How to carefully disassemble the air humidifier Xiaomi: models Smartmi, Mi Air and others

Xiaomi’s humidifiers (including Smartmi and Mi Air sub-brands) have long been a popular solution for maintaining a comfortable microclimate. However, even the most reliable appliances require periodic maintenance: cleaning scale, replacing filters or troubleshooting. Disassembling the device is the first step in the process, but many users are afraid to damage fragile parts or lose the warranty.

In this article, we will discuss in detail how to properly dismantle the case of different models of Xiaomi humidifiers, what tools you will need, and what to look for to avoid breaking clips or electronics. Separately, we will focus on the typical errors that lead to breakdowns, and give recommendations for safe assembly after maintenance. If your humidifier stops turning on, makes noise or does not spray water well, here you will find the answers to diagnose the problem yourself.

What Xiaomi moisturizers can be disassembled independently

Not all Xiaomi humidifiers are designed for custom disassembly. The manufacturer provides maintenance for some models where the body is glued or fixed with non-shatterable latches. However, most popular devices can be neatly dismantled at home.

Here is a list of models for which this instruction is suitable:

• 🔹 Xiaomi Smartmi Air Humidifier 2 (JSQ06YM) — ultrasonic
• 🔹 Xiaomi Smartmi Air Humidifier 2S (JSQ06YM-2S) — Updated version with improved management
• 🔹 Xiaomi Mi Air Humidifier Pro (JSQ1) — model with a large tank (4.5 liters) and hygrosate
• 🔹 Xiaomi Smartmi Evaporative Humidifier 2 (JSQ04YM) — evaporative type with antibacterial filter
• 🔹 Xiaomi Smartmi Air Humidifier Lite – compact version for small rooms

Xiaomi Mi Air Humidifier 1 (first generation) and some specialized devices (e.g. Xiaomi Mi Smart Antibacterial Humidifier) have a non-shattered bottom design. Their disassembly requires a complete body replacement and is not recommended without experience.

Preparation for disassembly: tools and security measures

Before you start dismantling, prepare the workplace and the necessary tools, disassemble the humidifier should be on a flat, stable surface covered with a soft cloth (for example, a towel) so as not to scratch the case and lose small parts.

You'll need:

• 🔧 Plastic spatula (mediator or specialized tool for disassembling gadgets)
• 🔧 Cross screwdriver (usually) PH0 or PH1)
• 🔧 Tweezers – to extract small details
• 🔧 Soft brush – for cleaning dust inside the case
• 🔧 Isopropyl alcohol (70%+) — contact-degreasing
• 🔧 Container for screws - so as not to confuse fasteners

Important: If your humidifier is still warranty, disassembly will cancel it. Check the validity of the warranty card before starting work. Also make sure that the device is disconnected from the network and the tank is completely empty - the residue of water can damage the electronics if hit on the board.

⚠️ Warning: Do not use metal screwdrivers or knives to disassemble! Plastic clips of the case easily break under excessive pressure. If the latch does not lend itself, check if all screws are twisted.

Step-by-step: how to disassemble the Xiaomi Smartmi Air Humidifier 2 humidifier

Consider the process using the most popular model, the Xiaomi Smartmi Air Humidifier 2 (JSQ06YM), the design of the other devices in the series is similar, except for the location of the screws and the number of latches.

Step 1 Removing the top cover

Turn the humidifier upside down. You'll see 4 rubber legs at the bottom of the body, there are screws underneath, gently put your feet in a plastic spatula and remove them. There's a cross-shaped screw underneath each leg, and you'll unscrew all four.

Step 2: Dismantling the bottom panel

Once the screws are removed, the bottom panel is held onto the plastic latches. Start gently snapping it off with the shoulder blade as you move around the perimeter. Start at the corner where the power connector is located, there's usually less resistance. Be careful: there may be wires inside that connect the control panel to the main board.

Step 3: Removal of the electronic unit

Once you remove the bottom cover, you'll see the control board and the fan. Disconnect all the plumes (they're usually fixed with clips -- lift them up with tweezers. The screws that attach the board can be hidden under stickers -- check for them. Take the board carefully and put it aside.

Step 4: Disassembly of the upper part (tank and sprayer)

The top of the humidifier (where the water tank is) is attached to the base on 2-3 screws and latches. Unscrew the screws and carefully separate the parts. Inside, you'll find an ultrasonic membrane module, which is the most sensitive part of the device. Don't touch the membrane with your hands!

Cleaning and replacing filters: what you can do yourself

Once you've disassembled the humidifier, you can do a deep cleaning or replace the consumables, and this is what's available for self-service:

To replace the filters, use original parts from Xiaomi or compatible analogues. For example, for Smartmi Air Humidifier 2, the Xiaomi JSQ-S04 filter is suitable. Poor-quality substitutes can lead to overheating of the device or poor spraying.

⚠️ Warning: If a membrane has white stains or has deformed, it's a sign of failure, and it can't be cleaned, it can only be replaced.

💡

Before assembly, dry all parts with a hair dryer (cold mode) - this will remove moisture residue and prevent short circuiting at the first turn on.

Typical malfunctions and how to fix them

If Xiaomi’s humidifier stopped working correctly, the causes could be mechanical or electronic, and here are the most common problems and ways to solve them:

• 💧 It doesn't spray water, but the fan works: Check the water level in the tank (the sensor may get contaminated). Clean the ultrasonic membrane from scale. Make sure the filter isn't clogged (wash or replace it).
• 🔌 Not turning on, the indicators are not burning: Check the power supply (try another socket); inspect the board for burnt-out elements (blackened resistors, swollen capacitors); make sure all plumes are tightly connected.
• 🔊 Heavy noise or vibration: Grease the fan bearing with silicone lubrication. Check the membrane's attachment - it may have shifted. Remove foreign objects from the tank (such as scales of scales).
• 📶 Reset your device (press the power button for 10 seconds) Reconnect the device to Mi Home. Update your firmware through the official app.

If the humidifier doesn't work after cleaning and assembly, the problem may be in the electronic unit, which requires a multimeter diagnostic or help from a service center, such as a frequent failure of the transistor on the board that powers the membrane.

Assembly of the humidifier after disassembly: step-by-step algorithm

Incorrect assembly can lead to leaks, short circuits or breakage of plastic parts.

1. Place the membrane in place, making sure it's flat, and the contacts should fit tightly into the board.
2. Connect all the plumes to the control board, make sure the clips are snapped to the end.
3. Fill the board with screws. Don't drag them over, it could damage the tracks.
4. Collect the body starting from the bottom panel. Make sure all latches are in place (you will hear a characteristic click).
5. Set the rubber legs and twist the screws, and make sure that the device is stable.
6. Pour the water and check the leaks. Wait 5-10 minutes -- if there's no leaks, you can plug it in.

After assembly, perform a test run:

1. Put the humidifier in the socket.
2. Activate maximum spraying mode.
3. Check that the steam comes out evenly, without jerking.
4. Make sure the fan is working without any extraneous sounds.

⚠️ Warning: If after assembly the humidifier starts to smoke or the smell of burning, immediately disconnect it from the network! This is a sign of short circuit. Disassemble the device and check that the plumes are connected correctly.

💡

The most common assembly error is a skewed membrane, and if it's unevenly installed, the humidifier will malfunction or not turn on at all.
