The smell of food, cigarette smoke, unpleasant odors from the sewage system, allergies are just a small part of the reasons why you should buy a device for cleaning the air in the house. There are many different air cleaners and filters for air purification. You can choose simple or inexpensive models. The professional purifiers have high efficiency, but they also cost very much.
Today we have review of air purifier called Xiaomi Air Purifier 2s. It is improved version of Xiaomi Air Purifier 2, and the main difference is in OLED display in the new model. So, let’s start with unboxing, and then talk about specifications and main features.
Xiaomi Air Purifier 2s: Unboxing
Xiaomi Air Purifier 2s comes in a quite large box (60x30x30 cm), but not heavy ー about 6 kg. Inside the box you can find an air purifier with a filter, power cable and user manual in Chinese.
Xiaomi Air Purifier 2s: Design
Xiaomi Air Purifier 2s has a stylish and well-recognizable design. The similar design is used in a portable Xiaomi Mi AI Speaker. The white body is made of plastic with an original perforation on all sides, which plays the role of ventilation grill through which air is drawn.
Xiaomi Air Purifier 2s is pretty big device. It has dimensions of 50x24x24 cm, and it weighs about 5 kg. The manufacturer positions it as a floor-standing device, but you can also place it on the curbstone, bedside table or any other elevation.
Xiaomi Air Purifier 2s: Functions
Xiaomi Air Purifier 2s has a large size, because it provides high air purification performance. The larger the filter size, the more air to pass through the air purifier at a time. As you can see from the image above, the filter takes more than half of its internal space. It allows to clean up to 310 cubic meters of air per hour.
The filter has a cylindrical shape. It is needed to capture air from 360 degrees. By the way, it is one of the main differences between Xiaomi Air Purifier and other models.
The filter has a three-layer construction. The outer layer is a grid that catches large particles. This layer is protective for the second layer, which is a HEPA H11 filter. This is a very important layer. It catches the smallest particles, 0.015-0.3 μm in size, which pass through the first layer. It is very effective for filtering allergens, microbes, fine dust particles, mold spores and infections. Finally, the third layer – activated carbon. It perfectly absorbs unpleasant odors and, in general, is an excellent adsorbent. This filter design allows 99.99% of PM 2.5 particles to be retained, as well as to clean the air of unpleasant odors.
The purified air, passed through the filters, is directed upwards by two powerful fans in the upper part of the air cleaner. They create two spiral airflows, which ensures the necessary efficiency of air exchange.
Xiaomi Air Purifier 2s: OLED Display
The main feature of Xiaomi Air Purifier 2s from other Xiaomi Air Purifiers is OLED display. It shows PM 2.5 index in real time, the temperature, humidity, and operating mode.
If you want, the display can be turned off with the button on the rear panel. But, to be honest, I do not see much sense in this. The image on OLED screen looks like a simple inscription. It does not light much and does not irritate the eyes in the dark. In addition, the brightness of the screen is adjusted automatically depending on the ambient light. There is an ambient light sensor located next to the power button.
Xiaomi Air Purifier 2s: Modes
Xiaomi Air Purifier 2s has three modes. The auto mode provides automatic regulation of fan rotation speed, depending on the air pollution. If the pollution is low – under PM 2.5 index, the fans run at low speed, and purifier works very silent. If the index of pollution above PM2.5, the fan speed increases for faster airflow through the filter.
The second mode is night. In this mode, the fan is almost noiseless, depending on air pollution.
Finally, the third mode is user mode. The user chooses the speed of fan rotation.
How does Xiaomi Air Purifier 2s count the PM 2.5 index? It uses a laser sensor, which counts the number of particles in the cleaned air stream. The particle sensor has a removable structure, which is very important in terms of care of the air purifier.
Xiaomi Air Purifier 2s: Control
Xiaomi Air Purifier 2s can be controlled either via buttons on the body or via Mi Home app.
Mi Home allows you to turn the air purifier on and off, select the mode, monitor PM 2.5 index, temperature, humidity, etc. Also, when you are away from home, you can create convenient schedules and scenarios, so other family members will always have clean air.
How to add Xiaomi Air Purifier 2s?
It is very simple. After installation and authorization in Mi Home application, you need to connect to the Wi-Fi of air purifier.
Then launch Mi Home and find a new device.
I was asked to choose the room where the air purifier was installed, after which I was able to fully control it from the app or from a convenient widget on the main screen.
Please note: the name of the air purifier and widget is in Chinese, but you can change it in English or any other language.
The app settings allow to turn off the display of Xiaomi Air Purifier 2s. Also, you can turned off the sounds. However, the most useful function is the schedule. You can add the on and off time, as well as the frequency.
Xiaomi Air Purifier 2s: Filter
The main thing of any air purifier is the filter. Fortunately, it is very simple to change the filter on Xiaomi Air Purifier 2s. You need to change it every 3-6 months, depending on the air pollution. The filter costs about $49.99. You do not have to remember when to change the filter. Mi Home app will say you when you need to do this.
From time to time you need to wipe the sensor of solid particles. You don’t need any special tools, just use cotton swab to wipe the sensors.
Xiaomi Air Purifier 2s: Price
Yes, Xiaomi Air Purifier 2s is not a cheap device, but if you seriously think about what you breathe, then I highly recommend this air purifier. Thanks to the circular air grip and the dual silent fan, it provides high performance. The beautiful OLED screen allows you to see air purity, temperature and humidity in real time.
Also I want to note the option to control Xiaomi Air Purifier 2s over the Internet. You can clean the air in an apartment or a country house, even if you are thousands of miles away.
