10-Inch CleanFlow HEPA Filter.

Improve air quality in the grow area with GrowBright CleanFlow HEPA Filters. GrowBright high efficiency particulate arrestance (HEPA) filters remove 99.97% of airborne particles 3 micrometers or smaller to prevent airborne contaminants from entering grow tents or grow rooms through the ventilation system. Highly efficient filtration with excellent airflow also makes GrowBright CleanFlow HEPA filters the most effective option for keeping expensive air-cooled lighting equipment clean and free of debris. CleanFlow HEPA filters install easily over rigid duct/flanging and secure tightly with a rubberized collar and steel clamps for a proper seal, and they can also be washed as needed for extended life. Simply remove and spray with a water hose to clean.Please Note: HEPA filters are recommended for use with high-velocity inline fan or blower fan units as they may create too much restriction for smaller fan types such as duct booster or small axial fans.
