1.Preparation for cleaning: what will be needed and safety measures

Before you start cleaning, make sure you have everything you need on hand, and improperly selected tools or products can damage the plastic or antibacterial coating of the tank.

• 🧼 Soft sponge or microfiber cloth (abrasive brushes scratch the surface!).

⚠️ Warning: Never use chlorine-containing products (such as "White"), aggressive acids (acetic essence) or hard metal brushes to clean Xiaomi Mi Smart Antibacterial Humidifier. This destroys the antibacterial coating and can lead to water leakage due to damage to seals.

Before you start, be sure to disconnect the device from the network and drain the remaining water. If the humidifier has not been cleaned for a long time, the water inside may have an unpleasant odor - this is a sign of bacterial reproduction in the reservoir, in which case you will need a deep disinfection, which we will talk about in one of the following sections.

2. Disassembly of the humidifier: a step-by-step guide with a photo

The Xiaomi Mi Smart Antibacterial Humidifier is designed with a few “secret” latches that aren’t obvious at first glance, and if disassembled incorrectly, it can cause mounts to break or damage electronic components.

Follow this instruction:

1. Remove the top cover. To do this, press the unlock button (at the back) and pull the lid up. Don't put too much effort -- if the lid doesn't lend itself, check if the remaining water in the tank is blocking it.
2. Remove the water tank. It's attached to the guides -- gently pull it on you, holding the base of the device with your other hand.
3. Take out the antibacterial filter. It's at the bottom of the tank, and it's fixed by the plastic holder. Don't wash the filter under running water, it's disrupting the structure!
4. Disconnect the spray module (if you need deep cleaning) and press the latches on the sides and pull the module upwards, and be careful, there are fragile membranes inside.

📌 Important nuance: The Mi Smart Antibacterial Humidifier has a hidden drainage hole at the bottom of the base, which must be cleaned with a toothpick at least 1 time per month, otherwise the water will stagnate, creating an ideal environment for bacteria.

If you notice that after disassembly, there is black or green plaque at the bottom of the tank, it is mold, in which case you will need to disinfect with hydrogen peroxide (see section 4).

3. Cleaning of the reservoir and elimination of scale: proven methods

The main problem in the operation of humidifiers is the formation of scale due to hard water. In Xiaomi Mi Smart Antibacterial Humidifier, scale accumulates not only on the walls of the tank, but also on the ultrasonic membrane, which reduces the performance of the device.

Effective methods of cleaning:

⚠️ Attention: If the scale is not removed by conventional methods, do not scrape it with a knife or a metal sponge! This leads to microcracks in which bacteria multiply.

After cleaning the tank, be sure to dry it in air for 1-2 hours. The humid environment promotes rapid re-formation of mold.

💡

To reduce scale, use distilled water or add special cartridge softeners (such as Xiaomi Water Softener Cartridge) to the tap water.

4. Cleaning the antibacterial filter: can I wash and how to properly

The antibacterial filter is a key feature of the Mi Smart Antibacterial Humidifier, which prevents bacteria from multiplying in water but requires special care. Many users make the critical mistake of washing the filter under running water or boiling it, destroying the antibacterial coating and negating all the benefits of the device.

How to properly care for the filter:

• 🚫 Don't wash under the tap, just wash the filter in warm boiled water without detergents.
• 🔄 Change the filter every 2-3 months (or more often if the water is very hard). WFA01.
• ☀️ Dry the filter in the shade. Direct sunlight destroys the antibacterial layer.
• ⏱️ Do not use the filter for longer than 6 months – even if it looks clean, its effectiveness drops by 70 months%.

⚠️ Warning: If the filter starts to crumble or odor, it needs to be replaced immediately, which is a sign that the antibacterial coating has collapsed and the filter has become a source of contamination.

The Mi Home app has a Filter Life feature that reminds you to replace. Don't ignore these notifications! Using an expired filter can lead to:

• 🦠 Reproduction of Legionella (dangerous bacteria).
• 💨 Deterioration of spray quality (the appearance of white plaque on furniture).
• 🔊 Increased noise during operation of the device.

5. Cleaning the ultrasonic membrane and sprayer: why it is critical

The ultrasonic membrane is the heart of Xiaomi Mi Smart Antibacterial Humidifier, which vibrates at a high frequency, breaking water into tiny particles. If the membrane gets contaminated, the device's performance drops by 40 to 50 percent, and not only steam, but also scale particles enter the air.

How to clean a membrane:

1. Disconnect the spray module (as described in Section 2).
2. Wet the cotton swab in a solution of citric acid (1 tsp per 100 ml of water) and gently wipe the membrane. Don't press hard!
3. To remove plaque from the sprayer holes, use a toothpick soaked in the same solution.
4. Wash the module under a weak stream of warm water (not hot!).

⚠️ Warning: If the humidifier starts to work louder or makes whistling sounds after cleaning, this is a sign of damage to the membrane. DMF01 for this model).

📌 Useful tip: To keep the membrane lasting longer, don't turn the humidifier on at maximum power all the time. Optimal mode is 50-70% of maximum performance. This reduces the load on the membrane and reduces the formation of scale.

6. Disinfection of the humidifier: when and how to carry out

Even with regular cleaning, bacteria and mold can multiply in the humidifier, especially if the device is used in rooms with high humidity (for example, in the bathroom). Disinfection is recommended 1 time per month, as well as in the following cases:

• 🤢 The humidifier began to emit a musty or rotten smell.
• 💧 Water in the tank becomes cloudy or there is a green / black coating.
• 😷 Households have allergic reactions (sneezing, coughing) after turning on the device.

Effective methods of disinfection:

After disinfection, be sure to rinse all the parts at least 3 times and dry the humidifier for 2-3 hours. If the smell of the disinfectant remains, repeat rinsing.

⚠️ Warning: Do not use alcohol-containing products (such as vodka or medical alcohol) to disinfect plastic parts and leave toxic fumes that will be sprayed into the air.

7.Typical cleaning errors and how to avoid them

Many Xiaomi Mi Smart Antibacterial Humidifier users make mistakes that shorten the life of the device or impair the quality of its operation.

Another common problem is that the humidifier is not properly assembled after cleaning, and if the humidifier doesn't turn on or leaks after assembly, check:

• 🔌 Is the spray module installed correctly (should be clicked when fixing).
• 💧 Is the drainage plug at the bottom of the base closed.
• 🔄 Is the antibacterial filter inserted correctly (it should lie flat, without distortions).
