VIVOSUN 4 Inch Air Carbon Filter Smellines Control with Australia Virgin Charcoal for Inline Duct Fan, Grow Tent, Pre-filter Included, Reversible Flange 4" x 12"

This is a game changer. Looks amazing and the build quality is top notch. the air flow is great even with the sleeve on it. this isn’t the cheapest filter on the market but you pay for what you get, and this speaks for itself. I use this to get rid of the smell of my plants and it completely eliminates the odor. however i actually bought a second one to use for my soldering station to filter out the lead smell and possibly particulates from the air above my work station and it seems to be doing the job perfectly. this not the cheapest, but certainly the best 4 inch filter on the market.

This does what it’s supposed to do - reduces smells and looks good doing it. 4” flex tube clamps on without a problem. Not much else to say!

This really works and well too.

I bought this to attach to the air extraction for my fiber laser! My goal was to pull the smoke off the product to not leave residue on the projects! This was a great addition. It help filter probably 90% of the smoke out and didn't leave me, or my room smelling like smoke when I was done. Only left at 4 starts because it did still leave some residue but it was reduced almost entirely.

works very well

I bought this for my indoor garden. Runs quietly, filters the smell, easy to clean. The cover can be washed,. Excellent service.

So far, it is doing its job. Fast delivery and easy hook up if you size match everything. In my grow setup I have the Vivosun tent, 6”fan, and 6” ducting.1st setup I tried the filter siting on the ground (intake option) outside the tent with the fan on top and the ducting to the tent. Saved space, the fan fit right into the filter, it ran decently quiet but, when I got close to the filter I could smell a faint plant/flower scent. 2nd and current setup is the filter inside the tent hung above the plants. (A little scary because this thing is heavy) Then ducting straight to the fan which sits outside tent. I smell nothing coming out of the fan and the fan doesn’t seem to be working too hard, though I do notice a little more restriction this way. So my verdict. Out of the box the filter kills the Mary Jane smell. The filter seems to flow effortlessly as a intake filter, but works more effectively as a exhaust filter.I am a happy customer.
