Cartridge for mounting lithium hydroxide sheets
First Claim
1. A cartridge mounting an air treatment material comprising:
- a housing;
air treatment material received within said housing, said air treatment material being designed to remove carbon dioxide from breathing air, and spaced from inner walls of said housing by a plurality of resilient sheets, said resilient sheets being positioned within said housing;
there being an inlet direction into said housing for air flowing across said air treatment material and an outlet opening on an opposed side of said housing, and with there being top and bottom surfaces and side surfaces forming a perimeter about said air treatment material, and said resilient sheets extending substantially continuously across said side surfaces and said top and bottom surfaces at least at an inlet end to increase airflow across said air treatment material;
the resilient sheets are foam;
said foam sheets at said top and bottom surfaces include a plurality of foam sheets;
said plurality of foam sheets at said top and bottom surfaces have different spring forces;
a first of said plurality of said foam sheets at said top and bottom surfaces, which is positioned adjacent said air treatment material, has a lower spring force than a second of said plurality of foam sheets at said top and bottom surfaces which is positioned on an opposed side of said first relative to said air treatment material;
said first and second of said plurality of foam sheets at said top and bottom surfaces extend along crossing legs crossing between said sides, and side surfaces with a central cutout; and
said air treatment material is lithium hydroxide.

Abstract
A cartridge mounting an air treatment material is a housing defining a housing in a perimeter. The air treatment material is received within the housing, and spaced from the inner wall of the housing by a plurality of resilient sheets. There is an inlet direction into the housing for air flowing across the air treatment material and an outlet opening on an opposed side of the housing. There are top and bottom surfaces and side surfaces forming a perimeter about the air treatment material. The resilient sheets extend substantially continuously across the side surfaces and the top and bottom surfaces at least at the inlet end to increase airflow across the air treatment material. An enclosed inhabited space is also disclosed and claimed.

5. An enclosed inhabited space comprising:
-
an enclosure to be inhabited by a living entity, and containing air, and a system for delivering said air across a cartridge containing air treatment material; a housing; air treatment material received within said housing, said air treatment material being designed to remove carbon dioxide from breathing air, and spaced from inner walls of said housing by a plurality of resilient sheets, said resilient sheets being positioned within said housing; there being an inlet direction into said housing for air flowing across said air treatment material and an outlet opening on an opposed side of said housing, and with there being top and bottom surfaces and side surfaces forming a perimeter about said air treatment material, and said resilient sheets extending substantially continuously across said side surfaces and said top and bottom surfaces at least at an inlet end to increase airflow across said air treatment material; said resilient sheets have cutout portions to result in lower spring force at positions spaced from said inlet end; and said air treatment material is lithium hydroxide. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
