Some devices are suitable for the bedroom, others for a children's or spacious living room, and others will cope with dry air in the office. But how not to make a mistake and pay for unnecessary options?
In this guide, we analyzed the 7 most popular Xiaomi humidifiers (including the Mi Smart, Deerma and Viomi models), compared them on 12 key parameters – from noise level to compatibility with Mi Home – and identified the best options for different tasks, and also analyzed the hidden shortcomings of ultrasonic models, which the manufacturer does not mention, and explained why in some cases it is better to choose a traditional evaporative humidifier.

Before comparing specific models, define the basic requirements. Here's what's really important:

- 💧 Type of humidification: ultrasonic (quiet but require distilled water), evaporative (natural humidification, but noisier), steam (powerful, but energy-consuming).
- 🔋 Tank volume: 2 to 6 liters. Choose 4 for round-the-clock work.+ litre.
- 📱 Smart Control: Mi Home support, voice control (Alice, Google Assistant), timers and scripts.
- 🔇 Noise level: up to 30 dB for the bedroom, up to 40 dB for the nursery, 45+ dB – only for daily use.
Notice the additional features that are often crucial, like the aromacapsule for essential oils, the nighttime lighting or the hygrostat (automatic humidity maintenance), but remember, you have to pay extra for each "chip" you have.

Viomi V-HUM01: an evaporative moisturiser for allergic people
If you're looking for natural humidification without white coating, this is your choice, and unlike ultrasonics, it works by evaporation, where water passes through a filter, and the fan distributes moist air, and there's no risk of overhydration or condensation.
Important details: The filter here needs to be changed every 3-6 months (cost) ~800 ₽), But it's justified -- it's up to 99 percent bacterial and dust-retaining. V-HUM01 It can work as an air purifier (removes formaldehyde and pollen).
⚠️ Note: Do not use this humidifier in rooms with temperatures below 15°C – the efficiency of evaporation drops sharply.
Deerma DEM-F600: budget and silent
The most affordable model in the Xiaomi lineup, but with a surprisingly low noise level - only 28 dB. This is comparable to a whisper! Perfect for bedrooms or small rooms (up to 20 m2). Of the cons - a small tank (3.5 l), which is enough for 8-10 hours of work at maximum power.
The secret to silence is the unique design of the membrane, which vibrates at a minimal amplitude, but here's the caveat: if you pour in ordinary tap water, the membrane will quickly become coated with plaque, and the device will begin to make noise, so distilled water is mandatory.
💡
To extend the life of the membrane, once a week wash the tank with a weak solution of citric acid (1 tbsp. spoon per 1 liter of water).
Ultrasonic vs evaporative: Which Xiaomi Humidifier to Choose?
This is the main question that plagues customers, and let's see what's best for your task:
| Parameter | Ultrasonic. | Evaporative |
|---|---|---|
| Noise level | 25-35 dB (shut) | 35-45 dB (fan noise) |
| Water consumption | 300-500 ml/hour | 150-300 ml / h (more economical) |
| Water requirements | Only distilled | You can tap water. |
| Service | Cleaning the membrane 1 time per week | Replacement of the filter 1 time in 3-6 months |
| Security | The risk of white raid | Natural hydration, no plaque. |
Bottom Line: Mi Smart, Deerma is suitable for bedrooms and offices where low noise is important, and Viomi is suitable for children, for rooms with allergies or where there is no possibility to buy distilled water.
Hidden shortcomings of Xiaomi humidifiers: what do not write in advertising
Even the top models have some non-obvious downsides that the manufacturer doesn't mention, and we've compiled them from user feedback and tests:
- "White coating on furniture: All Xiaomi ultrasonic humidifiers spray water with calcium and magnesium salts. If you use tap water, in 2-3 weeks, there will be white plaque on furniture, walls and appliances. Solution: only distilled water or special softener cartridges (stands). ~500 ₽).
- Wi-Fi problems: Many people complain that Mi Smart and Viomi humidifiers lose touch with Mi Home after a firmware update. The reason is an unstable Wi-Fi module. Solution: connect the device to a 2.4 GHz network (5 GHz is not supported!) and place the router no further than 5 meters.
- Air humidification: Ultrasonic models do not have a built-in hygrometer (except for the Mi Smart Antibacterial Humidifier 2). If left to run at maximum, humidity can rise to 70-80% - this is harmful to health and furniture. Solution: buy a separate hygrometer (from 300 times). ₽) Choose models with automatic humidity control.
⚠️ Warning: If Xiaomi's humidifier starts making clicking sounds or smells of plastic, disconnect it immediately! This is a sign of membrane overheating or short circuit. These are rare but recorded in reviews (especially on Deerma 2020-2021 models).
