Best Ultrasonic Humidifiers with Large Water Tank

Among the hordes of Xiaomi partners, the Chinese company Deerma has gained very strong authority. The air humidifier from her with the model index DEM-F327 has an original external design and fits perfectly into modern room interiors (up to 30 m²).

To generate cold water mist, the device uses a high-performance ultrasonic emitter with a durable membrane. The intensity of the transfer of moisture into a vapor state is adjusted manually or automatically - according to the readings of the built-in hygrometer with the ability to set the desired humidity level from 45 to 90%. The water supply in the 5-liter humidifier tank is enough for 16 hours of continuous operation.

The technological feature of the device is a built-in UV lamp for disinfecting indoor air from viruses, fungi and bacteria. The model also has an aromatization system - a special retractable compartment into which aromatic oils drip. And you can add flowers or pieces of fruit to the humidifier reservoir, which also give an aromatherapy effect.

The model is characterized by low-noise operation; it also provides the ability to turn off the display backlight and touch buttons so as not to disturb night sleep. The device shutdown timer is set at intervals from 2 to 10 hours. The only complaint is the glass bulb of the device, which can become cloudy over time. However, this is mostly due to the quality of the water used - if you take it from reverse osmosis filters, then the problem is reduced to nothing.

The WetAir WH-605B model combines the capabilities of several devices in one bottle. First of all, it is an ultrasonic air humidifier with advanced functionality, and secondly, it is a home weather station.

In the humidification mode, the operation of the device is adjusted automatically - thanks to the presence of a hygrometer in the equipment, the humidity level is increased to a preset level. The user is given three options for the intensity of air mass humidification to choose from. In maximum performance mode, WetAir WH-605B consumes up to 300 ml of water per hour. A full tank with a volume of 4.5 liters is enough for approximately 15 hours of non-stop operation of the device. When the tank is empty, humidification automatically stops.

The device was equipped with a convenient touch control panel and a digital LED display for displaying the humidity level, room temperature, operating modes, and setting a delayed shutdown timer. One of the interesting features of the model is the ability to display humidity and temperature readings “in idle mode,” i.e. without using the air humidification function.

A ceramic filter cartridge is installed inside the device, which softens hard water and prevents the formation of all kinds of deposits. After turning off the device, the drying function is activated, which helps to avoid the growth of fungi and mold in the ventilation duct. Finally, WetAir WH-605B implements an ionization mode - saturating the air with negatively charged particles, which have a beneficial effect on the health and well-being of people in the room being served.

There’s just so much that Xiaomi’s huge portfolio doesn’t have. In 2023, the Chinese guys from this company even managed to introduce an electric car. However, in the more mundane segment of climate control technology, brand humidifiers are very popular. In particular, the Smart Humidifier 2 model.

The device is housed in a barrel-shaped case made of white matte plastic. An outlet valve for spraying water mist can be seen on the top of the housing. It is equipped with a regulator to limit the flow and control the direction of release of the smallest particles of water. The device’s tank holds 4.5 liters of water - at minimum fan speed, a full “refueling” lasts for about 32 hours. An external scale allows you to visually monitor the fill level of the tank.

The model not only maintains a given level of humidity, but also sterilizes the air using a built-in UV lamp. And an aromatherapy diffuser saturates the room with the pleasant aromas of essential oils. The device provides a quiet night humidification mode and has a body lighting function - the device will serve as an excellent alternative to a bedside night light.

Xiaomi Smart Humidifier 2 is equipped with a top water filling system, intuitive push-button controls, and most importantly, the model can be integrated into the smart home ecosystem. Remote control of its functions is carried out through the Mi Home application. From a smartphone it is much more convenient to control the parameters and configure the humidifier’s operating scenarios in your own way

Modern humidifiers often have a whole arsenal of functions that are easy to get confused about. It’s the same with Gorenje H45W - the model performs high-quality humidification of air masses and pleases with its ease of use.

The device is assembled in an oblong white case with beveled edges. Inside there is a 4.5-liter water tank with a convenient top fill and a clear measuring scale. You can fill the tank directly from the faucet tap in the kitchen sink. And when the tank is empty, the humidifier turns off automatically. However, you definitely won’t have to add water to the tank often.

The operation of the device is controlled by a single touch button, by tapping which one of two modes of humidification performance is set. Also under it there is an “empty tank” indication. The device does not provide any screen or additional operating modes. As a result, Gorenje H45W is not able to maintain the specified humidity parameters automatically.

The model releases water vapor through an evaporator spout that rotates 360°. The fan for spraying a cloud of tiny droplets of water produces a noise level of no more than 38 dB - the device will not disturb the light sleep of household members even in the quiet of the night. It is optimal to use a humidifier from Gorenje to service a “square area” of up to 20 m². However, it is advisable to separately acquire a hygrometer or a room weather station to control the level of humidity in the room.

Climate control equipment from Cooper&Hunter has won the hearts of users in many parts of the world. The CH-2550T Grenada ultrasonic air humidifier from the brand’s portfolio maintains normal humidity levels in domestic and office spaces up to 30 m².

The model pumps the required level of relative moisture content and maintains it automatically. The current humidity value is displayed by two numbers on the info display in the front panel of the device. The unit's on-board hygrostat is set to maintain humidity in the range of 45% to 65%. The model's tank holds 5 liters of water, which is poured from above. When spraying water mist at a rate of 250 ml/hour, a full tank of water is enough for approximately 20 hours of non-stop operation of the humidifier.

The device controls are represented by touch buttons with intuitive icons. By tapping on them, you set the level of water vapor spray performance, set the auto-shutdown timer, turn on the sky-blue backlight of the case and the night mode of operation of the device. All indications are turned off in night mode so as not to disturb the light sleep of household members. Also, the humidifier operates almost silently.

The design of the Cooper&Hunter CH-2550T Grenada included an aroma capsule into which essential or aromatic oils are supposed to be added. In parallel with humidification, the device saturates the air in the room with pleasant odors. From the spout of the device, aromatized water vapor is sprayed 360°, which ensures uniform maintenance of the required level of humidity in all corners of the “square” being served.
