It is said that the above ozone concentration is required, but with the air volume of a general electric air cleaner during normal operation, ozone is generated only from about 0.05 ppm from the ionizer, and
If a high output ozonizer or an ultraviolet ozonizer is used together, ozone of 0.5 ppm or more can be generated, but in order to reduce the indoor ozone concentration to 0.1 ppm or less of the environmental standard value, ozone that adsorbs a large amount of ozone The adsorption part becomes indispensable.

大きい。As is apparent from the above description of each embodiment, the present invention reduces the number of revolutions of the blower,
Also, without increasing the amount of ozone generated using an ozonizer, etc., the air flow rate is reduced to 1/10 or less of that in normal operation, and the ozone concentration is increased to 10 times or more that in normal operation to sterilize the collected bacteria with ozone. Therefore, the collected bacteria do not propagate at the dust collection electrode part, and there is no possibility of re-scattering into the hospital room or worker contact with bacteria during maintenance, providing an air purifier with high safety. Is possible. Moreover, since the amount of ozone generated is small, it is not necessary to use the ozone adsorption part, and the use of a small ozone adsorption part enables ozone sterilization that does not emit ozone semipermanently. It can be used as an electric air purifier that does not have any, and its value is great, for example, as an air purifier for hospitals.
