HealthyHome Tip
A Corsi-Rosenthal Box helps reduce airborne particles by pulling air through high-efficiency MERV-13 filters. While it can significantly improve indoor air quality, it does not eliminate mold growing inside a building or correct moisture problems. It should be used as one part of a comprehensive mold recovery strategy.
