A reusable respirator including a mask adapted for covering and conforming to the face around the nose and a mouth of a user, a strap configured to secure the mask to a face of the user, and a filter component. All components of the respirator are capable of being cleaned, disinfected and sterilized at temperatures in excess of 50&#xb0; C. An outer surface of the mask is substantially smooth and wettable for easily disinfecting and is shaped with a pair of outer shield portions for housing particulate air filters. The outer shield portions each include a closeable vent through the outer surface that is adapted to provide a user seal check and direct air flow through the outer surface for filtering by the respective particulate air filter, which is adapted to filter at least 95% of airborne particles.

Reusable respiratory protection device

A filter assembly for use with a respirator may include a conformal filter having a body with at least one filter bed, an input end, and an output end recessed within the body and having an integral threaded connector having external threads adapted to thread onto a respirator inhalation connector, and a threaded connector piece removably mounted to the integral threaded connector of the conformal filter.

Filter asssembly for a respirator

Disclosed is multi-flow filter cartridge assembly that includes an elongated housing that has axially opposed proximal and distal ends and defines an interior cavity and first, second and third flow paths which extend from the proximal end of the housing to the distal end. The cartridge assembly also includes first, second and third filter elements. The first filter element is disposed within the interior cavity of the housing and conditions fluid that traverses the first flow path from a first inlet port to a first outlet port. The second filter element is disposed within the interior cavity of the housing and conditions fluid that traverses the second flow path from a second inlet port to a second outlet port. Lastly, the third filter element is also disposed within the interior cavity of the housing and conditions fluid that traverses the third flow path from a third inlet port to a third outlet port. The first flow path is isolated from the second and third flow paths and the second flow path is isolated from the third flow path.

Multi-flow filtration system

A filter cartridge assembly including a replendam that combines a particulate filter with an irregular shaped gas sorbent bed. Best operational practice requires that the air passing through the filter be distributed uniformly over the sorbent bed. The repledam directs the air over the surface of the larger sorbent bed utilizing vane-like structures extending from the reticulated member providing for uniform distribution.
