How to wash the humidifier Xiaomi: full instructions with photos and tips from experts

Why cleaning Xiaomi moisturizer is not just about washing it with water

Xiaomi’s humidifier is one of the most popular gadgets for the home, but many users miss a key point: regular cleaning is as important as choosing a model or setting modes. Unlike a regular vacuum cleaner or lamp, the humidifier works with water — which means that it creates an ideal environment for bacteria to multiply, mold and build scale. If you limit yourself to only rinsing the tank once a month, you risk turning the device into a source of harmful fumes.

The manufacturer in the instructions for Mi Air Humidifier, Smartmi Evaporative or Xiaomi Deerma models indicates that it is necessary to clean every 3-7 days (depending on the hardness of the water and the intensity of use). But how to do it correctly? What products are safe for plastic and membranes? And why can the humidifier begin to smell or spray steam worse after washing? The answers are in this guide, compiled on the basis of official recommendations of Xiaomi and the experience of service centers.

We'll take it apart.

• 🔍 Step-by-step instructions for all models (including ultrasonic and evaporative models)
• 🧴 Allowed and prohibited means (vinegar, citric acid, chlorine - what can and what will kill the device)
• ⚠️ Typical errors that cause the humidifier to break or start to smell
• 📅 Care schedule depending on frequency of use

Preparation for cleaning: what you need and how to avoid breakage

Before you start washing, disconnect the humidifier from the network and drain the remaining water. This seems obvious, but every year Xiaomi service centers receive devices with a short circuit due to moisture entering the electronic unit. 2/Pro — Their humidity sensors are located close to the tank.

Gather the necessary tools and tools:

• 🧼 Soft sponge or microfiber cloth (abrasive brushes scratch plastic)
• 🧂 Citric acid or vinegar 9% (to remove scale)
• 🧴 Liquid soap or baby bottle product (no fragrances)
• 🪒 Toothbrush with soft bristles (for hard-to-reach places)
• 🚰 Distilled or filtered water (for rinsing)

Critical error: Never use chlorine, acetone or aggressive surfactants (such as Domestos or Belizena) to clean a Xiaomi humidifier. They destroy sealing gums and membranes, and leave toxic fumes that then enter the air. In 2023, Xiaomi even issued an official warning about this after a series of complaints about the breakdown of the Smartmi Evaporative Humidifier 2.

Step-by-step: how to wash Xiaomi moisturiser inside and out

The cleaning process depends on the type of device. Ultrasonic models (Mi Air Humidifier, Deerma Humidifier) require delicate handling of the membrane, and evaporative models (Smartmi Evaporative) require thorough drying of filters. Consider a universal algorithm suitable for most devices.

1. Cleaning the water tank

Pour warm water into the tank (temperature not higher than 40)°C) and add:

• 🍋 2 tablespoons of citric acid or
• 🥛 50 ml vinegar 9% per 1 liter of water.

Leave for 30 to 60 minutes, then rinse with a soft sponge. For stable scale, use a toothbrush, but without pressing.

2. Treatment of the base and the sprayer

The ultrasonic membrane (in Mi Air Humidifier models) is the most sensitive part. Rub it with a damp cloth without detergents. If there is white plaque on the membrane, carefully remove it with a cotton swab dipped in a weak vinegar solution (1:1 with water). Don't rub the membrane with dry cloth - this leads to microcracks.

For evaporative humidifiers (Smartmi):

• 🌿 Remove the filter and rinse it under running water.
• 🚫 Do not use detergents – they clog the filter pores.
• ☀️ Dry the filter in air (not in the microwave!).

Disinfection (if necessary)

If the humidifier smells, disinfect:

1. Pour into the tank solution: 1 h.spoon of hydrogen peroxide 3% per 1 liter of water.
2. Turn on the device for 10-15 minutes in maximum spray mode.
3. Pour the solution and rinse the tank 3-4 times with clean water.

💡

Xiaomi ultrasonic humidifiers can not be cleaned with hard brushes or abrasives - this damages the membrane and reduces the life of the device.

What can not wash the humidifier Xiaomi: a blacklist of funds

Some "folk" cleaning methods can not only damage the device, but also make it dangerous to health.

• ☠️ Chlorine-containing products ("White", "Domestos") - destroy plastic and leave toxic fumes.
• 🔥 Boiling water - deforms the tank and seals (especially in models with transparent plastic).
• 🧴 Aggressive detergents (for example, "mole" for pipes) - corrode membranes and filters.
• 🧂 Salt or soda in dry form – scratching the inner surfaces.
• 🛢️ Gasoline, acetone, solvents – even in small doses lead to cracks in plastic.

In 2022, Mi Community users complained massively about the Mi Air Humidifier Lite breakdowns after being cleaned by Mole, and the manufacturer confirmed that the warranty did not apply in such cases, as it was a violation of operating rules.

⚠️ Warning: If you've used illegal products, don't turn on the humidifier immediately after cleaning. Let it ventilate for 12 to 24 hours to vaporize the residue of the chemical.

How often to wash the humidifier: a schedule for different conditions

The frequency of cleaning depends on three factors:

1. The water is more stained, the more stained the water is.
2. Intensity of use (round the clock or periodically).
3. Type of device (ultrasonic require cleaning more often than evaporative).

If you notice at least one of these signs, clean up immediately:

• 🤢 Smell of dampness or mold when switched on.
• ☁️ White or black plaque on the inner walls.
• 💧 The volume of steam decreased with the same settings.
• 🔊 Extraneous sounds (bubbling, crackling) during work.

💡

If you use a humidifier in a nursery, clean it every 3 days — even if it looks clean on the outside. Children are more sensitive to bacteria in the air.

What to do if the Xiaomi humidifier after cleaning does not work

Sometimes, after washing, the device refuses to turn on, doesn't spray steam well, or makes an error, and here are the most common reasons and solutions.

⚠️ Note: If the Mi Air Humidifier humidifier shows an error after cleaning E1 or E2, This means a water sensor problem. Don't try to disassemble the device yourself, call the service.

If the Smartmi humidifier starts flashing red after washing, this may indicate:

• 🚰 Installation of the filter incorrectly (check if it is tightly inserted).
• 🔋 Low water level (even if the tank is full, the sensor could become contaminated).
• 🔧 Firmware failure (try resetting via Mi Home app).

How to extend the life of a Xiaomi moisturizer: tips from service centers

The average life of Xiaomi humidifiers is 3-5 years, but with proper care, it can last longer.

• 💧 Use distilled or filtered water – this reduces scale formation by 70%.
• ☀️ Dry the device after each use – a wet environment accelerates mold growth.
• 🔄 Change the filters in the evaporation models every 2-3 months (even if they look clean on the outside).
• 📱 Update your firmware through Mi Home – newer versions often improve self-cleaning algorithms.
• 🏠 Store the humidifier in a dry place covered with a cloth from dust.

In Mi Air Humidifier 2 and later, there is a self-cleaning feature, which you turn on once a week, and the device will wash the tank with hot steam, but this does not cancel manual cleaning!

💡

The use of aromatic additives (such as essential oils) in Xiaomi humidifiers voids the warranty: The oils clog membranes and filters, and their vapors can be toxic when heated.
