One of the best devices in this area, not only in my opinion but also in the opinion of most buyers, is the Husqvarna 350BT Gas Backpack Blower. It has an impressive capacity, and at the same time, it has a low percentage of carbon dioxide emissions in comparison with analogs. However, if you want to eliminate air pollution completely, opt for cordless devices like EGO Power + Backpack Blower. It has the best features among battery-powered counterparts.
