Abstract
The invention relates to a portable air cleaner unit which includes a casing having an air inlet and an outlet and defining an air cleaning path between the inlet and outlet. A prefilter is disposed downstream of the air inlet and a main filter is disposed downstream of the prefilter. An air mover such as a fan is disposed downstream of the main filter, and an exposed negative ion source is disposed downstream of the fan on the external surface of the air outlet. In accordance with the invention, the main filter consists of fibers shredded from a non-carcinogenic plastic membrane which has been permanently electrostatically charged. The negative ion source ionizes the cleaned air as it leaves the cabinet.
Claims14
An air cleaner unit comprising:
- a casing having an air inlet and an air outlet and defining an air cleaning path between said air inlet and said air outlet;
- filter means disposed across said path between said air inlet and said air outlet and comprising fibers shredded or fibrillated from a non-carcinogenic plastic membrane which has been permanently electrostatically charged;
- air moving means disposed along said path for moving the air from said air inlet to said air outlet;
- an exposed negative ion source disposed on the external surface of said air outlet;
- and
- a power supply connected to the negative ion source, the power supply having means for limiting the current of said power supply to protect users from receiving hazardous electrical shocks from said exposed negative ion source.
An air cleaner unit comprising:
- a casing having an air inlet and an air outlet and defining an air flow path between said air inlet and said air outlet;
- a grill covering the air outlet;
- air moving means disposed along said path for providing an air flow from said air inlet to said air outlet;
- filter means disposed across said path between said air inlet and said air outlet, said filter means comprising a plurality of electrically charged fibers for efficiently cleaning the air flowing from the air inlet to the air outlet;
- and
- a negative ion source located at said grill for producing ions of the cleaned air, said ion source being exposed at the air outlet for providing substantial emission of said ions into the air external to the grill without impediment from charge build-up on the grill.
