Abstract
Disclosed is an air filter and a method of manufacture for an air filter which is much more cost effective and provides greater operational effectiveness than state-of-the-art air filters. The air filter includes an outer metallic shell which may be used to attach the filter in line to ducting of a heating, ventilation, and air conditioning (HVAC) system. The filter may further include a filter unit made of activated carbon material. The filter unit may have one or more sections and may have a honeycomb cross section.
Claims12
An air filter for filtering contaminants from a heating, ventilation, and cooling system, comprising:
- a shell including one or more beads for strengthening the shell, the shell forming a solid exterior wall defining an interior;
- one or more a-rings located in the one or more beads;
- and
- a honeycomb carbon filter unit made of an activated carbon material and located in the interior of the shell, the honeycomb carbon filter unit being adjacent to the one or more a-rings, the honeycomb carbon filter unit having a wall defining an exterior surface and an interior, and the honeycomb carbon filter unit further including a honeycomb structure cross section in the interior.
A method for manufacturing an air filter, comprising:
- forming a honeycomb carbon filter unit from activated carbon, the honeycomb carbon filter unit including an exterior surface, a honeycomb cross section including a plurality of channels extending an entire length of the honeycomb carbon filter unit, a honeycomb carbon filter unit first end and a honeycomb carbon filter unit second end;
- strengthening the exterior surface with a compound or structure;
- and
- attaching a shell including one or more beads or cross bends to the exterior surface;
- wherein the honeycomb carbon filter unit includes a first structure on the first end and a second structure the second end which causes air passing through the filter unit to move in a pre-determined pattern.
