20 13, smog has become the key word, and many big cities are shrouded in smog. The visual impairment caused by aerosol system composed of dust, sulfuric acid and other particles in the air is called smog. Long-term inhalation of smog will cause damage to the body and even lead to death. In 20 15, Chai Jing's Under the Sky was born, which aroused heated discussion among Chinese people and people began to pay more attention to air quality. Maybe we can't make a documentary that affects Chinese people like Under the Sky, but we can do it ourselves, advocate environmental protection and make some contributions to the blue sky.
The outside world is wonderful, and the outside world is foggy. Although it is funny, it is true. Faced with the deterioration of air quality, I can wear a mask when I go out, but we can't work indoors. At this time, we need an air purifier to purify the air around us. There are so many air purifiers on the market that it is difficult for you to buy them. Today, Bian Xiao will bring you this mini air purifier-Yosemite intelligent negative ion physiotherapy instrument.
First of all, I would like to thank the it 168 testers for their free product testing.
Unpacking experience
The outer packaging of Yosemite intelligent negative ion physiotherapy instrument adopts the design of heaven and earth closing cover, with considerable damping, white rectangular appearance and a sad and beautiful logo pattern in the middle.
The parameters and manufacturer information of Yosemite intelligent negative ion physiotherapy instrument are listed on the back, and the corresponding signs are in English.
Open the box, all the family members of Yosemite intelligent negative ion physiotherapy instrument are there, a statement, a cotton swab, a charger and an air purifier. Yosemite air purifier has two models, one is black Bluetooth model, the other is white wifi model, and Bian Xiao got the white wifi model.

Yosemite intelligent negative ion physiotherapy instrument is cylindrical in shape, so pay attention to the surrounding environment when placing it. If you accidentally hit it, it will easily fall. Although there is an annular anti-slip pad at the bottom, the center of gravity of the product is not at the bottom, so you should pay attention to the placement position.
The bottom is surrounded by an inlet for purifying air. Turn the arrow to open the bottom. There is a washable cotton core in it, which is mainly used to filter particles in the air. There is also a metal filter element, which is optional. This metal filter element is not available in this product experience.
Yosemite's intelligent negative ion physiotherapy instrument supports hand-held breathing mode, and the exterior also has anti-slip design. Using ABS fireproof material, it is durable and just right to hold, and the weight of 290g will not be heavy. But individuals still don't like to breathe hand in hand, because Yosemite's intelligent negative ion physiotherapy instrument needs real-time power supply to work. Although it supports mobile power supply, it is not very convenient to use because it has an extra cable, so it can be used as a desktop.
There is a power interface and an air volume control key on the back, and the maximum air volume can be adjusted in 2 gears. Yosemite intelligent negative ion physiotherapy instrument adopts 3050 turbofan, and the noise is less than 30db, which is equivalent to the rustling of leaves when rubbing.
What needs to be mentioned here is that there is a motor in the air purifier, which mainly drives the air volume. But if the quality of this motor is poor, it will be noisy to use. Many purifiers in the market use ordinary motors, which will produce various noises after a period of use, seriously affecting the quality of life.
There are two buttons on the front, one is the power-on button and the other is the mode selection button. In addition to the power button, the power button also has the function of turning off the lights. This is mainly used at night. If the light is too bright to affect sleep, you can press the power button to turn off the light, but the equipment is still working. Yosemite intelligent negative ion physiotherapy instrument has two working modes, one is air purification mode (blue) and the other is breathing mode (green).
The top of Yosemite's intelligent negative ion physiotherapy instrument adopts a dull shape, where the exhaust fan of the fan exhausts air, and negative ions are generated by two carbon brushes at the front end.
In fact, negative ions are generated by negative ion generators. After the negative ion generator is connected with voltage, it is rectified and filtered with special electronic materials to obtain pure DC negative high voltage. The DC negative high voltage is connected to the release tip (carbon brush) made of metal or carbon, and a large number of electrons (e-) are released by the DC high voltage at the tip, and the electrons (e-) will combine with oxygen molecules (o2) in the air to form negative oxygen ion O3.
Product experience
Yosemite intelligent negative ion physiotherapy instrument supports mobile power supply, and it is also very convenient to connect power supply. Directly pressing the power button above will display a green light, so you can enter the breathing mode. At first, there was some peculiar smell, mainly the smell of new products, but it wouldn't last for a while. Hand-held breathing mode can directly aim the air outlet at the nose. Personally, I feel very comfortable after using it these days and I like the taste very much. I feel refreshed after breathing.
The white version of Yosemite Intelligent Negative Ion Physiotherapy Instrument supports remote control of app, but there is no QR code scanning and download address of app in the manual. You need to pay attention to the official account of WeChat, and then download the app inside. Do you think this will work? No, the app software downloaded by micro-signal could not be connected to this product, and it could not be connected after repeated attempts, so I called customer service and they sent a software link internally before connecting to this product.
Because Yosemite's intelligent negative ion physiotherapy instrument is connected through wifi, it is necessary to bind the wifi account and password at home to connect the device and surf the Internet. Here, I still hope that there is a clear app download address in the software manual, which is convenient for users to use.
When the device is connected to wifi, it can be controlled by mobile phone. There is nothing special about mode adjustment. Mainly user-defined interface. This function is mainly to set a time, just like an alarm clock, which can control when Yosemite intelligent negative ion physiotherapy instrument is turned on and control the air volume.
Products need to be maintained and cleaned after long-term use. A cotton swab can be used to wipe the steel needle at the top. Because it is easy to oxidize when exposed to air, it needs to be cleaned regularly.
Effect test
After being used indoors for a period of time, you can find some dust on the edge by opening the cotton core at the bottom. These are still used indoors. If you put them in the car, I believe there will be more dust, but this seaweed can really stop some dust.
Do a little experiment here. Prepare a sealed box and lay a layer of tin foil inside the box.
Light mosquito-repellent incense dripping with wax (which can produce a lot of smoke) and put it in a box.
Set the air purifier prepared in advance to purification mode, then quickly put it into it and seal the cover. As can be seen from the picture, there is already smoke rolling inside.
Five minutes later, I opened the box and found that the smoke inside had dispersed. What's more amazing is that I didn't smell the smell of mosquitoes choking my nose. It is very effective in purifying the air.
Green breathing mode, breathing mode releases pure small particle size negative ions, which is beneficial to skin, respiratory system and blood.
Blue is the air purification mode, and the purification mode releases compound ions, which has stronger sterilization effect. Look, there are two tiny bright spots in the picture, which are the state that two steel needles are electrified. Maybe you will have questions. What's the difference between this and the carbon brush in front? In fact, the steel needle also releases negative ions, but the steel needle releases composite ions and negative ions, while the carbon brush releases pure composite ions. So don't touch the steel needle and carbon brush at ordinary times, it will pollute.
Summary and suggestions
After using Yosemite's intelligent negative ion physiotherapy instrument for a while, I got some understanding. First of all, it is quite powerful in purification mode and breathing mode. Personally, I also like to breathe this fresh air after rain. However, the product is still a bit flawed, such as unstable app software and simple functions. If the app can have other rich functions, I believe it will be more interesting for users to use. It may be better if a humidifier function can be added, but this may be more than this price, so this air purifier with a price of 399 yuan is still worth picking up. After all, many air purifiers with the same price have no two modes to choose from, and the fan noise is well handled.
Attached to the base map, the sky is still blue and beautiful. After all, the improvement of air quality is fundamental. (The author of this article comes from the IT 168 elite test group)
