Abstract
A filter media can include a fiber coated with a barrier coating that is substantially non-reactive to reactive species, and a photocatalytic coating disposed on the barrier coating, wherein the photocatalytic coating generates reactive species in response to illumination with optical radiation.
Claims21
An air purification system comprising:
- a housing defining an inlet and an outlet;
- an impeller operable to urge air along an air flow path between the inlet and the outlet;
- a filter media, arranged within the housing before the impeller, comprising:
- a polymeric fiber coated with an inert coating, wherein the inert coating is inert to reactive oxygen species and hydroxyl radicals;
- a photocatalytic coating disposed on the barrier coating, wherein the photocatalytic coating generates at least one of reactive oxygen species or hydroxyl radicals when illuminated with optical radiation;
- and
- a light source operable to illuminate the photocatalytic coating with the optical radiation.
4 more elements
A filter media comprising:
- a polymeric fiber comprising a glass coating, wherein a thickness of the glass coating is between about 10-200 nm, wherein the glass coating conformally coats the polymeric fiber, wherein the glass coating comprises at least one of borates or silicates, wherein the glass coating is inert to at least one of reactive oxygen species or hydroxyl radicals;
- photocatalytic particles disposed on the glass coating;
- and
- a conductive material in electrical communication with the photocatalytic particle.
