Abstract
A system for indoor pollution control that purifies ambient air in a room. The air-purification components can be housed, for example, in an item of ordinary furniture such as a chair. This allows large components capable of high purification rates to be used, but without the large space requirements hitherto normally required with previously known high-rate systems. In addition, the air flow is directed so that a localized spatial zone can be preferentially purified without the need for physical enclosures. The system can be used to prevent dispersion of harmful substances such as pathogens or tobacco smoke that originate from a source, and can also create a microenvironment of purified air.
Claims7
An air-purification system for preventing pollutants generated at a localized region of space from being dispersed from said localized region into the surrounding regions of said space, said system comprising:
- a structure being positioned in said localized region and having a base which includes a housing;
- said base having inlet means for admitting air containing pollutants generated at said localized region into said housing;
- air purification means contained within said housing and comprising one or more filters and a blower means for circulating said air containing pollutants through said one or more filters;
- said base having outlet means for distributing the air flowing from said one or more filters into two or more separate filtered air streams and;
- means for causing said filtered air streams to be directed so as to provide controlled amounts of air flowing in each of said two or more separate filtered air streams for drawing pollutants in the air from said localized region toward said inlet means.
