FhreshFlow HEPA Filters with Activated Carbon
Improve air quality in the grow area with GrowBright FreshFlow HEPA Filters. GrowBright high-efficiency particulate arrestance (HEPA) filters remove 99.97% of airborne particles 3 micrometers or smaller to prevent insects and other particulates such as dust, mold spores, and pollen from entering grow tents or grow rooms through the ventilation system. Infused with activated carbon, GrowBright FreshFlow HEPA filters also offer additional protection with VOC/odor-blocking capabilities and can be used in conjunction with exhaust fans to contain ensure pollen containment or for treatment of moderate odor levels. FreshFlow HEPA filters install easily over rigid duct/flanging and secure tightly with a rubberized collar and steel clamps for a proper seal.
Super Easy to Install and Maintain:
To install, simply slide the rubberized inlet collar over the inlet (or outlet) vent port of your grow room ventilation system. They may be attached directly to a high-velocity inline fan, rigid tent flange, Air-coolable reflector flange, or ducting. Secure the filter by tightening the worm type clamp provided. This, along with the heavy duty rubberized inlet collar, will create a good air-tight seal.
Which filter size and type is best for me?
The size and type of your ventilation system will help determine what size you need. Typically, simply matching the size of your fan/ventilation system determines the size of your filter. Example: A system with a 6″ high-velocity inline fan would require a 6″ HEPA filter, and this is what we recommend. However, it is believed that these HEPA filters operate efficiently using a higher CFM fan than typically offered by those corresponding to the size of the filter. Meaning, a 6″ HEPA filter could be used for a system with an 8″high-velocity inline fan. The decision is yours, but please note that you can either match the fan/duct size to the HEPA filter or go with the next SMALLER size. Again, we recommend simply using the same size HEPA filter as your fan/ducting ventilation system.
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.
