The present invention relates to an individualized air filtration device including a generally inverted U-shaped nose ring and filter combination that fits partially within the nostrils of a user to prevent bacteria, microbes, particulate matter and viruses from entering the body through the user's nasal passages. The nose filtering device is preferably comprised of a nylon mesh material with an acetate fibrous material on at least the backside of the filter so that a hydrogen peroxide or other protective solution can be applied to the device before inserting the filter into the user's nostrils. The solution is preferably comprised of a hydrogen peroxide, but may also include a fragrance, medicine, therapeutic agent, camphor, eucalyptus oil, and a menthol.

Body-worn air-treatment devices include a body that is configured to be selectively coupled proximate to a respiratory tract inlet of a living individual, and a pathogen-deactivating mechanism that is supported by the body. Methods include deactivating pathogens proximate to a respiratory tract inlet of a living individual.

A portable air filtration and disinfection device for a respirator system includes a casing, an inhalation filter assembly, and an exhalation filter assembly. The inhalation filter assembly includes an intake duct for receiving breathing air, an inhalation gas filter for filtering the breathing air, and an inhalation duct to provide the filtered breathing air. The exhalation filter assembly includes an exhalation duct for receiving exhaled air, an exhalation gas filter and an exhalation liquid filter for filtering and disinfecting the exhaled air, and an outlet duct for releasing the filtered and disinfected exhaled air.

Disclosed herein are facial covering that are configured to be placed on facial skin and that may be placed on the skin in a sealed relationship such that air leakage is minimized. The covering may include a member configured to fit flush against skin surrounding at least one of nasal air passages and a mouth of a user, the member including at least one aperture to permit breathing through the nasal air passages, the member being configured to adhere to the skin; and filter material positioned within a space defined by the at least one aperture.

A nostril wearable filtering device for reducing exposure to particulates includes a cylinder, which is tubular and resiliently compressible. The cylinder can be compressed between digits of a hand of a user, positioning the user to insert the cylinder, by a first end thereof, into a nostril. A filter is engaged to the cylinder and extends across a second end of the cylinder. The cylinder is one of a pair of cylinders. Each cylinder of the pair of cylinders can be compressed and inserted into a respective nostril of the user. The cylinders then expand so that the cylinders conform to and sealably engage interior surfaces of the nostrils. The filters filter air passing therethrough, to reduce particulate content of the air, prior to the air entering lungs of the user.
