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