Floor fans don't actually lower the temperature of a room, instead, they circulate air which helps moisture evaporate from your skin, leaving you feeling cooler.
The best fan for you depends on your specific needs and preferences. Floor fans offer more powerful airflow than tower fans, making them ideal for commercial environments or large rooms. They are also portable, so you can circulate air from room to room where you need it most, while fitting into corners and under windows. Tower fans take up less floorspace and have a more discreet operation, making them a good choice for convenient circulation without intruding into your space.
