Abstract
Abstract A convertible air cleaner comprising an elongated enclosure forming an internal cavity. A first opening is at one end of the enclosure and a second opening is at an opposed end of the enclosure and with the openings oriented substantially at 180° from each other. A support structure holds the elongated enclosure at a substantially center axis between said first and second openings. A pivot permits rotation about said center axis between said first and second openings through an arc of at least 180°. An air filter is contained within the enclosure and a fan is positioned within the enclosure for drawing air through said first opening through the internal cavity for filtration by the air filter for exiting to the exterior of the enclosure through the second opening.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
215 words
A convertible air cleaner comprising: an elongated enclosure forming an internal cavity extending along a central longitudinal axis and having a first opening at one end of the enclosure and a second opening at an opposed end of the enclosure and with the openings oriented substantially at 180° from each other and wherein said elongated enclosure includes opposing elongated wall members extending along and parallel to the central longitudinal axis and with the first and second openings each located at an end portion of a wall member at opposite ends of the enclosure to have the openings symmetrically oriented 180° from each other but facing along parallel planes relative to the longitudinal axis; support means holding said elongated enclosure at a substantially transverse axis relative to the longitudinal axis between said first and second openings and including pivot means for permitting rotation about said transverse axis between said first and second openings through an arc of at least 180° for converting the relative position of the first and second openings; air filtration means contained within said enclosure; and fan means positioned within the enclosure for drawing air through said first opening through the internal cavity for filtration by said air filtration means and for exiting to the exterior of said enclosure through said second opening.
Claim 2
Dependent Claim
