An air cleaning apparatus with a moist filter is disclosed. More particularly, the present invention relates to an air cleaning apparatus with a moist filter, being operated such that: water stored in a bottom reservoir tank flows upward in a centrifugal manner; water molecules are finely cleaved in a microfine state and injected through multiple injection holes in the same centrifugal manner to become moist; under such conditions, water flowing into a rotational column, to which a centrifugal force is applied, is filtered while circulating a cycle wherein external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling ultrafine dust as well as fine dust to be filtered with high efficiency and excellent economic advantage.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a watering housing disposed in the water tank, drawing water stored in the water tank to pump water to an upper side, and spraying the pumped water; a nozzle disposed in the watering housing and spraying the pumped water; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water sprayed from the nozzle forms at least one spray line on an inner side surface of the visual body.

An air cleaner not susceptible to a decrease in effect. The air cleaner includes: a storage tank that stores a liquid; and an air blowing unit. In the air cleaner, the storage tank has an air receiving region and a dust retention region formed therein, and the air blowing unit blows air to the air receiving region. The dust retention region is a region partitioned by a wall in which an opening is formed toward an upstream side of a flow of the liquid.

An air purifier system for removing particulate matter and gaseous particles from polluted indoor air is provided. The air purifier system comprises a filtration chamber having an amount of water. The filtration chamber receives the polluted indoor air with the polluted indoor air traveling through the water leaving behind particulate matter and gaseous particles in the water and cleaned air exiting the filtration chamber. An electrolyzer continuously electrolyzes distilled water to generate hydrogen molecules and oxygen molecules in an electrolysis process with the oxygen gases added to the cleaned air exiting the filtration chamber. A fuel cell receives the hydrogen gases from the electrolyzer for generating electricity with the fuel cell electrically connected to at least the electrolyzer for at least partially powering the electrolyzer. The cleaned air exits the filtration chamber is free from particulate matter and gaseous particles.

Air filtration devices are described for wet air filtration. In exemplary embodiments, an air filtration device includes a housing having an air intake and an air outlet. An air conduit extends between the air intake and the air outlet. A fan is positioned in the air conduit and configured to draw air into the device via the air intake and propel the air through an air channel towards the air outlet. The air conduit includes a liquid introduction section configured to introduce a liquid to the air in the air channel, and a liquid removal section configured to guide the air in a downward helical path downstream of the liquid introduction section configured to separate the liquid from the air using centrifugal force.

A mobile air cleaning device for reducing air pollution emissions from a source by cleaning contaminated air is provided. The air cleaning device includes a tank to hold liquid, an extendable pipe to extend relative to the tank, an air filter to transmit air to the tank, a screen to filter pollution from the source, a pump to circulate liquid in the tank, and a liquid filter to filter pollution from the tank. The extendable pipe includes a fan to draw contaminated air through the extendable pipe to the tank where pollution emissions are captured in the liquid and clean air escapes though an air hole in the tank. A drone may deploy the air cleaning device to an elevation of the air pollution emissions. Advantageously, the air cleaning device militates against air pollution by cleaning contaminated air in a mobile and compact manner capable of reaching various elevations.

The air sterilization device with heating apparatus comprises a mainframe, a sterilization system, a heating system, circuits and a control system and a housing. The sterilization system includes an ultraviolet sterilization apparatus to sterilize and disinfect air; the heating system heats the air to inactivate virus; and the housing has an air inlet and an air outlet. Air can circulate into the housing through the air inlet with the action of mainframe and then the air is discharged from the air outlet into a room after the disinfection and sterilization processes are finished. The device with heating apparatus aims at the secondary inactivation of viruses by high temperature after the sterilization and disinfection processes are finished by ultraviolet sterilization apparatus and heating system, and at the decomposition of ozone produced in the process of ultraviolet disinfection to eliminate secondary air pollution by ozone.
