An air treatment apparatus includes: a heat exchanger that exchanges heat between a fluid flowing through a first flow path and air flowing through a second flow path; and a first dust collector disposed upstream of the heat exchanger in a flow of the air and that collects a substance contained in the air flowing to the heat exchanger. The first dust collector has: a surface over which water flows, or a surface on which water is retained.

A humidification and air cleaning apparatus is provided, in which a first sweep angle and a second sweep angle are formed at diffuser blades, and an included angle is formed between the first sweep angle and the second sweep angle, such that a phase difference is formed in air passing through the diffuser blades, and thus, air flow noise may be reduced.

Disclosed are a capture device for purifying air, a purification device, and an air purifier. The capture device for purifying air includes: a housing and a capture assembly. The housing is provided with an air inlet and an air outlet, wherein a cavity, in communication with the air inlet and the air outlet, is defined inside the housing; and the capture assembly is arranged in the cavity, and is located between the air inlet and the air outlet. The capture assembly includes a first rotating disk, a second rotating disk and a cylinder, wherein both the first rotating disk and the second rotating disk are rotatable and rotate in opposite directions; and the cylinder is disposed between the first rotating disk and the second rotating disk.

An air monitoring system having a device which captures air contaminants, particularly biological particles, particularly viruses, more particularly SARS-CoV-2 is provided, and to methods associated with the system for sampling and detecting them in the air but also for digesting the captured biological particles by bio-oxidation through a microorganism compound additive. The invention also relates to kits of parts having the device and at least a test, preferably an antigen test cassette as well as to their use in detecting said biological particles within the air.

An energy-efficient, space-saving, low-cost, waste-heat-utilizing ventilating air conditioning apparatus uses a honeycomb rotor having a function of adsorbing or absorbing contaminants such as carbon dioxide and VOC gas. The honeycomb rotor is disposed in a rotor rotating device having at least a processing zone and a re-generation desorption zone. Air to be processed is passed through the processing zone to remove contaminants such as carbon dioxide to produce supply air. Water is directly sprayed or dropped into a heat exchanger provided at an entrance of the re-generation desorption zone to evaporate the generated water film by heating. The generated saturated steam is introduced for desorbing carbon dioxide and pollutants, and the stream is discharged the stream outdoors. The ventilating air conditioning apparatus can operate without the energy loss associated with ventilation.

A humidifying air purifier includes a door assembly supported and configured to be selectively drawn out of a front side of a cabinet and drawn into the front side of the cabinet to respectively open and close an inner portion of the cabinet. The door assembly includes an accommodation portion configured to support an air filter and a humidifying device which are both drawn out of and into the humidifying air purifier with the door assembly.

It is an Evaporative Humidifier Air Purification combo unit performing the functions of both cool mist evaporative air humidifier as well as the air purifier. The optional attachments make it easy for the consumers to make use of any of the functions it is capable of performing. It even solves the problem of degradation of performance and material life prevalent in conventional standalone air purifier units. The evaporative humidifier is motor driven and is provided with proprietary HEPA quality nano membrane with high chemical stability, waterproof, water vapor permeability, windproof, breathable, acid and alkali resistant, anti-corrosion and anti-bacteria functions etc. membrane used in combination with humidifier cooler pads. On using the water tank, the setup performs the function of air humidifier using the air sucked from the wick using the fan and aiding the evaporation of water in the tank. While on replacing the water tank with the air cover, the same fan sucks air through wick and blows the purified air upwards in consonance to the mode i.e. High, Medium or Low.
