Portable air cleaning apparatus
First Claim
1. A portable air cleaning apparatus, comprising:
- a body casing a bottom wall, at least one sidewall extending from and about the bottom wall, and a removable top wall extending over the sidewall, the body casing defining a hollow interior having an upper portion defining a fluid spray chamber and a lower portion defining a liquid reservoir;
at least one air inlet extending through the body casing for admitting ambient air into the hollow interior;
a plurality of air outlets extending through the body casing for exhausting purified air from the hollow interior;
means for drawing ambient air through the air inlet into the fluid spray chamber and for discharging cleansed air through the air outlets;
at least one spray nozzle disposed inside the fluid spray chamber adapted for spraying a liquid fluid into the fluid spray chamber as a plurality of fine droplets;
at least one replaceable inlet filter located below the air inlet for creating a counter-current contact between the liquid fluid and the air and for removing a portion of air-borne impurities retained in the liquid fluid; and
at least one replaceable outlet filter disposed immediately before the air outlets for removing impurities and particulate matter from the cleansed air.

Abstract
The portable air cleaning apparatus includes a body casing that has a base having a generally vertical sidewall and removable top wall. A fluid spray chamber has a recirculation system that supplies a fluid to at least one spray nozzle through which the fluid is sprayed into the fluid spray chamber. An air driving mechanism directs ambient air into an air inlet through the fluid spray chamber and discharges at least partially purified air out a plurality of air outlets. At least one inlet filter is positioned between the air inlet and a reservoir inside the spray chamber to create a counter-current contact between the air and the fluid to maximize the removal of particulates from the air. At least one outlet filter is positioned below the air outlets to further remove particulate matter from the air flow being discharged through the air outlets.

12. A portable air cleaning apparatus, comprising:
-
a tank defining a fluid spray chamber;
a removable top wall attached to the tank for gaining access therein;
an air inlet attached to the removable top wall for admitting ambient air into the tank;
a plurality of air outlets attached to and extending away from the removable top wall for exhausting purified air from the tank;
