How to clean the fan blades of the Xiaomi air purifier

Since Xiaomi officially released the air purifier on December 9, 2014, the ** price of its filter cartridge is 149. And the air purification itself is only 899 yuan, many people think that Xiaomi's filter element is expensive, now, let's take a look at the price and adsorption capacity of the Xiaomi filter.

The Xiaomi air purifier I bought in September last year has been used for 4 months. However, since the end of December, the mobile app has been pushing messages to remind me to replace the filter element. Compared with the popular concept of changing every six months, Xiaomi's prompt seems to be a bit early.

So the author is ready to take it apart and wash it, after all, a filter cartridge of 149 yuan is not cheap.

The picture shows the filter cartridge after 4 months of use by Xiaomi.

As can be seen from the picture, the original green filter element filter membrane is already a little dark blue.

After half an hour of cleaning and wiping, it can be seen that the filter element has changed from the original dark blue to light blue.

When I opened the lid from the top of the empty purifier, I found that there was a lot of dust accumulated on the fan blades inside.

Comparison before and after the smog in Hangzhou's West Lake.

Because the author temporarily lives in the West Lake District of Hangzhou, where "there is heaven above, and Suzhou and Hangzhou below", the scenery of the West Lake is indeed beautiful, and there is a sense of quiet life that makes people calm down and walk birds and read books every day. However, in recent years, Hangzhou has also started a yellow warning for smog, and the air quality is gradually not as good as before. That's why the 4-month-old air purifier has become like this.

I heard that even Shenzhen has haze this year, and the air filter in the north should be used for less than half a year, right? I put my favorite filter back on, and the mobile app was not pushed, and it should continue to be used for a month or two.

The Xiaomi air purifier is cleaned like this:

1. The dust removal filter or dust collection plate in the air purifier should be cleaned frequently, generally once a week, and the foam plastic or plate should be cleaned and dried with soap before use, so as to maintain smooth airflow and hygiene.

2. When there is a lot of dust on the fan and electrode, it should be removed, and it should be maintained once every six months. You can use a long-bristled brush to remove dust from each electrode and wind blade.

3. Clean the air quality sensor every 2 months to ensure that the purifier is running at peak performance. If the purifier is used in a dusty environment, clean it frequently.

What the air purifier cleans

The core component of an air purifier is the filter layer, and the air purifier filters produced by various manufacturers generally have three or four layers.

The first layer is the pre-filter, which is made of different materials by each brand, but its function is the same, mainly to remove dust and hair with large particles.

The second layer is a high-efficiency HEPA filter, which mainly filters allergens in the air such as mite debris, pollen, etc., and can filter inhalable particles with a diameter of microns to 20 microns.

This layer of filters filters out the particles that consumers are generally concerned about today. The service life of this layer of filter is generally a few years. If the filter is full of dust and particles after a long period of use, there is a high chance that these accumulations will blow into the air again with the air.

A good air purifier can effectively remove dust, pet dander and other particles in the air that we can't see with the naked eye, and can also remove harmful gases such as formaldehyde, benzene, second-hand smoke in the air, as well as bacteria, viruses and other microorganisms in the air.

The device under the button on the back of the Xiaomi air purifier is a sensor, which is mainly used to monitor the content of the current ambient air.

The bin cover can be opened to easily remove dust and other impurities, and a vacuum cleaner can be used to absorb dust during cleaning.

If it can't be cleaned, you can use a vacuum cleaner to remove dust from the primary filter screen.

Clean the door, filter, and impeller with clean water and let dry.

Assemble the cleaned filter back into the purifier and install it back into the purifier hatch at the same time, then start the test, and reset the filter if the filter is replaced.

The above are the steps to clean Xiaomi Air Purifier 2, I hope it will help you.

The filter cartridge of the Xiaomi air purifier is usually not reusable. Generally, the filter cartridge is replaced as a whole in 3-6 months according to the usage. Air purifier filters have a lifespan.

When the air purifier is turned on, the service life of the filter in the purifier is displayed. Filters that have exceeded their useful life can no longer be used and need to be replaced. How to choose the three filters of Xiaomi air purifier?

HEPA Net Dust Holding Capacity Comparison (Particle CCM) There are two main factors that affect the CCM of particulate matter. The first one is the size of the filter. The larger the extension area of the filter, the higher the dust holding capacity of the filter.

The second is the filtration level (material). High-grade HEPA filters tend to have a higher dust-holding capacity. The area of the three filter elements is compared with the HEPA mesh When the HEPA mesh grade of the Xiaomi filter element is H11, the only difference is the area.

The area of the filter is not difficult to calculate. Use a ruler to measure the height (width) and thickness of the filter paper, and then count how many layers the filter paper has, and then multiply by the area. Conclusion of the thickness of the HEPA mesh for the three filter elements:

Economy and antimicrobial filters have a larger (slightly larger) expansion area. The larger the area of the HEPA mesh with the same properties, the higher the dust holding capacity and the longer the service life. Comparison of activated carbon load (formaldehyde CCM) At present, mainstream air purifiers rely on activated carbon adsorption to remove formaldehyde and benzene odor, and the cumulative purification amount of formaldehyde is proportional to the quality and filling amount of activated carbon.

There are two types of activated carbon used for purifiers on the market: traditional activated carbon and modified activated carbon, among which traditional activated carbon has a small adsorption capacity and is easy to saturate. The modified activated carbon has a large adsorption capacity and catalytic decomposition substances attached to the surface, which can prolong the adsorption life of activated carbon and improve the secondary pollution caused by the adsorption and shedding of activated carbon.

The width and density of the activated carbon mesh of the three filter elements of the three filter elements of Xiaomi all use modified activated carbon with high iodine value, which has good adsorption, but the amount of activated carbon filling is inconsistent. The weight of the activated carbon for the three cartridges has not yet been officially announced. We take apart the activated carbon filter cartridge of the three filter cartridges and weigh the net weight of the activated carbon filter cartridge.

Conclusion of activated carbon net weight: By weighing, it is not difficult to find that the activated carbon layer of the formaldehyde filter element uses more materials and weighs more, so it has a long service life. Conclusions and related suggestionsFrom the actual measurements, it can be seen that the dust holding capacity of the economic version and the antibacterial version is larger, while the activated carbon adsorption capacity of the formaldehyde removal filter element is larger and lasts longer.

In addition, the antibacterial filter adds an antibacterial coating to the HEPA filter, which is said to have an antibacterial rate of more than 99%, effectively blocking bacteria, mold, and dust mites.

It is generally recommended that the filter element be cleaned once or twice a month, and replaced in 3 to 5 months.

Filters that cannot be washed can be cleaned with a vacuum cleaner.

Filters are generally not recommended to be cleaned, and most filters can be cleaned, such as electrostatic precipitator filters. Generally, it is cleaned once or twice a month, and replaced once every 3 to 5 months of use to improve purification efficiency and avoid secondary pollution. If it is a washable filter, you can remove it and clean it with a soft brush in warm water to avoid the activated carbon in the filter.

When the substance is deformed at high temperature, it can also be added with medium-sized detergent, which can effectively remove pollutants, and it should be brushed clean and then dried when cleaning, or use a hair dryer.

Blow dry and put into an air purifier.

For the filter element that cannot be washed, you can use a vacuum cleaner or rag to clean up the dust, and we expose the filter element to the sun to help the filter element better desorb and remove dust, and maintain the purification effect of the air evolutionary.

Air cleaner. The polluted air is cleaned to the state required for production and life, that is, the air reaches a certain degree of cleanliness. Elements that are installed in filtration equipment to separate substances are used in a variety of applications depending on the material.

Metal filters, activated carbon filters, air filters, etc. Filtration. Air cleaner is also called air filter cartridge and air filter.

style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operation rooms and various precision operation rooms.

This question can be true, and the wise will see the wise. Theoretically, the filter element of the Xiaomi air purifier can be cleaned. Especially the outer floor.

However, manufacturers generally recommend that they should be replaced when a certain time limit is reached. In order to guarantee a better purification effect. However, if you use it in an area that is not serious, you can clean it up.

If you have any questions, you can consult the after-sales customer service.
