Abstract:
The present invention provides an air circulation apparatus having a filter device capable of selective filtering, in which an outdoor air inflow space and an outdoor air outflow space are formed inside a case, and blower devices for forcibly blowing outdoor air are provided in the outdoor air outflow spaces. A box body having an air inlet or an air outlet is provided in either the outdoor air inflow space or the outdoor air outflow space of the air circulation apparatus, and a filter device is installed in at least one of the air inlet or the air outlet of the box body. The filter device includes a filter having a through hole passing through the center thereof, and support members for covering and supporting both sides of the filter, and has a motor-driven damper installed on any one side of the support members so as to open and close the through hole. The present invention is a very useful invention that has the effect of improving durability of the blower device and saving electrical energy by causing the outdoor air to flow indoors through the filter device only when the outdoor air quality is worse than the indoor air quality, and to flow directly indoors without passing through the filter device when the outdoor air quality is better than the indoor air quality.
