When the forest fires were burning one could barely breathe the air outside. However my two Air Doctor 3500 units made the inner air breathable. The machines worked hard and struggled to clean the air. It took a long while, but eventually the monitor lights turned from red to orange and finally to blue signifying that the air was optimal ot st least good enough to breathe. . By design, the machines are pleasant enough to look at, but what I appreciate is their simplicity. They are easy to operate and maintain.
