How to wash the air washer Xiaomi: full instructions with photos and tips

Xiaomi air wash is not just a humidifier, but a complex device with a filtration system and ultrasonic spraying, and over time, mineral deposits, molds and bacteria accumulate on its internal elements, which not only reduce efficiency, but can also harm health. However, many users make critical cleaning mistakes: using aggressive detergents, damaging the membrane or improperly drying components. This article will help you understand how to wash Xiaomi air wash without the risk of breakage, taking into account the features of different models. 2/3, Smartmi Air Humidifier and others.).

We will look at the process of disassembling, flushing each element (including the ultrasonic module and HEPA filter), and give recommendations on the choice of safe detergents and the frequency of maintenance. We will focus on typical problems, for example, why the device starts to make noise after cleaning or does not spray water well. If you have never cleaned your sink or did it “by eye”, this instruction will be your salvation.

Why Xiaomi Air Washing Should Be Cleaned Regularly

The inner surfaces of the air wash are the perfect environment for microbial reproduction. Humidity, warm air and organic particles from the water create conditions comparable to an incubator for bacteria and fungi. Studies show that after 2-3 weeks of use without cleaning, a biofilm can form in the tank, a mucous plaque that not only emits an unpleasant odor, but also sprays into the air along with the vapor.

In addition to hygienic risks, pollution affects the technical characteristics of:

• 🔋 Decreased performance: Scaling on the ultrasonic membrane reduces the amplitude of the oscillations, which makes water spraying less intense.
• 💧 Increased water consumption: clogged filters make the device work longer to achieve a predetermined humidity.
• 🔊 Increased noise: deposits on the fan or bearings lead to vibrations and foreign sounds.
• ⚡ Risk of failure: lime plaque on sensor contacts can cause malfunctions in electronics.

The manufacturer Xiaomi recommends a full cleaning at least 1 time every 2 weeks with daily use. However, if you poured tap water into the device (not distilled), the interval should be reduced to 10 days. In regions with hard water, scale is formed faster - its crystals can damage the membrane after a week of active use.

What you need to clean: tools and detergents

Before you start dismantling, prepare everything you need, and using the wrong tools is one of the main causes of breakage after cleaning, for example, vinegar or citric acid in high concentrations can eat rubber seals, and hard brushes can scratch the ultrasonic membrane.

Here is a safe cleaning kit:

• 🧽 Soft sponge (for example, to wash dishes) or microfibre wipe.
• 🧴 Liquid soap or baby bottle product (without fragrances and abrasives).
• 🍋 Citric acid solution (1 tbsp. l. per 1 liter of water) - only for the removal of scale, not for regular cleaning!
• 🧻 Paper towels or cotton fabric for drying.
• ⚙️ Plastic spatula or old bank card - for careful removal of plaque in hard-to-reach places.
• 💧 Distilled water for rinsing (the tap water can leave a new layer of scale).

What NOT to use:

• 🚫 Abrasive powders (Pemolux, soda) - scratch the surface.
• 🚫 Chlorine-containing products (White) – destroy plastic and rubber.
• 🚫 Metal brushes or knives – damage the membrane and filters.
• 🚫 Concentrated vinegar – can deform seals.

💡

If you have an antibacterial model (such as Smartmi Air Humidifier 2), avoid alcohol-containing products – they destroy the protective layer.

Step-by-step: how to disassemble the air wash Xiaomi

Disassembly is the most critical step. Mistakes can damage latches or water into the electronic unit. We will look at the process in the popular Mi Air Humidifier 3 model, but the steps are relevant for other versions as well (we will specify the differences separately).

Disassembly order:

1. Disconnect the device from the network and drain the remaining water through the drainage hole (usually located at the bottom of the tank).
2. Remove the top cover: press the latches on the sides (on some models you first need to turn the lid counterclockwise).
3. Remove the water tank - pull it upwards while holding the body with the other hand.
4. Remove the ultrasonic module: it is mounted on latches or screws (in Smartmi Air Humidifier, screws can be hidden under stickers).
5. Remove the fan and filters (if your model has them). In Mi Air Humidifier 2, the filter is attached to magnets.

In models with a hygrostat (humidity sensor), be careful: do not pull the wires or urinate the electronic unit. If the sensor is contaminated, wipe it with a dry cotton swab dipped in alcohol (no more than 70% of the concentration).

Features for different models:

How to Clean an Ultrasonic Module and Membrane

The ultrasonic module is the heart of the air wash, and it converts water into fine vapor, and over time, it forms a mineral plaque that blocks the vibrations of the membrane, and you need to clean this element with special care, because damage to the membrane will cause the device to become completely inoperable.

Cleaning instructions:

1. Wash the module under running water, removing visible contaminants with your fingers (not your nails!).
2. Prepare a solution: 1 tbsp. l. citric acid per 1 liter of warm water (temperature not higher than 40)°C).
3. Immerse the module in the solution for 20 to 30 minutes. Don't use vinegar, it can deform the membrane!
4. With a soft sponge, remove the softened plaque. Use a cotton swab for hard-to-reach areas.
5. Rinse thoroughly with distilled water and dry in air (not with a hairdryer!).

If there's a dark spot on the membrane, it could be mold.

• 🧪 Prepare the solution: 1 tsp. hydrogen peroxide (3%) per 1 cup of water.
• 🕒 Soak the module for 15 minutes.
• 🧼 Wash and dry.

⚠️ Warning: Never rub a membrane with hard materials! It consists of a thin piezoelectric layer that is easily damaged. If the washer stops spraying after cleaning, the membrane is likely damaged, you will need to replace the module.

Cleaning the tank, filters and housing

The water tank is the second most important element that requires regular maintenance, and it accumulates not only mineral deposits, but also biological contaminants (algae, bacteria), and the filters (if you have them in your model) also need cleaning or replacement.

How to clean the tank:

1. Pour a warm soap solution (liquid soap or baby bottle remedy) into it.
2. Add a few drops of vinegar (only if there is no antibacterial coating!).
3. Use a soft brush to clean the walls, bottle brushes are good for bottle bottle bottle bottles.
4. Thoroughly rinse with distilled water 2-3 times.

Filter care:

• 🔄 The HEPA filter (if any) can be washed under running water 1 time per month. After 3-6 months of use, it should be replaced.
• ♻️ Coal filter (in Pro models) is not washed - only replacement every 3 months.
• 💧 Antibacterial filters (for example, in Smartmi) rinse with water without detergents.

Clean the sink with a wet microfiber wipe dipped in soapy solution. Avoid vents and electronics. Use a minimum power vacuum cleaner or a soft pile brush to clean the fan grille.

💡

After cleaning, all parts must be completely dry before assembly. Residual moisture in the electronic unit or on the contacts can cause a short circuit!

Assembly and first start after cleaning

Improper assembly is a common cause of malfunctions after cleaning. For example, if you do not fasten the ultrasonic module, the sink will work louder than usual, and if you install the filter incorrectly, the humidification efficiency will drop by 2 times.

Assembly order:

1. Check the dryness of all the parts. Pay special attention to the ultrasonic module and sealing gums.
2. Install filters (if any) In the magnetically mounted models (Mi Air Humidifier 2), make sure the filter is "stick" on all sides.
3. Hold the ultrasonic module tightly, without backlashes, and in some models, you have to click it.
4. Set the tank and lock the top cover, make sure all latches are snapped.
5. Pour distilled water (not above the maximum mark) and turn the device on the network.

At the first start after cleaning:

• 🔍 Check if there are any leaks (especially if you have removed seals).
• 🔊 Listen to the sound: extraneous noise may indicate improper installation of a fan or module.
• ☁️ Make sure the vapor is sprayed evenly.If the flow is weak, it's possible the membrane is damaged or poorly cleaned.

⚠️ Warning: If the sink does not turn on after assembly, check: Is the tank installed correctly (some models have protection against improper assembly) is dry contacts at the bottom of the device (when water enters, protection may work). If the power cord is tightly connected (sometimes after cleaning, the connector oxidizes). If the problem persists, the device needs to be dried 24 hours without connecting to the network.

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes that lead to breakages or reduce the efficiency of the wash, and here are the most common mistakes and how to prevent them:

1. Use of tap water

Hard water leaves a scaling that clogs the membrane and shortens the life of the device. Solution: use distilled or filtered water (boiled water can be used, but it is less efficient), and add special water softening cartridges (sold for humidifiers) to the tank as a last resort.

2. Cleaning without disconnecting from the network

If you get water on the electronics, you can short circuit. Solution: always take the plug out of the plug and drain the water before disassembling. If you do get water on the board, don't turn it on for 24 hours, let it dry completely.

3 Drying with a hair dryer or on a battery

The high temperature deforms plastic and rubber seals. Solution: Dry parts at room temperature on a towel, avoiding direct sunlight.

4. Ignoring filters

Clogged filters reduce productivity by 40-50% Solution: flush the HEPA filter once a month, and replace the coal filter every 3 months (even if it looks clean on the outside).

5. Aggressive detergents

Chlorine, acetone or concentrated acids destroy materials, solution: use only neutral detergents (pH 5-8) or specialized humidifier formulations.

💡

If you start to make gurgling noises after cleaning the sink, it means that there is air in the tank. Turn off the device, shake it and turn it on again. If the sound is still there, check the sealing rubber bands.
