A device and process to inactivate viruses and kill living bacteria using the available techniques like UV irradiation, heat, filtration, and/or chemical treatment, individually or all at once to achieve the best results. The operation of the invention could be programmed/controlled using a remote controller/programmer. The invention could be used in spaces occupied by humans or when humans are not present. When humans are not present it uses mainly UV irradiation, and when humans are present it circulates the air to be disinfected through a protective enclosure. In some applications using UV disinfection, the device can circulate and disinfect the air inside it, while irradiating the UV irradiations to other parts of the space to disinfect them. One embodiment of the device is similar to a mask, not just to collect the viruses and bacteria, but also, to inactivate the viruses and kill the bacteria. The invention will make indoor places very safe and safer than outdoors, because the indoor could be disinfected as a controlled enclosed space, while the outdoor is practically impossible to disinfect. Which will allow people to live better life without fears of contracting or spreading the viruses now or in the future. The invention is easy to install, operate, maintain, clean, and highly effective.

A system and related method for air filtration and therapeutic relief are provided. The system includes a base layer, a substrate and a plant medium layer, which can be live, preserved or dormant moss. In some instances, the system also includes one or more netting layers. The system can also include a watering system, or air circulation system, or both.

An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter comprises a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium comprises a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame comprises a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

An air treatment system includes an air handling unit to direct air into a building structure; a sensor to detect the presence of a target material and produce a signal indicative of the detection of a target material greater than a threshold amount; and a control system to control the air handler based on the signal from the sensor.

An all-in-one, universal bacteria filter apparatus which (i) can be used with oxygen concentrators produced by numerous different manufactures, (ii) can be used with concentrators of different capacities, and (ii) can be use in both vertical and horizontal orientations.

A fluid filtration system is shown. The fluid filtration system utilizes a one-piece or multiple piece containers having a plurality of radiation-transmissible media adapted to receive light, such as ultraviolet light, white light or other wavelength light. The radiation-transmissible media are situated in the container and at least one or a plurality of radiation sources, such as ultraviolet lamps, are situated in an array in proximity to the radiation-transmissible media. The radiation-transmissible media interrupts the flow and velocity of the fluid stream passing through the container to extend the duration of radiation for any contaminants and also provide enlarged surface areas for the contaminants to be received and ultimately exposed to the radiation. In one example, the radiation-transmissible media may be tubular or spherical sections that are hollow or solid and made of quartz.
