Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 93 words
Ventilation and air quality treatment apparatus for passenger aircraft comprising: a source of pressurized air; a conduit network coupled to said source of pressurized air and to a multiplicity of outlet devices, each of said outlet devices being adapted to be positioned adjacent to an individual passenger location; said multiplicity of outlet devices each constructed so as to define a pressurized air flow pathway therein; and a plurality of individual ionization means each disposed in the air flow pathway of one of said outlet devices for providing ionization of the air passing therethrough.
Claim 2
Dependent Claim 93 words
Ventilation and air quality treatment apparatus for passenger aircraft comprising: a source of pressurized air; a conduit network coupled to said source of pressurized air and to a multiplicity of outlet devices, each of said outlet devices being adapted to be positioned adjacent to an individual passenger location; said multiplicity of outlet devices each constructed so as to define a pressurized air flow pathway therein; and a plurality of individual ionization means each disposed in the air flow pathway of one of said outlet devices for providing ionization of the air passing therethrough.
