Review: Pretty impressive little filter - 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.
Review: Works well - Bought a few of these. Simplified grow setup. Definitely takes odors out of the air. I use one to purify my camp cabin air now

### ⭐⭐⭐⭐ Worth the price
*by A***R on September 13, 2024*

I bought this on sale for $39 bucks. It was well packaged and arrived damaged free. I was a bit surprised by the bulky weight of this carbon scribber, but in my mind that is a good thing, if it were light as a feather I would have been a bit concerned. The carbon scrubber was covered in a light dusting of charcoal so I decided to plug the fan in in my garage and crank it on high for about a half hour. When I was finished I dampened some paper towels and wiped down the carbon scrubber and then dried it. After that I placed the filter over the scrubber, and it was good to go. Moves air, does it's job.
