cover directly and check the cleanliness of the air filter.

Hello, this one is very simple, open it directly to see if the size is new, the old one will have dust.

This is easy to determine, the new air filter is free of a little dust and impurities, you can refer to it.

Hello, the question you said is very simple, open the hood, take out the air filter, and the new one is not dirty at all.

Hello, if you have this question, you can take out the air filter to see that the new air filter has no impurities at all.

If you can see it, look at his filter.

It is clear whether the filter needs to be replaced. Depending on the use environment and frequency of use, if there are any of the following situations, it is necessary to consider replacing them. A sign that the HEPA filter needs to be replaced.

1: The air volume of the air outlet is significantly smaller, and the noise is significantly larger.

2: The color of the HEPA filter becomes very black.

3: The purifier has a peculiar smell.

What you need to pay attention to when replacing the filter.

1: Don't believe that a 10-year HEPA filter can be used.

HEPA filters that last up to 10 years may exist, but they are not used in air purifiers, but in the clean rooms of industrial plants. So why can this HEPA filter be used for 10 years, because in front of this HEPA that can be used for 10 years, there are 5 or 6 primary, medium-efficiency, and sub-high-efficiency filters in front of it to help it filter relatively large dust particles, and this 10-year filter only filters the tiniest and most difficult dust in the last pass. Just like the battlefield, through the sacrifice of countless small soldiers, the survival of the general was finally preserved.

If there is only one general at the beginning, he may be knocked out as soon as he plays.

2: Don't be reluctant to replace.

As a consumable, it is not recommended to leave the HEPA filter unreplaced for a long time, and it is best not to clean or clean it. It's not because I'm a businessman and I go against my will for profit. I'll use a disgusting analogy, the HEPA filter is actually the same as a paper towel, when you finish wiping your mouth, I don't recommend you to brush it with a brush, or wash it and keep it tomorrow before continuing to wipe your mouth.

The same goes for HEPA filters, which not only help you absorb dust, but also all kinds of bacteria during use. When you feel a pity, vacuuming can only remove some inconsequential large dust, and bacteria and small particles cannot be removed.

In fact, if you think about the reason for buying an air purifier, it is either that there are children at home, or pregnant women, or the elderly, or the sick. The role of air purifiers is to prevent these susceptible people from being harmed by the disease. Although it costs money to buy medicine, it reduces the pain of the suffering of loved ones.

When buying, buying a big brand is also the most worry-free, for example, the British IAM can guarantee that it will be replaced directly without repairing it if it is broken within a year, which is where it is convenient to choose a big brand.

Just look at it. Visually inspect the air purifier's filter when it is dirty, and it is time to clean or replace it.

Some air purifiers will be designed with a barometer to indicate that when the filter is too dirty, dirty to a certain extent, the wind resistance of the filter itself becomes larger, and the air pressure difference is too large, and the air purifier will alarm itself to prompt the user to clean or replace the filter.

It is recommended to find the instruction manual that came with the air purifier to see the instructions on changing or cleaning the filter.

In recent years, with the increasing air quality, installing a room purifier has become the first choice. Although many people regard the air purifier as a "panacea", thinking that they only need to turn it on once to "cure the disease", but they don't know that the filter in the purifier also needs to be replaced in time, otherwise it is likely to breed mold, bring secondary pollution, and become a hidden "poison" in the home!

At the beginning of the operation of the purifier, there was still a basis for "curing the disease", because the dirt in the air would be automatically adsorbed to the filter. However, when the filter is saturated, it will produce secondary pollution, and the adsorbed viruses, bacteria, and particles will be re-blown into the indoor air through the fan, which is not the hidden "poison" in the room?

Therefore, the filter in the purifier must be replaced in time, but when should it be replaced? How do I replace it? It has become a common problem for everyone.

Today, we have taken stock of the things that should be paid attention to when replacing the filter screen of the purifier:

1.Most air purifiers come with a filter replacement light, and when the filter indicator light is on, it means that the filter needs to be replaced. However, many air purifiers' filter lights can't detect these conditions, depending on the actual situation.

2.When the user feels that the purification effect is not obvious, it is time to replace the adsorption or filter material, which is usually best done once a year. If the contamination is heavy, it should be replaced every 3 to 6 months.

In addition, if the filter material turns black after turning off the purifier and power supply, it also means that it needs to be replaced.

3.The front filter of the air purifier can be washed with clean water, and after cleaning, it needs to be spun or blown dry before being installed in the air purifier, and you can also use a rag or vacuum cleaner to remove dust.

4.However, if you don't want to change the filter frequently, but you are worried that the filter purifier will release "poison" if you don't replace the filter purifier, use an air purifier with a photocatalytic principle that does not rely on the filter, and uses the national core patented technology --- photocatalytic purification module, completely decomposes formaldehyde, bacteria and viruses and other harmful substances, and is effective for a long time without secondary pollution!

Because I make car filters, I know! The air filter of the automobile is roughly divided into PP and PU and environmental protection, which are more common. The air filter of PP and PU materials is simple from the outside, and the good air filter paper is relatively neat, the stiffness of the paper is relatively high, and there is no pungent smell.

Don't listen to the repairman, and don't think that the quality of the air filter depends on the fold of the paper, because the density of the filter paper does not represent the accuracy of the filtration.

The air filter is not good, mainly depending on the following three aspects:

1) Air filter waterproof performance: As we all know, the air contains a lot of moisture, especially in rainy days, the water content in the air will be higher, once the air filter waterproof performance is not good, the air filter is easy to get wet, once the air filter is damp, it will affect the air machine to suction unimpeded, or even blocked, customers will pay for the high electricity bill.

2) Air filter filtration accuracy: If the filtration accuracy is not high, a little finer dust impurities will be sucked into the air compressor in large quantities, thus affecting the service life of oil, oil, oil filter, bearing, etc.

First of all, look at the weight of a good air filter, and then a good air filter is relatively dense and does fine work.

You can check the operating status of the engine If the air cleaner is dirty, it will not take enough air, resulting in insufficient fuel burn.

The car's air cleaner is installed in front of the carburetor or intake pipe and is used to filter the air entering the engine. In general, the role of the air filter is to finely filter the air entering the engine cylinder, inhale dust, and ensure that the engine air intake is clean.

There is a lot of dust suspended in the air, the main component is silica, which is a harder substance than metal, if there is no air filter filter, the engine will inhale a lot of air containing dust and particles, resulting in serious wear and tear of the engine gas. You can check the surface color of the air filter, if the dust on the surface of the air filter is cleaned, the filter paper is still gray and black, which means that the filter paper can no longer be tried and should be replaced immediately.

The role of an automotive air filter

1. Make the air conditioner lattice close to the shell to ensure that the unfiltered air will not enter the cabin.

2. Separate the dust, pollen, abrasive particles and other solid miscellaneous rocks in the air.

3. Adsorption of water, soot, ozone, odor, carbon oxides, SO2, CO2, etc. in the air; It has a strong and withered long-lasting water adsorption.

4. Make the car glass not covered with water vapor, make the driver and passengers have a clear line of sight, and drive safely; It can provide fresh air to the driver's cabin, avoid the driver and passengers from inhaling harmful gases, and ensure driving safety; It can effectively sterilize and deodorize.

5. Ensure that the air in the driving and passenger compartment is clean and does not breed bacteria, and create a healthy environment; It can effectively separate solid impurities such as dust, core powder, and abrasive particles in the air; It can effectively intercept pollen and ensure that the driver and passengers will not have allergic reactions and affect driving safety.

Hello, it is a pleasure to serve you and provide you with the following answer: Air purifiers usually identify the filter by the model of the filter. Causes of the problem:

1.Incorrect filter model: Some filter models are incorrect, which may cause the air purifier to not recognize the filter correctly, which may affect the normal operation of the air purifier.

2.Poor quality of filters: Some filters are of poor quality and may cause the air purifier to not properly identify the filter, which can affect the proper functioning of the air purifier.

Workaround:1Check the model of the filter element:

Check that the filter is of the correct model and if not, the correct filter should be replaced. 2.Replace the filter cartridge with a better quality:

If the quality of the filter is poor, the better quality filter should be replaced to ensure that the air purifier is working properly. Personal Tips:1

Replace the filter element regularly: Replace the filter element regularly to ensure that the air purifier is working properly. 2.

Use the right filter: Use the right filter to make sure your air purifier is working properly. 3.

Use a better quality filter: Use a better quality filter to ensure that your air purifier is working properly.

1.Master the characteristics of paper filters and how to clean them.

These cartridges are made of microporous filter paper with a treated surface. When the engine is working, the air filters out the dust through the micropores, ensuring that clean air enters the cylinder. During use, a layer of dust will adhere around the filter element, and no water or oil should be used when cleaning to prevent oil and water from contaminating the filter element.

There are two commonly used cleaning methods: Tap method, that is, take the filter element out of the shell, gently pat the end face of the paper filter element to make the dust fall off, and do not knock on the outer surface of the filter element to prevent damage to the filter element. Purging method, that is, using compressed air to blow from the inside of the filter element to the outside to blow the dust away.

To prevent damage to the filter paper, the compressed air pressure must not be exceeded.

2.Clean and replace the filter cartridge regularly.

In use, the air filter element should be cleaned frequently according to the car maintenance regulations, so as to avoid increasing the air intake resistance, reducing engine power and increasing fuel consumption due to excessive dust adhering to the filter element. If the filter element is damaged, it should be replaced in time.

3.Properly installed to prevent air from entering the cylinder without filtration.

When inspecting and maintaining your air filter, the gasket on the filter must be properly installed. If the gasket has been aged, deformed or broken, it should be replaced with a new one.

4.When replacing a new filter element, you should choose the original ** filter element, and do not use an inferior filter element.
