The Lightning Air LA-3IC is a heavy-duty air purifier designed with the professional in mind. By using a powerful O3 generator, this industrial cleaner internally produces activated oxygen and disburses it into the air, quickly removing strong odors and other pollutants at their source. Easily controls odors from pets, mold & mildew, decaying matter, cleaning fumes, cooking and more. Covers up to 8000 sq ft; use only in unoccupied spaces. Portable, it can be moved easily from one problem area to another. The durable ceramic plates are easy to clean and maintain.
