In order, in the case of a device for separating ultra-fine particles (UFP) from an air flow (3) which flows in motor vehicle ventilation and climate control systems (1), to ensure a higher degree of separation for said ultra-fine particles (UFP), it is proposed that the device for separation is configured as an electrostatic separation device (8), having a collecting electrode (11), on which ultra-fine particles can be accumulated which are charged in the electrostatic separation device (8) upstream in the flow direction of the air flow (3), and that the collecting electrode (11) of the electrostatic separation device (8) is arranged in relation to an evaporator (5) of the motor vehicle ventilation and climate control system (1) in such a way that the collecting electrode (11) can be cleaned automatically by means of condensation water which is produced on the evaporator (5).

An air cleaning device for separating airborne particles from a flow of air is provided. The air cleaning device comprises a separating unit and an ionizing unit arranged to charge airborne particles present in the flow of air and transmit at least a major part of the charged particles towards the separating unit. The ionizing unit comprises at least one collector electrode and at least one emitter electrode. The separating unit is arranged to attract at least some of the charged particles so as to separate them from the flow of air. Further, the at least one collector electrode is shaped so as to conduct at least a portion of the flow of air and has a spherically curved inner surface and the emitter electrode is centered with respect to the spherically curved inner surface of the collector electrode.

The following is an apparatus and a method that enables the automated collection and identification of airborne particulate matter comprising dust, pollen grains, mold spores, bacterial cells, and soot from a gaseous medium comprising the ambient air. Once ambient air is inducted into the apparatus, aerosol particulates are acquired and imaged under a novel lighting environment that is used to highlight diagnostic features of the acquired airborne particulate matter. Identity determinations of acquired airborne particulate matter are made based on captured images. Abundance quantifications can be made using identity classifications. Raw and summary information are communicated across a data network for review or further analysis by a user. Other than routine maintenance or subsequent analyses, the basic operations of the apparatus may use, but do not require the active participation of a human operator.

An ion filtration air cleaning device for cleaning air by use of electrostatic ion attraction. Air having suspended particles is drawn into the device through an inlet by a fan. An ionization source near the inlet generates ions. Electrical charge transfers from the ions to the suspended particles. The fan pushes the air and suspended charged particles toward an outlet. A filter located adjacent to the outlet operates by electrostatic attraction and filters the charged particles from the air, allowing cleansed air to be released from the device, with a reduced level of charged particle emission
