How to properly wash the air humidifier Xiaomi: step-by-step instructions and care secrets

Xiaomi's humidifier is an indispensable tool for dry air control, but even the most advanced technology requires regular maintenance. If you notice a white plaque on the walls of the tank, an unpleasant odor when working, or black spots inside the tank, it's a signal that the device needs to be cleaned urgently. Neglecting hygiene not only shortens the life of the device, but also turns it into a breeding ground of bacteria that are then sprayed around the room.

In this article, we will discuss 7 Effective ways to wash Xiaomi humidifier (including Smartmi Air Humidifier models) 2/3, Mi Air Humidifier Pro and others, which are safe for plastics and membranes and which can harm you, and how to eliminate persistent odors and prevent re-contamination, all of which have been tested on real devices and don't require professional skills.

Why Xiaomi Humidifier Needs Cleaning: 3 Top Reasons

Many users only clean the appliance when it starts to work poorly or smell bad, and in fact, you need to clean the humidifier regularly, even if it looks perfect on the outside.

• 🧫 Bacteria and mold reproduction: Water, especially if it's not distilled, contains microorganisms that settle on the walls of the tank and filter, and when sprayed, they enter the air and can cause allergies or respiratory problems.
• ⚪ Scale and mineral deposits. If you use tap water, the calcium and magnesium salts form a white coating that clogs the sprayer over time and reduces productivity.
• 🤧 "Dirty moisturiser syndrome, which is a condition where the device causes harm instead of good by spraying contaminated water, symptoms such as coughing, irritation of the mucous membranes, headache after switching on the device.

Xiaomi recommends cleaning the humidifier every 3-5 days with daily use, if the device works periodically, weekly processing is enough, but even with a schedule, deep cleaning is sometimes required with disassembly, especially if the device has been standing without water for a long time.

⚠️ Warning: Never use abrasive sponges or metal brushes to clean your Xiaomi moisturiser, which scratch the antibacterial coating of the tank (if your model has one), which accelerates the growth of mold in the future.

What can be cleaned humidifier Xiaomi: safe and prohibited means

Not all household detergents are suitable for humidifiers, such as chlorine-based bleachers that can damage plastic and aggressive acids that can destroy the membrane of ultrasonic models.

Prohibited means:

• 🚫 Whiteness and chlorine – destroy plastic, leave toxic fumes.
• 🚫 Concentrated acids (salt, sulfur) - damage the membrane and seals.
• 🚫 Hard brushes – scratch the surface, creating microcracks for bacteria.
• 🚫 Aromatic oils – leave a film that clogs the sprayer.

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

Before cleaning, disconnect the device from the network and drain the remaining water. Disassemble the humidifier according to the instructions (usually remove the top cover, remove the filter and membrane if it is removable).

Disconnect from the socket and drain water|

Disassemble on removable parts (tank, cover, filter)|

Prepare products (citric acid / vinegar) and a soft sponge|

Wear gloves (when working with vinegar or peroxide)-->

1. Scale tank cleaning

To remove the white plaque:

1. Pour warm water into the tank (temperature not higher than 40)°C to prevent deformation of plastic).
2. Add 2 tbsp of citric acid or 100 ml of vinegar per 1 liter of water.
3. Leave for 1-2 hours (with a strong scale - at night).
4. Gently rub the walls with a soft sponge (for example, for washing dishes).
5. Wash thoroughly with running water 3-4 times.

2. Disinfection from mold and bacteria

If there are black dots inside the tank or on the filter:

1. Prepare the solution: 1 part hydrogen peroxide (3%) to 1 part water.
2. Apply to contaminated areas with a sponge or pour into the tank for 15-20 minutes.
3. For hard-to-reach places, use a cotton swab dipped in solution.
4. Wash with running water and dry in the air (do not use a hair dryer!).

3. Membrane cleaning (for ultrasonic models)

The membrane is the most delicate element, and it can't be rubbed or soaked in aggressive solutions.

1. Remove the membrane according to the instructions (usually located at the bottom of the device).
2. Rinse under cool running water without pressure.
3. If there is a plaque, place the membrane in a weak solution of citric acid (1 tsp. per 1 liter of water) for 5-10 minutes.
4. Rinse and dry on a napkin away from direct sunlight.

💡

If the membrane has become less elastic or has changed color, it should be replaced. In Xiaomi Smartmi models, the membrane is designed for 2-3 years of intensive use.

4. Cleaning the filter

Filters in Xiaomi humidifiers come in two types:

• 🔄 Replaceable (e.g. Mi Air Humidifier Pro) – rinse underwater and dry. Change every 3-6 months.
• 🧽 Permanent (in most models) - cleaned the same way as the tank, but without soaking. Use a soft brush (for example, a toothbrush).

5. Eliminating the unpleasant odor

If there is a stale smell after cleaning:

1. Prepare the solution: 1 tbsp. l. soda per 1 liter of water.
2. Pour in the tank and leave for 30 minutes.
3. Wash and fill with pure water with 2-3 drops of tea tree essential oil (if the instructions allow).
4. Turn on the device for 10-15 minutes in the ventilated room.

⚠️ Note: Do not use essential oils in aromadiffuser humidifiers (e.g. Smartmi Air Humidifier) 2S). Oils can clog special channels for flavoring, which will lead to breakage.

How to clean Xiaomi humidifier from green plaque (algae)

Green coating is algae that comes from not changing water for long periods of time or using inappropriate additives (like aromatic oils) that are not as dangerous as mold, but also require urgent removal.

1. Pour the water and rinse the tank with running water.
2. Prepare the solution: 100 ml of vinegar + 1 tsp salt per 1 litre of water.
3. Pour it in the tank and leave it for 1 hour. The salt will increase the effect of vinegar against algae.
4. Gently rub the walls with a silicone spatula (not metal!).
5. Rinse 3-4 times, then pour clean water with 1 tbsp. l. peroxide for 10 minutes for disinfection.

If the algae appeared on the membrane:

• 🚿 Wash it under running water.
• 🍋 Wipe with a cotton disc soaked in a solution of citric acid (1 tsp per glass of water).
• ⏳ Let it dry in the air for at least 2 hours.

Cleaning Xiaomi moisturiser with special tablets

If you don't want to mess with home remedies, you can use special humidifier pills. They not only clean, they disinfect, and they often contain flavors. Popular brands: Top House, Bork, Philips.

Instructions:

1. Pour warm water into the tank (the volume is indicated on the package of tablets).
2. Add 1-2 tablets (dosage depends on the volume of the tank).
3. Leave for 30-60 minutes (time is indicated in the instructions for tablets).
4. Wash the tank and other parts with running water.
5. Please dry before the next use.

Pros of pills:

• ✅ Quickly and effortlessly.
• ✅ Suitable for regular cleaning.
• ✅ Often contain antibacterial components.

Cons:

• ❌ More expensive than home funds.
• ❌ Not everyone is suitable for ultrasonic humidifiers (read the instructions!).

💡

Special pills are the best choice for weekly preventive cleanings, which are milder than vinegar or citric acid and do not damage plastic when used regularly.

TOP-5 Mistakes in cleaning Xiaomi moisturiser (and how to avoid them)

Even experienced users sometimes make mistakes that cause the humidifier to break or wear it prematurely.

1. Using boiling water to clean it, hot water deforms the plastic and can damage the membrane, maximum temperature is 40.°C.
2. Cleaning with metal objects (knives, forks, hard brushes) that scratch the surface, and dirt accumulates in microcracks faster.
3. Ignoring the filter. Many people only clean the tank, forgetting about the filter, which eventually clogs and becomes a source of smell.
4. Storage with water inside. If the humidifier is not used, the water must be drained and dried, otherwise the mold will appear in 2-3 days.
5. Using undiluted vinegar or peroxide, concentrated solutions damage plastic and rubber seals.

Another common mistake is to dry the humidifier incorrectly, and some users collect the humidifier immediately after washing it without waiting for it to dry out completely, and this leads to:

• 🌑 The appearance of mold in hard-to-reach places.
• ⚡ Short circuit (if moisture gets on electronic components).
• 💨 Reduced membrane life (in ultrasonic models).

💡

To speed up drying, place the humidifier in a well-ventilated place (like a balcony) or use a fan at minimum power. Don't dry in direct sunlight - UV radiation destroys plastic!

How often should you clean the Xiaomi moisturiser: a care schedule

The frequency of cleaning depends on the intensity of use and the quality of the water.

If you use distilled or filtered water, you can clean less often, and when you use tap water (especially hard water), you can clean more often.
