The recirculation kits performs multi-stage filtration and removes the odor from the gas and smoke that is sucked into the range hood, which removes harmful components and pollutants in the smoke, and effectively solves the problem of using range hoods in houses where the range hood cannot be exhausted. Do not try to clean the charcoal filter in the recirculation kit as it can not be cleaned, Please change the charcoal filter every 4-6 months (depending on hood usage)
