How to properly clean the air humidifier Xiaomi: from scale, mold and microbes

Xiaomi's air humidifier is an indispensable tool in the fight against dry air, especially during the heating season, but over time, the walls of the tank become white, mucus forms in the water, and an unpleasant smell begins to emanate from the device, which is a signal that the device urgently needs cleaning. Neglect of care not only shortens the life of the humidifier, but also turns it into a breeding ground of bacteria that then spreads around the room.

In this article, we will discuss how to clean a Xiaomi humidifier without risking damage to the plastic or membrane, and which popular tools (such as vinegar or bleach) can bring the device down, and how often to carry out preventive cleaning and what to do if mold starts in the water.

Why Xiaomi Humidifier Should Be Cleaned Regularly

The water you put in the tank contains minerals (calcium, magnesium) that, when evaporated, settle on the inner surfaces as white plaque, and if you ignore this problem, over time:

• 🔹 Performance drops – plaque narrows the holes for steam, and the device begins to work less efficiently.
• 🔹 There is a smell - bacteria multiply in standing water, which give the pair a characteristic "swamp" aroma.
• 🔹 Details deteriorate - scale clogs the ultrasonic membrane (in Xiaomi Smartmi models), which leads to its overheating and breakage.
• 🔹 Mold spores are common – black spots on the walls of the tank can cause allergies or breathing problems.

Hard water humidifiers (high in salts) are particularly rapidly contaminated, and in regions with such water, cleaning is 2-3 times more common, for example, in Moscow and St. Petersburg, the raid is formed after 3-5 days of continuous operation, while in Sochi or Krasnodar it is 7-10 days.

⚠️ Warning: If you notice that the vapor from the humidifier has turned green or black, turn it off immediately! This is a sign of active growth of mold or algae.

What can be cleaned humidifier Xiaomi: safe means

Not all household detergents are suitable for humidifier care, and aggressive chemicals (such as Domestos or White) corrode plastic and rubber seals, and their vapors can enter the air the next time they are turned on, and we tested several options and made a list of safe and effective remedies:

Important: For models Xiaomi Smartmi Air Humidifier 2 and newer categorically can not use abrasive means (soda, sand) – they scratch the ultrasonic membrane, which leads to its failure.

Step-by-step: how to clean the Xiaomi moisturiser from scale

Cleaning is best done in a well-ventilated room (for example, on the balcony) or in the bathroom with the hood on.

• 🧽 Soft sponge or microfiber cloth;
• 🍋 Citric acid or vinegar;
• 🧴 Toothbrush (for hard-to-reach places);
• 💦 Distilled water for rinsing.

Disconnect the device from the network and drain the water |

Disassemble the humidifier (remove the tank, filter, membrane if available)|

Soak the parts in a solution of citric acid for 30-60 minutes |

Clean the walls with a sponge, paying attention to the corners and holes |

Wash all parts with running water and dry |

Put the device together and pour fresh water|-->

Pay special attention to the ultrasonic membrane (if you have one in your model), which can not be rubbed with hard brushes or scraped with a knife, only carefully washed with water. In Xiaomi Mi Air Humidifier models, the membrane is located at the bottom of the tank and looks like a metal disc.

⚠️ Note: If after cleaning the humidifier began to make an unusual noise (cracking, whistling), then the membrane is damaged.

How to remove mold and black plaque in the humidifier

Mold occurs when the device has been idle with water inside for a long time or when unfiltered water with a high content of organics is used. Black spots not only spoil the view, but also dangerous to health - mold spores can cause allergies and asthma.

To remove mold:

1. Prepare the solution: 1 cup of hydrogen peroxide (3%) + 1 cup of water.
2. Pour it into a tank and leave it for 1-2 hours.
3. Carefully clean the walls with a toothbrush, paying attention to the seams and corners.
4. Wash the tank under running water and dry it in air (do not use a hair dryer!).

If the mold returned after a few days, it has penetrated deep into the plastic, in which case only complete disinfection with chlorhexidine (0.05% solution, sold in pharmacies), pour it into the tank for 30 minutes, then rinse with water. Chlorhexidine leaves no smell and is safe for plastic.

What can not clean the humidifier Xiaomi: dangerous mistakes

Some folk methods can permanently damage the device, and this is something you're absolutely forbidden to do:

• 🚫 Use abrasives (baking soda, sand, metal brushes) - they scratch the plastic and membrane.
• 🚫 Pour undiluted vinegar or citric acid – this corrodes the seals and can cause leakage.
• 🚫 Use chlorine or "White" - their vapors are toxic and remain in plastic for a long time.
• 🚫 Wash in a dishwasher - high temperatures warp parts.
• 🚫 Drying with a hair dryer or on a battery – this can melt plastic or damage electronic components.

Also, you should not use essential oils to flavor water — they settle on the membrane and clog it, reducing the life of the device. If you want a flavor, buy special capsules for humidifiers (for example, Xiaomi Mi Home Aroma Diffuser).

💡

To reduce scale, add 1-2 drops of table vinegar (1 liter) to the water, which will reduce the hardness of the water and prolong the time between cleanings. But remember to drain this solution after use!

How often should you clean the Xiaomi humidifier?

The frequency of purification depends on the hardness of the water and the intensity of use:

Determine that the device needs cleaning, can be according to the following signs:

• 🔍 On the walls of the tank appeared white or green plaque;
• 👃 The humidifier produces an unpleasant smell;
• 💧 The steam became less intense;
• 🔊 The device began to make noise louder than usual.

💡

If you use a humidifier in a nursery, you should clean 2 times more often - every 3-4 days, even if the device appears clean visually, this will prevent the reproduction of bacteria that are dangerous to children.

Care of Xiaomi moisturiser: pollution prevention

To lessen the resort to general cleaning, follow simple rules:

1. Use the right water, ideally distilled or bottled water labeled "baby food," boiled and settled at the very least.
2. Change the water daily, even if the humidifier is not working, and stagnant water is the main cause of bacteria.
3. Dry the tank after use – before removing the device, wipe the inner walls with a dry cloth and leave the tank open for 10-15 minutes.
4. Store in a dry place – if the humidifier is not used for more than a week, drain the water, rinse and dry all the parts.

For models with interchangeable filters (such as Xiaomi Smartmi Air Humidifier 2), remember to change the cartridges every 2-3 months. A clogged filter not only purifies the water worse, but also becomes a source of pollution.

⚠️ Attention: If you notice that the humidifier noise level has increased and the steam has become less intense, this may be a sign of fan contamination.In this case, disassemble the body (if instructed) and clean the fan blades with a brush or vacuum cleaner.
