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.
The maximum noise level produced by the fan when operating at the highest speed. For comparison: a noise of 30 dB corresponds to a distinguishable whisper at a distance of 5 m, 40 dB — to human speech, and 50 dB — to the sound background in an office room. The quieter the fan runs, the more comfortable it is to use.

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.
