The 'total heat exchange ventilator' developed to solve these problems supplies fresh outside air that has passed through the filter into the room, and at the same time removes the heat energy taken from the outside when polluted indoor air and CO₂ are discharged to the outside. The energy loss is minimized by recovering it through the 'device' and supplying it back to the room.

In general, in the existing 'total heat exchange ventilator', a pre-filter that filters out large dust is installed in front of the total heat exchange element in the OA area where outdoor air flows in to prevent contamination or clogging of the 'total heat exchange element' where heat exchange occurs. One is installed in front of the total heat exchange element in the RA area where indoor air flows in, and a HEPA filter for fine dust is installed in the direction of the OA and SA passages.

In principle, the HEPA filter should be replaced after a certain period of use, but the pre-filter has the advantage of being able to be used repeatedly semi-permanently if it is cleaned regularly. However, when the contaminated pre-filter is cleaned indoors with a vacuum cleaner, a lot of dust blows on the floor or around, and when cleaned outdoors, there is a hassle such as having to take the vacuum cleaner outdoors to clean it.
