Bring a breath of fresh air back into your home.Trap dust and eliminate household odors with the Hamilton Beach TrueAi Odor Eliminator. The TrueAir's quiet fan pulls air in and neutralizes odors through three carbon filters, sending fresh air back into the room. Measuring just under 8 inches in height, and using less energy than a 15-watt light bulb, the Hamilton Beach TrueAir Odor Eliminator can keep a 10' x 10' room smelling fresh for up to three months. A two-speed adds better control. Use the low setting for quiet evenings and the high for making quick work of dusty or smelly rooms.
