Method and systems for filtration of harmful particles are disclosed herein. In one embodiment, a method for making a filtration system for use with a facial covering includes producing a liquid polymerized copper substate, creating a barrier layer by coating a filter media with the liquid copper substrate to coat the filter media with polymerized copper, and binding the barrier layer between two textile layers, wherein each of the two textile layers provides a tortuous path for particles to pass. A filtration system includes a barrier layer including a filter media coated with particulate copper and a polymer.

The invention can be used to produce personal protection systems of respiratory organs (RPE) and organs of vision from airborne and aerosol pathogens. Additionally, it can be used to create mobile low-power closed-type recirculation systems of UV cleaning and air disinfection in small rooms and volumes: salons and cabins of various vehicles, offices, classrooms, medical rooms, etc. According to the claimed characteristics, the invention provides a high level of bactericidal treatment of air flows, including human breathing, by irradiating the flow with UV radiation from UVC-LED source with the formation of multiple times amplified luminous flux in the multi-pass irradiation chamber. The technical result is expressed in a multiple increase in the bactericidal efficacy of the device compared to devices without such a chamber, as well as in the same reduction in the requirements for the radiation power of the primary radiators according to the required bactericidal efficacy of the device.

The invention relates to a powered air-purifying respirator (PAPR) system with a transparent multi-use face shield, a foam frame attached to the interior face of the face shield, a flexible hose secured within a hole bore through the foam frame, a portable air filtering enclosure and a pump contained therein that introduces filtered air into the system through the flexible hose, and a non-woven HEPA cloth carry bag that also functions as an air filter. The face shield features a fastener system that includes flexible straps made from a transparent, flexible, non-stick, and self-adhesive releasable tape. The invention provides the user eye protection and respiratory protection from direct fluid spray, flying debris, unclean air, unhealthy airborne contaminants, including SARS-CoV-2 and other harmful viruses or pathogens.

A Personal Protective Equipment that fits in the Nose of living species, especially human beings, this nose mask is designed for ease of use, comfort to the user, and most of all to filter harmful viruses, bacteria, other filterable microbes, dust particles, and prevent them from entering into their nostrils, thereby protecting the user and preventing them from contracting diseases such as but not limited to COVID-19 (largely known as the novel corona virus during the years 2019 to 2021 pandemic time period), while they are at work, outside, and/or indoors, to ensure that they lead a healthy life. Additionally this Personal Protective Nose Mask can be used for betterment of health by patients, under a Physician's care/treatment who are prescribed inhalable medicines.

Systems and methods for a face shield for attachment to goggles or eyeglasses are disclosed. An attachment portion secures a shield to said googles or eyeglasses. The attachment portion includes an outer band secured to and extending along an upper portion of the shield. An inner band extends along an upper portion of the goggles or eyeglasses. At least one clip removably secures the attachment portion to the goggles or eyeglasses.
