How to properly wash the air humidifier Xiaomi

Xiaomi’s ultrasonic air humidifiers and sub-brands like Smartmi or Deerma have proven to be reliable and quiet, but like any water-contact device, they require regular maintenance, and ignoring hygiene rules can lead not only to breakdowns in the equipment, but also to the spread of bacteria in the air you breathe.

In this article, we will discuss in detail how to flush the xiaomi air humidifier to extend its life and ensure a healthy indoor climate. You will learn about the nuances of cleaning the membrane, water tank and humidity sensors, and what tools are really effective against scale.

Many smart homeowners face the problem of white plaque on furniture or the unpleasant smell of a “swamp” when the appliance is running, most often due to late cleaning or using poor-quality water. Proper care takes only 10-15 minutes, but the result is worth it.

Frequency and need for service

The manufacturer recommends that you clean the device completely at least once a week if you use it daily, and even filtered water contains mineral salts that settle on the inside, and over time, this layer of scale begins to interfere with the ultrasonic membrane, reducing the performance of the device.

If you notice that the fog has become less intense, or the device makes gurgling sounds, this is a good signal for an unscheduled cleaning. It is also important to consider the water quality in your area. In areas with hard water, you will have to wash the air humidifier Xiaomi more often, perhaps every 3-4 days.

Special attention should be paid to periods of downtime. If you do not plan to use a humidifier for more than three days, be sure to drain the remaining water and dry all the containers. Stagnant water is the ideal environment for the reproduction of microorganisms that will fly around the room the next time you turn on.

Tools and tools needed

Before you start the procedure, you have to prepare the right inventory, and the use of aggressive chemicals, such as chlorine-bearing bleach or abrasive powders, is strictly forbidden, and they can damage the plastic and leave toxic traces that will evaporate with the vapor.

For safe and efficient cleaning, you will need:

• 🍋 Citric acid or table cider vinegar (9%) – to remove mineral deposits.
• 💧 Distilled or filtered water – for rinsing and further use.
• 🧽 Soft sponge or microfiber – for rubbing surfaces without scratches.
• 🪥 Old toothbrush – for cleaning hard-to-reach places and around the membrane.
• 🧤 Rubber gloves – to protect the skin of the hands from acidic environment.

The main active ingredient in the fight against scale is acid, which reacts with the salts of calcium and magnesium, softening them and allowing them to be easily washed away with water. Citric acid is preferable to vinegar, because it does not leave a sharp smell, which is difficult to weather out of the plastic tank.

💡

Use only dietary citric acid. Technical varieties may contain impurities that are dangerous to inhalation.

Step-by-step: disassembly and washing of the tank

The process of flushing the Xiaomi air humidifier begins with the device being completely disassembled. Make sure the appliance is off the grid. Remove the plug from the socket and let the device cool if it was running in hot steam mode (although most Xiaomi models are cold).

Remove the top cover and the water tank. There may be some liquid in the tank that needs to be drained. Turn the tank over to remove as much water as possible, and start treating the interior walls. This is where slippery plaque most often forms.

Pour a warm solution of citric acid (about 2-3 teaspoons per liter of water) into the tank. Leave the container for 20-30 minutes. During this time, the acid will dissolve most of the sediments. After soaking, thoroughly rub the walls with a sponge. Pay special attention to the corners and joints where dirt accumulates most quickly.

After mechanical cleaning, rinse the tank several times with clean water until any traces of the cleaning product disappear, it is important that there are no acid crystals left inside, otherwise they can get into the ultrasound chamber when working.

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

Cleaning of the ultrasonic membrane and base

The most delicate part of the device is the ultrasonic membrane at the base, which is a round metal disc that vibrates at a high frequency, breaking water into a mist, and it forms the fastest solid layer of scale that blocks the vibrations.

You can't use hard brushes, knives or metal scrapers to clean the membrane. Even a small scratch can break the integrity of the coating and put the element out of order. Use a soft toothbrush soaked in a citric acid solution.

Carefully brush the surface of the membrane, removing the white plaque, the movement should be easy, without strong pressure, if the scale layer is very thick, you can put on the membrane a cotton disc, moistened in a concentrated solution of acid, and leave for 10-15 minutes.

After cleaning the membrane, be sure to wipe the base with a wet and then dry cloth. Make sure there is no fluid left in the water compartment before assembly.

Disinfection and removal of odors

Sometimes even after the scale is removed, the device still has an unpleasant odor, indicating that there is a bacterial or fungal film that the acid does not always remove efficiently, and in such cases additional disinfection is required.

For disinfection, you can use special tablets for humidifiers, if recommended by the manufacturer, or a weak solution of hydrogen peroxide. Pour the solution into the tank, turn the device on for 10-15 minutes (without a lid, in a well-ventilated room) so that the fog treats the internal paths.

After the "vaporization" procedure with a disinfectant, be sure to thoroughly rinse all the parts with clean water several times. Residues of peroxide or chemicals should not enter the air. To eliminate odors, soaking parts in a soda solution also helps effectively.

⚠️ Warning: Do not mix vinegar, hydrogen peroxide and chlorine-containing products. This can lead to a chemical reaction with the release of dangerous gases.

Drying and assembly of the device

The final step in how to flush the humidifier Xiaomi is to dry properly. Don't rush to collect wet parts. The plastic and internal ducts must be completely dry to prevent mold from re-evolving.

Leave disassembled components at room temperature for a few hours or overnight.Do not use a hair dryer to speed up the process, as hot air can warp thin plastic or damage adhesive joints.

Make sure the water level sensor (float) is free to walk in its well and not stuck. Collect the device in reverse order, pour fresh water and check the work. If done correctly, the fog should be abundant and have no foreign smells.

💡

Complete drying of all components before storage or assembly is the main guarantee of the absence of mold and unpleasant odors in the future.

Prevention and maintenance advice

To be less likely to ask yourself how to flush a Xiaomi humidifier, you should stick to simple rules of operation, first of all, using quality water. Pouring water directly from the tap is the main reason for rapid scale formation.

The ideal option is distilled water or reverse osmosis filter water, which has virtually no salts, so there is no white plaque on the furniture or inside the appliance, and if that is not possible, use the water that has passed through the filter jug and change the cartridge in a timely manner.

Check the condition of the filters regularly if your model is equipped with them (for example, an antibacterial filter cartridge in the neck of the tank). 1-2 For months, they become a source of pollution.

Keeping the humidifier running also prolongs the life of the device: Don't leave water in the tank unless you plan to use the humidifier in the coming days. Simple algorithm: turn off, drain, dried.
