Abstract
The present disclosure is directed to a novel cold climate air exchanger. In one aspect of the disclosure, the cold climate air exchanger is comprised of an interior and an exterior panel that houses an open-celled foam filter insert there between. The assembly cooperates to gain a light weight air exchanger that advantageously regulates the natural moisture and temperature of the inhaled and exhaled air while maintaining adequate airflow for the user.
Claims12
A cold climate air exchanger comprising:
- a front panel of non-porous material having a perimeter and defining an opening generally at a center of the front panel;
- a rear panel of non-porous material having a perimeter and defining an opening generally at a center of the rear panel;
- a porous filter having a density of between 1.75 and 2.25 PCF;
- wherein the front panel and rear panel are joined at their perimeters such that the opening of the front panel is generally aligned with the opening of the rear panel and such that a cavity is defined between the front panel and the rear panel;
- and
- wherein the porous filter is disposed within the cavity and adjacent the generally aligned openings
A cold climate air exchanger comprising:
- a front panel having a cup shape and being comprised of a non-porous fabric, the front panel having a perimeter and defining an opening generally at the apex of the front panel;
- a rear panel having a cup shape and being comprised of a non-porous fabric, the rear panel having a perimeter and defining an opening generally at the apex of the rear panel;
- a porous filter;
- wherein the front panel and rear panel are joined at their perimeters such that the opening of the front panel is generally aligned with the opening of the rear panel, and such that a cavity is defined between the front panel and the rear panel;
- and,
- wherein the porous filter is disposed within the cavity and adjacent the generally aligned openings.
A balaclava containing a cold climate air exchanger comprising:
- a cup shaped portion of non-porous material having a front side and a rear side and defining a volume there between, the cup shaped portion further defining a front side opening located generally at the center of the front side, and a rear side opening located generally at the center of the rear side, said openings being generally aligned;
- a porous filter, having a front surface area, a thickness and a rear surface area, the porous filter being disposed within the volume;
- wherein the filter covers the generally aligned openings;
- and,
- wherein the cup shaped portion is comprised of fabric and is incorporated into a portion of a balaclava.
