ABSTRACT:
A portable enclosure system and method for providing a suitable breathing atmosphere therein includes a chamber. The chamber may assume a variety of shapes. An electric fan and filter assembly is provided and is attached to the chamber by way of a flexible air hose. The fan draws air into the fan and filter assembly and exhausts it into the air hose through a filter. The filtered air travels into the chamber thus providing a positive pressure within the chamber. The positive pressure within the chamber forces unwanted particulates out of the chamber by way of exhaust ports and prevents unwanted particulates from entering the chamber. In providing an enclosure filled with a suitable breathing environment, the chamber is placed on a substantially flat surface. The fan is turned on and the chamber is allowed to be purged of unwanted allergens. The fan remains on to maintain a positive pressure within the chamber and provide a steady supply of fresh filtered air.
