Abstract
An air filtration media for use with a heating ventilation and air condition (HVAC) system is provided. The filtration media comprises an air filter media layer having a first and second side, a PCO media layer having a first and second side, and a barrier layer positioned between the second side of the air filter media layer and the first side of the PCO media layer. The air filter media layer, barrier layer, and PCO layer are pleated together and enclosed within a frame for placement adjacent a light source within a plenum of the HVAC system.
Claims20
An air filtration media for use with a heating ventilation and air condition (HVAC) system, the filtration media comprising:
- an air filter media layer having a first and second side;
- a photocatalytic oxidation (PCO) media layer having a first and second side;
- and
- a barrier layer positioned between the second side of the air filter media layer and the first side of the PCO media layer;
- wherein the air filter media layer, barrier layer, and PCO layer are pleated together and enclosed within a frame for placement adjacent a light source within a plenum of the HVAC system.
A method of manufacturing an air purification system for use in a plenum comprising a heating, ventilation and air condition (HVAC) system, the method comprising:
- providing an air filter media having a first side and a second side;
- providing a photocatalytic oxidation (PCO) media having a first side and a second side;
- positioning a protective barrier between the second side of the air filter media and the first side of the PCO media;
- pleating the air filter media, barrier, and PCO media into at least one pleating pattern having multiple pleats and enclosing the at least one pleating pattern within a frame;
- positioning a light source adjacent the frame proximal to the second side of the PCO media;
- wherein the frame and light source are positionable within the plenum of the HVAC system.
A heating, ventilating and air conditioning (HVAC) air purification system, comprising:
- a filtration media, the filtration media enclosed within a frame, comprising:
- an air filter layer having a first and second side;
- a photocatalytic oxidation (PCO) layer having a first and second side;
- and
- a barrier layer between the second side of the air filter layer and the first side of the PCO layer;
- and
- a light source adjacent to the filtration media proximal to the second side of the PCO layer;
- wherein the filtration media and light source are situated within a plenum.
