Duct Opening: 4” | Length: 13" | Airflow Rating: 210 CFM | Carbon: Australian RC412 at 1200+ IAV | Thickness: 38mm
I have been running it with the cloudline s4 from A.C infinity.
First impressions were good. Appealing look to it, seemingly well built and no excess charcole dust on the inside. I hung it while in early veg and even though the plants were quite smelly later in veg, the filter done a great job at eliminating the smell.
However, by week 5/6 of flower you could smell my grow everywhere upstairs. It wasn't as strong as opening the tent but still very noticeable. Made sure there were no leaks in the ducting and always had negative pressure. These plants were pretty stinky but i wouldn't have expected them to kill the filter. I have also read a few reviews from people that have had similar experiences.
Overall id give it a 7 out of 10. Would probably be great as an intake filter or a filter for a prop tent.
