Multi Stage Disinfecting Air Cleaner

A method of purifying air from a room comprising:

• drawing the air from a room through a corona discharge region;
• drawing the air through a linear electric field region;
• passing the air through a porous barrier filter;
• drawing the air through an ultra-violet (UV) light beam;
• expelling the air back into the room.

An air purification system comprising:

• (a) an electrostatic barrier filter (EBF) comprising:
• (i) a high voltage corona discharge chamber having a discharge electrode and collector electrode fluidly coupled to an air inlet port;
• (ii) a high voltage linear electric field chamber fluidly coupled to the corona discharge chamber, the linear electric field chamber containing a porous barrier filter element having a hollow interior constructed to allow air to flow from the linear electric field chamber through the porous barrier filter element and into the hollow interior;
• (b) a germicidal section comprising:
• an ultra-violet (UV) light chamber fluidly coupled to the hollow interior of the porous filter element, the UV light chamber including at least one UV light source;
• (c) an activated carbon section comprising:
• an activated charcoal filter constructed to pass air from the UV light chamber to an exit port through an exhaust fan.
• wherein, the fan draws ambient air from a room through the electrostatic barrier filter, through the germicidal section, and, through the activated carbon section, returning purified air to the room.
