A personal air filter device with an air filter assembly retained in the air filter holding member is disclosed. An ear support member is attached to the air filter holding member and can be hung over the ear of the user to support the air filter holding member. Alternatively, a clip member attached to the air filter holding member can be utilized to attach the device to the user's clothing or accessories. An air tube assembly extends from the air filter holding member to the mouthpiece for the purpose of breathing filtered air flowing through the air filter assembly. An air intake check valve situated near the end of the air tube attached to a mouthpiece retaining member and an air outflow check valve situated near the outer surface of the mouthpiece retaining member to ensure exhaled air is directed out of the device and is not reinhaled.

The present invention is a portable air purifier device intended to be attached to the belt or to the neck of the user and generate purified air enough to breath easily and adequate to make an air curtain to push a way ambient air. Principle of the operation of this device is to push inlet polluted air through layers of ionized water. Water will absorb particles and copper and silver ion kills possible air born bacteria and produce clean air. The purified air will be then delivered to the face of the user either by a flexible hose to a mask or through several flexible hoses to form an air curtain in front of a user's face.

One or more battery-operated fans are integrated into a hard hat and pull air through a filter to remove contaminants in the air. The filtered air passes through one or more channels in the hard hat and exits the hard hat through an air curtain exit located near the user's face. The exiting air leaves with sufficient velocity to form an air curtain. A user wearing goggles or other protective eyewear will have the filtered air current pass in front of the eyewear. Paint and other contaminant particles that are in the air will not be able to contact the outer surface of the eyewear, as the particles will not be able to pass through the curtain of filtered air.

A personal protection system including a support (100) worn around the head and a hood (400) worn over the head and the support. A ventilation unit (150) attached to the support draws air into the hood. Ultraviolet lights (360) direct light into the air stream drawn into the hood. The light renders microorganisms in the air stream innocuous.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. Integral with the helmet is a ventilation fan. The helmet also includes a light assembly for illuminating the surgical field. The helmet includes a front nozzle from which air from the ventilation fan is discharged. The light assembly is mounted to the helmet and is located below the front nozzle. Air discharged from the front nozzle blows heat generated by the light assembly away from the light assembly. In some versions of the invention, the light assembly includes a control arm connected to the light assembly for pivoting the light assembly.
