Choosing Xiaomi’s ultrasonic air humidifier is not as easy as it seems, with more than a dozen models with different characteristics, design and functionality, some for a small bedroom, others for a large living room, and others for a stylish accent in a modern interior. But how not to make the mistake of choosing and pay for unnecessary functions?
In this article, we analyzed 5 of Xiaomi’s most popular ultrasonic humidifiers (including Mi Smart and Smartmi models), compared them by key parameters: performance, noise level, tank volume and ease of management. You will learn which model is optimal for the nursery, which will suit allergies and which will be the best budget option, and we will also reveal hidden shortcomings that the manufacturer does not mention in the official characteristics – for example, why some humidifiers require distilled water, despite the stated “universality”.
Why is Xiaomi’s ultrasonic humidifier the best choice for a home?
Xiaomi’s ultrasonic humidifiers stand out from the competition for their combination of technology, design and affordable price. Unlike traditional steam or mechanical models, they operate almost silently (25-38 dB), consume minimal electricity (10-25 watts), and feature smart features ranging from control via the Mi Home app to automatic humidity maintenance.
Key advantages of Xiaomi ultrasonic models:
- 🔹 Precise regulation of humidity – hygrostat sensors maintain a predetermined level with an error ±3–5%.
- 🔹 Safety – no hot steam (unlike steam humidifiers), which is critical for families with children.
- 🔹 Compact - models weigh 1–2 Kg and take up a minimum of space (e.g. Smartmi Air Humidifier) JSQ06 size 20×20 centimeter).
- 🔹 Integration into the ecosystem – compatibility with Google Assistant, Apple HomeKit and voice assistant Alicia.
But there are downsides to this technology: Ultrasonic humidifiers require regular cleaning (every 1-2 weeks), otherwise the membrane will become plaque and bacteria enter the air, and some models will also require distilled or filtered water, otherwise white plaque will cover the furniture, and we will explain this in detail in the maintenance section.
Top.-5 Xiaomi ultrasonic humidifiers: a comparative table
To make it easier to choose, we have compiled a table with key characteristics of popular models, and note the Features column, which lists nuances that the manufacturer does not always advertise (for example, the need to use distilled water).
| Model | Volume of reservoir (l) | Area (m2) | Noise level (dB) | Power (W) | Features | Price (≈) |
|---|---|---|---|---|---|---|
| Smartmi Air Humidifier JSQ06 | 4 | 20–35 | ≤38 | 25 | UV lamp for disinfection, works with Mi Home, requires distilled water | 4 500 ₽ |
| Xiaomi Mi Smart Antibacterial Humidifier | 4.5 | 25–40 | ≤35 | 28 | Antibacterial coating, 12-hour timer, but poor performance at low temperature | 5 200 ₽ |
| Smartmi Evaporative Humidifier 2 | 5 | 30–50 | ≤30 | 15 | Evaporative type (not ultrasonic!), does not require distilled water, but noisier at max mode | 6 800 ₽ |
| Xiaomi Mi Air Humidifier Pro | 5.5 | 35–60 | ≤32 | 30 | Oh.LED-Apple HomeKit, but expensive service (replacement of filters) | 8 000 ₽ |
| Smartmi Air Humidifier JSQ07 | 3.5 | 15–25 | ≤25 | 12 | The quietest model, ideal for children, but a small tank | 3 800 ₽ |
The table shows that the Smartmi JSQ06 is the best value for money – it is suitable for most apartments (up to 35 m2), has a UV lamp and is cheaper than analogues with similar characteristics. However, if you want a model for a large room (for example, a living room of 50 m2), pay attention to the Mi Air Humidifier Pro – a high price, he justifies it with performance and integration with HomeKit.
💡
For bedrooms or children, choose models with noise levels ≤30 dB (JSQ07 or Mi Smart Antibacterial).
Hidden disadvantages of Xiaomi ultrasonic humidifiers: what do not write in the instructions
The manufacturer often keeps silent about the actual maintenance costs and limitations of the devices, and this is what you need to know before buying:
⚠️ Attention: All Xiaomi ultrasonic humidifiers (except evaporative ones) require distilled or filtered water. Using tap water on the membrane creates limestone plaque, and microparticles of minerals enter the air that settle on furniture in the form of white powder. This not only spoils the interior, but can also cause allergies.
Other important nuances:
- 🔋 The membrane lasts 1-2 years for daily use, and it costs 1,000-1,500 to replace. ₽ (spare parts).
- 🧼 Cleaning – if you don’t wash the tank once a week, bacteria multiply inside (even if you have a UV lamp.
- 🌡️ Performance in winter – at lower temperatures +15°C humidification efficiency drops by 30 to 40 percent, critical for unheated spaces.
- 📱 App Dependence – In some models (for example, Mi Air Humidifier Pro) without Mi Home, you can not set a schedule or turn on the UV lamp.
Another point is warranty obligations: Xiaomi refuses warranties if the humidifier breaks down due to tap water use (even if the instructions do not explicitly state this), so keep your distilled water or filter checks.
How often should I change the water in the humidifier?
Which Xiaomi Moisturizer is Best for a Baby Room?
Three parameters are critical for children: noise level (not higher than 30 dB), safety (no hot steam and sharp corners), and humidification quality (no risk of spreading bacteria).
- Smartmi Air Humidifier JSQ07 is the quietest model (25 dB), compact and lightweight (1.2 kg). Suitable for a room up to 25 m2. Minus is a small tank (3.5 l), which will have to be added every 8-10 hours.
- Xiaomi Mi Smart Antibacterial Humidifier – equipped with antibacterial coating and UV lamp, which is important for protecting the airway of the child. Noise – 35 dB (a little louder than JSQ07, but tolerant).
If your child is sensitive to sleep, choose JSQ07. Mi Smart Antibacterial is better for allergic or often ill children — despite the higher noise level, it is more reliable disinfects water. Note that in a baby humidifier, you should stand at least 1 meter from the bed to avoid overhydration of the respiratory area.
💡
Before buying, check if the model has a warm steam mode (available in Mi Smart Antibacterial) that is useful in winter when cold ultrasonic fog can create discomfort.
Budget vs Premium: Which is better: Smartmi JSQ06 or Mi Air Humidifier Pro?
The difference in price between these models is almost 3,500. ₽. Should we overpay? Let's go through the points:
| Parameter | Smartmi JSQ06 (4 500 ₽) | Mi Air Humidifier Pro (8 000 ₽) |
|---|---|---|
| Area of coverage | up to 35 m2 | up to 60 m2 |
| Noise level | 38 dB | 32 dB |
| UV lamp | There is. | Have (+ antibacterial filter) |
| Management | Mi Home, buttons | Mi Home, HomeKit, OLED-display |
| Expenditure | Membrane (1,200) ₽/year) | Membrane + filter (2,500) ₽/year) |
Mi Air Humidifier Pro is justified if:
- 🏡 You have a large room (40)+ m2) or open layout.
- 📱 Integration with Apple HomeKit is important for you (for example, for geolocation automation).
- 🦠 Family has allergies - an additional antibacterial filter reduces the risk of mold spread.
In all other cases, the Smartmi JSQ06 is a smarter choice, it's cheaper to maintain, and in the basic parameters (humidification, noise, safety) it's almost as good as the "dryer" except for the display: there's no screen in the JSQ06, and you'll have to control the settings via your phone.

How to extend the life of Xiaomi moisturizer: 5 rules of care
The average life of ultrasonic humidifiers is 3-5 years, but if they are used improperly, they break down after a year.
- Use only distilled water (or filtered with a hardness of ≤2 mg-eq/L). Tap water will clog the membrane with a plaque in 2-3 months.
- Wash the tank every 3-4 days with a weak solution of vinegar (1:1 with water) or citric acid. Do not use brushes - they scratch the antibacterial coating.
- Keep the humidifier dry. If you don't use it for longer than a week, drain the water and dry the tank with a fan.
- Don't put it near the heater. The temperature difference accelerates the formation of plaque on the membrane.
- Change the membrane every 1 to 1.5 years, signs of wear and tear: decreased productivity, white coating on furniture, unpleasant smell.
⚠️ Warning: If the humidifier starts spitting with water or gurgling sounds, this is a sign of contamination of the sprayer. Wash it immediately under running water (no detergents!) and dry. If the problem recurs, you need to replace the membrane.
For models with a UV lamp (Smartmi JSQ06, Mi Air Humidifier Pro), additionally check the lamp once a month. If it does not turn on or shines dimly, contact the service center.
