Smart antibacterial moisturiser Xiaomi Mi: where to drip essential oil

Owners of climate technology often wonder about expanding the functionality of their devices. Xiaomi’s smart antibacterial humidifier creates the perfect atmosphere, but adding flavors requires strict compliance with operating rules. Incorrect use of essential oils can lead to the failure of expensive equipment and loss of warranty.

The main problem is the design of the evaporative element. Most budget and mid-range models, such as the Xiaomi Mi Smart Antibacterial Humidifier, are equipped with ultrasonic membranes that are sensitive to aggressive chemical compounds. Direct hit of concentrated oil on the filter or in the tank of water causes the structure of the material to collapse.

In this article, we'll look at the technicalities of air fragrance, whether there are special compartments in your model, and how to safely enjoy aromatherapy without risking damage to electronics, and it's important to understand the difference between conventional and specialized models.

Design features of ultrasonic humidifiers

The device is based on high-frequency vibrations in the membrane, which breaks water into microscopic particles. Ultrasonic technology is highly susceptible to fluid viscosity. Essential oils have a dense structure that, when in contact with a vibrating surface, creates excessive friction and heating.

Most Xiaomi models have only one primary water tank as standard. Engineers are betting on vapor purity and antibacterial treatment using silver ions or UV lamps, but not on mixing liquids. Trying to add flavoring directly to the tank violates the physicochemical properties of water.

⚠️ Attention: Direct addition of essential oils to the main tank of the ultrasonic humidifier leads to the dissolution of the plastic and destruction of the hydrophobic filter coating.

Some users ignore this fact by relying on the strength of the materials, but the polymer compounds used in the tanks can react with the components of citrus or coniferous tree oils, causing the plastic to become cloudy and produce a persistent unpleasant odor that cannot be washed away.

In addition, the oil film that forms on the surface of the water prevents normal vapour formation, the ultrasonic membrane starts to work with an overload, trying to break through this barrier, in the long run, this reduces the life of the engine and leads to premature failure of the device.

Special models with aromatization function

Not all devices lack the ability to flavor. Xiaomi engineers have released a number of models that initially include the possibility of using aroma additives, such devices provide a separate compartment, isolated from the main tank.

It's usually a small capsule or tray, located near the vapor outlet or at the bottom of the case, and in this container, a special cartridge or a few drops of oil is placed on the absorbent sponge, and the steam passes by this element and carries the fragrant molecules away without contacting the main body of water.

If you're planning to buy a new device, note that there's an Essence or Aroma label in the model name. For example, some versions of the Xiaomi Smartmi Evaporative Humidifier (evaporative) have a built-in slot for aroma cartridges. In evaporative models, the risk of damage is lower, because there's no ultrasonic membrane, but the way it works is different.

For owners of ultrasonic models of the Mi Antibacterial series, the situation is more complicated, in 95% of cases, they do not have a separate compartment, and manufacturers deliberately abandon this function in the basic models to ensure the long life of the main filter element and membrane.

Why you can not pour oil in the main tank

The chemical composition of essential oils is aggressive against materials used in the manufacture of household appliances. Solvents contained in oils can erode rubber seals and plastic compounds, which leads to loss of leakage and water leakage to electronic components.

Another problem is the change in surface tension of the water, and the oil creates a film that prevents the ultrasonic wave from effectively breaking water, and as a result, the device's performance drops, and its energy consumption increases, the membrane begins to vibrate idle, which leads to overheating.

Also worth mentioning is health. Ultrasound not only crushes water, but also all the impurities in it. If you pour oil into a tank, the device will spray microscopic droplets of pure oil into the air. It can be dangerous for the airways, especially for allergic people, children and pets. The concentration of substances in the air will become unpredictable.

The manufacturer's warranty obligations are voided in such cases, service centers can easily determine the cause of the breakdown by the characteristic smell and condition of the internal components, repairs will cost more than buying a separate flavor.

Safe Alternatives and Aromatization Methods

If your Xiaomi Mi Antibacterial Humidifier model doesn't have a special compartment, it doesn't mean you should give up on pleasant smells. There are proven methods that won't harm the technique. The easiest way is to use external flavors.

You can drop a few drops of oil on a cotton-coated disc and put it next to the humidifier's outlet (but not inside!) The airflow will carry the scent into the room. However, make sure that the disc does not completely block the steam outlet.

Another option is to use special aroma cartridges if they are compatible with your model. Some third-party manufacturers release inserts that are mounted instead of regular filters or in special slots. But for antibacterial models, this is often impossible because of the unique shape of the filter.

The best solution for owners of ultrasonic humidifiers without aroma function is to buy a separate ultrasonic diffuser, which is a small device designed specifically for oils, which are inexpensive, consume little energy and create beautiful lighting.

⚠️ Warning: Never attempt to modify the humidifier body by cutting holes to install homemade oil capsules.

Care of the device when using fragrances

Even if you use the permitted fragrance method (through a separate compartment or an external diffuser), the maintenance of the machinery requires attention. Oils have the ability to oxidize and form a sticky plaque, which can settle on nearby surfaces and parts of the device.

Regular cleaning is required, once a week, you should wipe the body and the exit holes with a soft cloth soaked in a weak soap solution, and then wipe dry, which will prevent the accumulation of dust that mixes with the oil and turns into hard-to-remove dirt.

If you do venture to add oil to the tank (which we strongly recommend), the only way out is to thoroughly flush the system, you need a lot of warm water and a mild detergent, but the warranty will be lost forever.

Use citric acid or special tablets to clean humidifiers to disinfect the tank. Chlorine-containing products should not be used, as their vapors are harmful to breathing, and residues can damage the plastic.

💡

Use only 100% natural essential oils. Synthetic flavors contain alcohol and aggressive solvents that break down plastic faster than natural counterparts.

It is safer and more efficient to use a separate aroma diffuser than to risk breaking the main humidifier.
