    Abstract: An indoor air purification apparatus and method includes a watertight chamber including a top portion having a water inlet, a first air portal, a second air portal, a bottom portion, and a plurality of shelves mounted between the top portion and the bottom portion. Water continuously flows from the water inlet at the top of the chamber, typically falling over the shelves to a reservoir. Typically, a water pump returns the water to the water inlet at the top portion of the chamber through at least one conduit leading from the reservoir. An air pump typically drives the room air through the chamber from one air portal to the other and back into the room. The room air is purified as it mixes with the water cascading over the shelves.
