How to make liquid for Xiaomi dispenser at home: 3 proven recipes

Xiaomi Dispensers – from Viomi models SE to compact Mijia Smartmi - require regular replenishment with a special liquid for disinfection, flavoring or humidifying the air. Original cartridges cost from 500 to 1500 rubles, and they are enough for only 1-2 months of active use. Meanwhile, you can prepare an analogue yourself from available components, saving up to 80% of the budget.

In this article, 3 liquid recipes for different types of Xiaomi dispensers (including models with ultrasonic spraying and other devices). UV-The lamp, the proportions for the tank, and the critical warnings about the components that are destroying the device, all of which are tested for compatibility with plastic and silicone parts of the appliances, and do not leave plaque on the inner surfaces.

Important: If your dispenser is equipped with Auto Mode (automatic spraying on the humidity sensor), home fluids may require adjustments to the sensitivity settings - this is detailed in the section about settings.

1. What liquid can be poured into the Xiaomi dispenser: composition requirements

Not all homemade solutions are safe for engineering, the basic criteria for compatibility are:

• 🔬 Neutral pH (6.5-7.5) – Acid or alkaline compounds corrode seals and corrode metal parts (e.g., in air-ionized models).
• 💧 Low viscosity – thick liquids (such as glycerol) clog the nozzle of the sprayer, leading to an error E02 (fault code in Viomi dispensers).
• 🌡️ Boiling point above 80°C-Ethyl alcohol-based liquids (strength below 70%) can evaporate too quickly, triggering false overheating sensors.
• 🚫 Without oils and fats, even essential oils in concentrations above 1% form a film on the ultrasonic membrane, reducing spraying efficiency by 40–60%.

Xiaomi officially allows only distilled water or original cartridges, but tests show that solutions based on isopropyl alcohol (70-90%) or edible vinegar (3-5%) do not damage the device when diluted properly, the main thing is to avoid chlorine, bleach and abrasive particles (such as soda).

⚠️ Note: Dispensers Xiaomi Mi Air Purifier (series) 2S/3H) They have an air quality sensor that can falsely trigger vinegar or alcohol vapors, and if you put homemade liquid on the screen, you get an error. A1, Ventilize the room and restart the device.

2. Recipe №1: Universal disinfectant liquid on alcohol (for all models)

This formulation is suitable for dispensers with UV-sterilization function (e.g. Viomi). V3) Alcohol effectively kills up to 99.9 percent of bacteria and viruses, including E. coli and Staphylococcus, while not leaving furniture to divorce.

Ingredients (per 500 ml):

• 🧪 Isopropyl alcohol (90–99%) – 350 ml
• 💧 Distilled water - 130 ml
• 🌿 Tea tree or eucalyptus essential oil – 5-7 drops (optional)
• 🧂 Glycerin (food) - 10 ml (to soften vapors)

Cooking instructions:

1. Mix alcohol and water in a glass container (do not use metal bowls - an oxidative reaction is possible).
2. Add glycerol and mix thoroughly until a homogeneous consistency.
3. Drink essential oil (no more than 1% of the total!) and shake.
4. Filter the solution through a paper filter or gauze to remove possible precipitation.

3. Recipe №2: Natural liquid with vinegar for moisturizing and removing odors

This option is ideal for dispensers used in kitchens or bathrooms, where not only hydration is required, but also the neutralization of persistent odors (for example, tobacco, fish or mold).

Ingredients (per 1 litre):

• 🍶 Apple cider vinegar (5%) – 100 ml
• 💧 Distilled water - 850 ml
• 🌿 Essential oil of lavender or lemon - 10 drops
• 🍃 Dried chamomile or mint - 1 tbsp. spoon (for tincture)

Step-by-step process:

1. Pour the grass with 200 ml of boiling water and insist for 30 minutes, then strain.
2. Mix the infusion with vinegar and the remaining water.
3. Add the essential oil and pour into the bottle.
4. Let it stand for 12 hours before use (the vinegar should completely dissolve).

⚠️ Note: Vinegar solutions cannot be used in dispensers with aluminum parts (for example, in some batches of Viomi). V1). Check the inner surface of the tank with a magnet: if it does not stick – the metal is stainless, vinegar is safe.

The benefits of this recipe:

• 🌿 Removes 85% of household odors in 1 spray cycle.
• 💰 The cost of ingredients is less than 50 rubles per liter.
• 🔄 Can be used to flush the scale tank (1 time per month).

4.Recipe №3: Aromatic liquid with long-lasting effect (without alcohol and vinegar)

If you want a liquid with a strong flavor but no aggressive ingredients, this recipe based on hydrolate (flower water) and preservative will be perfect. It is compatible with sensitive models such as the Xiaomi Mi Smart Antibacterial Humidifier.

Composition (300 ml):

• 🌸 Rose or lavender hydrolate – 200 ml
• 💧 Distilled water - 80 ml
• 🧂 Potassium sorbate (preservative) - 0.5 g
• 🌿 Sandalwood or vanilla essential oil - 3 drops

Preparation technology:

1. Heat the water to 40.°C and dissolve potassium sorbate in it.
2. Mix with hydrolate and essential oil.
3. Pour into a sterilized bottle and store it in the refrigerator.

This liquid does not require frequent replacement - it can be added to the tank up to 5 times if stored in a sealed container, the scent persists for up to 72 hours after spraying.

💡

To enhance the antibacterial effect, add a solution of 1 tablet Furacilin (crushed into powder), which will extend the life of the liquid to 2 weeks without loss of properties.

5. How to properly pour homemade liquid: step-by-step instructions

Even a perfectly prepared solution can harm the device if it is not filled properly.

1. Disconnect the dispenser from the network and remove the tank.
2. Rinse the container: 🧼 To remove plaque: 1 tbsp. spoonful of citric acid per 500 ml of water, soak for 1 hour. 🧽 Disinfection: chlorhexidine solution 0.05% (sold in a pharmacy).

Dry the tank.

Pour the liquid in.

MAX

Set the tank back up.

Hold the spray button for 3 seconds

Critical errors in the pouring:

• ❌ Liquid transfusion above the mark MAX — This leads to leakage and short circuit of the board.
• ❌ The use of tap water - calcium and magnesium salts form a plaque on the ultrasonic membrane.
• ❌ Mixing different homemade solutions - can cause a chemical reaction with the release of gas.

💡

Always check the tank's tightness after pouring: tilt it slightly - if the liquid leaks through the seals, replace the silicone pad (article for Viomi: VBX01ZM).

6.Setting the dispenser under homemade liquid

Homemade solutions can differ in viscosity and volatility from the original, so they require adjustments to the settings:

For models with sensor control (Viomi) V3, Mijia Smartmi):

1. Go to Settings. → Spray mode → Sensitivity.
2. Reduce the intensity by 1-2 divisions (e.g. High to Medium).
3. Activate the Adaptive Mode option if it is available.

For mechanically controlled models (Xiaomi Mi Air Freshener):

• Set the timer 30% longer than the standard spray time.
• Use Intermittent mode instead of Continuous mode.

If the dispenser has started to make an uncharacteristic noise (squeaking or whistling), this is a sign:

• 🔊 Nozzle clog - clean with a needle or compressed air.
• 🔊 Increased load on the membrane - reduce the concentration of oils in solution.

7. Frequent problems and their solutions

Even if you follow all the rules, you can have problems. Here's how to fix them:

⚠️ Warning: If rusty spots appear on the dispenser body after using homemade liquid, immediately disconnect the device and check the integrity of the tank's inner coating. This is a sign of corrosion that can lead to a leak of electricity. In this case, a container replacement is required (original spare parts can be ordered by code). DMF-VBX02).
