ABSTRACT:
This invention is concerned with a removable filter to prevent the buildup of Creosote in chimneys which become vulnerable to fires.
A hollow enclosure means that is adapted to connect between the chimney and the fire source has within it a support for mounting a filter. The filter is made of a special metal, is knitted with small openings therein permitting the flow of smoke but at the same time to reduce the particles into a minute white ash. The filter acts as a continuous burn reactor. A door is provided whereby the filter can be easily removed from the hollow enclosure and cleaned so that it can be used for an indefinite period without replacement.
