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.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A portable enclosure system for a person with a respiratory ailment, the system comprising:a soft-walled structure defining an enclosure;a means for supporting the structure;a fan means to provide air;a first means for receiving air supplied to the enclosure from the fan means;a filter means for removing particulates from air provided by the fan means before the air is supplied to the first means for receiving air;a means for exhausting air from the enclosure that ensures a positive pressure is maintained within the enclosure, the means for exhausting air also being adapted for receiving air into the enclosure in the event the fan means fails and the pressure within the enclosure approaches ambient levels; andthe first means for receiving air within the enclosure being located within an upper region of the enclosure, laterally disposed and above from the means for exhausting the air, whereby when air is provided to the first means for receiving air from the fan means and the filter means, a gradient of filtered air is established from an upper region to a lower region within the enclosure, ensuring the removal of particulates from within the enclosure through the exhaust means.
