DESC: We’ve never seen such a handy size air cleaner with three technologies: electrostatic filtration, ozonizer, and UV (ultraviolet) lamp. It easily carries from home, to office, to car. The electrostatic filter traps tiny polluting particles, and the cold cathode UV-C lamp works two ways. It zaps germs and generates ozone to help reduce odors such as tobacco smoke, gasoline fumes, cat litter, nursery room smells and more.
