With the rapid development of economy, the development of industry is even faster. However, with the massive development of industry, there are more and more industrial waste gases. Although the country has repeatedly dealt with them, for reasons such as employment, there is no condition for highly polluting enterprises to completely control them. With the rapid development of the automobile industry, the price of cars is becoming more and more affordable, and people can also afford cars. The increase of cars has led to the continuous increase of exhaust emissions. With the increase of various detection methods, people's fear of PM2.5 has become increasingly serious.

In this situation, various power plant manufacturers have launched their own purifier products. Most of the purifiers are large in size, and are basically used in large rooms or homes. Haier desktop air purifier can be said to be a product born in time, mainly for the desktop, which can be conveniently used in offices or computer desks, It is no longer necessary to worry about someone smoking, nor dare not open the window all day long because of fear of dust.

Haier has printed the product appearance, product model and QR code information on the front of the outer package. The overall color is brushed metal, which looks more elegant.

On the side of the package is information about the barcode of the product and transportation precautions.

The outer package of the product is designed with a handle, which is very convenient for users to carry.

Open the outer package, the internal design of the product uses customized plastic foam packaging, and the top groove is placed with the switching power supply for Haier desktop purifier.

The product is placed in the customized plastic foam as a whole, which is tightly fixed, so that the safety is very good for transportation or self carrying, and it is not easy to cause product damage during transportation or carrying.

All contents of desktop purifier include packing list, instructions, purifier host and one switching power supply for power supply.

The desktop purifier is powered by a wide voltage input, DC12V/1A switching power supply, with a maximum total power of only 12W, which is similar to the maximum power consumption of the current intelligent router. Therefore, Haier's desktop purifier is relatively power efficient.

Haier's logo is on the front of the side of Haier's desktop purifier, while the air inlet is directly below it. It can be seen that the air inlet is designed to be quite dense, which can effectively ensure the intake of air to ensure the purification effect.

The side rear of the product is the power input port and USB output port.

However, it is a pity for the author that although this USB output power supply port can charge mobile phones and digital devices, its maximum output is only 500mA. For current mobile phones or other digital devices, this charging current is slightly insufficient, resulting in a significant reduction in the actual utilization rate of this output port. Under the condition of normal switching power supply, The author will not choose to use it for charging, because the charging current is too small.

The specific parameters of the product are given at the bottom of the purifier. It can be seen that the desktop purifier can only purify 15 cubic meters of air per hour, so it is more suitable for personal use next to the computer desk. If the family uses it normally, it is recommended to purchase Haier's larger air purifier. The power of the whole machine is only 8W. It runs for 24 hours and consumes one kilowatt hour of electricity in five days. Therefore, the power consumption of Haier's desktop air purifier can be ignored if it is used for ten hours every day at the desk or in front of the computer. It is very energy-saving. In terms of noise, the maximum noise is only 50dB. At low speed, the noise is very small. Even at high speed, the noise is acceptable. Therefore, it is very powerful for office use. The overall weight is less than 1Kg, which is very light.

Haier tabletop purifier has been equipped with a filter screen when it leaves the factory and placed inside the machine. The filter screen is very convenient for disassembly and assembly. On the side printed with Haier's logo, at the lower air inlet, it can be easily opened by gently pressing down.

The arc-shaped air inlet ensures effective air intake and is equipped with a small filter element.

The filter element is designed to be directional and must be placed in the specified direction to achieve good results. The filter element provided by Haier is mainly used to filter PM2.5 and formaldehyde, PM2.5 The harm of formaldehyde is clear to everyone. Needless to say, the same formaldehyde has always been an inevitable pollution for everyone. Both offices and homes, home paint, etc. are places where formaldehyde volatilizes. Therefore, Haier tabletop purifier can make users easier to breathe fresh air and effectively avoid various diseases caused by air because it is placed on the desktop.

A small aromatherapy box is placed at the bottom of the filter screen, which is very practical for users who like the fragrance at home. It can easily pour the essence into the box, and then fill their home or office with the fragrance they like through the air purifier. However, for the author's family, this function is basically useless, Some people in my family are sensitive to fragrance, so this function will not be repeated this time. But for users who like the fragrance of roses or lavender at home, this function is undoubtedly very commendable.

What is placed in the filter screen is a composite filter material. As for the filter material used in the filter screen, we can not know too much. In order to obtain the best purification effect, it is appropriate to purchase the filter screen provided by the original factory. Therefore, if the time is long, it is the best choice to purchase the matching filter screen from Haier.

After power on, all the indicators on the top of Haier will light up and go out automatically after 3s. At this time, only the key lights will light up. By default, Haier's air purifier will turn on the low-speed mode. The four status indicators of the desktop air purifier are designed with capacitive touch, which can achieve high-speed, medium speed, low-speed and switch on and off by touching the icon. Also, by pressing and holding the key, you can switch between multiple modes, such as ultra high speed operation, light off mode, etc. Ultra high speed is suitable for indoor smoking, which can be quickly purified. The light off mode is suitable for sleeping and rest, which can be selected according to personal needs.

Haier desktop air purifier also provides a very romantic function, that is, the romantic light mode, which is very suitable for young couples or lovers with emotional appeal to create some small romances. It displays red, orange, yellow, green, cyan, purple in turn. The color is very beautiful. Here, the author photographed three colors under the romantic light mode to show the romantic mode. It can be seen from the figure that, Very warm and romantic color change.

In terms of air purification, because there is no PM2.5 testing instrument on hand, it is difficult to visually display the specific changes of PM2.5. However, from the test results of the author on various wind speeds, under the ultra-high wind speed, basically one person can smoke near the purifier to meet the purification needs, but if three or four people smoke in the office, The purification effect is not particularly obvious. However, for people near the purifier, the purification effect is OK. From the original intention of the design of the desktop air purifier, it should be used by one or two people at their desks or computers. From this perspective, Haier's desktop air purifier is very powerful. Since the filter screen of the air purifier belongs to consumables, the author searched the Haier Mall and mainly wanted to confirm the price of the filter screen. However, the author regretted that the official website of Haier Mall did not provide the purchase connection of filter screen consumables, and hoped to add them as soon as possible.
