MELONFARM 4 inch Air Carbon Filter Smelliness Control with Australia Virgin Charcoal, Built-in 14cm Fan Low Nois and Speed Controller, Smelliness Scrubber for Inline Duct Fan, Grow Tent 4" x 14"

Ive used other more expensive 4" inline fans in the past for plant smells, but I bought this for a different purpose.... To remove soldering fumes.This fan is way better than the other 4" inline fans ive used, this has a very powerful high static pressure fan that really moves some air!Can control the fan speed with the dial/ potentiometer on the power cord.I opened the flange end to reverse the fan so that it sucked air in. Theres alot of loose carbon to clean up on initial setup but this thing works fantastic and has more power than more expensive fans. This fan/filter combo is also curently the cheapest option and works great so get it if your looking!

The media could not be loaded. EDIT: 5 Montha later still working flawlessly and still controlling very strong skinny odor.Due to mixed reviews I wasn't sure what to expect out of this. I got it today and I gotta say I'm impressed with it for the price .. it is true at 200 CFM and the controller works fine. No weird noises from the unit , the filter does give off some carbon charcoal but just let the fan run for a minute and blow it out and it's fine. Love that this takes up a small amount of space.

This came in a smaller box than a typical carbon filter, and in-fact, it is smaller than average. However this doesn't affect the performance. The fan is strong enough to create enough negative pressure in my tent when turned to 75% that it pulls the sides of the tent in. So I would say that cfm isn't an issue. As far as smell, I put it in there with some stinky plants in mid flower, and to my surprise, I can leave this running between 60-75% and it totally eradicates any smell outside of my tent. I was initially hesitant to buy after seeing some of the negative reviews, but decided that it's worth a $40 gamble. After having used this I tend to believe that some of their competitors may be had people spam bad reviews to drive sales their way. No, I can't prove it, and yes I may be incorrect, but I am 100% happy with my purchase and am thinking about buying another for my other tent.

Assuming it holds up over time, this is an effective scent filter and air mover for the indoor weed grower. It's easy to install, well built, and an excellent value. My tent is small (24"x36"x60") and I only need to use the lowest setting on the fan controller, so it isn't very noisy, but it is loud if you crank it up. IMO, it can easily handle filtration duty in a much larger grow space.

I was very disappointed upon receiving the fan I ordered. As soon as I opened the box, I noticed a significant dent on the carbon filter. However, what concerned me even more was the discovery that self-tapping screws—typically used to create new holes—had been used to secure the fan cover. Out of curiosity and concern, I removed the screws to inspect further, and confirmed my suspicion: instead of utilizing the pre-drilled holes on the carbon filter, new holes had been unnecessarily made directly into the material. It's surprising that this product is rated 4.3 stars—it feels more deserving of a 1-star rating based on my experience.

Use this in my room because it was cheaper than most air filters and honestly it's the best one I've owned

The picture makes it look like it comes in the ventos it does not The package that it comes in also comes destroyed it's the original packaging that send it over and in China I mean this is a decent $20 product not 50 though they're they're taking advantage of you

This thing is perfect for a 2x2 or a 3x3, really moves some air.
