Abstract
A device for facilitating removal of a filter from an air circulation system includes a flexible element having a first, low profile position adjacent a surface of the filter and a second, extended position spaced from the surface of the filter. When in the extended position the flexible element provides a graspable or grippable medium for removing the filter from the air circulation system. The device also includes attaching means for securing the flexible element to the filter.
Claims19
A device for facilitating removal of a filter from an air circulation system, the device comprising:
- a flexible element having a first, low profile position adjacent a surface of the filter and a second, extended position spaced from the surface of the filter, wherein when in the extended position the flexible element provides a graspable or grippable medium for removing the filter from the air circulation system;
- and
- attaching means for securing the flexible element to the filter.
An assembly comprising:
- a filter frame;
- a filter media disposed within and attached to the filter frame for filtering particulate contaminants from an air stream, the filter media having a first major surface and a second major surface for air flow through the filter media from the first major surface to the second major surface;
- and
- a device secured to the filter frame which is urgable substantially flat against the filter frame when the filter is disposed in the air stream and which is extendable from the filter frame to provide a graspable or grippable medium to facilitate removal of the filter from the air stream.
A device for facilitating removal of a filter from an air circulation system, the filter including a filter frame and a filter media disposed within and attached to the filter frame, the device attachable to the filter frame and comprising:
- a flexible element which is positionable substantially flat against the filter frame when the filter is disposed in the air circulation system and which is extendable from the filter frame to provide a grippable medium for pulling the filter from the air circulation system.
