Abstract
Air purification devices are disclosed that cleanse air of germs and microbes through an oxidation process using an ultraviolet light source that causes a chemical reaction with a proximate catalyst-coated surface. The devices use a replaceable ionization cell folded into a core assembly and positioned around the ultraviolet light source. The ionization cell is coated with the reactive catalyst on at least an inner surface facing the light source and air is cleansed as it passes through the ionization cell. The devices provide safety mechanisms to protect against human exposure to the ultraviolet light.
Claims5
An air purification unit comprising:
- an ultraviolet light source;
- an ionization cell having an inner surface coated with a catalyst, the inner surface forming a series of ridges and troughs wherein each trough has at least one foldable seam that allows the ionization cell to fold at least partially around the ultraviolet light source, the ionization cell further comprising a first edge and a second edge, and wherein, in an unfolded position of the ionization cell, the first edge is facing away from the second edge, while, in a folded position of the ionization cell, the first edge is facing toward the second edge;
- a rigid sleeve, wherein the ionization cell may be slid into the rigid sleeve only when the ionization cell is in the folded position, the rigid sleeve having an inner surface that forms a rib, and wherein the first edge and the second edge fit up against the rib when the ionization cell is slid into the rigid sleeve;
- and
- a fan assembly positioned to create an airflow along at least the inner surface of the ionization cell.
