| 20090320426 | Disposable air filter sub-assembly - A disposable air filter sub-assembly that includes: (a) air filtration media; (b) a substantially planar air filter frame providing three-dimensional support for the air filtration media; and (c) an air filter frame-connecting means integrated into the air filter frame. The integrated air filter frame-connecting means are adapted to connect a plurality of identical air filter sub-assemblies into an air filter assembly with sufficient structural strength in at least one direction such that the air filter sub-assemblies resists separation when the air filter assembly is extracted from the filter track of a filter bank. | 12-31-2009 |
| 20130340400 | MAGNETIC ATTACHMENT FOR BOX FAN FILTER - An air filter attachment apparatus for temporarily attaching a furnace-type air filter to a face of a box fan with a ferromagnetic box frame. The attachment apparatus comprises a plurality of magnetic flaps secured to respective top and side edges of the air filter, either directly or via a filter-receiving frame. The filter/frame is sized to approximate the face dimensions of the fan, and the flaps are foldable forwardly toward the fan to lie flat on top and side surface of the fan's metal box frame. Each flap includes magnetic attachment means to secure the flap to the fan. | 12-26-2013 |
