Air purification methodology and apparatus

An air purification apparatus, comprising:

• a water tank to hold water;
• a first stage air bubble size reduction module integrated with a bottom of the water tank and designed to reduce air bubble sizes of air entering to the water held in the water tank;
• an electrical blower coupled to the first stage air bubble size reduction module and configured to inject the air into the water tank starting with reduced air bubble sizes;
• and
• a second stage air bubble size reduction module submerged within said water tank to reduce the air bubble sizes of the air;
• and wherein the first stage air bubble size reduction module includes a crushing structure selected from the group consisting of a hollow chamber with a top plate, a spiral pipe structure including a plurality of spiral pipes and a linking pipe array including a plurality of linking pipes;
• wherein said crushing structure comprise a plurality of openings.

A method for air purification, comprising the steps of:

• (a) filling a tank with water through a water inlet;
• (b) driving air, by an electrical air blower, into a first stage air bubble size reduction module integrated at a bottom of said tank;
• (c) injecting the air into the water through a plurality of openings of the first stage air bubble size reduction module, thereby generating small air bubbles injecting into the water to increase water-air contact surface to capture contaminants in the air while being passed through the water tank;
• (d) reducing and crushing the air bubbles sizes further of the air contained in said water tank by a second stage of air bubble size reduction module submerged within said water tank to capture remaining contaminants in the air while being passed through said water tank;
• (e) reducing and crushing the air bubbles sizes of the air contained in said water tank by a third stage of air bubble size reduction module disposed within said water tank located between the second air bubble size reduction module and the first stage air bubble size reduction module to increase water-air contact surface to capture contaminants in the air while being passed through said water tank.
