The Filter Box is placed in line with your intake fan to remove unwanted pests and contaminates from being drawn into your grow room through the ventilation system. This is especially important if intake air is being drawn from outside as it is almost certain that it will contain insects and contaminates that will cause problems once inside the grow room.

• Contains a removable EU3 grade filter panel that can be periodically cleaned and replaced.
