This 6" flanged filter stands 18" tall and 9.5" wide! This powerhouse contains over 7.5 pounds of Activated Carbon (not cheap "cocoaa carbon" inside it's thick double walled steel construction! Comes with a white fabric Pre-Filter that filters larger particulates (dust, etc) before entering the carbon filter.
This 6" fan filter combo is perfect for modest medium sized grow room / grow tent / grow cabinets!
This Activated Carbon Filter is constructed with a "packed bed" design to give consistent performance, long life (12 to 18 months), and are completely maintenance free. The packed bed of activated carbon design prevents the formation of preferential channels which can allow untreated air through the system. This unique design gives the filter a larger surface area for significantly lowered pressure drops. In other words, it's a double-walled filter packed tight with carbon that allows for a large surface area with no "empty areas" of carbon that would allow air to pass through it untreated.
Effective treatment requires the exchange of air in the growing area in a period of 5 minutes. Compute your requirements by multiplying the width times the length times the height of your growing area to obtain the total cubic feet. Divide this number by 5 to determine the proper filter size needed.
For example, if your growing area is 8 feet long by 8 feet wide by 8 feet tall, it contains a total of 512 cubic feet. To treat this area in five minutes, you would need to use a fan with a CFM (cubic feet per minute) rating of approximately 102. The GrowBright fan that comes with this system is rated at 424 cfm so this combo is good for any modest medium sized grow room, grow tent or grow cabinet!
Please Note: It's always better to have a little more filtering than a little less for the best results. Please "do the math" and realize you may need more than the minimum recommendations to effectively remove all odors from some of the more fragrant plants being grown nowadays.
We also suggest using a Fan Speed Controller to "tweak" out your fan speed to customize the air filtration needed for your particular garden.
