Regular maintenance of appliances is not just a matter of aesthetics, but a necessity for the health of households. Humidants such as the popular Xiaomi Mi Smart line, in the process of operation, pass through huge volumes of water, which often contains impurities and mineral salts. Over time, white plaque forms inside the tank, and bacteria and mold can multiply in hard-to-reach places, which are then sprayed into the atmosphere.
Smart device owners often neglect deep cleaning, relying on built-in sensors or visual water purity. However, ignoring the care of the ultrasonic membrane and the inner walls of the tank leads to reduced performance and unpleasant smell. For your Mi Smart Humidifier to work silently and efficiently, you need to know the right sequence of actions when maintaining it.
In this article, we will discuss the process of dismantling, selecting safe cleaning products and assembling the device. You will learn how to avoid common errors that can lead to breakage of electronics or damage to plastic elements of the case.
Preparation for maintenance and safety
Before any manipulation of the appliances, it is necessary to ensure the safety of the process. The first step should always be to completely disconnect the device from the electrical network. Do not rely on software shutdown via the Mi Home application, since physical contact with water requires an absolute guarantee of no current in the circuit.
Prepare the workspace: put a towel or a twig over the table so you don't damage the surface or lose small parts. You need access to a sink with running water. You need to get the tools you need in advance so you don't get distracted.
⚠️ Warning: Never immerse the base of the electronics appliance in water, only a removable tank and plastic elements that do not contain electrical contacts are to be washed.
For good cleaning, you'll need soft sponges that don't scratch plastic, and cleaning products. The use of abrasive powders or hard brushes is strictly prohibited, as micro-scratches will be the perfect environment for bacteria to settle in the future. Also prepare a container for soaking parts if the plaque is too strong.
Necessary tools and cleaning products
Choosing a cleaning product is a critical step, and the market offers a lot of chemicals, but not everyone is in contact with the air you breathe, and aggressive chlorine solutions can damage plastic and leave toxic traces.
The best solution for removing mineral plaque (limestone) is citric acid or table vinegar, which effectively dissolves salt deposits without damaging the structure of the plastic and membrane.
- 🧼 Citric acid (solution) 20-30 g 1 liter of warm water - the best remedy for scale.
- 🌿 Table vinegar 9% – alternative to citric acid, requires careful rinsing due to smell.
- 🧽 Soft sponge or fabric made of microfiber - for mechanical cleaning of walls.
- 🪥 Old toothbrush - for cleaning hard-to-reach corners and membrane mesh.
It is important to note that using hot water to prepare the solution speeds up the reaction, but the temperature should not exceed 40-50 degrees, so as not to deform the plastic parts of the tank.
The order of disassembly of the Xiaomi moisturiser
Design of humidifiers Xiaomi Mi Smart (models) CJJSQ01ZM, JSQ01CA, JSQ3 And others, it's modular, it's easy to maintain, but it requires care, and it starts with the top of the tank (water tank) being detached from the base where the evaporator is located.
Turn the tank upside down only after making sure the lid is tightly closed so that residual water does not fall on the floor or into the fragrance compartment (if it is located on top). Pour the water residue from the tank and base. Carefully inspect the bottom of the tank: there may be a floating filter that also requires attention.
☑️ Disassembly stages
The base of the device, where the ultrasonic membrane is located, also needs to be inspected. Water from the tank may have leaked there during operation. Carefully wipe the bottom of the base with a dry cloth before cleaning, so that water does not enter the body through the vents. Remove all removable plastic inserts inside the base bowl.
Scaling removal and tank cleaning
The main problem with humidifiers is the white plaque on the walls of the tank and the heating elements (if any) or the membrane, which is made up of calcium and magnesium salts in tap water, and it's difficult and risky to mechanically wipe it off, so you use a soaking method.
Pour a prepared warm solution of citric acid into the tank, the liquid should cover all areas with plaque, leave the device in this form for 30-60 minutes, during which time the acid will react with the salts, soften them and allow you to easily remove the residues with a sponge.
| Type of pollution | Recommended remedy | Time of exposure | Tool. |
|---|---|---|---|
| Light white plaque | Citric acid solution | 30 minutes. | Soft sponge |
| Strong scale | Concentrated acid solution | 1-2 hours | Toothbrush |
| Mucus on the walls | Vinegar solution or peroxide | 40 minutes. | Ershik |
| Mold | Specialized pills | Instructions. | A bristlebrush |
After soaking, thoroughly rub the walls of the tank. Pay special attention to the neck and the inside of the lid, where dirt often accumulates. Wash the tank with plenty of clean running water to completely remove the residues of cleaning agent and dissolved salts.

Treatment of ultrasonic membrane and base
The most important element of the humidifier is the ultrasonic membrane, which is located in the center of the base, which vibrates at a high frequency, breaking water into a mist. On the surface of the membrane and around it, a dense layer of scale often forms, which reduces the efficiency of vaporization and can cause overheating.
To clean the membrane, use a soft toothbrush soaked in a solution of citric acid, and the movements should be light, circular, and it is strictly forbidden to rub the membrane with metal objects, a knife or the hard side of the sponge, since it is very easy to damage it and it is expensive to replace it.
⚠️ Warning: Water should not leak into technical holes around the membrane, where water level sensors and contacts are located.
After cleaning the membrane, make sure to wipe the base dry with soft cloth. Make sure that there are no drops of water left in the sensor recesses. If the model is equipped with a water softening filter (cartridge), check its condition. If it becomes dark or loose, it should be replaced, since cleaning old cartridges is inefficient.
💡
Use distilled or filtered water to refill the humidifier, which will significantly reduce the rate of scale formation and reduce the frequency of necessary cleanings.
Disinfection and elimination of odors
Even if the device is visually clean, there may be bacteria and mold spores that are invisible to the eye, especially if the humidifier has been idle for some time with the water inside, or you can use a hydrogen peroxide solution (3%) or special antiseptics for household appliances to disinfect.
Pour the disinfectant into the tank, collect the humidifier and turn it on for 10-15 minutes in maximum power mode, previously removing the lid from the vapor opening. This will allow the antiseptic vapors to pass through all the internal channels and tubes of the device, disinfecting them.
- 🦠 Regular disinfection (every 2 weeks) prevents the appearance of the smell of "rawness".
- 🍋 Adding a couple of drops of essential oil (only if there is a special compartment) helps to refresh the air, but does not disinfect the device itself.
- 🌬️ After the disinfection procedure, be sure to rinse the tank with clean water and let the device work on a clean couple for another 10 minutes.
If the smell is still there after cleaning, it may have been absorbed into the plastic seals, which can help to keep the parts clean in the shade, and direct sunlight can make the plastic brittle.
Drying and assembly of the device
The final step is to dry and assemble properly, and all the parts that are washed must be completely dry before you pour the water again, and the moisture in an enclosed space without air circulation is the perfect environment for microbial growth.
Wipe all the elements with a lilaless cloth and leave them disassembled for 1-2 hours at room temperature. Make sure there are no drops of water left inside the tank. Collect the humidifier in reverse order: set the base, check the density of the membrane knot, then install the tank.
💡
Complete drying of all parts before storage or assembly is the main guarantee of the absence of mold and unpleasant odor at the next inclusion.
Once assembled, pour fresh water and turn on the device, which can make unusual sounds for the first few minutes of operation if there is air or microparticles of cleaning product in the system, which is normal, and after a short time, the work stabilizes.
Frequency of service and prevention
For Xiaomi Mi Smart Humidifier to last, it is important to follow a maintenance schedule. The frequency of cleaning depends on the hardness of the water in your area and the intensity of the device use. On average, a full acid cleaning is recommended every 1-2 weeks.
It is recommended to change the water in the tank daily, without leaving the old water "for tomorrow". Stagnant water blooms quickly. Check the condition of the softener filter once a month and change it as needed (usually every 1-2 months).
Compliance with simple rules of operation will avoid expensive repairs and keep your family healthy. A clean humidifier is the key to well-being and the absence of allergic reactions to dust and bacteria.
