Abstract
Abstract An air cleaner assembly for ionizing and filtering air is supported by an electrical receptacle mounted in a wall. A housing supports an enclosed filter and a fan forces air into the housing, wherein the air is filtered and ionized. The filtered and ionized air is forced out of the housing through a grill mounted within the housing. A plug connected to the housing is mateable with the wall mounted electrical receptacle to provide power to the fan and to force air into the housing, through the filter, past the ionizer and out through the outlet grill.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
199 words
An air cleaner assembly for filtering air in a space contained at least in part by a wall, the air cleaner assembly being adapted to be supported by an electrical receptacle mounted in the wall, the air cleaner assembly comprising: a housing having a perimeter wall including inlet grill means for drawing air into the cleaner assembly, and outlet grill means for discharging filtered air from the cleaner assembly; filtering means for filtering air, said filtering means comprising a filter disposed within said housing; fan means for directing air into said housing and through said filtering means when receiving electrical power and for producing filtered air, said filtered air discharged out of said outlet grill means, said filtering means disposed circumferentially about said fan means and adjacent to said inlet grill means so that said fan means draws air into said inlet grill means through said filter means and discharges said filtered air out through said outlet grill means; and a plug, directly attached to said housing that is mateable directly with the wall mounted electrical receptacle to provide power to said fan means for directing air into the housing only when the plug is mated with the receptacle.
Claim 2
Dependent Claim
199 words
An air cleaner assembly for filtering air in a space contained at least in part by a wall, the air cleaner assembly being adapted to be supported by an electrical receptacle mounted in the wall, the air cleaner assembly comprising: a housing having a perimeter wall including inlet grill means for drawing air into the cleaner assembly, and outlet grill means for discharging filtered air from the cleaner assembly; filtering means for filtering air, said filtering means comprising a filter disposed within said housing; fan means for directing air into said housing and through said filtering means when receiving electrical power and for producing filtered air, said filtered air discharged out of said outlet grill means, said filtering means disposed circumferentially about said fan means and adjacent to said inlet grill means so that said fan means draws air into said inlet grill means through said filter means and discharges said filtered air out through said outlet grill means; and a plug, directly attached to said housing that is mateable directly with the wall mounted electrical receptacle to provide power to said fan means for directing air into the housing only when the plug is mated with the receptacle.
Claim 3
Dependent Claim
24 words
The air cleaner assembly of claim 1, further comprising an ionization means disposed within said housing for removing positively charged ions from said air.
Claim 4
Dependent Claim
30 words
The air cleaner assembly of claim 2, further comprising connecting means between said plug and said ionizing means for permitting operation of the fan means independently of said ionizing means.
Claim 5
Dependent Claim
28 words
The air cleaner assembly of claim 2, wherein said ionization means further comprises at least one ionization pin disposed between said filtering means and said outlet grill means.
Claim 6
Dependent Claim
35 words
The air cleaner assembly of claim 1, wherein said housing includes a circular rear housing and a circular front housing coupled to said circular rear housing, said grill means disposed within said circular front housing.
Claim 7
Dependent Claim
23 words
The air cleaner assembly of claim 1, wherein said outlet grill means is rotatable within said housing for directing air into the space.
Claim 8
Dependent Claim
19 words
The air cleaner assembly of claim 1, wherein said filtering means comprises a fluted filter and a charcoal filter.
Claim 9
Dependent Claim
33 words
The air cleaner assembly of claim 1, further comprising switch means mounted on said housing and electrically connected between said plug and said fan means for controlling operation of the air cleaner assembly.
Claim 10
Dependent Claim
172 words
An air cleaner assembly for ionizing and filtering air, the air cleaner assembly comprising: a housing having a front surface and a perimeter wall, said front surface having an outlet grill for expelling ionized filtered air, said perimeter wall having an air inlet grill; filtering means for producing filtering air, said filtering means comprising a filter disposed within said housing and proximate said inlet grill; fan means for directing air into said housing and through said inlet grill and said filtering means when receiving electrical power, said filtering means disposed circumferentially about said fan means and adjacent to said air inlet grill so that said fan means draws air into said air inlet grill through said filter means and discharges said filtered air out through said outlet grill; ionization means disposed between said outlet grill and said filtering means for removing positively charged ions from the filtered air; and a plug, directly attached to said housing, that is mateable directly with a wall mounted electrical receptacle to provide power to said fan.
Claim 11
Dependent Claim
172 words
An air cleaner assembly for ionizing and filtering air, the air cleaner assembly comprising: a housing having a front surface and a perimeter wall, said front surface having an outlet grill for expelling ionized filtered air, said perimeter wall having an air inlet grill; filtering means for producing filtering air, said filtering means comprising a filter disposed within said housing and proximate said inlet grill; fan means for directing air into said housing and through said inlet grill and said filtering means when receiving electrical power, said filtering means disposed circumferentially about said fan means and adjacent to said air inlet grill so that said fan means draws air into said air inlet grill through said filter means and discharges said filtered air out through said outlet grill; ionization means disposed between said outlet grill and said filtering means for removing positively charged ions from the filtered air; and a plug, directly attached to said housing, that is mateable directly with a wall mounted electrical receptacle to provide power to said fan.
Claim 12
Dependent Claim
28 words
The air cleaner assembly of claim 9, wherein said ionization means further comprises at least one ionization pin disposed between said filtering means and said outlet grill means.
Claim 13
Dependent Claim
35 words
