An air purification system for purifying atmospheric air has an ionization chamber that includes a needle arrangement. The needles create a dense and strong electric field when a high voltage is passed to them by the effect of dual charge ionization due to which the suspended particles in the polluted air get clumped together and fall. The second invention is an air monitoring system facilitating a two-way communication with external information sources. It contains gas sensors comprising of an ambient noise sensor, temperature and humidity sensor, and sensors to measure the amount of oxides of nitrogen, Sulphur, carbon and size of suspended particles in the air. The third invention is a theft protection module for the safe keeping of an air purification system.

An imaging system includes: a housing; an ionizer including a first electrode and a second electrode and to charge airborne particles contained in the housing; a particle filter collecting charged particles; and a controller changing an amount of a current flowing between the first electrode and the second electrode by electric discharge during a printing operation, in which the controller controls the amount of current based on a print state indicator associated with the printing operation.

The invention relates to a method and an apparatus for measuring particle concentrations in an aerosol. The apparatus comprises means (103) for driving flow (105) into apparatus (101), means (115) for electrically charging particles (109) to become electrically charged particles (123) by ions (113) produced by a charger, means (117) for removing free ions (113) which are not attached to the electrically charged particles (123), and means (119) for measuring electrical current carried by the electrically charged particles (123). The means (115) for charging the particles and the means (119) for measuring electrical current carried by the electrically charged particles (123) are dimensioned such that the means (119) for measuring electrical current carried by the electrically charged particles (123) only measures a part of a total current carried by the particles.
