Introduction

"Haze" has made Shijiazhuang, an inconspicuous city, a hot search list. The number of pm2.5 has broken 1000, factories have stopped working, schools have closed, and various jokes about haze have added a helpless "topic" to the quiet city. However, it was too late for other provinces to gloat. Half of China's territory, including Beijing, was shrouded in haze. This incident not only made the country more determined to fight against haze, but also led to the hot sales of air purifiers and anti haze masks.

Although there are many kinds of air purifiers, can they meet our requirements? As users, the air purifier we are looking forward to is nothing more than haze removal, PM2.5 removal, large air volume, silence, intelligence, etc. Today, we bring an air purifier-352 x80 air purifier that Mr. Luo has said is good. Interestingly, why is the manufacturer called "325"? It means that three times, five times, two times, Now let's see if it can really have an immediate effect on the air!

Unpacking

The 352 X80 air purifier is packed in double layers. The first layer is a brown corrugated box. Thick packaging can protect the product, while the second layer is a white box. In addition to the product name, there is an actual appearance diagram. The net weight of the product is 18KG, so it is relatively heavy overall, but fortunately there are two openings on the outer package for lifting. The package includes one host, three filter elements, four casters, one power cord, one remote control, instructions and warranty card.

appearance

The 325 X80 air purifier has only one color appearance, which can be improved. It is a cuboid with two ends design, which matches the modern home style very well. The top is a UFO test air quality indicator light. Two section design, the upper part is gray and the lower part is off white. The product has no water chestnut, and the shell is also made of plastic, so it is more suitable for families with children at home.

In order to facilitate the user and protect the product, the touch screen is protected with white stickers, and some important instructions are printed on it. In fact, the important tip is to read the manual carefully. However, this 325 X80 air purifier is relatively simple to operate, and can be operated roughly once or without looking.

Tear off the sticker and you can see the touch screen on the top. The high transparent PMMA acrylic control panel of Mitsubishi and the 5-inch TFT color screen make this product reveal a high style in its simple style.

details

Now let's analyze this product a little bit, because the details are the key to evaluate the quality of the product. First, the upper layer. The edges and corners of the acrylic plate are chamfered, which not only looks beautiful, but also increases the safety factor. The rear part has a groove shape, which should be used to place items. After all, this purifier covers a large area.

There are seven buttons, namely, air volume, mode, timing, light, child lock, filter element and switch key, as well as a display screen. There is no physical button on the body, and the functionality of the touch button is relatively comprehensive. This is between the height of the product, and the child lock function seems to be of little use.

The acrylic plate on the top has the touch of tempered glass, but if tempered glass is used, the weight will definitely increase.

The workmanship between the panel and the lower end is very meticulous. Each side of the 325 X80 air purifier adopts a 90 ° arc design, which reflects the safety concept in every detail. Unlike a purifier that the author tried before, the four corners are edges and corners and are metal shells.

One side of the product is an air quality inspection port, and there is a flip cover with holes outside for protection. The sensor is an original Japanese product, which can accurately feel the change of external air quality. The air inspection port worth noting is far away from the exhaust outlet, ensuring the accuracy of air measurement.

There is a "handle" on the other side, but it is actually the switch of the filter element. The interior is designed with magnetic adsorption+snap, but with a little force, the outer box can be opened, and the internal filter element can be seen in front of you.

filter element

It can be seen that the upper part of the shell is magnetically adsorbed, while the lower part is designed with a buckle. The filter element of the 325 X80 air purifier is very unique. It adopts a drawer type design, with a four layer filter screen structure. Each layer is marked with its name and function, and the middle part also has the replacement and opening methods of the purifier.

It can be seen that every "small drawer" has a small handle. In order to reduce unnecessary space, the handle is designed very short. The filter screen is in the shape of a drawer, which is very simple to replace. Moreover, the filter screen has a large area and is not replaced so frequently.

Because the fan is at the bottom, and then we introduce the filter screen from the bottom up. First is the primary filter screen, which can effectively absorb large plush. Moreover, the primary filter screen can be cleaned with water, which can protect the next few filters, and is economical.

Then there is the medium efficiency air filter, which aims at the larger particles in the air, such as pollen, dust, etc.

Then there is the efficient odor filter. This filter element is filled with 1300g activated carbon particles, and the shape of the honeycomb improves the ventilation and contact area. This filter screen can not only purify the odor in the air, but also remove harmful gases such as formaldehyde. The last step is the high-efficiency air purification filter screen. The final haze removal efficiency can reach more than 99.5%, which is very powerful.

assemble

To introduce the external products and details, let's assemble and use them. The four wheels are very practical and well done. The outside is gray, and the inside is gray engineering plastic. The logo can be seen on the front. Two wheels have buckles that can be locked to fix the purifier.

The socket of the power supply is very unique. It is placed at the bottom. The advantage is that it does not affect the appearance, but the disadvantage is that it is not conducive to waterproof. In addition, this purifier itself is very heavy. If you plug it in for the first time, you still have to turn it down to find the socket.

use

After the wheels are installed and the power is connected, our 352 X80 air purifier can be used. This purifier does not join the ranks of wifi smart home, but is set through touch panel+remote control, which includes power supply, light, mode (automatic rapid sleep) and air volume regulation. It can be seen that there is a small concave groove above the purifier, which can be used to place the remote control.

The rotation of 352 X80 air purifier is dominated by large air volume, which can reach 120 240 360 500 610 760 m3/h of different air volume through remote control or panel, and is suitable for different environments and room sizes.

In order to more objectively verify the air volume of this product, each purifier has passed the manual test. Under a certain temperature and pressure, the calibrated air volume and measured air volume of each mode are marked. However, it should be noted that with the increase of time, the ventilation area of the filter element will decrease, and the corresponding air volume will also decrease, which is normal.

The light of the air purifier is usually used to display the air quality, and the 352 X80 air purifier is no exception. It can be divided into green, orange and red. Green is definitely good air, while orange is average, and orange is pollution. The lighting effect of this product is quite conspicuous, which can be used as the backlight at night.

How to display the condition of the filter element? Through the filter element button on the panel, you can see the status of the filter element on the left and whether it needs to be replaced. Of course, there is also a timing button. If you don't want to open it overnight, you can set the time. When the set time arrives, it can be automatically closed.

effect

After a period of use, let's check the use effect of this air purifier. First, PM2.5. We use 360 Air Master and 720 Enviro Bora for comprehensive calibration.

Fortunately, the pm2.5 in Shijiazhuang can break the 1000 mark, resulting in the indoor pm2.5 value exceeding 500, reaching 506. The test environment is a 30m3 room, and the air volume is 360. One minute later, pm2.5 is reduced to less than 100, and 30 minutes later, pm2.5 is maintained to less than 10. Because the environment is not airtight enough (the living room is connected to the bedroom), the effect may not be particularly good, but it will have a better effect for rooms with good airtightness.

Many purifiers are placed in the bedroom, so we will measure the noise at the air outlet through the 720 environmental report:

Wind noise (dB)

Environment 30

120m³/h    35    

240m³/h    38    

360m³/h    49    

500m³/h    59    

610m³/h    64    

760m³/h    69    

summary

The appearance of this 352 X80 air purifier is very suitable for modern household style. The operation and filter element replacement are also relatively simple. The detailed design also considers the situation of having children at home. Although the weight is heavy, the universal wheel at the bottom makes up for the weight problem, and the design of the power socket at the bottom also prevents the baby from getting electric shock.

In terms of haze removal and noise, the 352 X80 air purifier also performs well in addition to its good performance. The haze removal effect is rapid. The noise is general under high air volume, and there is almost no noise in sleep mode.

In this era of haze, for your baby, you really need such a purifier to protect the health of your family.
