摘要： 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.

摘要： 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.

摘要： An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) system air filter for a building ventilation system. The HVAC system air filter comprises a supportive frame configured to orient the HVAC system air filter within the building ventilation system. A composite filter medium retained within the supportive frame comprises a cotton gauze portion and an electrostatic portion. The cotton gauze portion is configured for treatment with a filter oil composition to enhance airflow and filtration of air flowing through the composite filter medium. The electrostatic portion is configured to electrostatically attract and agglomerate airborne molecular contaminants and volatile organic compounds (VOCs) as small as 0.001 microns in diameter. In some embodiments, the composite filter medium comprises substances configured to release a fragrance into air passing through the composite filter medium.

摘要： An air filtration apparatus includes a motor, a fan blade, an air filter, a housing, a filter cleaning assembly, and a control panel. A stator of the motor is concentrically mounted within the housing, and the fan blade is concentrically mounted to a rotor of the motor so that the air can be moved via the fan blade. The air filter is externally mounted to a rear panel of the housing to purify incoming air. The filter cleaning assembly is integrated to the air filter and is in fluid communication with the air filter so that the air filter can be cleaned when necessary. The control panel being electrically connected to the motor and the filter cleaning assembly to continuously operates the air filtration apparatus.
