The conductive filter 230 may remove viruses from the harmful gas that has passed through the physical filter 220 . The conductive filter 230 may destroy the virus without passing through the electrode while the harmful gas passes. The conductive filter 230 includes a porous membrane 232 , a filter power supply unit 234 , an anode unit 236 , and a cathode unit 238 .

The porous membrane 232 is a thin membrane having a plurality of holes therein, and may be formed by foaming. The porous membrane 232 may be supported on a support or the like as a thin membrane. The plurality of holes formed in the porous film 232 may have a size of, for example, about 20 nm to 50 nm.

The anode part 236 and the cathode part 238 are disposed on the porous membrane 232 and may be formed on the top surface of the porous membrane 232 by screen printing using nano paste or the like.

The anode part 236 is electrically connected to the filter power supply part 234 and includes an anode main line 236a and an anode subline 236b.

Here, current does not continuously flow through the positive sub-line 236b and the negative sub-line 238b, and current may flow instantaneously when a virus is applied to the positive sub-line 236b and the negative sub-line 238b. As the current flows instantaneously in this way, viruses caught in the positive sub-line 236b and the negative sub-line 238b may be destroyed.

In addition, as described above, when a virus is caught in the positive sub-line 236b and the negative sub-line 238b, a minute current flows instantaneously. However, it is possible to detect whether a virus is contained in the air by detecting the minute current. .

Accordingly, when a virus comes into contact with the anode sub-line 236b and the cathode sub-line 238b, it may be instantaneously destroyed.

In addition, viruses destroyed by the positive sub-line 236b and the negative sub-line 238b may be filtered by the plurality of holes formed in the porous membrane 232 .

Therefore, as described above, fine particles and viruses are removed through the physical filter 220 and the conductive filter 230 , so that a clean gas can be discharged from the virus removal chamber 210 .
