[Actual test] Only 1 degree of electric hammer air purifier in 5 days: a powerful energy-saving small cyclone

On November 7, Luo Yonghao and his Smartisan officially started their crosstalk show in Chengdu. In addition to launching the new Nut Pro 2 mobile phone as scheduled, they also released a livelihood product, the "Changxi" smart air purifier.

At the press conference, Mr. Luo showed his ambition driven by passion for the new air purifier product that has joined the Hammer family.

"We rush in and make top-notch products. When the price is good, those giants will be devastated."

"If we can accelerate our pace and become one of the best brands in this field, the future will be easier."

Since the beginning of history, Mr. Luo has always been very loud and generous in praising his own products. Now let's take a look at the "tone" of this "Free Breathing" air purifier and whether it is worthy of Luo Yonghao's strong praise for it?

1. Unboxing

The product logo and product name are on the front and back of the Changhuxi packaging box, and product labels are symmetrically affixed to the left and right sides. The product information is displayed concisely, clearly and fully, in line with Hammer's consistent cool color style.

The packaging adopts a tape-free sealing design. After cutting the packing tape, the entire box can be lifted and opened.

Foam boards are placed at the four corners of the box to prevent shaking and collision during transportation. The main body of the machine is equipped with a pure white protective cover to prevent dust when it is idle.

Due to the weight of 17KG and the size of one person wide and half a person high, if a girl wants to lift it vertically, it will still take some effort.

It must be said that the overall minimalist Nordic style of Changhuxi is undoubtedly more friendly than other products that claim to be "cool and colorful" but bring light pollution troubles to users. In addition, its pure white color is easier to integrate into the modern home environment and will not look abrupt and eye-catching in any room.

At the top front of the breathable body, there are four modes: extreme speed, sleep, automatic, and manual, as well as six indicator lights for filter replacement and child lock, and a physical button for mode switching.
The back is the power button and WiFi function button. There is also a small black dot above the power button. You may ask, what is this for? In fact, this is a light sensor. Changhuxi can automatically adjust the display brightness according to the brightness of the surrounding environment, similar to the automatic screen brightness adjustment function on our mobile phones.

There is a display screen on the front that can display the PM2.5 value in the room in real time. In order to be more intuitive, the display screen uses three display color segments to represent different air quality levels.

On the back of the product is a PM2.5 sensor vent. Unlike other general products, the Changhuxi uses a laser to detect PM2.5, which ensures accuracy. Because of the improved monitoring accuracy, it is best to clean it with a cotton swab after using it for a period of time to avoid affecting the monitoring accuracy.

There are handles on the left and right sides of the body of the Changxi, plus four casters at the bottom, so even a soft girl can move it at will. After actual operation, these four casters are not only silent, but also smooth as silk.

2. Open the fuselage and look inside

The back cover of the Free Breathing adopts a magnetic fit, and there is a clean and neat "click" sound when the cover is closed.

Inside the machine, there are activated carbon compartment, motor compartment and standard filter compartment at the top, middle and bottom. The small compartments of the activated carbon compartment are designed to prevent the super activated carbon filter element for removing formaldehyde from shaking in the compartment.

The motor compartment is equipped with Hammer's silent weapon, a large-sized DC brushless motor. The large size does not require a very high speed to obtain a large air volume, which can reduce noise to a certain extent.

You will be presented with the relevant tests shortly.

The standard filter compartment at the bottom of the fuselage provides layered protection for the filter, in addition to the dust net. The dust net is a 60-mesh PET ultra-fine dust filter, which is used to block particles with a diameter of 60 mesh (0.3 micrograms/cubic meter), hair, pet dander and dust, etc., and there is also an anti-slip bottom groove at the bottom.

The contact part between the filter element and the motor compartment also adopts a sponge sealing layer, which effectively improves the sealing and purification efficiency.

As for air purifier, as the name suggests, purification ability is the first indicator.

The Changxi filter element uses a three-layer composite filter. Each layer plays a different role. Together, they filter out harmful impurities in the air to ensure your family's healthy breathing every second.

The first layer: 60 mesh PET filter, which blocks particles with a diameter of more than 60 mesh (0.3 mm), hair, pet dander, dust and other larger pollutants that are even visible to the naked eye;

The second layer: H13-level high-efficiency HEPA filter. The H13-level standard means that it can filter PM 0.3 impurities that are even smaller than PM 2.5, and can effectively filter pollen, allergens, secondhand smoke, etc. Compared with the mainstream H10 and H11 level filters on the market, the H13 level has a purification efficiency that is 14.97% and 4.97% higher than them respectively;

The third layer: high-quality activated carbon filter, with a granular activated carbon content of 1.1 kg, mainly targets formaldehyde pollutants that are common in Chinese families. When Chinese families decorate their new homes, formaldehyde is difficult to avoid due to the decorative materials, and formaldehyde is one of the main causes of leukemia.

3. It’s time to open the APP and start using it

Download the "Chang Huo Xi" APP on your mobile phone and log in to your Huanxi Cloud account. If you are using a Hammer phone like me and have logged in to your Huanxi Cloud account on this phone, you can authorize the login to the "Chang Huo Xi" APP with one click.

After making all the preparations, press the WiFi switch and follow the connection process to connect the Changhuxi air purifier to the WiFi hotspot at home. From now on, as long as you have a network, you can remotely monitor and control it as you wish. You can monitor the indoor air quality, temperature, and humidity in real time on your mobile phone, and you can also adjust the purifier mode. Click the upper right corner to view the weather forecast simultaneously.

As the first APP of Changhuxi, it is relatively simple in terms of function, and its purpose is also very straightforward to tell you that it is an APP for air purifiers, which is for air purifiers. It's just that it has a Hammer Mall attached, and Mr. Luo still has some tricks up his sleeve.

It is believed that this APP can also add a timing function in the future, as well as reminders when indoor pollution exceeds the limit.

4. Start the test

1. Replace the filter element (remember to slide to unlock)

When replacing the standard filter element: hold the handle on the top of the rear cover to remove the rear cover, slide the filter element knob to the far left, remove the dust filter and then remove the lower standard filter element to complete the disassembly. When installing, just reverse the above steps.

Slide to unlock is here! 3, 2, 1 to unlock!

When replacing the additional filter element: squeeze the switches on both sides to open the upper additional filter element hatch and take out the upper additional filter element to complete the removal. For installation, reverse the above steps.

The price of the filter element of the Changhuxi air conditioner is rising as the purification index is ranked first. According to the official website of Hammer, the price of the standard filter element of Changhuxi air conditioner is as high as 799 yuan. However, the enhanced filter of Xiaomi's formaldehyde removal is only 169 yuan.

From the perspective of later use costs, the benchmark for Hammer Free Breathing is obviously high-end air purifier products like Sweden's BlueAir, not Xiaomi. After all, purification efficiency is a fact in front of us.

We simulated a 9-square-meter bedroom environment and used cigarettes to simulate the pollution source. In the automatic and high-speed modes, we tested the purification efficiency and noise within 30 seconds with 30 seconds as a timing point;

2. Air purification efficiency

In automatic mode, a dramatic scene occurred during the entire test process. The purification efficiency was even higher than that in high-speed mode, and the maximum noise emitted was even lower than the noise when typing on the keyboard.

In sleep mode, the purifier is always working quietly, but the purification efficiency has made concessions to noise reduction, and it takes four minutes to absorb the pollutants into the capsule. Its noise value is controlled lower than that of a desktop computer host when it is running.

In general, the purification efficiency of "Free Breathing" is still very good. It can absorb pollution into the capsule in a very short time, and the noise control is completely in line with the effect claimed by Mr. Luo at the press conference.
3. Power consumption test

According to actual tests, the daily power consumption is 0.2 kWh. Judging from the above test results, the Changhuxi purifier is still a benchmark for energy saving!

Can the "Breathe Freely" in automatic mode also have a slogan: "Only one kilowatt-hour of electricity in five days"? It can purify the air efficiently without wasting electricity.

As the first generation product of Smartisan's entry into the field of smart air purification, Changhuxi not only reflects the unique style of Smartisan as a "design company" in terms of design, but also reflects Smartisan's determination and confidence in aiming at the high-end in this field in terms of performance.

In today's context where sentiment can no longer make a living, Mr. Luo has stopped talking about sentiment and turned to people's livelihood projects, shouldering social responsibilities. I believe that the Hammer's ecosystem will be established soon to provide better services for our lives.

Back to the product itself, if you also want to enjoy the comfort of breathing freely in silence, you might as well buy one and enjoy the fresh air. Although the price of 3499 yuan is not cheap, compared with foreign brands with the same effect and the price of nearly 10,000 yuan, it still reflects the advantages of Chinese manufacturing. In addition, if you regard it as a family health investment, Hammer's free breathing air purifier is still worth the money.
