Duct end filter apparatus
View Patent ↗The present invention is an improved duct end filtering device which increases the efficiency of a duct-end filter and which increases the ease with which filters can be removed and replaced.
1. A filtered air vent apparatus comprising:
a vent housing body comprising at least four sides forming an air passageway between at least a first open end and a second open end, the vent housing body further comprising at least two filter supports extending toward the first open end of the housing body;
a grill hingedly attachable to the vent housing body and securable to the vent housing body in a snap fit configuration;
a bezel attached to the grill; and
a filter slidably positionable between the grill and the bezel;
wherein the at least two filter supports of the vent housing body engage the filter at a location spaced from a perimeter of the filter and hold the filter against the grill when the grill is secured over the first opening of the housing and the at least two filter supports of the vent housing body disengage the filter when the grill is hingedly opened, allowing the filter to be slidably removed from the grill and attached bezel.
2. The vent of claim 1 , wherein the at east two filter supports of the vent housing body are formed integral to a support arm extending from at least one side of the housing body.
3. The vent of claim 1 , wherein the vent is an air return vent.
4. The vent of claim 1 , wherein the vent is a heating or air conditioning vent.
5. A filtered air vent apparatus comprising:
a monolithic, plastic vent housing body comprising at least four sides forming an air passageway between at least a first open end and a second open end, the monolithic, plastic vent housing body further comprising at least two filter supports extending from at least one of the at least four sides of the housing body toward the first open end of the housing body;
a monolithic, plastic grill hingedly attachable to the vent housing body and securable to the vent housing body in a snap fit configuration;
a plastic bezel attached to the grill;
a filter slidably positionable between the grill and the bezel;
wherein the at least two filter supports of the vent housing body engage the filter at a location spaced from a perimeter of the filter and hold the filter against the grill when the grill is secured over the first opening of the housing and wherein the at least two filter supports of the vent housing body disengage the filter when the grill is hingedly opened, allowing the filter to be slidably removed from the grill and attached bezel.
6. The vent of claim 5 , wherein the at east two filter supports of the vent housing body are formed integral to a support arm extending from at least one side of the housing body.
7. The vent of claim 5 , wherein the vent is an air return vent.
8. The vent of claim 5 , wherein the vent is a heating or air conditioning vent.
