Sweeping out the fireplace stirs up a cloud of ash that coats everything in the house; using a shop vac makes just as much mess. Now you can vacuum up ashes with this specially designed vacuum. The dual filtration system includes both a coarse-dust pre-filter and a fine-dust pleated filter, keeping ash particles and dust safely contained. Designed for vacuuming cold ash from wood stoves, pellet stoves and fireplaces. Not intended for use on hot ash; the vacuumed material must be below 100 degrees F.
