Abstract
A gas filter element comprising: a first end and a second end, having a plurality of inlet channels and a plurality of outlet channels between the first end and the second end, wherein, in an alternating pattern, the plurality of inlet channels each have an inlet channel opening at the first end, and are closed at the second end, and the plurality of outlet channels each have an outlet channel closed at the first end, and an opening at the second end; each of the plurality of inlet channels being surrounded by outlet channels, each inlet channel surrounded by outlet channels forming an individual channel unit; the plurality of inlet channels and the plurality of outlet channels in each individual channel unit having common porous walls.

A gas filter element comprising:
- a first end and a second end, having a plurality of inlet channels and a plurality of outlet channels between the first end and the second end,
- wherein, in an alternating pattern, the plurality of inlet channels each have an inlet channel opening at the first end, and are closed at the second end, and the plurality of outlet channels each have an outlet channel closed at the first end, and an opening at the second end, each outlet channel forming a gap between adjacent inlet channels, the gap extending to the second end;
- each of the plurality of inlet channels being surrounded by outlet channels, each inlet channel surrounded by outlet channels forming an individual channel unit, each individual channel unit surrounded by the gap extending to the second end, such that adjacent individual channel units do not contact one another;
- the plurality of inlet channels and the plurality of outlet channels in each individual channel unit having common porous walls.
A gas filter element comprising:
- a first end and a second end, having a plurality of inlet channels and a plurality of outlet channels between the first end and the second end,
- wherein, in an alternating pattern, the plurality of inlet channels each have an inlet channel opening at the first end, and are closed at the second end, and the plurality of outlet channels each have an outlet channel closed at the first end, and an opening at the second end, each outlet channel forming a gap between adjacent inlet channels along a partial length between the first end and the second end;
- each of the plurality of inlet channels being surrounded by outlet channels, each inlet channel surrounded by outlet channels forming an individual channel unit, each individual channel unit surrounded by the gap along the partial length between the first end and the second end, wherein adjacent individual channel units are held together by a support bracket;
- the plurality of inlet channels and the plurality of outlet channels in each individual channel unit having common porous walls.
