MELONFARM 4 Inch Air Carbon Filter Smelliness Control with Australia Virgin Charcoal, Odor Removal Carbon Filter for Grow Tent, Inline Fan, Hydroponics, Pre-Filter Included, Insulated Flange 4" x 11"

So far seems good. I don’t even need to use ducking with this. I have it connected directly to the in-line fan and this just sits right on top of the tent. My set up is so small and this is such lightweight. It works great. It doesn’t prevent airflow issues. It doesn’t stop the suction from the exhaust fan. The degree of pressure that comes out is the same. It’s just filtered which is ideal for gardening and I was surprised that the function for how inexpensive this was I definitely recommend it.

cumple lo que promete

De momento funciona bien, lo ocupe para una máquina de ventilación de láser.

Works good I like it it’s a little heavy but it’s literally a filter so can’t be that bad if you have a quality tent easy to use you slide the cloth over it and connect it to a fan

If it lasts a little while, seems like a great deal. Compact enough to get inside of a little tent if you need it, although I would probably just run it through the outside It has plastic top and bottom so try not to drop it.
