Odor absorbing container with an absorbent material between inner and outer concentric walls

A purifying device comprising:

• an outer wall having a generally cylindrical shape with open first and second ends, and having a plurality of open slots extending in a circumferential direction around said outer wall and space apart along a longitudinal direction of said outer wall, said slots being of sufficient size to allow air or water to pass through said outer wall;
• an inner wall concentric with and spaced inwardly from said outer wall and defining an axial passage, said inner wall having a generally cylindrical shape with a first open end and a second open end, and having a plurality of spaced apart open slots extending in a circumferential direction around said inner wall, said slots being of sufficient size to allow air or water to pass through said inner wall, said inner wall being spaced from said outer wall a distance to define an annual space therebetween;
• a first end cap having an end plate coupled to and closing said first end of said outer wall and having a center opening in said end plate adjacent said first open end of said inner wall;
• a second end cap having an end plate and closing said annular space at said second end of said outer wall;
• a particulate adsorbent material contained in said annular space and having a particle size greater than a width of said slots in said outer and inner walls;
• and
• a flexible tube concentric with said inner wall and being positioned in and contacting an inner surface of said inner wall, said flexible tube having a plurality of fluid outlet openings adjacent said inner surface of said inner wall, and a pump for supplying a source of air or water through said annular space from said slots in said inner wall outwardly through said slots in said outer wall.

An air purifying device for removing contaminants from the air, comprising

• a housing having a top wall, a bottom wall, a rear wall, first and second end walls, and first and second supports adjacent said end walls;
• and
• a contaminant adsorbing container supported at first and second ends by said first and second supports, said supports spacing said contaminant adsorbing container from said top, bottom and rear walls a distance to allow air circulation around said container, wherein said container comprises
• an outer wall having a generally cylindrical shape with open first and second ends, and having a plurality of spaced apart open slots extending in a circumferential direction around said outer wall, said slots being of sufficient size to allow air or water to pass through said outer wall;
• an inner wall concentric with and spaced inwardly from said outer wall and defining an axial passage, said inner wall having a generally cylindrical shape with a first open end and a second open end, and having a plurality of spaced apart open slots extending in a circumferential direction around said inner wall, said slots being of sufficient size to allow air or water to pass through said inner wall, said inner wall being spaced from said outer wall a distance to define an annual space therebetween;
• a first end cap having an end plate coupled to and closing said first end of said outer wall and having a center opening in said end place adjacent said first open end of said inner wall;
• a second end cap having an end plate and closing said annular space at first end of said outer wall, and having a center opening in said end plate adjacent said second of said inner wall;
• a particulate adsorbent material contained in said annular space and having a particle size greater than a width of said slots in said outer and inner walls;
• and
• an air permeable front wall removably coupled to said housing.

An air purifying device comprising
