Abstract
Air filters are disclosed. The air filters include filtration media comprising a first surface (104) comprising a first region (106) proximate a first end (110) of the filtration media and a second region (108) proximate a second end (112) of the filtration media. The second region (108) is configured to provide a zone including either a densified zone of the filtration media or a support layer (114) adjacent to the filtration media. Also an air conditioning unit with the air filters is disclosed. And also a method of manufacturing the air filters is disclosed.
Claims25
An air filter, comprising:
- filtration media comprising a first surface comprising a first region proximate a first end of the media and a second region proximate a second end of the media;
- an adhesive on at least a portion of the second region of the filtration media;
- and
- wherein at least a portion of the second region of the filtration media further comprises at least one of:
- a support layer positioned adjacent to the first surface of the filtration media;
- and/or
- a densified region in which fibers in the filtration media that are proximate the first surface in the second region are more densely configured than the fibers proximate the first surface in the first region.
