Xiaomiβs modern air purification systems have become the standard of quality in many homes and offices around the world, combining high filtration efficiency, low noise and a thoughtful design that fits into almost any interior. However, to make sure the appliances work as efficiently as possible and last for years, itβs important to understand how they work and adjust the basic parameters correctly.
In this article, we will take a look at how to use Xiaomiβs air purifier, from unpacking and initial installation to fine-tuning through a mobile app, how to change filters correctly, what modes of operation to use in different situations, and how to extend the life of the device without losing performance.
Proper operation is the key to clean air. Initial setup takes only a few minutes, but ignoring the basic rules can lead to rapid wear and tear. HEPA-Let's look at each step of interaction with the gadget in detail so that you can enjoy the perfect indoor atmosphere.
Initial installation and preparation for work
The process of familiarizing yourself with the device begins with its proper installation in the room. After unpacking, remove all transport films, including the protective layer from the filter itself, which is often inside the case. HEPA-If you have a filter before you turn on, otherwise the motor may overheat and the air will not be cleaned, then you can set the device on a flat horizontal surface, allowing free air flow from all sides.
To work efficiently, it is important to keep distances to walls and furniture: optimally retreat at least 20-30 cm from vertical surfaces so that air can circulate freely through the inlets. Do not put the cleaner in niches or closed cabinets, as this violates the aerodynamics of the device.
Once physically placed, connect the device to the power grid. When you first turn on, the indicators may flash to signal a system check. The touch panel on the top of the housing should light up, showing the current level of air pollution. If the indicator is lit in red or orange immediately after turning on in a new room, this is normal - the sensor needs time to calibrate.
It is important to choose the right place to place so that the dust sensors read the real room readings, not local contaminants.
Control from the panel and basic modes
The basic control of the device is through the touchpad located on the top cover. Even without connecting to the smartphone, the cleaner is able to operate in several automatic modes. The on/off button is usually combined with switching modes or is made separately depending on the model, for example, Mi Air Purifier 3H or 4 Pro.
The main mode of operation is automatic. In this state, the device independently adjusts the fan rotation speed depending on the readings of the laser air quality sensor, if you cook food or in the room is dusty, the purifier will go to high speeds, and when the air is clean, it will reduce the speed to a minimum to save energy.
There's a night mode for quiet nighttime, which not only reduces noise, but also turns off the lights to keep the bright screen from disturbing sleep, and allows the user to set the fan's desired speed by hand, ignoring the sensors.
- π Night mode: minimizes noise and turns off the display for a comfortable sleep.
- π "Favorite" mode: allows you to set user speed and time settings.
- π Automatic mode: smart power adjustment based on sensor data PM2.5.
- π§Ή Cleaning mode: maximum power for quick air purification after ventilation.
β οΈ Warning: Do not cover the top of the device while operating, especially in the outlet area, to avoid overheating the engine.
Switching between modes is done by pressing a button for a short time, and the display will display the current rotational speed or air quality level in numerical terms (PM2.5 concentration).
Connection to the Mi Home app
Extended control is provided by connecting the cleaner to the smart home system through the Mi Home app, which allows you to remotely monitor air quality, adjust schedules and receive notifications about the status of filters. To get started, make sure that your smartphone is enabled Bluetooth and geolocation.
Launch the app and press the add button. The system will automatically find nearby gadgets. If the automatic search fails, select the cleaner from the list manually. During pairing, you may need to enter a password from the Wi-Fi network. Make sure your router is running at 2.4 GHz, as many cleaner models do not support 5 GHz networks.
Once connected, you can see detailed real-time statistics, not only PM2.5 levels, but also temperature and humidity (if the model is equipped with appropriate sensors), and remote control allows you to turn on air purification before you come home to enter a fresh room.
In the device settings in the app, you can activate the lock from children so that curious kids do not change the settings with buttons on the case. QR-code to quickly check the originality of filters.
- π± Remote Control: Turning on and off from anywhere in the world.
- π Statistics: schedules of changes in air quality for the day, week or month.
- β²οΈ Timers: setting up the schedule of on and off by days of the week.
- π Lock: Protecting the control panel from accidental child pressing.
Scenario setting and automation
One of the most powerful features of Xiaomi's ecosystem is the ability to create complex automation scenarios: You can link an air purifier to other smart home devices to create a truly intelligent environment. For example, a cleaner can turn on automatically when a window opening sensor detects that a window has been closed after airing.
The scenarios are created in the Automation section of the Mi Home app, and the logic is built on the "If... then..." You can customize the purifier's response to data from other sensors, such as temperature sensors, humidity sensors, or even smart locks, which makes a simple appliance part of a larger ecosystem.
Inside the spoiler are hidden examples, but you can come up with your own combinations based on your familyβs needs and the availability of other gadgets.
Automation allows you to forget about manual control. Smart scenarios take over the job, ensuring the optimal climate without you, which is especially convenient if you have pets or allergies, for which clean air is critical.
β οΈ Attention: For scenarios, a stable Internet connection is required, local script execution depends on the presence of a hub or gateway.
Filter replacement and maintenance
Regular maintenance is key to a long life of the device. The main consumable is a composite filter that includes a pre-cleaning layer, HEPA-The life of the filter depends on the air pollution in your area and the intensity of use, but on average it lasts 3 to 12 months.
Mi Home tracks the remaining filter life as a percentage. When the resource is over, the purifier display will light up and the phone will receive a notification. You shouldn't ignore these signals: a clogged filter creates high air resistance, which makes the motor run with overload and reduces cleaning efficiency.
βοΈ Check before buying a new filter
To replace the filter, open the back or bottom cover (depending on the model), remove the old cartridge and install a new one. After installation, reset the filter counter, this is done by pressing the reset button on the case (usually 5-7 seconds) or through the menu in the application.
In addition to replacing the filters, it is recommended to wipe the air quality sensor on the back wall with a dry soft cloth once a month, and the dust on the sensor can distort the readings, causing the device to work incorrectly.
| Type of filter | Term of service | Signs of pollution | Can I wash? |
|---|---|---|---|
| Preliminary | 2-4 weeks | Visible dust, wool | Yeah (vacuum cleaner) |
| HEPA | 6-12 months | Darkening, smelling | No. |
| Coal | 6-12 months | Smells appearing | No. |
| Sensor PM2.5 | Constantly. | Incorrect testimony | Dry cleaning |
Problem Solving and Diagnostics
Even reliable appliances can sometimes run into problems. Most often, users have difficulty connecting to Wi-Fi. If the cleaner is not visible on the network, try resetting the network settings on the device itself by holding two buttons on the panel simultaneously (usually the on button and the mode button) for 5-7 seconds.
Another common problem is that the smell of a foreign filter is changed, and it is normal for new carbon filters to go away after 2-3 days of operation, and if the smell doesn't go away or resembles a scorched plastic, check if the plastic packaging is removed from the new cartridge.
If the indicators flash in a certain way, refer to the instructions for decrypting the error code. Often flashing indicates problems with the engine or sensor, which requires contacting the service center.
Remember to check firmware updates in the app periodically. The software is regularly updated, improving the algorithms of the sensors and adding new features.
