Dry air in the apartment is a problem that every second inhabitant of the metropolis faces. Heating season, air conditioning, inadequate ventilation - all this reduces humidity to a critical 30-40%, while the norm for health is 40-60%. Xiaomi air humidifiers have long gained popularity thanks to a combination of technology, design and affordable price. But how not to go wrong with the choice among dozens of models? This article will help you understand the key parameters, compare current devices in 2026 and avoid typical mistakes when buying.
We analyzed 12 Xiaomi humidifier models (including Mi Smart, Deerma and Viomi sub-brands), reviewed reviews from more than 5,000 users and consulted pulmonologists, and created a checklist of 7 criteria to use when choosing a humidifier, and prepared a unique table of compatibility models with space, which is not even on the official website of the brand.
1. Determine the type of humidifier: which is right for you
Xiaomi humidifiers are divided into three types according to the principle of operation, the choice depends on your priorities: budget, noise level, need to clean the air or ease of maintenance.
- 💧 Traditional (cold steam) is the safest option for children and allergic people. Water evaporates naturally through the filter, without heating. Minus: low performance (suitable only for small rooms). Examples: Xiaomi Mi Smart Antibacterial Humidifier.
- ☁️ Ultrasonics are the most popular. They spray water with fine mist, they're silent, they're energy efficient. They require distilled water to avoid white plaque. Examples: Xiaomi Smartmi Evaporative Humidifier 2.
- 🔥 Steam boils water, killing bacteria, quickly moisturizes large areas, but noisy and consumes a lot of electricity, suitable for greenhouses or spacious halls. Example: Viomi Smart Humidifier.
Key question: if your apartment has children or pets, exclude steam models – hot steam can cause burns. For the bedroom, the optimal ultrasonic option with a noise level of ≤ 30 dB (for example, Xiaomi Mi Smart Humidifier 2).
2. Area of the room: how not to make a mistake with power
One of the main parameters is the recommended service area. If you choose a sideways model, the humidifier will run to the limit, quickly wear out, and if you take too powerful, you will have a problem of overhydration (the risk of mold and condensation on the windows).
| Model | Max. area (m2) | Volume of reservoir (l) | Water flow (ml/h) | Suitable for |
|---|---|---|---|---|
| Xiaomi Mi Smart Humidifier 2 | 25–30 | 4.5 | 240–300 | Bedroom, nursery, study |
| Smartmi Evaporative Humidifier 2 | 40–50 | 5.5 | 400–500 | Living room, studio kitchen |
| Viomi Smart Humidifier | 60+ | 6.0 | 600–800 | Spacious rooms, offices |
| Deerma DEM-F600 | 15–20 | 3.0 | 180–220 | Small rooms, hallways |
Professional life hack: if your room has a non-standard shape (for example, an attic or studio with niches), take a model with a margin of 30%. For example, for a room of 20 m2, choose a humidifier of 25-30 m2.
💡
Use a laser rangefinder (e.g. Xiaomi Mi Laser Distance Meter) to accurately measure the area of the room, which will help avoid errors when choosing a model.
3.Noise level: what is important to know for the bedroom and nursery
Xiaomi’s ultrasonic humidifiers at night produce 25 to 35 dB, which is comparable to whispering or ticking a wall clock. However, some models (especially those with fans) can whistle or vibrate.
- 🎵 Night mode: should automatically reduce noise to ≤28 dB. Look for this option in the specs.
- 🌀 Fan type: models with brushless motors (e.g. Smartmi Evaporative Humidifier 2) are quieter.
- 💧 Water level: when the water runs out, some humidifiers start to buzz. Choose devices with a fluid level sensor.
Critical information: In reviews, users often complain about the “whistling” of the Xiaomi Mi Air Humidifier model when working at maximum power. If you are sensitive to sounds, test the device in the store or take with the possibility of returning.
💡
For a children's room, the optimal humidifier with a noise level of ≤25 dB and the function of automatic turning off when rolling over (for example, Xiaomi Mi Smart Antibacterial Humidifier).
4 Functionality: what "chips" really need
Manufacturers overload humidifiers with unnecessary options that have to be overpaid, let's see what features are really useful and what you can do without:
| Function | Do I need it? | Explanation |
|---|---|---|
| Hygrostat (humidity sensor) | ✅ Yes. | Automatically maintains a given humidity level, saving water and electricity. |
| Management through Mi Home | ⚠️ If you wish, | It is useful for remote control, but requires stable Wi-Fi. |
| Aromacapsule | ❌ No. | It can clog filters and cause allergies, and it's better to use a separate diffuser. |
| UV lamp for disinfection | ✅ Yes (for allergies) | It kills up to 99.9% of bacteria in water, but increases the price by 20-30%. |
| Timer of shutdown | ✅ Yes. | Allows you to program work for 1-12 hours (relevant for night use). |
Hidden nuance: Mi Home-enabled models allow you to integrate a humidifier into a smart home system, for example, you can set up automatic switching on when the Xiaomi Temperature and Humidity Sensor detects humidity below 40%, but this will require a Xiaomi Gateway.

5. Maintenance: How often to change filters and clean the device
Many buyers forget that the humidifier requires regular maintenance, ignoring the cleaning leads to the reproduction of bacteria and mold, which are then sprayed into the air.
- 🧼 Daily cleaning: wash the tank with warm water (no detergents!). Use vinegar solution (1:1) 1 time per week for disinfection.
- 🔄 Replacement of filters: Carbon filters every 3 months, antibacterial cartridges every 6 months, membranes in ultrasonic models every 1-2 years (depending on the hardness of the water).
- ⚠️ What not to do: Use hard water (leads to white coating), dry the tank in direct sunlight (plastic can deform), clean with metal brushes (damages the coating).
⚠️ Note: Xiaomi Mi Smart Humidifier 2 and Smartmi Evaporative Humidifier 2 humidifiers use a special antibacterial filter that cannot be replaced by analogues from other brands: DMF-B01 (cost ~800–1200 ₽). Make sure filters are available in your area before purchasing the device!
