The disclosure relates to a wave vortex air purifier. The wave vortex air purifier according to an embodiment includes an air inhaler configured to inhale air from an outside; a liquid storage configured to accommodate liquid for collecting contaminants contained in intake air inhaled through the air inhaler; a liquid fluidizer placed inside the liquid storage and configured to rotate inside the liquid storage to rotate the liquid in the liquid storage and cause an upwelling phenomenon that a level of the liquid changes; a rotary driver configured to rotate the liquid fluidizer; and an air discharger configured to discharge purified air, from which the contaminants are removed, to the outside.

The present invention is an energy efficient air purification system 100 for purifying a complex polluted environmental air condition. The air purification system 100 includes a plurality of air pollution monitoring units MU.sub.1, MU.sub.2, MU.sub.3, MU.sub.4 . . . MU.sub.N which are installed at distant locations, a plurality of air purification units PU.sub.1, PU.sub.2, PU.sub.3, PU.sub.4 . . . PU.sub.N which are installed at distant locations and an automated control unit 500. The air pollution monitoring units are adapted to monitor the quality of the air in their surroundings. Upon such monitoring, the air pollution monitoring units are adapted to communicate the air quality data to the automated control unit 500. The automated control unit 500 is adapted to analyze the air quality data and on basis of such analysis, the automated control unit 500 further instructs the air purification units for further action.

A air inlet for an air handling unit includes an intake grate that extends around a central axis and is configured to admit an airflow therethrough. The air inlet further includes an outlet duct arranged to lie along the central axis and positioned radially inward of the intake grate. The air inlet further includes a debris collection housing.

An air conditioning and filtration system (10) comprising a pre-treatment system (12) for initially filtering air drawn from an external environment; pressurisation means (50) for positively pressurising air filtered by the pre-treatment system (12) and at least one circulation means (106). Each circulation means (106) draws air from the external environment through the pre-treatment system (12) and pressurisation means (50) as well as air from at least one enclosed area (1) for combination into an air stream. The air stream is thereafter directed to at least one set of filtration means (94) and air conditioning means (96) before being conveyed to at least one of the at least one enclosed areas (1).

A hybrid humidity control and air purification device and method for hybrid humidity control and air purification. The hybrid device is a single unit capable of humidifying dry environmental air, dehumidifying humid environmental air and removing particulates and contaminants from the air. The device controls the outgoing air to a relative humidity setpoint between 35-50% with negligible particulate matter content. Particulate matter is transferred to water, which may be supplied and flushed by an automatic water pumping system.
