How to disassemble the air washer Xiaomi: detailed instructions with photos and tips

Xiaomi air washes (including Smartmi models) have become an integral part of smart homes thanks to efficient air cleaning and humidification. However, over time, any device requires maintenance, whether it is replacing filters, cleaning the fan or troubleshooting. Disassembling air washing is a delicate process, and without knowing the nuances, you can damage plastic latches, seals or even electronic components.

In this article, we will discuss in detail how to disassemble popular models of air washers Xiaomi (for example, Smartmi Air Purifier). P1, Mi Air Purifier Pro, Smartmi Evaporative Air Humidifier 2, what tools you need and what to look for to avoid losing your warranty, and what mistakes users most often make when disassembling the first one and how to avoid them.

What models of air washer Xiaomi can be disassembled independently

Not all Xiaomi air washes are designed for user disassembly. The manufacturer plans to provide service only for some models, and in other cases recommends contacting service centers. Below is a table with popular devices and their collapsible status:

If your model doesn’t make the list, check the documentation or search the forums (e.g., for example, 4PDA Ultrasonic humidifiers (like Mi Air Humidifier 2) are usually disassembled only to replace the filter or clean the membrane - trying to get to the control board can lead to breakage.

⚠️ Warranty-sealed models (such as Smartmi Fresh Air System) are not warranty-free when they are opened. If the device is warranty-sure, check with the service center first if your problem is covered by free repairs.

Preparation for disassembly: tools and security measures

Before you start dismantling, prepare the workspace and tools.

• 🔧 Plastic blades (or mediators) - to disconnect latches without scratches.
• 🔩 Cross screwdriver (usually) PH2) — hull-holding screw.
• 🧴 Silicone lubricant – for processing seals after cleaning.
• 📸 Smartphone – to photograph the process (useful when assembling).
• 🧼 Soft fabric and isopropyl alcohol - for cleaning contacts and plastic parts.

Security measures:

• ⚡ Disconnect the device from the network at least 30 minutes before disassembly (capacitors can retain charge).
• 💧 If the air wash combines cleaning and humidification - drain the water and dry the pallet.
• 👓 Work with gloves: There may be sharp plastic elements or residues of detergents inside.

If you're disassembling the device for the first time, check out the video instructions on YouTube (Xiaomi Today or Smartmi Russia channels often post detailed guides). Pay attention to the locations of hidden latches - their damage can lead to backlash of the case after assembly.

The Xiaomi Smartmi Air Purifier is a step-by-step air washing P1

Let’s look at the process using the example of one of the most popular models – Smartmi Air Purifier. P1. This air washer has a removable water tank and a filter unit, but for deep cleaning or repairs you will need to disassemble the case.

Step 1: Remove the top cover

1. Turn the device upside down (on a soft surface so as not to scratch).

2. On the bottom of the case, find 4 rubber plugs, and there are screws underneath. Carefully put them in the shoulder blade.

3. Unscrew the screws. PH2 Then put them aside (they may differ in length!).

Step 2: Separation of the hull

1. Insert a plastic shoulder blade into the gap between the top and bottom of the case (start at the corner where there are no buttons).

2. Carefully drive the blade along the perimeter, alternately snapping the clamps. Do not apply force - if the body does not respond, check if all screws are twisted.

3. After disconnecting, remove the upper cover and put it aside.

Step 3: Access to internal components

Now you'll see:

• 🔋 Power supply (left).
• 🌀 Fan (centre).
• 💧 Water pallet (right, if the model is moistened).
• 📱 Control board (usually under a protective screen).

To clean the fan, it is enough to remove its fastening (usually) 2-3 If you need to get to the board, carefully disconnect the plumes (remember their location!).

💡

If the latches of the case break during disassembly, they can be temporarily replaced with small pieces of plastic glued with superglue, but this does not guarantee leakproofness - it is better to order the original clips from the manufacturer.

Cleaning and maintenance of internal components

After the disassembly, it's time to get the device in order.

1. Cleaning the fan

The fan is the most polluted element, and the dust and mineral deposits from the water reduce its efficiency.

• 🧽 Wash the blades with warm water with a mild detergent (e.g. Fairy).
• 🧼 To remove plaque, use acetic solution (1: 1 with water) or citric acid.
• 🔍 Check the fan bearing - if it creaks, apply silicone lubricant.

Water pallet maintenance (for moisture models)

And then you get a biofilm and a lime plaque in the pallet over time.

1. Soak the pallet in a solution of vinegar on 1-2 hour.
2. Clean with a brush (not metal!).
3. Wash it under running water and dry it.

3. Electronics check

If the air wash does not turn on or is not working stable, check:

• 🔌 Power supply contacts - oxidation can cause failures.
• 📶 The sleeves – they must be tightly connected to the board.
• 🔥 If there is a fire, then it may have been destroyed.

Common Mistakes in Disassembly and How to Avoid Them

Even experienced users sometimes make mistakes that lead to breakdowns.

1. Too much pressure on the latches → hull-crevices. ✅ Solution: Use two shoulder blades at the same time, distributing the load.
2. Loss of screws or confusion in their location → hull backpack. ✅ Solution: Fold the screws in signed containers (for example, "top - 4 pieces, long ones").
3. Moisture on the board → short-circuit. ✅ Solution: Dry all details for at least 24 hours before assembly.
4. Damage to plumes → idle. ✅ Solution: Disconnect the plumes by putting on a black tongue-fixer, not for wires.

⚠️ Note: If after assembly of the air washing gives an error E1 or E2, This could mean improper installation of the water tank or sticking of the water level sensor.

When the disassembly will not help: signs of serious breakdowns

Not all air washing problems are solved by cleaning or replacing filters. If you notice the following symptoms, you may need professional repair or replacement of parts:

If you are not sure of your abilities, it is better to contact a service center, for example, changing the control board in the Smartmi Air Purifier. P1 It is cheaper than buying a new device, but requires special equipment.
