Abstract
A fan is for improving air quality, such as in an indoor environment. The fan includes a motor and a rotatable hub coupled to the motor. At least one fan blade includes a first end portion coupled to the rotatable hub and a second end portion radially distant from the rotatable hub. At least one ion generator is carried by the second end portion of the at least one fan blade, such as by a winglet associated therewith. A stationary tube passes through the rotatable hub including a conduit for transmitting power. A rotary coupling is also provided for transmitting power from the conduit to the at least one ion generator.
