An attractive portable air cleaner effectively purifies air in a room or office for added comfort and a healthier environment. Instead of using expensive custom-made filters, the air cleaner uses regular toilet paper or paper towels for customer convenience and lower customer costs. A quiet blower system circulates air through the air cleaner. Ion emitters are positioned near the intake and collector plates support and charge the paper media.

[ What is claimed is:] [1.] An air cleaner, comprising:a housing providing a casing with an upper housing portion and a lower housing portion, said upper portion having a substantially circular top providing a cover and a skirt comprising an annular wall extending integrally downwardly from said top, said top having a series of radial ribs and defining a substantially circular set of radial inlet passageways between said ribs providing an air intake for entrance of influent air laden with particulates of dust, pollen, smoke, soot or other pollutants, said lower housing portion providing a base positioned below and supporting said upper housing portion, said base having at least one ion generator compartment and a blower compartment positioned in proximity to said ion generator compartment, said base having an upper lid defining a blower opening communicating with said blower compartment and said upper housing compartment, said base having sidewalls extending integrally downwardly from said lid and a duct defining an outlet opening providing an air exhaust in proximity to said blower compartment;an ionizer assembly comprising a circular array of negatively charged ion emitters comprising ion-emitting pins or needles for emitting ions to ionize said influent air and negatively charge said particulates;said ion emitters being disposed in proximity to said intake, an upright tubular superstructure comprising an electrically insulating rigid plastic annular shell providing an ion emitter-support stand, said shell having an upper emitter-support portion for supporting said ion emitters, said ion emitters being circumferentially and aliquotly spaced from each other and extending radially outwardly from said upper emitter-support portion, said shell having a substantially horizontal annular coil-support portion extending below said upper emitter-support portion, an electrical coil positioned about said coil-support portion and connected to said ion emitters, said shell having an upright elongated support portion extending downwardly below said coil-support portion, said upright support portion defining at least one upright paper-dispensing slot and having a bottom section and said upright support portion having an outer collector plate-engaging surface and an inner paper roll-facing surface;a collector assembly comprising an upright roll of disposable paper for collecting said negatively charged particulates, said roll of paper being peripherally and annularly surrounded by said shell and being disposed inwardly of said shell, positively charged curved collector plates positioned against said outer collector plate-engaging surface of said shell, said collector plates comprising diametrically opposed imperforate fluid-impervious metal collector plates, each of collector plates being arcuate with convex exterior paper-supporting surface facing said housing and a concave interior surface abutting against and securely engaging said collector plate-engaging surface of said shell, said collector plates being circumferentially spaced from each other to provide a dispenser defining an upright dispensing opening aligned in registration with said upright paper-dispensing slot of said shell for dispensing and passing paper from said roll onto said exterior paper-supporting surface of said collector plates, said dispensed paper including a paper portion detachably covering a substantial portion of said exterior paper-supporting surface of said collector plates and said paper portion being positively charged by said collector plates for attracting and collecting said negatively charged particulates;a paper roll-support stand comprising a substantially circular raised support platform and an upwardly extending spindle with a rounded apex for supporting said roll of paper, said paper roll-support stand having an annular flange providing a rim extending radially outwardly of and at an elevation slightly below said raised support platform, a substantially circular annular shoulder positioned about and extending downwardly from an upper edge of said raised support platform, said shoulder connecting said raised support platform, said shoulder connecting said rim to said raised support platform, said rim abuttingly engaging and supporting said bottom section of said ion emitter-support stand at a position adjacent said shoulder, said rim defining a set of air holes positioned radially outwardly of said emitter-support stand and said collector plates for communicating with said blower opening, said paper roll-support stand having an annular leg portion extending integrally downwardly from said rim at a location radially outwardly of said holes for seating upon said lid of said base, and an annular support wall extending upwardly from said leg portion;said collector plates being spaced from and cooperating with said housing to define an annular air passageway positioned between and communicating with said intake and said air holes of said rim;a negative ion generator and a positive ion generator disposed in said ion generator compartment, said negative ion generator comprising a negative power supply connected to said ion emitters, and said positive ion generator comprising a positive power supply connected to said collector plates;an air blower assembly positioned in the blower compartment for drawing air through said intake into said annular air passageway past said ion emitters and said positively charged paper portion on said collector plates and through said air holes into said blower opening and for blowing cleaner air having a substantially lower concentration of particulates than said influent air through said exhaust, said blower assembly comprising an induction motor having a stator, a rotor positioned within said stator, an upright shaft rotatably disposed within and extending substantially vertically through at least part of said rotor and stator, and a blower wheel comprising a fan extending below and connected to said shaft and communicating with said blower opening and said exhaust for blowing cleaner air through said exhaust out of said air cleaner.
