In the perspective of saving energy in buildings, the high performance of insulation and air tightness for improving the heating and the cooling efficiency, has brought economicaliy positive effects. However, these building energy saving technologies cause the lack of ventilation, which is the direct cause of increasing the indoor contaminants, and is also very harmful to the residents, because they spend over 90% of their time indoors. Therefore, the ventilation is important to keep the indoor environment clean and it can also save the energy consumption. In this study, a HEPA type nano ceramic filter is designed as a passive ventilation system to collect airborne particles and to supply fresh outdoor air. The double layer filter, which has 30㎛ in diameter at the conditions of 10wt% of concentration and 3kV/cm of the electric intensity, is produced by electrospinning. The filtration coating technology is confirmed in the solution with SiO₂ nano particles using polymer nano fibers. Also double layer filters are coated with SiO₂ nano particles and finally the porous construction materials are made by sintering in the electric furnace at 200～1400℃. The efficiency is measured 96.67% at the particle size of 0.31㎛, which is slightly lower than HEPA filter. However the efficiency is turned out to be sufficient.
