Vehicle air purification system with photocatalysis filtration

An air purification system comprising:

• an outer shell;
• an inlet housing coupled to a first end of the outer shell;
• and
• an outlet housing coupled to a second end of the outer shell;
• wherein air is received through the inlet housing and expelled through outlet housing;
• wherein the outer shell configured to enclose an air circulation unit and an air purification assembly disposed adjacent the air circulation unit, the air purification assembly comprising:
• a first UV light source and a second UV light source;
• and
• a photocatalytic filter configured to activate responsive to light produced by each of the first UV light source and the second UV light source;
• wherein the first UV light source and the second UV light source are disposed on a same side of the photocatalytic filter configured to illuminate the photocatalytic filter and are positioned respectively at a first angle and a second angle relative to the same side of photocatalytic filter;
• and
• wherein the air purification assembly is configured to purify the air circulated by the air circulation unit.

A method of purifying ambient air in a confined space by an air purification system, the method comprising:

• illuminating, by a first UV light source and a second UV light source, a photocatalytic filter disposed within a filter housing, wherein the first UV light source and the second UV light source are disposed on a same side of the photocatalytic filter, and wherein the first UV light source and the second UV light source are oriented at a respective first angle and a second angle relative to the same side of the photocatalytic filter;
• and
• circulating, by an air circulation unit disposed adjacent the photocatalytic filter, air through the photocatalytic filter;
• wherein the photocatalytic filter activates responsive to illumination by the first UV light source and the second UV light source, and wherein the photocatalytic filter is configured to neutralize volatile organic compounds (VOCs) within the air when activated;
• wherein air circulation unit is configured to draw the air through an inlet housing and expel the air through an outlet housing, and wherein the inlet housing and the outlet housing are respectively coupled to a first end and a second end of an outer shell;
• wherein the outer shell is configured to contain the first UV light source, the second UV light source, and the filter housing, and the air circulation unit;
• and
• wherein the first UV light source is a light emitting diode tuned to a UV-A wavelength and the second UV light source is a light emitting diode tuned to a UV-C wavelength.
