Instead of replacing the entire filter when the charcoal is spent, this refillable 8-inch carbon filter lets you simply replenish the activated carbon and continue using the same housing. Its patented chamber is engineered to deliver the same lab-tested odor filtration as standard carbon filters while eliminating the need to manually compress replacement charcoal. Designed for 8-inch inline duct fans, the kit includes everything needed to perform future charcoal refills with minimal effort.
Perfect for:
Grow tents · Hydroponic systems · Indoor grow rooms · 8-inch ventilation · Air odor filtration
