How to Wash a Xiaomi Humidifier: A Complete Guide to Device Care

Xiaomi’s humidifier is an indispensable tool in the fight against dry air, especially during the heating season or hot summers, but even the most technologically advanced device requires regular maintenance. Incorrect cleaning can lead not only to breakage, but also to the reproduction of bacteria, which are then sprayed with the steam around the room. In this article, we will discuss how to properly wash the Xiaomi humidifier of different models (Smartmi Air Humidifier 2, Mi Air Humidifier Pro, Xiaomi, Xiaomi). MJJSQ02ZM and others), what means to use and what is better to refuse.

The manufacturer recommends cleaning the device at least once every 3-5 days when used actively, but in practice, the frequency depends on the hardness of the water and the intensity of the work. For example, if you pour distilled water, scale will form more slowly, but this does not eliminate the need for disinfection. In this article, you will find step-by-step instructions, a table of compatibility of cleaning products, and answers to frequent questions - from "can I wash in the dishwasher" to "how to remove the black plaque inside the tank."

Why it is important to clean Xiaomi moisturiser regularly

Many users underestimate the effects of a rare humidifier cleaning, while the device creates the perfect environment for microbial reproduction: moisture, warm air and organic particles from water.

  • 🦠 Bacterial pollution – Legionella, mold and other pathogens can multiply in the water and on the walls of the tank, which then enter the lungs.
  • ⚑ Breakdown of the ultrasonic membrane - scale and deposits reduce the life of a key element of the device.
  • πŸ’¨ Performance deterioration – clogged filters and nozzles reduce the intensity of vapor spraying.
  • πŸ‘ƒ Unpleasant smell – stagnant water begins to β€œbloom”, and the device spreads musty aroma around the room.

Xiaomi, in the instructions for the Smartmi Air Humidifier 2 and Mi Air Humidifier Pro models, explicitly states that using hard water without purification leads to the cancellation of the warranty for the ultrasonic membrane.

Also, if you have allergies or young children in your home, regular disinfection becomes mandatory, for example, a black plaque on the walls of a tank is not just dirt, but colonies of fungus, spores of which can cause coughing and irritation of the mucous membranes.

What you need to clean: a list of tools and tools

Before you start washing, prepare everything you need. Using inappropriate means can damage plastic or rubber seals. Here is a safe kit for the care of Xiaomi moisturizer:

  • 🧼 Soft detergent – a liquid for washing children’s dishes or neutral soap (for example, Baby Line or Ecover) is suitable).
  • 🧽 Sponge or microfiber cloth – do not use metal washcloths or hard brushes, they scratch the surface.
  • πŸ§‚ Citric acid or vinegar - to remove scale (dilute in a proportion of 1 tbsp. l. per 1 liter of water).
  • 🧴 Hydrogen peroxide (3%) - for disinfection (not to be confused with concentrated!).
  • πŸ”§ Soft toothbrush - for cleaning hard-to-reach places (for example, spray nozzles).
  • πŸ’§ Distilled water – for rinsing after cleaning.

What can't be used:

  • 🚫 Abrasive powders (Pemolux, soda in dry form) - scratch plastic.
  • 🚫 Chlorine-containing products (White) - corrode rubber seals.
  • 🚫 Concentrated acids (acetic essence) – can damage the ultrasonic membrane.
  • 🚫 Aromatic oils - leave a film, which is then sprayed with steam.

If your model has a removable filter (e.g., in the Mi Air Humidifier Pro), check the manual for its life. Usually, the filters require replacement every 2-3 months, not cleaning!

Step-by-step: how to wash the Xiaomi humidifier

The cleaning process consists of several steps: disassembly, washing, disinfection and drying. It is important to follow the sequence so as not to damage the device. Below is a universal manual that is suitable for most Xiaomi models.

Disconnect the device from the network

Drain the water from the tank.

Remove the tank from the base (if the model is collapsible)

Remove the filter (if any)

-->

Disassembly of the device

Before you start, be sure to turn off the humidifier from the socket.

  1. Pour water from the tank through a special hole (usually located at the bottom).
  2. Unplug the tank from the base.In Smartmi Air Humidifier 2 and MJJSQ02ZM For this you need to press the unlock button.
  3. If you have a removable filter in the device (e.g., a carbon filter or an antibacterial filter), remove it. The filters don't wash! They're either replaced or air-dried.
  4. In models with ultrasonic membranes (for example, Mi Air Humidifier Pro) carefully remove the spray cover.

Cleaning of the tank and the base

Start with mechanical cleaning:

  • 🧽 Pour warm water into the tank (not higher than 40).Β°C) and add a few drops of detergent.
  • πŸŒ€ Shake the tank carefully so that the solution hits all the walls. For hard-to-reach places, use a soft sponge or toothbrush.
  • πŸ” Pay special attention to the depressions and joints - there accumulates the most dirt.

If there is a limestone or black spot inside:

  • πŸ‹ Pour a solution of citric acid (1 tbsp. l. per 1 liter of water) and leave for 1 hour.
  • 🧽 After softening the plaque, gently clean the walls with a sponge.
  • πŸ’¦ Carefully rinse the tank with distilled water (ordinary water can leave a swelling).

For the base of the device (where the electronics are located):

  • 🚫 Never immerse the base in water! wipe it with a damp cloth soaked in soapy solution.
  • πŸ”Š Especially carefully clean the ultrasonic membrane (if it is open) - use a cotton swab dipped in hydrogen peroxide.
  • πŸ’¨ Blow the nozzle of the sprayer with compressed air (you can use a canister to clean the equipment).

3. Disinfection

After mechanical cleaning, you need to destroy bacteria and fungi.

  1. Prepare a solution of hydrogen peroxide (3%) with water in a ratio of 1: 1.
  2. Pour the solution into the tank and base (if possible) for 30 minutes.
  3. For an enhanced effect, you can add 1 tsp. citric acid.
  4. After disinfection, thoroughly rinse all parts with distilled water.

Drying and assembly

This is the most important step that many people miss: wet parts are the perfect environment for bacteria to grow, and you don't build the device until you dry it out.

  • β˜€οΈ Spread all parts on a dry towel in a well-ventilated place.
  • πŸ•’ Let it dry for at least 4-6 hours (better to leave overnight).
  • 🚫 Do not dry the device with a hair dryer or on a battery – this can warp plastic.
  • πŸ”Œ Before turning on, check that all seals are in place and the tank is tightly fixed.

πŸ’‘

After cleaning, make the first run of the humidifier with distilled water - this will help remove the remnants of detergents from the system.

How to clean an ultrasonic membrane and sprayer

The ultrasonic membrane is the heart of Xiaomi's humidifier. It vibrates at a high frequency, breaking water into tiny droplets. If the membrane forms scale or dirt, the device starts to work louder and the vapor becomes less intense. You need to clean the membrane carefully so as not to damage it.

Most of the models are Smartmi Air Humidifier 2, MJJSQ02ZM) The membrane is located under the removable lid at the base of the device, to reach it:

  1. Turn off the humidifier from the network and drain the water.
  2. Remove the tank and turn the base over.
  3. Carefully tuck the spray cover (usually it is fixed with latches).
  4. The membrane looks like a round metal disc – don’t touch it with your fingers or sharp objects!

For cleaning:

  • 🧴 Apply a solution of hydrogen peroxide (3%) on a cotton swab and gently wipe the membrane.
  • πŸ‹ If there is lime plaque, use a solution of citric acid (1 tsp per 100 ml of water), but do not leave it for longer than 5 minutes.
  • πŸ’¦ Rinse the membrane with distilled water by moistening the cotton-coated disc.
  • β˜€οΈ Let it dry in the air (do not wipe it!).

In Mi Air Humidifier Pro models, the membrane can be protected by an additional grid.

  1. Remove the net and wash it under running water.
  2. To clean the holes, use a toothpick dipped in peroxide.
  3. Do not try to disconnect the membrane from the base - this will lead to the loss of warranty.

⚠️ Warning: If the membrane is made to make extraneous sounds (squeaking, crackling), immediately disable the device. This is a sign of damage, and further use may cause the humidifier to fail.

What to do if the membrane stops working?
If the humidifier does not turn on or spray steam after cleaning, check: 1. Is the tank installed correctly (some models have a position sensor). 2. Has the water got on the electronic board (if the base was disassembled). 3. Is the membrane mechanically damaged (scratches, dents). In 80% of cases, the problem is solved by re-drying. If not, contact the Xiaomi service center, since the membrane is not subject to self-replacement.

Frequent problems and how to avoid them

Even with regular cleaning, users of Xiaomi humidifiers face typical problems, and let’s look at the most common ones and how to prevent them.

1. Black raid inside the tank.

This is a mold or bacterial film that is formed due to:

  • Use of ordinary tap water (it contains organic substances).
  • Long-term idle devices with water inside.
  • Inadequate drying after cleaning.

How to clean up:

  1. Prepare the solution: 1 liter of water + 2 tbsp hydrogen peroxide (3%) + 1 tbsp citric acid.
  2. Pour in the tank and leave for 2-3 hours.
  3. Clean the walls with a soft sponge and wash thoroughly.
  4. Repeat the procedure if the raid remains.

For prevention:

  • πŸ’§ Use distilled or boiled water.
  • β˜€οΈ After each use, drain the water and dry the tank.
  • πŸ•’ Clean the device every 3 days when used actively.

2. White raid on furniture

These are lime deposits that settle on surfaces with steam, especially when you use hard water.

  • πŸ‹ Add citric acid to the water (1/4 sq. 1 L water - it softens the water.
  • πŸ’¦ Use water softening cartridges (e.g. Xiaomi Mi Water Softener).
  • 🧹 Regularly wipe the furniture around the moisturizer with a wet cloth.

3. The humidifier started to make noise.

Reasons:

  • πŸ”Š Scale on the membrane - clean as described above.
  • πŸ’¨ Fan clogging - blow the nozzle with compressed air.
  • πŸ”‹ Wear of bearings (in models with a fan) - requires repair.

4.Odd smell

It's probably got bacteria in the tank, and it's going to help with a deep disinfection.

  1. Rinse the tank with a solution of vinegar (1:3 with water) and leave for 1 hour.
  2. Then pour the peroxide solution (1:1) for another 30 minutes.
  3. Dry all the details well.

If the smell is still there, it may be time to replace the filter (in models where it is provided).

FAQ: Answers to Frequent Questions

Can I wash a Xiaomi humidifier in a dishwasher?
No, it's strictly forbidden! High temperatures and aggressive detergents will damage plastic and rubber seals, and you can't wash the dishwasher thoroughly in hard-to-reach places where dirt accumulates. The maximum that can be placed in the dishwasher is a removable tank, but only on the regime of a delicate wash without drying and at a temperature not higher than 40.Β°C. Even so, the manufacturer does not guarantee the safety of the device.
How often should you change the water in your humidifier if you are not using it?
If the humidifier is idle, you need to drain the water every day, even during the day, bacteria begin to multiply in stagnant water, the best option is to drain the remaining water after use, dry the tank and store the device in disassembled form. If you plan not to use the humidifier for longer than a week, rinse it with peroxide and dry all the parts.
Why did the humidifier become worse after cleaning?
Possible causes: πŸ”Œ Incorrect assembly – check if the tank is tightly fixed and if the membrane is correctly installed. πŸ’§ Residues of detergent – wash the device with distilled water again. πŸ”Š Damage to the membrane - if cleaned with a hard brush or aggressive means. πŸ“± Settings failure – Electronically controlled models (such as the Mi Air Humidifier Pro) may need to be reset via the Mi Home app.If the problem hasn’t gone away, try running the distilled water device – perhaps the problem is water quality rather than cleaning itself.
Can I use essential oils in a Xiaomi moisturiser?
No, it's strictly forbidden by the manufacturer! Essential oils: Eat plastic and rubber seals. They settle on an ultrasonic membrane, making it less efficient. They can cause allergies when sprayed with steam. If you want to flavor the air, use a separate diffuser or add a few drops of oil to the filter (if it's removable), but not to the water!
How to store a Xiaomi humidifier in the summer when you don’t need it?
Proper storage extends the life of the device: Wash and dry all the parts (as described in the instructions above). Remove the filter (if any) and store it separately in a dry place. Pack the humidifier in the original box or wrap with a soft cloth. Store in a dry, cool place (not on the balcony or in the bathroom!). Every 1-2 months, remove the device, check for mold and if necessary repeat cleaning. Do not store the humidifier in a wet room - this will lead to the appearance of mold inside the tank.
