Method and system for the application of materials to improve indoor air quality

An HVAC system for the photocatalytic treatment of airborne organic matter, said system comprising:

• an arrangement of ductwork in which a flow of untreated air is received, said untreated air comprising organic matter;
• a reactor in communication with said ductwork, said reactor comprising particles of anatase titanium dioxide, said particles being electrostatically charged and photocatalytically activatable;
• and
• a collection device in said reactor;
• wherein communication of said particles with said organic matter oxidizes said organic matter, wherein said collection device collects the oxidized organic matter to produce treated air, and wherein said treated air is ejected from said reactor.

A method of treating a surface containing organic matter, said method comprising the steps of:

• providing electrostatically charged particles of anatase titanium dioxide;
• and
• depositing said particles as a coating on said surface containing said organic matter;
• wherein in said step of depositing said particles on said surface, said particles are attracted to said surface and opposed to each other, thereby providing a self-leveling aspect to said coating.

A method of treating a gaseous fluid containing organic matter, said method comprising the steps of:

• providing electrostatically charged particles of anatase titanium dioxide;
• providing an air stream containing organic matter into a chamber;
• causing said electrostatically charged particles of anatase titanium dioxide to come into contact with said organic matter and oxidizing said organic matter;
• separating said oxidized organic matter from said air stream;
• and
• ejecting said air stream from said chamber.
