We decided to create one of the best whole house fan ranges that can expand the role of air power in modern home living. By improving the concepts of controlling air behaviour, such as the Conda effect, particle filtration in the air and thermal convection, and combining them with modern technologies such as brushless motors, newer airflow systems and PTC plates, Dreo is committed to developing the most professional, energy efficient tower fans available.
