Choosing a Xiaomi air humidifier isn’t as easy as it sounds, with several models with different technologies (ultrasound, evaporation), tank size and additional features, some for the bedroom, others for the children’s room or the big room, and smart models with integration into the Mi Home that can be controlled from a smartphone.
In this article, we’ll break down all of Xiaomi’s current humidifiers (including Smartmi and Viomi sub-brands), compare them by key parameters: performance, noise level, ease of service and price. You’ll learn which model is better at handling dry air in winter, which is best for allergy sufferers and which will last longer without frequent cleaning.
Why is Xiaomi Humidifier a Good Choice?
Xiaomi’s humidifiers stand out from the competition for their combination of price, technology and design, and here are their key advantages:
- 💧 Effective technologies: ultrasonic models (such as Smartmi Air Humidifier 2) spray water evenly and evaporative ones (like Viomi) V1) less susceptible to plaque formation.
- 📱 Smart management: most devices support the Mi Home app, where you can set a schedule, monitor humidity levels and receive notifications.
- 🔇 Low noise level: even in night mode, many models emit no more than 30 dB - it is quieter than a whisper.
- 💰 Price/quality ratio: the functionality of Xiaomi humidifiers are often not inferior to premium brands, but are 1.5-2 times cheaper.
The brand also regularly updates its lineup with useful chips, including antibacterial filters, temperature sensors and even flavoring, and the modular design of many parts (such as membranes or cartridges) can be replaced by itself.
Key parameters when choosing a humidifier
Before we compare specific models, we'll figure out what to look for when buying, and these parameters will determine whether the device will cope with the task and will not cause problems in operation.
1. Type of moisturiser
Xiaomi offers two main types:
- 🌊 Ultrasonics: spray water with high-frequency vibrations. Pros: high performance, compactness. Cons: require distilled water (or plaque), can humidify the air.
- ☁️ Evaporative (traditional): water evaporates naturally through the filter. Pros: self-regulation of humidity, less plaque. Cons: noisier, filters need to be changed.
Productivity and coverage area
Focus on the size of the room:
- 🛏️ Up to 20 m2: models with a consumption of 200-300 ml / h (for example, Xiaomi Smartmi Air Humidifier Lite) are suitable).
- 🏠 20-40 m2: you need devices with a consumption of 300-500 ml / h (Smartmi Air Humidifier 2).
- 🏢 More than 40 m2: consider powerful models of the Viomi type V3 (up to 600 ml/h).
3. The volume of the reservoir and autonomy
The bigger the tank, the less water you need to add.
- 💧 2-3 liters: enough for 8-12 hours of work (night or working day).
- 💦 4-6 liters: autonomy up to 24-36 hours (comfortable for large rooms).
Noise level
For bedroom or nursery, choose models with night mode (≤For example, Xiaomi Smartmi Air Humidifier 2 in minimal mode produces only 26 dB – this is quieter than the ticking of a wall clock.
Additional functions
Useful options that will make it easier to use:
- 📊 Hygrostat: automatically maintains the specified humidity.

- 🍃 Aromacapsule: for adding essential oils (available in Viomi) V2).
- 🦠 Antibacterial coating: prevents germs from multiplying in water.
💡

1. What water do you pour?
For ultrasonic models (Smartmi Air Humidifier 2, Viomi) V3) use:
- 💧 Distilled water is ideal (no plaque).
- 🚰 Filtered (through reverse osmosis) - permissible, but the plaque will form more slowly.
For evaporative (Viomi) V1) You can also fill the water pipe, but it is better to filter it too.
2. How often do you clean?
Minimum frequency:

- 🆔 Every 3-6 months: change filters (in evaporation models).
☑️ Cleaning Xiaomi moisturizer
3. Optimal humidity
Make sure that the humidity in the room is within the limits 40–60%. Too high a level (>70%) It helps to multiply mold, and low (<30%) slimy.
In the Mi Home application, you can configure automatic humidity maintenance (if the model supports a hygrostat).
💡
In summer, you may not need a humidifier, so check with a hygrometer, and in winter (when heating is running), humidity often drops below 30%, and the device will work almost constantly.
Frequent errors in selection and operation
Many users are facing problems because of the wrong approach.
⚠️ Warning: Never use essential oils in humidifiers not designed for this (e.g. Smartmi Air Humidifier Lite).The oils spoil the plastic and membrane, and can also cause allergies when sprayed.
Other common mistakes:
- 🚫 Pour water above the maximum mark - this leads to leaks and breakage of the pump.
- 🚫 Put a humidifier next to furniture or walls - moisture condenses on surfaces, mold appears.
- 🚫 Ignore filter replacement – in evaporative models, this reduces performance and degrades air quality.
⚠️ Warning: If the humidifier starts to smell "raw," immediately rinse it with a solution of hydrogen peroxide (3%) and dry it in the sun.
