“As many would be, I was concerned if the ionbox truly cleared the air. So, I felt the real test would be my garage. Every morning when I stepped into the garage, I smelled exhaust. Even though the garage door had been opened during each day time, I still detected exhaust fumes. So, at bedtime with the garage door closed, I placed the ionbox in the garage. Sure enough, the next morning, there was no odor. Two days later, having not used the ionbox in the garage, the odor returned. So, one more night of testing proved again, the ionbox removed the odor. Yes, I am convinced!”
