This is an Iris Ohyama circulator fan. Used for about 3 years. Used it until recently. Selling due to moving. The sound is very quiet on the low setting, so it can be used while sleeping. The following is quoted from Amazon: ● This is a compact circulator fan with powerful airflow. ● It has a quiet mode and operates at less than 35dB. ● The straight, powerful airflow circulates air in the room, improving cooling efficiency in the summer and heating efficiency in the winter, making it usable year-round. ● It can reduce temperature settings, leading to lower power consumption and energy savings. ● It has an automatic left-right oscillation function. ● It has 3-stage wind speed adjustment and vertical angle adjustment from 90 degrees up to 20 degrees down. ● Designed with safety in mind, it's difficult for fingers to reach the blades to prevent accidents and injuries. In addition to circulating air in the room, it can also be used for drying laundry, ventilating rooms, and sending air to adjacent rooms. ※ I cleaned it as best as I could, but I couldn't remove the propeller, so dust has accumulated on the inside. Please refrain from purchasing if you are concerned about this.
