1. Appearance design: simple lines are more hale and hearty

In the just-concluded 2017 Q1 Zhongguancun Online ZDC data survey, the trend of the air purifier market is somewhat different from that of previous years. More and more users pay more attention to product performance and user experience rather than product price when purchasing purifiers. This is also why high-end air purification products above 5000 yuan have more than 1/3 of the attention. The object of the author's evaluation today is such a high-end air purifier-Agiesen T02.

Different from the products evaluated by the author in the past, the first impression of this purifier is "calm". In addition to the champagne gold color that highlights the temperament, the all-aluminum alloy body also adds a lot of points to it. Whether it is home or business occasions, it can be easily integrated into the indoor environment, not abrupt.

In today's serious product homogeneity, the purifier market is no exception, the same product shape makes people have no desire to buy. Agiesen T02 can be described as a "clear stream" in the industry. Different from the rounded appearance of most products, Agiesen's designers use seemingly simple lines to outline it somewhat hale and hearty. After starting up, the top display screen is full of scientific and technological sense. The 360 perfectly symmetrical top air outlet makes me believe that Agiesen's designer must be a science student with rigorous thinking.

The top display is like the center console of a car. The display content is quite rich. From air quality, temperature and humidity, operating mode, air quality indicator, everything you can think of about high-end air purifiers can be found in this small screen. The display screen adopts touch control design, and various functions can be realized with one key, which is very convenient for operation and screen cleaning. Provide 0-8 hours timing, the user is more convenient to use; Timing key long press 3 seconds to activate the child lock, to avoid the risk of accidental touch of children at home.

Tap the power button on the top, and the purifier will run in smart mode after a "ding" sound, and the display will light up at the same time. In order to avoid "light pollution" when used at night, it can be adjusted to sleep mode, which can turn off all lights except the "sleep" indicator, and the wind speed is automatically adjusted to the mute gear, which will not affect the user's noise.

In addition to the touch of the top display screen, this purifier also has two other more convenient control methods: mobile phone WeChat APP control and remote control. Triple intelligent control, fully meet the needs of different users.

The author has always been full of curiosity about the screen that can display all kinds of data. In my eyes, this is the most intuitive representative of science and technology. This small display screen brings me this feeling. It can display the indoor temperature, humidity and PM2.5 concentration in real time, and it is quiet with a smell of black technology.

All this is inseparable from the high-precision sensors located on the side of the machine to monitor the indoor air in real time, and the monitoring data is reflected on the display in various forms of different colors of light and numbers.

2. The air volume easily breaks thousands, how does it do it?

The particulate matter CADR of this product reaches 750 m3/h, with an applicable area of 52.5-90 ㎡, and it only takes 17 minutes to purify a 90 ㎡ living room at a time. Formaldehyde CADR also reaches 225 m3/h, the newly decorated room contains a large amount of formaldehyde, benzene and other strong carcinogens, and the release period is quite long, if there is no strong purification, it is difficult to remove it.

The reason why it has such a high CADR value, first of all due to its surrounding air intake, top of the wind design. There is an air inlet around the product, and the air outlet with symmetrical design at the top can reach a maximum air volume of 1260 m3/h.

Good design is on the one hand, internal materials are also very important. Open the filter door on the back to see the barrel-shaped high-density ATP antimicrobial peptide HEPA composite filter inside. The primary layer is mainly responsible for intercepting large particles of dust and hair in the air. The high-density ATP-HEPA antimicrobial peptide layer adsorbs and filters pollutants such as PM2.5 and allergens such as pollen and dust mites in the air. The innermost layer is a high-efficiency activated carbon layer, which adsorbs indoor gaseous pollutants such as formaldehyde, benzene and TVOC. Triple filtration makes the air completely clean.

As for the installation of the filter screen, there was also a small episode in the process of the author's evaluation. When I first opened it, I tried my best and failed to start it. Finally, I found that the problem was in the buckle of the filter screen. Since the bottom buckle cannot be locked after the filter screen is installed, the protection mechanism inside the purifier is triggered, and the normal start can not be started until the buckle is locked again.

Of course, in order to achieve ultra-high CADR values, the above two factors are necessary but not all. The internal core fan and air duct design is a crucial part. Agiersen T02 uses the top Japanese Shipu motor. In the author's previous article "How much do you know about the purifier motor?", the motor of the air purifier has been explained in detail. For further information, please refer to this article.

When it comes to turbocharging, I believe that friends who like cars will not be unfamiliar. The main function of this technology is to increase the air intake of the car engine, thereby increasing the power and torque. Simply put, it is to make the car more "powerful". When this technology is applied to the air duct design of the purifier by the designer, it also has unexpected effects. The 360 ° turbocharged air duct inside Agisen T02 can effectively increase the air intake, and the effect on the air volume is quite obvious.

3. Wind speed noise test: the result is satisfactory

Wind speed is the most intuitive embodiment of air purifier CADR, and noise is one of the most critical factors affecting user experience. Therefore, in the evaluation process, the author tested and recorded the wind speed and indoor noise of the air outlet under each gear, and the results are as follows:

Wind speed test results

Air speed of the first gear air outlet:	Second gear air outlet wind speed:	Third gear air outlet wind speed:	Speed gear air outlet wind speed:

The design of the 360-degree air outlet at the top makes a great contribution to the improvement of air volume. Even in the first gear, the wind speed of the air outlet reaches 2.18 m/s, and the speed gear reaches 6.58 m/s. In the second and third gears, the wind speed at the air outlet is 4.47 m/s and 5.37 m/s respectively. It can be seen that there is still a certain gap in the wind speed between the gears, allows users to select gear according to their own needs.

Noise test

Since the indoor cannot achieve absolute silence, the author first tested the indoor noise value when the purifier was not turned on, and tested the indoor noise under each gear in turn, and the records are as follows:

Indoor noise when the purifier is not turned on:	Indoor noise in 1st gear:	Third gear indoor noise:	Indoor noise in speed gear

When the purifier is not turned on, the indoor noise is 38.9dB; This purifier is better than I expected in terms of operating noise control. The first environmental noise is only 41.1dB, and you can hardly feel it unless you are in an extremely quiet room. The ambient noise in the highest gear is only 54.4dB, which is basically equivalent to the operating sound of a household vacuum cleaner. At this time, the air output is very large, therefore, most users will not open in this gear for too long.

Editorial Comments

When it comes to "high-end", what do you think of at the first time? Is it a high price or a lot of flashy functions? I don't know when it started, the word "high-end" has a trace of irony, which may be the result of the impetuous development of the market.

This Agiesen T02 air purifier redefines the meaning of high-end for us: not only the shape must be tough and temperament, but more importantly, the strong performance and excellent user experience. Whether it is the appearance design, purification effect or the test results of air volume and noise, this purifier is worthy of the word "high-end!
