laundrylist 提问: What is the energy usage associated with running a cheap box fan for eight hours at night versus the two expensive models that you compared your cheaper model to?


Excellent question! I’ve wondered about that myself. The fan is 50 Watts, compared to 27-215 for an IQ Air (depending on fan speed). So they are comparable, although the IQ Air is using less energy on the lowest setting.
