The Stealth Carbon Filter will filter your grow system simply by covering up the fan port with a 2 inch thick carbon filter system. Filters smell, light & noise! The filter mounts easily. Simply peel the sticker cover and stick against the open port to block it. From there, the filter will catch all odor and even a lot of the noise with 2 inches worth of carbon filter. This works perfectly with standard sized 80mm-120mm computer fans but can work with any fan port.
