How to Clean Xiaomi Air Humidifier: Step-by-step

Xiaomi's humidifier is not just a gadget, it's an important element of the microclimate in your home. It helps to combat dry air, especially during the heating season or in hot regions. However, like any device that works with water, the humidifier requires regular maintenance. Without proper cleaning inside the tank and heating elements, scale, mold and bacteria can accumulate, which not only spoil the device, but also enter the air, negatively affecting health.

Many users face problems: the humidifier starts to float poorly, emits an unpleasant smell or stops turning on altogether. Most often, the reason lies in late cleaning. In this article, we will discuss how to properly clean the Xiaomi humidifier (including popular models Smartmi Air Humidifier, Mi Air Humidifier, Xiaomi Smartmi Evaporative Humidifier and others), which tools to use and what to do categorically not to do.

Why Xiaomi Humidifier Should Be Cleaned Regularly

The water we put in the humidifier contains minerals, salts and microorganisms, and when the liquid evaporates, all these substances settle on the inside of the device, and over time, this leads to:

• 🧂 Scale formation is especially important in regions with hard water, and white coating clogs filters and reduces productivity.
• 🦠 Bacteria and mold multiply, and a moist environment is ideal for their growth, and it can cause bad smells and even allergic reactions.
• ⚡ Breakdown of the ultrasonic membrane – in models with ultrasonic spraying (for example, Mi Air Humidifier 2), the plaque on the membrane reduces its effectiveness.
• 🔥 Overheating and failure – if the heating element (in steam humidifiers) is covered with scale, this can lead to short circuit.

Xiaomi recommends cleaning the humidifier at least once a week for daily use. If you notice the first signs of contamination (turbid water, smell, vapor decrease), the procedure should be carried out immediately.

Especially careful is the model with built-in hygrostat (for example, Smartmi Air Humidifier 2). Even if the device itself regulates the humidity level, this does not mean that it self-cleans.

What Xiaomi Humidifiers Need Special Care

Xiaomi’s range of humidifiers is diverse, and each model has its own cleaning features, here’s a quick overview of the most popular devices and their “weaknesses”:

Models with antibacterial functions (such as the Mi Smart Antibacterial Humidifier) are less susceptible to mold formation, but this does not mean that they do not need to be cleaned. The UV lamp only kills bacteria during operation, and plaque and scale still accumulate.

If you have an evaporative humidifier (such as a Smartmi Evaporative), you should focus on filter discs, which over time become clogged with mineral deposits and require replacement or thorough washing.

💡

Always disconnect the humidifier from the mains before cleaning and drain the remaining water. Even if the device is switched off with a button, some models still have voltage on the board.

What can and can not clean the Xiaomi moisturizer

The choice of cleaning product depends on the type of contamination and the material of the humidifier.Most Xiaomi models have a plastic case and a tank, but some elements (such as an ultrasonic membrane) require delicate handling.

Authorized means:

• 🧼 Soft detergent (e.g. dishwashing fluid) – suitable for regular tank cleaning.
• 🍋 Citric acid or vinegar - effective against scale and lime plaque.
• 🧴 Special humidifier products (e.g. Xiaomi Mi Humidifier Cleaner) are the best option, as they do not damage the materials.
• 🧽 Soft sponge or brush - for mechanical cleaning of hard-to-reach places.

Prohibited means:

• ❌ Abrasive powders – scratch plastic and damage the ultrasonic membrane.
• ❌ Chlorine-containing bleach – can leave toxic fumes and spoil seals.
• ❌ Hard metal brushes – damage the internal coating of the tank.
• ❌ Acetone or solvents – destroy plastic and rubber parts.

In models with antibacterial coating (for example, Mi Smart Antibacterial Humidifier) you can not use vinegar or citric acid more than 1 time a month - this can damage the special coating of the tank.

If you're not sure which remedy to choose, consult your model's instructions. Xiaomi's manufacturer often lists recommended detergent formulations.

Step-by-step: how to clean the Xiaomi humidifier

The cleaning process can be divided into several steps, and we will look at the universal instructions that are suitable for most models, and also indicate the features for specific devices.

Disassembly of the device

First, unplug the humidifier and drain the water, then disassemble it into the main parts:

• Remove the top cover (in most models it unscrews counterclockwise).
• Remove the water tank.
• If your model has a removable filter (such as in the Smartmi Evaporative Humidifier), get it out.
• In ultrasonic models, carefully remove the base with the membrane (usually it is attached to the latches).

2. Cleaning the tank

The tank is the largest part of the humidifier that gets polluted most often.

1. Fill the tank with warm water (not boiling water!) and add detergent (1-2 dish-cap 1 litre).
2. Leave it on. 15-20 minutes to get soaked.
3. Use a soft sponge or brush to clean the walls. You can use cotton swabs for hard-to-reach areas.
4. Wash the tank thoroughly under running water.

If there is a strong lime plaque on the walls, use a solution of citric acid (2 spoonful 1 litre of water (1:1 Put the solution in the tank and leave it on. 30-60 minutes, then rinse.

Cleaning of the ultrasonic membrane (for appropriate models)

The ultrasonic membrane is the heart of a humidifier like Mi Air Humidifier, and it's very sensitive to mechanical damage, so you need to clean it carefully.

• Wet the cotton disc in a solution of citric acid or vinegar.
• Gently wipe the membrane without pressing.
• Don't use brushes or abrasives!
• Wash the membrane with clean water and dry in air.

Cleaning the filter (if any)

In evaporative humidifiers like Smartmi Evaporative Humidifier, there are filter discs that get clogged over time, and you can wash them under running water, but not more often. 2-3 After that, the filter loses its properties and requires replacement.

Some models (such as the Mi Smart Antibacterial Humidifier) have antibacterial cartridges installed, which can not be washed, only replaced according to the manufacturer's recommendations (usually once in a week). 2-3 month).

5. Disinfection of the humidifier

To kill bacteria and mold, disinfect:

• Pour into the tank a solution of hydrogen peroxide (3%) or a special disinfectant for humidifiers.
• Leave it on. 30-60 minute.
• Wash all parts thoroughly with running water.

For models with a UV lamp (for example, Mi Smart Antibacterial Humidifier), disinfection can be carried out less often, but it is still recommended to do this once every 2 weeks.

Assembly and inspection

After cleaning:

• Dry all parts in the air (do not use a hair dryer or battery!).
• Collect the humidifier in reverse order.
• Pour clean water (better distilled or filtered) and turn the device on.
• Check if there are any leaks or unusual sounds.

💡

Never turn on the humidifier immediately after cleaning with vinegar or citric acid. Residues of the product can damage the membrane or cause an unpleasant smell when first turned on.

How to remove mold and unpleasant smell from the humidifier

If your Xiaomi humidifier starts to smell damp or mold, it means that a colony of microorganisms has already developed inside, in which case, ordinary cleaning is not enough - you need to conduct deep disinfection.

Causes of smell:

• 💧 Stagnation of water – if you leave the water in the tank for a long time, it begins to bloom".
• 🌡️ High temperature - in a warm room, bacteria multiply faster.
• 🧴 Poor quality water – tap water contains organic impurities that serve as food for microbes.
• ⏳ Long-term use without cleaning – even if the external device looks clean, deposits can accumulate inside.

How to eliminate the smell:

1. Rinse the tank with a solution of vinegar and water (1:1) and leave for 1 hour. vinegar kills mold and neutralizes the smell.
2. Use hydrogen peroxide (3%) to disinfect, pour it into the tank for 30 minutes, then thoroughly rinse.
3. Dry all the details in the sun - ultraviolet light helps kill the remaining bacteria.
4. Replace water with distilled water – this will prevent the reappearance of mold.

If the smell is still there, even after cleaning, check the sealing gums, which are often where the mold accumulates, and you can clean them with a toothbrush soaked in a soda solution.

⚠️ Warning: If mold has penetrated deep into the plastic and is not removed mechanically, it is likely that the reservoir will have to be replaced.

How to extend the life of Xiaomi humidifier

Regular cleaning is only part of the care. To keep the humidifier lasting longer, follow these tips:

• 💧 Use distilled or filtered water – this will reduce the formation of scale.
• 🔄 Change the water daily, even if the humidifier is not working.Stagnant water is the main cause of mold.
• 🌡️ Store the device in a dry place - after use drain the water and dry the tank.
• 🔋 Do not leave the humidifier on at maximum power around the clock - this leads to overheating and rapid wear and tear.
• 🛠️ Periodically check the condition of the filters and membranes - timely replacement will save money on repairs.

If you live in a very hard water area, consider installing an additional water filter or buying demineralizing cartridges (e.g., Smartmi Air Humidifier 2).

Also worth paying attention to the modes of operation of the humidifier, for example, in models with hygrosate (Smartmi Air Humidifier). 2) You can set up automatic maintenance of humidity at the level 40-60%. This is the optimal range that does not create an excessive load on the device.

Frequent mistakes when cleaning Xiaomi moisturiser

Many users make mistakes that not only don't clean the device, but can also damage it.

• 🧹 Using hard brushes - this scratches the plastic and damages the membrane.
• 🔥 Boiling parts – high temperatures deform plastic and rubber seals.
• 🧼 The use of aggressive chemicals (such as Domestosa) – this can leave toxic residues.
• 💦 Non-drying before assembly - moisture inside leads to the rapid appearance of mold.
• ⚡ Turning on the device immediately after cleaning - residues of detergent can damage the membrane.

Another common mistake is ignoring the manufacturer's instructions, such as the Mi Smart Antibacterial Humidifier, which does not use vinegar to clean the UV lamp, as it can damage the coating. Always check the recommendations for your particular model.

⚠️ Warning: If the humidifier starts to work louder or stops producing steam, you may have damaged the ultrasonic membrane.In this case, contact the Xiaomi service center - self-repair can aggravate the problem.
