Unlike typical fireplace vacuums that recirculate microscopic ash particles into the air, this model’s HEPA filter captures 99.97% of airborne particulates as small as 1/3000 of a millimeter. The HEPA filter is on the intake side of the motor, preventing fine, abrasive ash particles from damaging the vacuum or being exhausted into the air you breathe. The fireplace vacuum has a 600-watt motor that quickly suctions ashes through a 39"-long fire-retardant aluminum hose into a 6 1/2-gallon fire-resistant steel tank. The unit has an integrated handle and the lid simply unclasps to enable ease of emptying ash. For vacuuming cold ash. AC plug. 20" L x 13 1/2" diam. (11 1/2 lbs.)
