Why cleaning Xiaomi humidifier is not just hygiene, but the key to its long work
Xiaomi’s ultrasonic humidifiers (Smartmi, Mi Air Humidifier, and others) have become an integral part of many homes because of their efficiency, quiet operation, and integration into the smart home ecosystem. However, few people realize that irregular or improper cleaning reduces the life of the device by 30-40%, and also turns it into a breeding ground of bacteria. The moisture remaining in the tank and on the membrane creates the perfect environment for mold, microorganisms, and even lime plaque — especially if you use hard water.
In this article, we'll look at not only the basic washing procedure, but also the nuances that are not covered in the official instructions, such as why you can't clean the membrane with abrasives, how to dry the device properly after washing, and what folk methods (like vinegar or citric acid) really work and which can harm. If your humidifier starts to emit an unpleasant smell, it's worse to spray steam or there's a white coating on the inside, this is a signal that it's time to act.
Before you get into practice, remember that cleaning Xiaomi's humidifier is different from caring for traditional steam models. Ultrasonic technology involves a sensitive ceramic membrane that is easy to damage. And integration with the Mi Home app adds another layer of complexity - after improper assembly, the device may not sync with the network. But don't worry: following our recommendations, you will avoid all these problems.
Preparation for cleaning: what you need and how to de-energize the device
Before you start washing, make sure that the humidifier is completely off the grid. It's not enough to just press the power button on the case -- remove the plug from the socket! This will prevent short circuits if water accidentally hits the electronic components.
- 🧼 Soft sponge or microfibre wipe (without hard pile!)
- 🧴 A dishwashing agent (better without flavorings) or a specialized cleaner for humidifiers
- 🍋 Citric acid or vinegar 9% (for scale removal, but not for membrane!)
- 🧻 Paper towels or clean drying cloth
- 🔧 Small brush (for example, toothbrush) for hard-to-reach places
If your model supports automatic shutdown when there is no water (e.g. Xiaomi Mi Air Humidifier 2), don’t take the risk of physically disconnecting the cord. Also check if there is any water left in the tank. Pour it through a special hole (usually marked with the WATER OUT icon). Some users forget this step, and when the device is turned over, water enters the vents, which leads to breakage.
⚠️ Warning: Never use chlorine, bleach or harsh chemicals to clean your Xiaomi humidifier, which destroy sealing gums and membranes, and can be dangerous if inhaled after switching on the device.
Step-by-step: how to disassemble and wash the Xiaomi humidifier
The cleaning process can be divided into three stages: disassembly, washing of components and drying. Let's start with disassembly. In most Xiaomi models (for example, Smartmi Air Humidifier JSQ01ZM), the algorithm is as follows:
- Remove the top cover by pulling it up (usually it is fixed with latches).
- Remove the water tank – in some models, you need to press the UNLOCK button.
- Disconnect the base to the membrane and the fan, and it's usually mounted on a thread or latches.
- Get a filter (if you have one in your model) and a membrane – it looks like a round ceramic disc.
Now, start with the tank, fill it with warm water (not above 40°C) and add a few drops of dishware. Wash the interior walls carefully with a sponge, paying attention to the corners where the plaque accumulates. To remove lime deposits, you can use a solution of citric acid (2 tbsp per 1 liter of water) - pour it into the tank and leave it for 30-60 minutes, then rinse it.
Clean the membrane separately! No abrasives or acids, just a soft sponge and water. If there is white plaque on the membrane, gently wipe it with a napkin dipped in a weak vinegar solution (1:1 with water), but do not leave it for long. Xiaomi recommends replacing the membrane every 1-2 years, but with careful care it will last longer.

Cleaning the filter and fighting mold: what to do if the humidifier smells
The filter in Xiaomi humidifiers (if it is provided by the design) requires special attention. In models such as Smartmi Air Humidifier 2, an antibacterial filter is used, which over time is clogged with microorganisms. It can be washed under running water, but not more than 1 time every 2 weeks - otherwise it will lose its properties. If the filter has become hard or changed color, it is time to replace it (original filters for Xiaomi are sold in brand stores or on AliExpress).
If the humidifier is odorless, it is a sure sign of mold or bacterial contamination. In this case, a standard wash is not enough. Prepare a disinfectant solution: mix 1 liter of water with 1 tbsp. l. hydrogen peroxide (3%) or use a specialized humidifier (for example, Ballu Cleaner). Pour the solution into the tank and turn the device on for 5-10 minutes in maximum spray mode (but do not breathe this steam!).
For mold prevention:
- 💧 Use distilled or filtered water (hard water accelerates plaque formation).
- ☀️ After each use, drain the water and dry the tank.
- 🌿 Once a month, conduct a deep cleaning with disinfection.
⚠️ Warning: If the smell is still there after cleaning, check if the mold has accumulated in the ventilation ducts of the base. Use cotton swabs soaked in alcohol to clean them, but do not pour the liquid inside!
How to dry and collect a humidifier after washing: errors that spoil the device
One of the most common myths is that the humidifier can be harvested immediately after washing, and in fact, wet parts (especially the membrane and electronic contacts) lead to short circuits or corrosion.
- Wipe all components with a dry microfiber wipe.
- Leave them to dry in the air for at least 2-3 hours (preferably in the sun or in a well-ventilated place).
- Make sure that there are no drops of water left in the tank and base.
When assembly, make sure that:
- 🔌 The membrane is installed evenly, without distortions (otherwise the device will vibrate and make noise).
- 🔒 All latches and threaded connections are securely fixed.
- 💡 The filter (if any) is in the correct position (usually marked). TOP).
After assembly, don't turn on the humidifier right away. Pour the water, wait 5-10 minutes and check if there are any leaks. If the device is connected to the Mi Home, sync it again through the app - sometimes after cleaning, you need to reconnect.
💡
If the humidifier makes a loud noise or vibration after assembly, it's likely that the membrane is curved, disassemble the device and repeat the assembly, making sure the disc is flat.
Cleaning frequency: Xiaomi moisturizer care schedule
How often you should wash your humidifier depends on the intensity of use and the quality of the water, and we have compiled a table with recommendations for different scenarios:
| Conditions of use | Frequency of cleaning | Type of cleaning |
|---|---|---|
| Daily use, hard water | 1 time 3-4 days | Washing the tank, checking the membrane |
| Use 2-3 times a week, filtered water | 1 time per week | Full wash + disinfection 1 time per month |
| Seasonal use (winter) | Before the first inclusion and once every 2 weeks | Deep cleaning with scale removal |
| Storage (not used) | Before cleaning for storage | Washing, drying, filter removal |
If you notice at least one of these signs, clean up immediately, regardless of the schedule:
- 🌫️ White plaque on walls or membranes.
- 👃 Unpleasant smell at work.
- 💧 The steam volume decreased or the device became noisy.
- 🔴 There was an error on the display (for example, E1 or E2 screen-model).
💡
The use of distilled water reduces the cleaning frequency by 40% and prolongs the life of the membrane by 2 times.
Top.-5 Mistakes when cleaning the Xiaomi moisturiser: what shortens the life of the device
Even experienced users sometimes make mistakes that cause the humidifier to break, and here are the most common ones:
- Using hard brushes or abrasives to clean the membrane, which causes microcracks, and the device stops generating steam.
- Drying the membrane with a hair dryer or on a battery, and a sudden temperature difference deforms the ceramics, and the membrane loses its properties.
- Soaking the electronic unit in water, even if it seems sealed, the contacts can oxidize.
- Using aromatic oils in water, they clog the membrane and leave a sticky coating that can't be washed away.
- Storing a humidifier with water inside, and it causes bacteria to multiply and metal parts to corrosion.
Another common mistake is ignoring the display errors, like the E1 code in Xiaomi humidifiers often means that the membrane is contaminated or not installed correctly. Many people just reboot the device, but that doesn't solve the problem, so you better take the humidifier apart and check the membrane.
