A Personal Protective Equipment (PPE) ensemble made up of a launderable protective hood and an air dispersion protective headgear, is provided. In an exemplary embodiment, the PPE ensemble is made up of a launderable hood that is detachably affixed to and forms a gas-restrictive seal with a protective face shield assembly, an air-supplied protective suit having an air supply inlet/outlet assembly, and an air dispersion protective headgear releasably coupled to the air supply inlet/outlet assembly of the protective suit. The PPE ensemble provides a wearer with a protective hood with reduced or no lens fogging and reduced sound levels under the hood. The PPE ensemble also maintains or cools the skin temperature of the wearer's face during use and thus reduces wearer fatigue.

An oro-nasal interface device includes: a facemask; an intake tube with an inner surface made from a reflective material; an exhaust tube; an intake disinfection unit located at a first end of the intake tube, the intake disinfection unit housing: a battery-powered intake fan in fluid communication with the intake tube that, in operation, creates a positive pressure air flow through the intake tube into the facemask; an intake high-efficiency particulate air filter in fluid communication with the intake tube that filters air passing through the intake tube prior to reaching the facemask; and an intake UV radiation source acting on the air passing through the intake tube prior to reaching the facemask; and an exhaust high-efficiency particulate air filter in fluid communication with the exhaust tube that filters air passing through the exhaust tube after leaving the facemask.

A dog respirator including a mask adapted to surround the dog's head and a positive pressure air supply and filter separate from the mask and adapted to be placed on the dog's body away from the dog's head. The air supply and filter may be attached to the dog's back using a harness. The respirator/mask surrounding the dog's head is connected to and receives positive-pressure filtered air from the filtered air supply so that the interior of the mask is maintained at positive pressure relative to atmospheric pressure with filtered air.

Disclosed is a modular, adjustable, low profile PAPR system allowing customized configuration to meet an operator's weight and space requirements. The system includes a blower, a filter rail chassis that is removably attachable to an inlet of the blower, and a hose system that is removably attachable to the outlet of the blower. The blower unit is adjustable to enable a user or wearer to modify the position of the blower unit outlet, and thus the point of connection of the hose system, in order to allow the user or wearer to route the hose as may be most desirable for their then-current gear configuration, all while maintaining an air-tight airflow conduit extending from the filter rail chassis holding the filter cartridges through the PAPR to the outlet port, and ultimately into the hose system for delivery to the user's mask.

The PAPR Frame is a low cost solution that allows the assembly of a PAPR Device from readily available off-the-shelf elements. To assemble the PAPR Device, a face shield is inserted into the PAPR Frame. To utilize the PAPR Device, a user inserts the visor of a hat into the PAPR Frame and wears the hat. The PAPR Device may further comprise tubing segments; the tubing segments are inserted into tubing apertures arranged through a top curved piece of the PAPR Frame. The PAPR Device may also further comprise one or two sound attenuation structures, which are used to dampen the potential noise generated by the air flow within the PAPR Device.
