How to properly wash the drum of a Xiaomi moisturizer: full instructions

Modern ultrasonic humidifiers from Xiaomi, such as the Mi Smart series or Deerma, have become an integral part of the microclimate in many apartments. However, despite the presence of antibacterial coatings and sterilization systems, regular hygiene of the device remains the responsibility of the user. Ignoring this rule leads to the accumulation of biofilm, the appearance of unpleasant smell and, as a result, the spread of bacteria in the air you breathe.

Many owners mistakenly believe that it is enough to add fresh water, but salt plaque and mucus require mechanical removal.In this guide, we will discuss how to wash the drum of a Xiaomi humidifier to extend the life of the device and ensure a healthy atmosphere in the house.

Before you start the procedure, you need to understand that different models can have design features, you need to remove the bottom somewhere, and you need to remove the internal container somewhere. Safety is the first and foremost step: always disconnect the device from the network before you start any manipulation of water and electrical components.

⚠️ Warning: Never immerse the base of the electronics appliance in water completely. Only removable plastic elements and tanks can be washed.

Preparation for cleaning and necessary means

To clean effectively, you'll need a minimal set of items that you're sure to find in the kitchen or the bathroom, and the main enemy of the humidifier is hard water that leaves behind limestone plaque, which requires acid to deal with, and safe antiseptics to disinfect.

Do not use aggressive household chemicals, chlorine-containing products or abrasive powders. They can damage the ultrasonic membrane or leave a toxic layer on the walls, which will then be sprayed into the air. The optimal choice is citric acid or table cider vinegar, which perfectly dissolves calcium salts.

• 🍋 Citric acid (packet) 20-50 (d) or 9% acetic acid.
• 🧽 Soft sponge or brush with gentle pile (old toothbrush is perfect).
• 💧 Distilled or filtered water for final rinse.
• 🧤 Rubber gloves to protect the skin of the hands from acid.

Prepare a container that will hold a humidifier tank if you plan to soak it whole, which will speed up the process of softening the scale, and also make sure you have access to a sink to drain dirty water.

Disassembly of the device: remove the tank and base

The dismantling process depends on the specific model Xiaomi Mi Humidifier. In classic models such as MJJSQ or FJS, the water tank is removable and mounted on top of the base with an ultrasonic emitter. You need to carefully remove the top, flip it over and unscrew the bay cover.

In more modern models, such as the Smartmi Evaporative series or the Deerma DEM-F600, the design may be different. It is important not to put too much effort into this. If the tank is not removed, check for latches or stoppers. Mechanical impact can break plastic mounts.

⚠️ Note: In some models, the electronic base and the tank form a single unit, in which case only the inner bowl can be washed "under the tap", preventing water from entering the technical holes.

Once you remove the tank, you'll see the bottom of the main platform, and you'll see a circular metal plate or ceramic plate -- that's the ultrasonic membrane -- that vibrates at a high frequency, breaking water down into tiny particles, and that part should be treated with special care.

Scaling and lime plaque removal

Scale is the hardened salts of calcium and magnesium that are found in tap water. Over time, the scale layer becomes thick, which reduces the efficiency of evaporation and can lead to overheating of the device. To remove plaque, we use a chemical reaction of acid and salts.

Prepare the solution: dilute 2-3 tablespoons of citric acid or 50 ml of vinegar in a liter of warm water. Pour this solution into the humidifier tank, close the lid and shake well so that the liquid washes all the walls. Leave the device in this form for 30-60 minutes.

If the plaque is very strong and looks like a thick crust, the soaking time can be extended to 2-3 hours. The acid will gently dissolve the deposits without damaging the plastic. After soaking, pour the solution and walk with a soft brush on the inner walls.

Pay special attention to the area around the ultrasonic membrane on the base. If there is white plaque, moisten the cloth in an acid solution and gently wipe the surface. Metal sponges and knives are forbidden to use, they will scratch the membrane coating, and it will fail.

Disinfection and control of bacteria

Once the visible dirt and scale is removed, the disinfection stage begins. Even if the device looks clean, microorganisms can multiply inside, causing the so-called "legionella" or just a bad smell of mustyness. It is important for Xiaomi humidifiers to use safe means.

One effective and safe method is to use hydrogen peroxide, put 3% peroxide solution in a clean tank and leave it for 15-20 minutes, and it will kill most bacteria and molds, and you can also use special humidifier disinfectants if they are compatible with your model.

After the disinfection procedure, you need to rinse all the parts very carefully with running water, so the residue of cleaning products should not remain inside, otherwise they will enter the air the next time they turn on.

Cleaning of ultrasonic membranes and sensors

The central element of any humidifier is the membrane, and it often forms a microscopic coating on its surface, which reduces the amplitude of the vibrations, which visually manifests as a decrease in the amount of vapor released.

To clean the membrane, use a cotton swab dipped in a solution of citric acid. Walk around the surface in a light circular motion. You'll notice the plaque starting to move away. The main thing is not to push hard. The ceramic layer is quite strong, but if you hit it hard, it can crack.

💡

If the steam gets worse after cleaning, you may not have completely washed the acid or damaged the membrane, and try to run the device with clean water for 10 minutes in a ventilated room.

Also check for a water level sensor (usually a tongue on the side or floats) that should move freely. If it sticks because of dirt, the device may not turn on or work with errors.

Drying and assembly of the device

The final step is drying properly. Don't rush to pack it up and put it on the shelf. The humid environment inside the closed tank is the perfect place to quickly develop a new colony of bacteria.

Put all the parts in a clean towel in a well-ventilated place. Leave them until completely dry. If possible, put them in the sun — UV light is a great natural disinfectant. It takes 2 to 4 hours to dry completely, depending on the humidity in the room.

Once all the elements have dried, assemble the humidifier in reverse order, make sure all the sealing gums are in place and the lid is tightly swirled, and the device is now ready for use.

💡

Regular drying of the tank after use prevents 90% of problems with unpleasant odor and mucus inside the tank.

Prevention and frequency of service

To avoid wasting time on a complex cleaning every two weeks, follow simple prevention rules: the frequency of washing depends on the hardness of the water you use and the intensity of operation.

If you use tap water, do a full acid cleaning every 1-2 weeks; if you pour distilled or filtered reverse osmosis water, just wash the tank once a month; it is recommended to change the water daily if it has stood for more than 24 hours.

• 💧 Use filtered water to minimize scale.
• 🔄 Change the water in the tank daily, do not leave it for tomorrow".
• 🌬️ Ventilate the tank when the device is not working.
• 🚫 Do not add essential oils to the water if the instructions for the Xiaomi model do not have a special compartment for flavoring.

Compliance with these guidelines will allow your humidifier to last long and efficiently, and a clean appliance is the key to the health of your respiratory system.
