How to clean the air humidifier Xiaomi: instructions with photos and tips

Why do you need regular cleaning of Xiaomi moisturizer?

Xiaomi air humidifiers (such as Smartmi Air Humidifier 2, Mi Air Humidifier Pro or Deerma) DJ09C) It's become an integral part of a smart home for many users, but few know that untimely cleaning can turn it from an assistant to a source of problems, from bad smell to bacteria and mold. Inside the tank and on the membrane of the humidifier, a biofilm is formed over time - an accumulation of microorganisms that not only spoil the air, but can also cause allergic reactions.

The manufacturer recommends cleaning the humidifier every 3-5 days with daily use and doing deep disinfection every 1-2 weeks. But why is this so important? First, Xiaomi uses ultrasonic technology in its models, where water is sprayed through a vibrating membrane. If it accumulates sediments, the hydration efficiency drops by 30 to 40 percent. Second, in standing water, the bacterial count increases by 1,000 times in 24 hours, according to microbiological research. And finally, ignoring the cleaning leads to breakage: For example, in models with hygrosate (Smartmi Air Humidifier) 2S) humidity sensor may fail due to the raid.

In this article, you will find step-by-step instructions for cleaning all types of Xiaomi humidifiers (including models with flavoring function), as well as learn which products are safe for the membrane and which are not.

Preparation for cleaning: what will be needed?

Before you start cleaning, make sure you have everything you need on hand. Standard tools are enough for the basic procedure, but specialized formulations may be needed for deep disinfection. Here is the full list:

• 🧼 Soft sponge or microfiber cloth (does not scratch plastic).
• 🧴 Vinegar 9% or citric acid (to remove scale).
• 🧪 Hydrogen peroxide 3% or chlorhexidine (for disinfection).
• 🧽 Toothbrush (to clean hard-to-reach areas, such as ventilation holes).
• 💧 Distilled water (for rinsing after cleaning).
• ⚠️ Gloves (protection of the skin from chemicals).

❌ What can't be used:

• 🧹 Abrasive sponges or powders (damage membrane and plastic).
• 🧴 Chlorine products (White, Domestos) - destroy seals.
• 🔥 Boiling water (deforms plastic parts).
• 🧼 Dishwashers with aggressive surfactants (can remain on the membrane and get into the air).

If your humidifier model supports fragrance (Smartmi Air Humidifier 2 with essential oil compartment), prepare a neutral detergent (like Baby Line) to clean the aromacapsule, otherwise the oil residues will mix with the plaque and create a sticky film that will be difficult to remove.

Step-by-step: how to disassemble and clean the humidifier

The cleaning process starts with the device being disassembled correctly. In Xiaomi models, the design is usually intuitive, but there are nuances. For example, in Mi Air Humidifier Pro, the tank is separated from the base by a counterclockwise turn, and in Deerma, the tank is separated from the base by a counterclockwise turn. DJ09C — You can press the latches on the sides, and if you don't follow the instructions, you can break the latches.

Step 1: Turn off and drain water

1. Turn off the humidifier from the socket and let it cool for 10-15 minutes (if it was working at maximum power).
2. Pour the water through a special hole (in Smartmi models it is located on the side of the tank). Do not tilt the device strongly - water can get into the vents.
3. Wipe the outer surface with a wet cloth to remove dust.

Step 2. Disassembly

• Remove the tank from the base (in most models it just goes up).
• Remove the membrane (in ultrasonic humidifiers it looks like a round disc). In Xiaomi Mi Air Humidifier 2 models, the membrane is attached to the latches - gently tuck it on the side.
• If your model has a filter (e.g., coal filter in Smartmi Air Humidifier) 2S), Take it out and check for wear.

Step 3: Cleaning the reservoir and base

1. Pour warm water into the tank (no more than 40).°C) and add 2-3 tbsp. l vinegar or 1 tsp. citric acid. Leave for 30-60 minutes to dissolve the scale.
2. Clean the walls of the tank with a soft sponge. For hard-to-reach places (such as around the sprayer), use a toothbrush.
3. Clean the base with a wet cloth soaked in a solution of vinegar (1:1 with water). Pay attention to the ventilation holes - there the dust accumulates.

Step 4: Cleaning the membrane

The membrane is the most delicate part of the humidifier, and it can't be rubbed with hard objects or soaked in aggressive solutions.

1. Wash the membrane under running water, removing visible deposits with your fingers (without pressing!).
2. Submerge it in a solution of hydrogen peroxide (3%) for 10-15 minutes for disinfection.
3. Rinse with distilled water and dry on a napkin (not under direct sunlight!).

💡

If the membrane is yellowed or deformed, it needs to be replaced. In Xiaomi models, the original membranes last 1-2 years with proper care.

Step 5: Disinfection

After mechanical cleaning, you have to destroy the bacteria.

• Pour into the tank a solution of chlorhexidine (1 tbsp. l. per 1 liter of water) or hydrogen peroxide (2 tbsp. l. per 1 liter of water).
• Turn on the humidifier for 5-10 minutes in maximum spray mode (no membrane!).
• Pour the solution and thoroughly rinse all the details with distilled water.

Step 6: Assembly and Test Launch

After cleaning:

• Dry all parts in the air (do not use a hair dryer or microwave!).
• Collect the humidifier in reverse order, make sure the membrane is in place without skewing.
• Pour distilled water and turn on the device for 10-15 minutes. If you have an unpleasant smell, repeat rinsing.

💡

Never use tap water after cleaning – it contains salts that immediately form a new plaque on the membrane.

How to clean a humidifier with aromatization function?

Xiaomi models with a compartment for essential oils (Smartmi Air Humidifier 2, Mi Air Humidifier Pro) require special care. The oils leave a sticky coating that mixes with the dust and creates a breeding ground for bacteria. If you do not clean the aromacapsule, after 2-3 weeks, you will have a persistent musty smell.

Instructions for cleaning the aroma compartment:

1. Remove the oil capsule (usually located on the top panel or side).
2. Wash it under warm water with a neutral detergent (such as Baby Line or Ecover).
3. To remove the residues of oils, use a cotton swab dipped in an alcohol solution (vodka or isopropyl alcohol 70%).
4. Dry the capsule in air and wipe with a dry wipe before next use.

⚠️ Warning: Do not add essential oils directly to the water, this will break the membrane.

Top.-5 Mistakes in cleaning Xiaomi moisturiser

Even experienced users sometimes make mistakes that cause a device to break down or cause air quality to deteriorate, and the most common of these are:

1. Tap water for rinsing: tap water contains salts and chlorine that settle on the membrane immediately. After cleaning, always use distilled or filtered water.
2. Clean the membrane with a hard brush, and the membrane is made of a thin vibrating material that is easily damaged, and you just rinse it under a stream of water without pressing.
3. Ignoring filters, in models with coal or HEPA-Filters (Smartmi Air Humidifier) 2S) They need to be replaced every 3-6 months!
4. Storage of the humidifier with water inside. If the device is not used for more than a day, drain the water and dry the tank. In standing water, mucus forms in 48 hours.
5. Aggressive chemicals: Mole or Sanita-type agents corrod plastic and rubber seals, and use only vinegar, citric acid, or specialized moisturizers.

⚠️ Attention: If after cleaning the humidifier begins to make extraneous sounds (squeaking, crackling), most likely, the membrane is installed incorrectly or damaged:

• Turn off the device.
• Check the position of the membrane (it should lie flat, without distortions).
• If the sound has not disappeared, replace the membrane - its cost for Xiaomi models is 300-800 rubles.

Cleaning tools: what to choose?

There are many humidifier care products on the market, but not all of them are suitable for Xiaomi models.

🔍 Expert advice: For models with an ionizer (Smartmi Air Humidifier) 2S) Avoid perfumes, which settle on ionizing plates and reduce their effectiveness. + hydrogen.

If you prefer off-the-shelf solutions, look at Top House or Bork, which are certified for ultrasonic humidifiers, but you can use vinegar or citric acid to clean your day.

How to extend the life of Xiaomi humidifier?

The average lifespan of Xiaomi humidifiers is 3-5 years, but with proper care, this time can be extended to 7-8 years.

• 💧 Use distilled or filtered water, which will reduce scale formation by 90%.
• 🔄 Change water daily, even if the humidifier is not working. Standing water becomes a breeding ground for bacteria within 24 hours.
• 🌡️ Store the device in a dry place at a temperature of 5-35°Avoid direct sunlight – it destroys plastic.
• 🔋 Don't turn on the humidifier at maximum power all the time. Optimal mode: 60-70% of the maximum.
• 🛠️ Perform a deep cleaning once every 2 weeks, even if the external device looks clean.

⚠️ Attention: If your humidifier starts spraying water unevenly (for example, only on one side), this is a sign of a clogging of the sprayer:

1. Turn off the device and drain the water.
2. Remove the top cover of the sprayer (in Xiaomi models it usually unscrews counterclockwise).
3. Wash the sprayer holes with a toothpick or needle soaked in alcohol.
4. Blow the holes with a hairdryer at minimum power (cold air!).

If the problem recurs, check the water level in the tank – in Smartmi models, when the pump is low, the pump starts to work to wear, which leads to uneven spraying.
