Xiaomi’s ultrasonic air humidifiers are among the most popular devices in the brand’s smart home lineup, and are compact, quiet, and efficiently maintain optimal humidity levels. However, even the most modern models are Smartmi Air Humidifier 2, Mi Air Humidifier Pro or Xiaomi Deerma Humidifier. JSQ — Without proper cleaning, scale accumulates inside the tank, bacteria multiply, and the humidifier membrane loses its effectiveness.
In this article, we will analyze the step-by-step cleaning algorithm, taking into account the design of Xiaomi devices, explain which products are safe for plastic and ultrasonic membranes, and warn against typical errors that shorten the life of the device.
Why Xiaomi Humidifier Should Be Cleaned Regularly
Many users only clean the device when they notice the smell of mold or the white coating on the furniture — but these are already critical signs of contamination.
- 🧪 Scaling: The tap water contains calcium and magnesium salts that settle on the membrane and the walls of the tank. Over time, scale reduces the performance of the humidifier by up to 40%.
- 🦠 Bacterial reproduction. Wet environments are the perfect soil for microorganisms. 2-3 For weeks in the water appear colonies of Legionella or Pseudomonas, dangerous to the respiratory tract.
- 🍄 Mold on the filters. If the device is in a dark corner or is rarely used, the cartridges and seals will form a black plaque.
- 🔊 Increased noise. The contaminated membrane vibrates unevenly, leading to rattles and creaks.
The manufacturer recommends cleaning the Xiaomi moisturizer every time 3-5 But the frequency depends on the hardness of the water: in regions with high salt content (for example, Moscow, St. Petersburg), cleaning will have to be carried out more often.
What you need to clean: a list of tools and tools
For high-quality cleaning of the humidifier Xiaomi does not need expensive professional means, enough materials and household chemicals that are safe for plastic:
| Category | Tool/tool | What do you need? | The alternative |
|---|---|---|---|
| Basic funds | Citric acid (50 g) | Scaling and disinfection | Vinegar 9% (100 ml) |
| Soft cleaners | Soft bristles toothbrush | Cleaning of membranes and hard-to-reach places | Cotton swabs |
| Disinfection | Hydrogen peroxide 3% | Destroying bacteria and mold | chlorhexidine |
| Care for the membrane | Distilled water | Post-cleaning flushing | Filtered water |
What can't be used:
- 🚫 Abrasive powders (such as pemoluks or dry soda) – scratching the plastic and membrane.
- 🚫 Hard brushes or metal sponges – damage the ultrasonic element.
- 🚫 Concentrated acids (such as Sanox) – are corrode by sealants.
- 🚫 Essential oils – leave the film on the membrane and can cause allergies when sprayed.
💡
If you have a model with an aromacapsule (for example, Smartmi Air Humidifier) 2S), Clean it separately with alcohol - this will prevent mixing of smells.
Step-by-step: how to clean the Xiaomi humidifier from scale and bacteria
The cleaning process takes 30-40 minutes and consists of 5 Before you start, disconnect the device from the network and drain the remaining water. If the humidifier has not been used for more than a week, soak the tank in warm water on the water. 10 minutes – this will make it easier to remove sediments.
Turn off the humidifier from the socket
Drain the water from the tank.
Remove the filter (if any)
Preparing tools and tools-->
1. Scalling tank cleaning
Pour warm water into the tank (temperature) 40-50°C) and add:
- 🍋 50 g of citric acid (or 100 ml of vinegar) per 1 liter of water.
- ⏳ Leave the solution on. 20-30 minutes (with heavy deposits - up to 1 hour).
- 🧽 Gently rub the walls with a soft sponge. Use a toothbrush for bottlenecks.
2.Mold disinfection and removal
After the scale is removed:
- 🧴 Pour into the tank a solution of hydrogen peroxide (3% concentration) or chlorhexidine.
- ⏱️ Soak for 15 minutes, then rinse thoroughly with running water.
- 🕵️♂️ Check the seal ring on the lid, and it's often black mold that accumulates.
Cleaning of the ultrasonic membrane
The membrane is the most delicate element, and it can't be rubbed or invasively treated.
- 💧 Wash the membrane under a weak stream of water, removing white plaque with your fingers (without pressing!).
- 🧼 Apply a solution of citric acid (1 tsp per 100 ml of water) to a cotton swab and treat the surface carefully.
- 🚿 Rinse with distilled water and dry in air (do not use a hair dryer!).
What happens if you don't clean the membrane?
Filter washing (if any)
Xiaomi Smartmi Air Humidifier Pro and Deerma JSQ-500 They're equipped with interchangeable filters. They're cleaned separately:
- 🔄 Wash the filter under running water (temperature not higher than 40)°C).
- 🧼 For disinfection, soak it for 10 minutes in a peroxide solution.
- ☀️ Dry on a battery or in the shade (direct sunlight destroys the material).
Attention! Filters in Xiaomi moisturizers are designed for 2-3 After that, they need to be replaced, even if they look clean.
5. Assembly and test run
After cleaning all the elements:
- 🔧 Collect a humidifier, making sure that the sealing ring fits tightly.
- 💦 Pour distilled or boiled water (not from the tap!).
- ⚡ Turn on the device and check the work: the steam should be uniform, without flakes or odor.
💡
Use only distilled or filtered water – this will prolong the life of the membrane in the water. 2-3 once.
Typical Mistakes When Cleaning Xiaomi Humidizer and How to Avoid Them
Even experienced users sometimes make mistakes that cause the device to break down, and here are the most common ones:
⚠️ Attention! Never use alcohol or acetone to clean the membrane, they destroy the ultrasonic element. Only hydrogen peroxide or specialized humidifiers (for example, Ballu Cleaner) are suitable for disinfection).
- 🔌 Cleaning the device on, even if the humidifier is on standby, it needs to be disconnected from the network, and getting moisture on the board can cause a short circuit.
- 🧼 Use of detergents for dishes. Fairy or AOS They leave a film that gets into the air when sprayed.
- 🌡️ Boiling water for washing. Hot water deforms plastic and damages the membrane.
- 🕰️ Long soaking. If you leave citric acid in the tank overnight, it can eat the seals.
Another common problem is improper drying, and some users collect the humidifier immediately after washing it, without waiting for it to dry out, and this leads to:
- 💨 The appearance of an unpleasant smell at the first inclusion.
- ⚡ The risk of corrosion of contacts on the board.
- 🦠 Rapid re-formation of mold.
Optimal drying time — 1-2 If you are in a hurry, use the fan at the minimum speed (do not direct air flow to the membrane!).
How to Care for Xiaomi Moisturizer to Clean It Less Often
Compliance with simple operating rules will reduce the frequency of deep cleaning to 1 time in 2 weeks:
- 💧 Use the right water. Distilled or filtered water (for example, after a reverse osmosis system) minimizes the formation of scale.
- 🔄 Change the water daily. Even if the humidifier doesn't work, stagnant water becomes a breeding ground for bacteria.
- ☀️ Dry the device after use. If you don't plan to turn on the humidifier for a few days, drain the water and dry the tank.
- 📱 Watch out for notifications in Mi Home.The app reminds you to clean and replace filters.
For models with hygrosate (such as Smartmi Air Humidifier 2), set up an automatic shutdown when 60% humidity is reached – this will prevent overhydration and mold growth in the room.
💡
If you have hard water in your area, add it to the tank. 1-2 drops of vinegar at each filling - this will slow the formation of scale.
Xiaomi models comparison: which humidifiers require special care
Not all Xiaomi humidifiers are equally easy to maintain, and some models have design features that affect the cleaning process:
| Model | Features of cleaning | Difficulties | Recommendations |
|---|---|---|---|
| Smartmi Air Humidifier 2 | Removable tank, open-type ultrasonic membrane | The membrane is quickly covered by plaque when using tap water | Clean the membrane every 3 days, use distilled water |
| Mi Air Humidifier Pro | Built-in filter, large tank (4.5 liters) | The filter requires monthly replacement, it is difficult to dry the internal channels. | Wash the filter once a week, dry the device with a fan |
| Deerma Humidifier JSQ | Compact size, no interchangeable filter | Rapid formation of mold in the seal of the cover | Treat the seal with alcohol once every 5 days |
| Xiaomi Mi Smart Antibacterial Humidifier | UV lamp for disinfection, silver ion filter | UV lamp requires cleaning from plaque, high filter consumption | Wash the lamp with a cotton swab with peroxide once a month |
If you own a model with an aromacapsule (for example, Smartmi Air Humidifier) 2S), Remember, essential oils settle on the membrane and shorten its lifespan. Use the capsule no more than 2 times a week and flush the membrane after each application.
What to do if the Xiaomi humidifier after cleaning does not work
Sometimes, after cleaning, the device refuses to turn on or does not work correctly.
- 🚨 Not activated: Check if the tank lid is tightly closed (the Smartmi models have a closing sensor). Make sure the seal ring is not offset. If the device does not respond to the button, reset: hold the power button for 10 seconds.
- 💨 Weak steam or flakes in the air: Repeat cleaning the membrane -- likely there's still plaque. Check the water level: in some models, when the vapor level is low, it becomes intermittent.
- 🔊 Heavy noise or vibration: Make sure the membrane is set straight (the skew causes rattles.
⚠️ Attention, if the humidifier smells of burning after cleaning, immediately disconnect it from the network, which is a sign of damage to the control board!
If the problem is not solved, contact the service center Xiaomi. In most cases, breakdowns after cleaning are associated with damage to the membrane or oxidation of contacts (for example, if water hit the board).
