Abstract

A portable air filter system having a manually operable spray pump for scenting the air flowing therethrough. The system includes an enclosure having an air inlet and an air outlet, a motor/fan assembly for moving air through the air inlet and out the air outlet, a plurality of air filters disposed between the air inlet and the air outlet, and a manually operable pump in fluid communication with a liquid scented material for scenting the air disposed between the air filters and the air outlet. A brush is attached to a pair of side walls of a wide portion of the enclosure and spans the air inlet. In use the brush aids in dislodging dust and lint from fabric materials.

Claims

1. A portable air filter system comprising:

an enclosure having a wide portion a narrow portion, and a tapered portion disposed intermediate the wide portion and the narrow portion, an air inlet being defined by a wide portion beveled periphery and an air outlet being disposed in the narrow portion;

a means for moving air through the air inlet and out the air outlet;

a first random oriented glass fiber filter, a second random oriented glass fiber filter, an active carbon filter, and a cotton fiber filter, the filters being disposed in the wide portion proximate the tapered portion, the filters being insertable into the wide portion through a slot formed in a wide portion top wall; and

a manually operable means for scenting the air disposed between the filtering means and the air outlet.

2. The portable air filter system of claim 1, wherein the wide portion top wall further comprises a recessed portion disposed in partial surrounding relationship to the slot.

3. The portable air filter system of claim 1, wherein the manually operable means for scenting the air between the air inlet and the air outlet further comprise a pump in fluid communication with a liquid scented material disposed in a canister having a nozzle operably coupled to the pump, the canister being disposed in the tapered portion in such manner that the nozzle faces the filters.

4. The portable air filter system of claim 3, wherein the pump has a handle disposed in a slot formed in an enclosure handle.

5. The portable air filter system of claim 1 further comprising a brush attached to a first portion of a brush bracket, the brush bracket having a pair of opposite side members, the side members being attached to opposing wide portion side walls in such manner that the first portion of the brush bracket is disposed in spanning relationship to the air inlet and wherein the brush is disposed distally of the air inlet.

6. The portable air filter system of claim 1, wherein the means for moving air through the air inlet and out the air outlet further comprise a fan operably coupled to an electric motor, the electric motor being disposed in the narrow portion.
