The Xiaomi Smartmi Zhimi Air Humidifier 2 is one of the most popular solutions for maintaining the optimal microclimate in the apartment. This device combines ultrasonic spraying technology, smart control through the Mi Home app and a compact design that will fit into any interior. However, even such a simple at first glance gadget has nuances of installation that affect its efficiency and durability.
In this article, we'll take you through the whole process, from unpacking the box to fine-tuning it with your smartphone, how to install filters correctly, avoid errors when you first turn on, connect the device to Wi-Fi, and set up automatic modes, and we'll also reveal some hidden features that aren't mentioned in the official manual, but that make it much easier to use the humidifier in everyday life.
1. Unpacking and inspection of equipment
Before installing, be sure to check the contents of the box. As standard, the Xiaomi Smartmi Zhimi Air Humidifier 2 should be:
- 📦 Main humidifier block with cover
- 💧 Removable water tank (usually already inserted into the body)
- 🔋 Power cable with adapter (depending on the region may differ fork)
- 🧼 Water filter (most often already installed inside the tank)
- 📄 Short instructions in several languages (including Russian)
- 🔧 Cleaning tool (in some versions)
If something is missing, don't turn on the device, go to the Xiaomi store or support service, pay special attention to the filter: it should be whole, without tearing or deforming, a damaged filter will not only reduce the efficiency of hydration, but can also become a source of bacteria.
⚠️ Warning: In some batches of humidifiers, the filter comes in a separate package inside the tank.
Also check the case for cracks or chips, even minor damage can lead to water leaks when working. If you bought the device from hand, be sure to check if it was in use, this will indicate traces of scale inside the tank or foreign smells.
Preparation for the first incorporation: installation of the filter and water pouring
Before the first run, you need to install the filter correctly and pour water, which is often missed, but depends on how long the device lasts and how much steam will be quality.
Filter installation
The filter in Smartmi Zhimi Air Humidifier 2 has two functions: it softens water (reduces scale formation) and it traps large impurities.
- Remove the top lid of the moisturiser by pulling it up.
- Remove the water tank - it is attached to the latches, so just pull it on yourself.
- Wash the tank with warm water (without detergents!).
- Take the filter out of the package and place it in a special slot at the bottom of the tank. It should lie flat, without skewing.
- Make sure the filter fits tightly to the walls – this will prevent unfiltered water from entering the device.
If the filter is installed incorrectly, the humidifier will work, but the spraying efficiency will decrease, and the furniture may appear white plaque from hard water.
Pouring water
Use only pure drinking water, boiled or bottled, and tap water, even filtered, can contain salts and impurities that will eventually clog the humidifier membrane.
- 🚰 Pour water into the tank through the top hole, the maximum level marked on the inner wall.
- 🔄 Do not add water to the top - leave 1-2 cm to the edges, otherwise when transferring the tank water can spill.
- 🚫 Do not use distilled water – it is too soft and can damage the ultrasonic membrane.
After pouring the water, gently place the tank back into the case until you hear a click. Make sure it's up straight - skewings can lead to leaks.
☑️ Preparation for first inclusion
3. Electrical connection and first switching on
Now you can plug the humidifier into the socket, use only the original power adapter that came with it, and you can't plug it in through the extension cords or tees, because it's sensitive to voltage changes.
After you connect to the network, the power indicator will light up on the front panel. If it's not burning, check:
- 🔌 The density of the cable connection to the humidifier and socket.
- 🔋 Power of the socket (connect another device).
- 🛠️ Integrity of the cable (whether there are inflections or damages to the insulation).
When you first turn on, the humidifier can emit a short beep, which is normal. If the signal is repeated or accompanied by a flash of an indicator, this indicates an error.
| Signal. | Meaning | Action. |
|---|---|---|
| 1 short signal | Successful inclusion | The device is ready to go. |
| 3 short signals | No water in the tank. | Reload the water and restart the device |
| 5 short signals | The filter is installed incorrectly | Check the position of the filter in the tank |
| Continuous flashing of the indicator | Critical error (overheating, clogging) | Disconnect the device and contact the service |
If the humidifier is successfully switched on, press the power button on the front panel to start it manually. By default, the device will operate at medium power.
💡
To check the operability of the humidifier, hold your hand to the steam outlet at a distance of 10-15 cm. You should feel a light flow of cool air 1-2 minutes after turning on.
4. Wi-Fi connection and setup via Mi Home
One of the key benefits of Smartmi Zhimi Air Humidifier 2 is the ability to control through the Mi Home app, which allows you to adjust your schedule, control humidity remotely and integrate the device into the smart home system.
Step 1: Installation of the Mi Home app
If you don’t have an app yet, download it:
- 📱 For iOS (App Store)
- 🤖 For Android (Google Play)
Once installed, sign up or log in to your Xiaomi account. If you already have other ecosystem devices (like a robot vacuum cleaner or lamp), the humidifier will automatically appear in the shared list.
Step 2: Adding the device to Mi Home
To connect the humidifier:
- Open Mi Home and press «+» top-right.
- Select the category "Humidizers".
- In the list, look for the Zhimi Air Humidifier 2 (or Smartmi Evaporative Humidifier 2 in some versions).
- Make sure the humidifier is on and near the phone (no more than 2 meters away).
- Connect to a 2.4 GHz Wi-Fi network (the device does not support 5 GHz!).
- Follow the instructions in the application: it will prompt you to press and hold the button on the humidifier until the indicator blinks.
If the device is not located, try:
- 🔄 Reset the humidifier (disconnect and turn on the power).
- 📶 Switch to another Wi-Fi network (e.g. mobile hotspot).
- 📱 Update the Mi Home app to the latest version.
⚠️ Note: If your router only works in the 5GHz band, you will need to enable 2.4GHz compatibility mode in the router settings.
Step 3: Basic settings in the application
Once you've successfully connected, open your device card in Mi Home. Here you can:
- 🌡️ Set a target humidity level (optimally 40-60%).
- ⏰ Set up a work schedule (for example, turn on an hour before bedtime).
- 💧 Select moisture mode: Auto, Sleep or Turbo.
- 🔔 Include notifications about low water levels or needing to change the filter.
In the section “Settings» (⚙️) Additional functions can be activated, for example:
- 🌿 The "Children's Room" mode (quieter work).
- 🔄 Automatic shutdown when the predetermined humidity is reached.
- 📊 History of weekly humidity changes.
💡
For stable operation of the humidifier over Wi-Fi, make sure that your router does not block UDP-port 53 (DNS) and that in the firewall settings, you are allowed to connect Xiaomi devices.
5. Optimal placement of the humidifier in the room
Even the most perfect humidifier will not work if it is placed incorrectly.
- 🛋️ Distance from furniture: at least 30 cm from walls, cabinets and sofas, this will ensure even distribution of steam.
- 🌿 Height: optimally - at the level of 50-100 cm from the floor (for example, on a table or table).
- 🚫 Prohibited areas: near heat sources (batteries, heaters), under direct sunlight or in places with high humidity (bathroom).
- 📡 Wi-Fi signal: if you plan to control the humidifier through the application, place it in the zone of confident reception of the network.
For a bedroom, the best place is a bedside table 1-1.5 meters from the bed. In the children's room, the humidifier should be located so that the steam does not go directly to the crib or play area.
If there are several rooms in the room and you want to moisten them all, consider moving the device or buying a second humidifier. Smartmi Zhimi Air Humidifier 2 is designed for an area of up to 25-30 m2, so in large spaces its efficiency is reduced.

8 Additional functions and life hacks
Smartmi Zhimi Air Humidifier 2 hides a few useful features that not everyone knows about:
- 🌙 Night mode: activated in the Mi Home app. Humidifier is quieter, and the lights go out.
- 📱 Voice control: if you have Xiaomi AI Speaker or Google Assistant, you can turn your device on/off with voice.
- 🌡️ Automatic adjustment: if you connect the hygrometer Xiaomi Temperature and Humidity Sensor to the humidifier, it will maintain humidity with an accuracy of 1%.
- 🔄 Ionization mode: some firmwares have the option of cleaning air from dust (included in additional settings).
You can also use a humidifier for aromatherapy.
- Buy special aromatic capsules for humidifiers (not essential oils!).
- Place the capsule in the flavouring compartment (usually located on the side of the tank).
- Turn on spray mode - the aroma will spread along with the steam.
⚠️ Warning: Do not add essential oils directly to water! they can damage the plastic and membrane, and cause allergic reactions when sprayed.
If you need to quickly increase the humidity in the room (for example, for colds), use Turbo mode in the application. It increases the intensity of spraying, but reduces the continuous operation time to 4-5 hours.
💡
For maximum efficiency, place the humidifier near a dry air source (such as next to a heating battery in winter) to speed up the distribution of steam around the room.
