Review: Works ok - Works ok fan was scech kept smell down
Review: Definitely worth a try, you will be happily surprised! - I have been growing in a tent for a long time. Usually, you have to get a charcoal filter and some type of air system to push or pull air in/out of the filter. With this filter, you don't have to purchase anything else for air flow. The built-in fan is a great idea. I have a feeling other companies will have similar products soon. I believe this is a game changer. This could help keep set up and maintenance prices lower. I set it up yesterday, the fan pulls way more air than I believe it would. I bought the 4 in size to go in a 18x34x62 grow tent. I currently have it set on the lowest setting possible and it is doing the job well. Was really shocked about that fact. I've had cheaper filtration fans and they had to be on full power and still didn't blow any air. Was easy to hang and install, just plugged in the power supply and was off and running. I really hope that the charcoal filter keeps smells down for a good amount of time. I highly recommend this to people with cost, of set up in mind. Could almost cut down the price by half, for grow tent filtration set up cost. I wish this product was out when I first started growing different plants in side.

### ⭐ Not as advertised, smaller filter than described, no fan, no ducting
*by J***N on August 23, 2025*

What should customers know? This item is not as described. The product info on the page and on the box indicate a 12" carbon filter, but this is actually about 9.5" **There is no builtin-in fan, no speed controller, no 8' of ducting per the description.** Everything in package seemed new and I expect should work okay. But double negatives for being misleading and just plain false -- intentionally it seems. I have purchased carbon filters from other manufacturers that are larger for the same price or less. Size matters here, smaller filters just don't last as long. I would not have purchased this item had I known it was smaller, would have purchased the coupler separately.
