An air purifier includes a main housing, an air filter, a driving motor, a centrifugal fan, and an air outlet guider. The air outlet guider includes a central hub connected to the driving motor, a plurality of outlet guiding blades outwardly extended from the central hub, and a peripheral rim connected to the central hub at a distance from the central hub to form an air guiding cavity between the central hub and the peripheral rim. The outlet guiding blades extend in the air guiding cavity. When the driving motor is activated to draw air from the air inlet, the air is forced to sequentially pass through the filter assembly and the guiding cavity. The air in the air guiding cavity is diverted and guided by the outlet guiding blades to form a more streamlined flow which is to be discharged through the air outlet.

An air-conditioning control system includes: an enclosure with a ventilation opening; a particle sensor detecting particles; and a controller. The controller controls an amount of particles in a predetermined region, is switchable between first and second states, an amount of particles is controlled such that in the second state the particles existing in the predetermined region are reduced to be less than in the first, compares a detection value acquired from the particle sensor and a threshold in a case of the first state, performs a predetermined process based on the comparison, and in response to predetermined conditions being satisfied when in the second state, (a) acquires the detection value from the particle sensor, (b) determines a correction value based on the acquired detection value and a reference value, and (c) corrects, as targets for the comparison, either the threshold or the detection value, by using the correction value.

An air purification system for installation over a vent. The air purification system includes a housing including a rear-section having a filter-compartment; and a front-section having a set of horizontal-slats (louvers). Further, the air purification system includes a filter-receptacle removably received within the filter-compartment and configured to removably house a filter-means such as a HEPA filter. The filter-receptacle can be lowered from the housing so that a user may change or clean the filter-means, and then raised back into the housing for use. The air purification system is useful for filtering particles such as pet hair, pollen, mold, viruses, bacteria, etc. from air vented through the vent, therefore purifying air in a building.

An air purifying system includes a robot cleaner configured to generate map information during vacuum cleaning and at least one air purifier that is operated based on the generated map information. Air purifying is performed using updated map information acquired by the robot cleaner during cleaning. The at least one air purifier includes two portable air purifiers mounted on a base air purifier. The two portable air purifiers are configured to be lifted from the base air purifier and moved to separate indoor rooms. The base air purifier includes a controller that determines, based on the generated map information and other information, which rooms the two portable air purifiers should be placed in so that air purifying may be efficient.
