The present disclosure relates to a double swirl type air purifier including: a main body configured to accommodate a liquid for purifying an inflow air; a suction part located at one side of the main body and configured to suction the inflow air; and a discharge part located at a predetermined position of the main body and configured to discharge an outflow air introduced from the main body. The main body includes a rotation part located at a lower portion of the main body and configured to rotate the liquid. A contact area between the liquid swirled by the rotation part and the inflow air swirled by inflow pressure of the suction part is increased so as to improve air purification efficiency.

Space purification system includes: hypochlorous acid water supplier that supplies hypochlorous acid water to mixing tank; water supplier that supplies water to mixing tank; water level sensor that detects a water level of mixing tank; air purifier that micronizes and releases, into air, mixed water of the hypochlorous acid water and the water stored in mixing tank; and air purification control unit that controls supply treatment and drainage treatment of the mixed water. Air purification control unit (i) executes first control of causing hypochlorous acid water supplier to perform supply of the hypochlorous acid water at predetermined time intervals, and second control of causing water supplier to perform supply of water based on information regarding the water level of mixing tank from water level sensor, and (ii) executes, as the control of the drainage treatment, third control of causing the mixing tank to drain the mixed water stored in mixing tank based on an integrated humidification amount in air purifier.

Disclosed is a wet air purifier that eliminates contaminants while contaminated air passes therethrough by causing the contaminated air to come into contact with water. The wet air purifier suctions external air by rotating a rotary fan installed therein and disperses water droplets by causing water to collide with a rotary fan to increase a contact surface between air and water. In the wet air purifier, a mixture of the contaminated external air and the water is made to pass through a long narrow passage and guided to a storage tank in which contaminants are settled. In this way, the wet air purifier increases a retention time and a collision time of water and contaminated air. The wet air purifier also can function as a humidifier.

Indoor air is purified using a purifying solution in an arrangement capable of removing formaldehyde and other pollutants, such as, for example, particulates. The arrangement can prevent re-vaporization of volatile compounds and can generate air that has been humidified or dehumidified. In one approach, incoming air is contacted with the purifying solution in a packed bed.

Disclosed herein is a portable air purifier. The portable air purifier includes: a body; first to third accommodation portions configured to have respective open top surfaces in order to separately accommodate a battery, an air compressor, and water; first to third covers configured to selectively open and close the respective open top surfaces of the first to third accommodation portions; an air inlet connected to the lower portion of the second accommodation portion, and configured to accommodate a pre-filter; a siphon pipe positioned upright inside the water of the third accommodation portion, and configured such that the top thereof is connected to the air outlet of the air compressor; a cannula installed on the top of the third accommodation portion, and configured to supply purified, humidified air to a user; and a power switch configured to control the amount of air to be supplied.

Disclosed are methods, apparatuses, assemblies, devices and systems for removing pollutants from air within a space or an environment. Humidifiers introduce a pollutant trapping material into the air of the space or environment by evaporating the pollutant trapping material, wherein the pollutant trapping material adheres to pollutants in the air being purified. Dehumidifiers remove the pollutant trapping material, along with pollutants adhered thereto, from the air by dehumidifying it. The cooperation of the humidifier(s) and the dehumidifier(s) may be collaborated based on a combination of pollutant concentration level value(s) and relative humidity level value(s) measured in the air.

A system and method for filtering contaminants from air has a housing assembly further comprising at least one air inlet and outlet. An intake fan assembly draws air in and propels the air through at least one tube assembly leading to a bottom portion of a removable aqueous solution tank member. A plurality of hole members lines an upper surface of a submerged portion of the tube assembly from which bubbles travel upward through an aqueous solution to a condensing chamber assembly. At least one cooling condenser coil assembly in a first duct cools the air to removing humidity and contaminants, the air then traveling to a second duct bearing a heating coil assembly. The air travels through the second duct to a dry filtration system including a removable carbon filter screen fronting the exit portion. At least one electric motor assembly and LED control assembly permits and controls operation.

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.
