The performance of an air cleaner depends on the outdoor air change in the space where it serves. The results of that study reveal that when the outdoor air change rate of that space approaches the clean air delivery rate of an air cleaner, the efficiency of the air cleaner declines. Inversely, as the clean air delivery rate of an air cleaner exceeds the outdoor air change rate of the space it serves for by more than four times, the air change of that space has practically no effect on the air cleaners performance.
