Chimfex Chimney Fire Extinguisher

Help protect your home and family with the Chimfex Chimney Fire Extinguisher that is used by homeowners, professional firefighters and chimney sweeps nationwide.

Chimfex has been designated a CSIA-approved product by the Chimney Safety Institute of America.

To activate Chimfex, just drop it alongside the fire, then close the doors or intake vents for the chimney or wood-burning heater. In just seconds, the robust smoke from Chimfex rises up the flue, replaces the oxygen and smothers the fire. In addition, the temperature of the chimney flue drops dramatically - by more than 50% according to independent product testing.

Each box measures 14.25" x 1.5" x 1.5" inches

Not only will homeowners be happy you've protected them from the potential loss of their house, you will have also prevented damage to the chimney flue or chimney liner by reducing the extreme temperature and by avoiding the use of water.

    Bought enough to give us confidence that we would be able to keep a chimney fire at bay should we get one. This is important insurance!
