Air Carbon Filter 4 Inch ,Smellines Control Removes 3X More Odors Contaminants. Australian Virgin Charcoal, Carbon Filter for Grow Tent, Hydroponics, Pre-Filter Included (4inch)

I only just set it up an hour ago and wow the difference is amazing. Im using it in combination with a Hon&Guan 4 inch adjustable vent fan set on low speed and its a bit hard to tell for sure yet but it seems like it has removed 95 percent of the smell, possibly all the smell if i stopped opening the tent. Product looks quality and functions like quality. Size is fine. Was able to tuck it inside my 2x4 tent along with the fan though I did run it upright with a 90 elbow so there is room for the light. Maybe the best $26 ive ever spent.Edit: after 2 weeks it means to be working less efficiently. Next time I will run 2 of these filter. 1 on the inlet side of the vent fan and 1 on the out side

Filters the air really well and was a great price.

First off, i like the color. Its not just basic silver/chrome like most others. Quality wise; it feels pretty sturdy and durable. Effectiveness; there's a clear as day difference now with this filter as opposed to just having the vent fan, and for the price its well worth it. The ratchet rope works well as intended and made it a lot easier to install and adjust if needed. I dont have any complaints with it so far its exactly what i wamted and needed.

The media could not be loaded. Very small. Great value for the money. Very durable. Does a great job eliminating smell. Keeps humidity low and is easy to use.

This thing does very little for blocking the oder, I can still smell the plants and there only in veg,this will be totally useless for flower time.

The only thing this is missing is extra hooks built into the carbon filter. Just makes it's a little easier to secure and hang. Really not a big deal at all. The other nitpick is this is just *Slightly* smaller than the tube it slides into.. so you have to play with it a little more. Overall I'm happy with it's performance and price and I would def buy it again.

Looks like great and solid build. Comes with an extra dust cover which is a nice bonus. Will be ordering these filters again. Very satisfied so far. Just need to see how long its lifespan lasts before needing replacement. As long as it lasts a good 2-4 months, I’ll be happy with it and will buy again in the future. Overall very please with price & quality.

Great air filter for all odors and smoke. Definitely worth it if you want to eliminate smell
