Abstract
Air purifier systems for enclosed environments and processes for purifying air within the enclosed environments generally include four stages of filtration. The four stages of filtration include exposing the air to a carbon pre-filter followed by exposing the air to a particulate filter. The air is then fed through a photocatalytic filter and subsequently discharged back into the environment. The systems and processes deodorize, remove particulate matter and destroy airborne pathogens within the enclosed environment.
Claims22
An air purifier system for use in an enclosed environment comprising:
- a housing having an inlet opening and an outlet opening in fluid communication with a housing interior, wherein the housing interior comprises an upper chamber in fluid communication with both the inlet opening and a lower chamber, wherein the lower chamber is in fluid communication with the outlet opening;
- a removable filter disposed at the inlet opening comprising a carbon pre-filter and a particulate filter, wherein the carbon pre-filter comprises a membrane impregnated with activated carbon overlaying the particulate filter;
- an ultraviolet light source and a photocatalytic filter disposed about the ultraviolet light source in the upper chamber, wherein the carbon pre-filter prevents emission of light from the ultraviolet light source from emanating through the inlet opening;
- and
- a fan unit in the lower chamber, wherein the fan unit is configured to horizontally draw environmental air through the removable filter at the inlet opening and into the upper chamber, wherein the air is exposed to ultraviolet radiation from the ultraviolet light source to react with organic contaminants so as to further reduce odor and destroy pathogens, and wherein the air is then directed by the fan unit into the lower chamber and discharged through the outlet opening for return to the environment free of odor and organic contaminants.
An air purifier system for use in an enclosed environment comprising:
- a housing having an inlet opening and an outlet opening in fluid communication with a housing interior;
- a removable filter disposed at the inlet opening comprising a carbon pre-filter and a particulate filter, wherein the carbon pre-filter comprises a membrane impregnated with activated carbon overlaying the particulate filter;
- an ultraviolet light source configured to produce UVC radiation and a cylindrical shaped photocatalytic filter disposed about the ultraviolet light source, wherein the carbon filter prevents emission of the UVC radiation from the enclosed environment;
- and
- a fan unit, wherein the fan unit is configured to horizontally draw environmental air through the removable filter at the inlet opening, through the photocatalytic filter, and discharged through the outlet opening for return to the environment free of odor and organic contaminants.
A process for purifying air within an enclosed environment, the process comprising, in sequence:
- drawing air into a removable filter provided at an inlet opening of an air purifier system to reduce odors and particulate matter within the air, wherein the removable filter comprises a carbon pre-filter including a membrane impregnated with activated carbon and a particulate filter;
- flowing the reduced odor and particulate matter air through a photocatalytic filter, wherein the photocatalytic filter comprises an ultraviolet light source and a cylindrical filter impregnated with a photocatalytic material about the ultraviolet light source to form a purified air flow free of odor and particulate matter, wherein the carbon pre-filter overlies the particulate filter and substantially prevents emission of the ultraviolet light from the air purification system;
- and
- discharging the purified air flow from an outlet opening into the enclosed environment.
