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"

I use this in the winter to purify and deodorize the house in the winter. The air can feel pretty stale after being stuck inside all winter. I just connect this directly to my blower and run it in whatever room needs it. Truly feel like it cut down on our sickness and made the air feel light and fresh! Throw a dryer sheet on the output side and it smells like spring all winter.

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

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.

Great for front room,I use for 60days with filter cover,then toss cover and use 60 more than depose.

Awesome
