Comparison AEG VL 5569 S LB vs UFO ATSFI-121

The maximum power consumed by the fan during operation. The higher the power consumption, the higher, usually, the greater the airflow rate created by the fan, and, accordingly, the higher the performance of the device. On the other hand, power usually directly affects the price, all other things being equal.

— Stepless adjustment. The ability to adjust the rotation speed when a slider is used instead of several buttons. In this case, you can set the speed not step by step, but over a wide range.

— Oscillation. Thanks to the oscillation, the fan can change the direction of the airflow horizontally, while remaining stationary. The direction can be set manually, and it can also change automatically when the fan constantly changes direction. Fans with small blade diameters usually do not have this capability.

— 3D rotation. Automatic rotation is assumed not only in the horizontal plane but also vertically. The implementation of this function is different: horizontal and vertical movements can be alternated, or the head of the fan can make spherical movements. Fans with 3D rotation are better at mixing air, and when used in conjunction with an air conditioner, better cooling efficiency is achieved.

— Night mode. Designed to reduce noise levels, fans in this mode reduce the speed to a minimum and periodically turn off the rotation of the blades. Note that in this mode you will have to sacrifice the power of the fan, and in hot weather, this mode may not be relevant.

— Wind imitation. This mode periodically changes the speed of rotation of the blades, sometimes turning them off a...ltogether, creating gusts of wind. Different manufacturers call this mode differently: comfort mode, breeze mode, natural, and the like, but they all serve the same purpose.

— Height adjustment. The ability to change the height of the fan manually. Provided, usually, in floor standing models.

— Tilt adjustment. The ability to change the tilt angle of the airflow vertically. In the vast majority of models, it is set manually, but some models can change it automatically. Simple and inexpensive models often lack this capability.

— Timer. A device that automatically turns off the fan after a certain time set by the user. The presence of a timer allows, for example, to turn on the fan at night and go to bed — the device will turn itself off at the right time.

— Remote control. Possibility to control the fan from a distance. Advanced fan models are equipped with remote controls that allow you not only to turn the device on and off but also to adjust the speed and set the timer value.

— Control via smartphone. Fans that support this feature can connect to your home Wi-Fi network and be controlled directly from your phone app. Also, some models can be integrated into smart home systems to perform certain scenarios. There are models in which this function completely replaces the remote control.

— Humidification. Fans with this function are a hybrid of a classic fan and a humidifier. They have a reservoir with water and a device that supplies water vapour to the fan blades, where it is carried around the room by airflow. In general, such a combination is more effective than classic humidifiers, as it provides the evenest distribution of moisture. However, fans with humidification are quite rare.

— Ionization. The presence of a built-in air ionizer. It is believed that air saturated with negatively charged oxygen ions is extremely beneficial for health. Not all fan models (even expensive ones) are equipped with an ionizer. However, it can also be purchased separately.

— Built-in lamp. The presence in the ceiling fan of the LED panel or lightbulb sockets. This option allows one device to replace both the chandelier and the fan.

— Clip mount. Such a device allows fixing the fan on the edge of the wall shelf opposite the face, which will not only create a more pleasant air flow but save space on the desktop surface (and even on the shelf where the fan is installed). In addition, such a mount is more reliable than a simple installation on a horizontal surface — overtiping a fan with a clip mount is much more difficult than a fan standing on a desktop or a shelf.

— Display. A small screen designed to display various service information. The display can show data on the operating mode, the set timer, the time until the fan is turned off, etc. The display makes fan control more convenient, but other things being equal, such devices are usually more expensive.

Quiet fan operation mode with reduced noise. It is achieved by reducing the rate of rotation of the blades and their periodic shutdown. In night mode, the fan operates almost silently, without disturbing the sleep of the household. However, due to the reduced airflow in hot weather, the cooling efficiency drops.

Volume of the water tank installed in the fan with humidification function. A large capacity allows you to work longer without refilling, but it affects the dimensions and weight of the device. However, uptime also affects performance. Often devices have several modes for more comfortable humidification.

— Cross base. The most common type of base for floor-standing fans, it provides sufficient stability while maintaining a lightweight design. Also, fans with a cross base are usually cheaper than others. Of the advantages, a collapsible design can be noted, which creates additional convenience for storage or transportation.

— Disk base. This type of base is massive, usually, such discs at the base can weigh 3-5 kg, depending on the fan model. They are made from various materials. Usually, the disk comes as a separate part of the structure, on which a decorative overlay is put on top. It is believed that such a base provides better stability than many cross bases.

— Tripod. The least common type of base, in which, apart from the aesthetic component, there is nothing else. In terms of structure, such models are too voluminous, and in terms of reliability, they are at the level of models with a disk.
