Abstract
A low pressure tank and filler mechanism for holding clean air for dispensing in the vicinity of a user. The tank can contain a plurality of balloon-like structures, each holding a certain quantity of low pressure air. The balloons are coupled to a central hollow column or manifold whereby pure air is either loaded or discharged from the balloons. The tank mates by an external valve into a filler machanism that conveniently fills the tank with air that has been purified by passing it through a series of different types of filters.
