The AC Infinity Activated Carbon Filter is a reliable option for odor control in grow setups. It effectively reduces the smell of cannabis, making it suitable for indoor grows. However, some users have noted that it may not completely eliminate the odor, especially when compared to non-refillable filters. The refillable feature is convenient and eco-friendly, but refilling the carbon can be a bit messy. Overall, it's a decent choice for those looking for a cost-effective and reusable solution1.
