Regular maintenance of climate control equipment is the key to the health of all family members. The air humidifiers made by Xiaomi have proven to be reliable and effective devices, but they require periodic cleaning. In water tanks, bacteria multiply rapidly, and scale settles on parts, which can lead to unpleasant odors and reduced productivity.
Many users ignore the need to care until the appliance stops working properly or starts to make strange sounds. However, preventive cleaning takes only 15-20 minutes and allows you to extend the life of the device for years. In this article, we will discuss how to properly wash the humidifier series Mi Smart Antibacterial Humidifier, Smartmi and classic models with cartridges.
Special attention should be paid to the materials you plan to use to remove contaminants. Aggressive chemistry can damage plastic elements or the membrane, so it is important to strictly follow proven methods.
Preparation for cleaning and necessary tools
Before you start water treatments, you need to prepare the workplace and tools. You will need a sink or basin with warm water, a soft sponge for washing dishes (necessarily with a clean, non-greasy side), and cotton swabs for hard-to-reach places.
You can only wash removable parts: the water tank, the water tray (if it is removable) and the tank capacity itself. Before starting the process, be sure to disconnect the device from the network and let it completely cool if it worked.
- 🧽 Soft sponge or microfiber for cleaning surfaces
- 🍋 Citric acid or vinegar for dissolving mineral deposits
- 🧴 Disinfectant (optional) for treatment against bacteria
- 👕 Dry towel for drying out parts
⚠️ Warning: Never use abrasive powders, hard brushes or brushes with metal bristles.They can scratch the plastic and damage the sensitive ultrasonic membrane, which will lead to irreversible breakage.
If you use high-stringency tap water, plaque will form faster, so it makes sense to buy distilled water or use softener filters if your Xiaomi humidifier model supports installation, which will greatly simplify the maintenance process in the future.
Disassembly of the device and removal of filters
The first step of cleaning is to disassemble the water properly. Most Xiaomi humidifiers are modular. Remove the top cover, then remove the water tank. If your model has a water softening cartridge or evaporation filter, you need to take them out before you start washing.
Cartridge filters (usually yellow or gray) should not be washed with chemicals, should be thoroughly washed under a stream of cold water to remove surface dirt, and should the cartridge have been used up (usually for 2-3 months), it should be replaced with a new one, as it could accumulate harmful bacteria.
The main tank is removed from the stand. In some models, such as the Mi Smart Antibacterial Humidifier Pro, the water tray is also removable. Carefully lift it to access the bottom of the tank and the ultrasonic membrane. Be careful with the water level sensor wires if they are connected to the removable part.
- 💧 Remove the cover and remove all removable elements
- 🚿 Wash the filters with cold water without detergents
- 🔌 Make sure the electronics base is dry before installing the tank
What to do if the filter smells damp?
Scaling removal from the ultrasonic membrane
The most critical part of the maintenance is cleaning the ultrasonic membrane, which is where, as well as the walls of the tray, the most rapid white lime plaque is formed, which reduces the efficiency of vaporization and can cause the emitter to break down, and a citric acid solution is best for removing it.
Prepare the solution at the rate of 2-3 teaspoons of citric acid per 1 liter of warm water. Pour the solution into the water tray so that it covers the membrane and the bottom of the walls. Leave the device in this state for 30 to 60 minutes. The acid will react with the calcium salts and soften them.
Unlike vinegar, citric acid does not leave a sharp smell, which then weathers out of the plastic for a long time, so it is preferable for Xiaomi household appliances.
After soaking, gently wipe the membrane with the soft side of the sponge. White plaque should be easy to remove. If there are stains left, repeat the procedure. Under no circumstances do not pick the membrane with a knife, screwdriver or hard brush - this is a thin ceramic element that is easily broken by mechanical action.

Disinfection of the tank and elimination of odor
Even if the tank is visually clean, microorganisms that cause unpleasant odors and potentially harmful to the airways can multiply inside, a weak solution of chlorhexidine or special tablets to clean humidifiers can be used to disinfect, and soaking soda in a solution is also effective.
Pour the prepared disinfectant into the main tank, close the lid and shake the device well so that the liquid washes all the inner walls. Leave for 15-20 minutes. After that, thoroughly rinse the tank several times with running water to remove the residue of the chemical.
Pay special attention to the vapor opening and the internal channels. Often that's where the mucus accumulates. Use a long brush for bottles or wands of coiled cotton to clear hard-to-reach areas. Make sure there are no villi left inside of cotton candy or sponge.
| Type of pollution | Recommended remedy | Time of exposure | Frequency of processing |
|---|---|---|---|
| Lime plaque (scum) | Citric acid / Anticalcine | 30-60 minutes | Every 1-2 weeks |
| Bacteria and mold | Chlorhexidine / Soda / Tablets | 15-20 minutes | Once a month |
| Fatty plaque (kitchen) | Weak soap solution | 5-10 minutes | As it comes along |
⚠️ Note: It is strictly forbidden to pour disinfectants directly into a working humidifier, unless it is special cartridge disinfectants that come with the kit. Aggressive chemistry can damage the internal seals and membrane.
Drying and assembling of moisturiser
After all the water treatments, it's critical to let all the parts dry completely. The residual moisture in an enclosed space is the perfect medium for mold to develop. Spread the washed elements on a clean towel in a well-ventilated place.
Make sure not only the outside of the plastic is dry, but the inner corners as well as the area around the membrane.Do not use a hair dryer to speed up the process, as hot air can warp the thin plastic elements of the case.
When all the parts are dry, reassemble the humidifier in reverse order. Set the filters (if they are reused), insert the tray, set the tank on the base. Before first turning on after cleaning, it is recommended to pour clean water, turn on the appliance for 5-10 minutes, and then drain this water to wash possible residues of cleaning products from the system.
💡
For long-term storage (for example, in summer), dry the humidifier completely and put it in a box. Do not store the device with residual water inside - this is guaranteed to lead to mold and an unpleasant smell that is difficult to get rid of.
Frequent errors in service
Users often make mistakes that shorten the life of the device. One of the most common is the use of hot water to refuel. Xiaomi's ultrasonic humidifiers are designed for cold water. Hot water can damage sensors and speed up scale formation.
Another mistake is ignoring filter replacements, and even if the cartridge looks whole, its sorption capacity eventually declines, and it stops protecting the membrane from stiffening salts, and regularly check the condition of the consumables through the Mi Home app or visually.
Also, you should not add essential oils to the water if the model does not have a special compartment for flavoring. The oils dissolve the plastic of the tank and clog the pores of the membrane, disabling the device. For flavoring, use only the capsules intended for this purpose or external aroma blocks.
- 🚫 Do not use hot water from the tap.
- 📅 Don’t ignore the schedule for replacing filter elements.
- 🌿 Do not pour essential oils directly into the water without a special compartment.
💡
Keeping clean intervals and using the right remedies (citric acid instead of aggressive chemistry) is the key to a long and quiet operation of your Xiaomi moisturizer.
