Regular maintenance of climate engineering is not just a matter of aesthetics, but a necessity for the health of the household. If you are wondering how to clean a shaomi humidifier, you have encountered a white coating on furniture or smelled a bad smell of steam. Ultrasonic models of this brand, such as Smartmi Evaporative Humidifier or Mijia Pure Smart, require a special approach to the care of the membrane and tank.
Unlike traditional steam evaporators, it uses high-frequency vibrations that break water down into tiny droplets, which is why water quality and clean interior surfaces are critical, and ignoring cleaning procedures results in biofilms that are then sprayed throughout the room with moisture.
In this article, we will discuss safe methods of scale removal and disinfection that will not damage sensitive electronics and ultrasonic membranes. You will learn which tools are really effective and which can irrevocably spoil the device. Proper care will extend the life of the gadget and ensure the clean air in your home.
Why it is important to wash your air humidifier regularly
The main problem with all ultrasonic humidifiers is hard water, and even if you use filtered water, it still has mineral salts, and over time, they settle at the bottom of the tank, the heating elements (if any), and most importantly, on the ultrasonic membrane, which reduces the efficiency of vaporization and can cause the device to overheat.
But minerals are not the only threat: the humid, warm environment inside the tank is ideal for bacteria and mold to grow; if you don't disinfect at least once a week, the colonies of microorganisms start to grow, and when you turn on the device, mold spores and bacteria are released into the air, which can cause allergies or asthma.
⚠️ Attention: Using a dirty moisturiser can cause "wet room syndrome", manifested by coughing, headache and irritation of mucous membranes.
In addition, the contaminated membrane begins to work with increased load, which leads to rapid wear of the piezoelectric element and failure of the main control board, regular washing allows you to maintain the manufacturer's declared performance and reduces energy consumption.
Preparation for cleaning: disassembly and safety
Before you start washing the shaomi humidifier, you need to properly prepare the device. The first step should always be to disconnect the device from the power grid. Under no circumstances do you try to disassemble or wash the device while it is connected to the outlet, even if you are just rinsing the tank.
The process of disassembly in Xiaomi models is usually intuitive, but has its own nuances: the upper water tank is removed separately from the base with electronics. In some models, such as the Xiaomi Mi Humidifier Pro, you need to remove the top cover to access the insides of the tank.
☑️ Preparation for cleaning
It's important to carefully handle the floating valve and float, if you have one in your model, and these elements are responsible for controlling water levels and preventing overflows, and the loss or damage of small parts can lead to water leaking to the floor or into the base of the device itself.
If your humidifier has a demineralization cartridge (usually a white cylinder inside the tank), it must be removed before cleaning with aggressive means. The cartridge contains resins that can react with acid or vinegar, losing their properties.
Scaling and white plaque removal
The white plaque that you see on the bottom of a tank or on surrounding objects is calcium and magnesium. To remove it, mechanical sponge cleaning is often not enough, especially if the layer is old. The most effective and safest remedy is citric acid.
To prepare the solution, dilute 20-30 grams of citric acid in a liter of warm water. Pour this solution into a tank and leave it for 30-60 minutes. The acid will gently dissolve solid deposits without damaging the plastic. After that, thoroughly rub the walls with a soft brush or sponge.
| Cleaning device | Concentration | Time of exposure | Anti-scale effectiveness |
|---|---|---|---|
| Citric acid | 20-30g per 1 l | 30-60 minutes. | Tall. |
| Table cider vinegar (9%) | 1 part to 3 parts water | 1-2 hours | Medium/High |
| Special pills | 1 pc per tank | Instructions. | Very high. |
| Baking soda | Porridge with water | 15-20 minutes | Low (for fat) |
Table cider vinegar is an alternative to citric acid, but it has a pungent odor that takes a long time to weather from the plastic. If you use vinegar, make sure that the room is well ventilated, and after cleaning, rinse the tank several times with clean water.

Disinfection and control of bacteria
After removing the mineral deposits, the disinfection stage begins. Even if the device appears clean, microorganisms can remain invisible to the eye on the walls. For Xiaomi ultrasonic models, it is important to use products that do not leave toxic traces.
One of the most affordable and efficient ways is to treat hydrogen peroxide, pour a 3% solution of hydrogen peroxide (you can dilute it with 1:1) into the tank and leave it for 30 minutes, and it kills bacteria perfectly, and it breaks down into safe water and oxygen.
You can also use special disinfectant tablets for humidifiers, which are sold in household appliance stores, they are designed specifically for climate engineering and do not contain components harmful to inhalation, dissolve the tablet in water according to the instructions on the package and treat all surfaces.
⚠️ Attention: It is strictly forbidden to use chlorine-containing products (for example, "White") to clean the humidifier. Chlorine vapors, entering the lungs, can cause serious poisoning.
Don't forget the hard-to-reach areas. Use a soft toothbrush to clean out the corners of the tank, around the vapor openings and under the rubber seals, and these are the areas where mucus is most commonly formed.
Cleaning of the ultrasonic membrane
The most important and delicate element of the humidifier is the ultrasonic membrane, located at the bottom of the base (or in the removable module, depending on the model), which generates fog, and if the membrane forms a plaque, the device stops giving steam or starts to work with a lot of noise.
Cleaning the membrane is extremely careful. Abrasive sponges, metal brushes and brushes are strictly prohibited here - they will instantly damage a thin ceramic or metal layer. To clean, use a cotton swab dipped in a solution of citric acid.
Carefully wipe the surface of the membrane in circular motions, removing the white plaque. Don't press hard. If the plaque is old, you can put a cotton cotton disc moistened in a cleaning solution on the membrane for 10-15 minutes, and then gently remove the softened deposits.
💡
If the humidifier is buzzing after cleaning, but the pair is not, check if the pile is left from the cotton swab on the membrane.
After cleaning, be sure to wipe the base with a wet and then dry cloth.The water should not get into the vents or electronic contacts.Be sure all parts are completely dry before assembly.
Caring for the filter and demineralization cartridge
Xiaomi models often use demineralization cartridges filled with a special resin, which serve to soften water and prevent white plaque, and typically last 1-3 months depending on the hardness of the water.
You can't wash the cartridge itself, it's going to destroy its properties, but the cartridge case and the net it's being inserted into must be washed regularly under running water, and this will prevent silting and deterioration of the water passage.
In evaporative models (such as Smartmi Evaporative Humidifier 2), a replaceable filter element is used, it cannot be washed with water with detergents, only a light rinse with clean water without friction is allowed to remove dust, and you can not wipe this filter, the fibers will break down.
If the filter has become unpleasant, has turned yellow or has become covered with mold, it must be replaced, and the use of an old filter negates the work of the humidifier and pollutes the air.
💡
Replacing the demineralization cartridge or evaporative filter is a mandatory procedure that cannot be ignored, otherwise the efficiency of the device will drop to zero.
Drying and storage of the device
Proper drying is the final stage of maintenance. You can't collect the humidifier right after washing, and moisture residues in the hidden cavities can cause a musty smell the next time you turn on.
Spread out all removable parts on a clean towel in a well-ventilated place. Let them dry naturally for a few hours. Don't use a dryer to dry plastic parts, as hot air can warp the body.
If you plan not to use the humidifier for a long time (for example, in summer), be sure to completely dry it before cleaning in the closet. Store the device in a disassembled form, with an open lid, so that mold does not start inside.
Packing a wet appliance in a box or bag is strictly forbidden, and this is guaranteed to lead to the emergence of a fungus that will be very difficult to remove before next season.
