4-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 at .3 micrometers. 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.
