Disclosed is an apparatus for monitoring bioaerosols, including a capturer configured to capture bioaerosol particles in air in a capture solution; a particle sprayer configured to electro-spray the capture solution in a form of droplets such that the particles are included in at least some of the sprayed droplets; and an analyzer configured to analyze the particles, sprayed through the particle sprayer, by machine learning. In accordance with such a configuration, the droplets containing a certain amount of the particles can be continuously analyzed in real time by machine learning, thereby contributing to the improvement of monitoring efficiency for a specific bioaerosol genus.

An air purifier is provided, including a box body and a filter screen inside the box body, an air suction device, a water mist generator, the water mist generator being disposed at one side of the filter screen, the air suction device being configured to inhale outdoor air into an interior of the box body, and the water mist generator being configured to form an ionized water layer.

The invention relates to a cleaning device for cleaning a gas, in particular air, comprising: a first electrode which is populated with at least one element, preferably a plurality of elements, said at least one element having a surface with a plurality of tips and/or protrusions in order to generate a non-homogeneous electromagnetic field, a second electrode which preferably lies opposite the first electrode, and a voltage source which is electrically connected to the first electrode and/or the second electrode and by means of which a voltage can be built up between the first electrode and the second electrode.
