VIVOSUN 4 Inch 203 CFM Inline Fan with Speed Controller and Leather Sheath, 4 Inch Carbon Filter and 8 Feet of Ducting, Air Filtration Combo for Grow Tent Ventilation

This was by far much better than I expected. I expected a home product and this is commercial grade and works that way too. The fact that it has a fan speed and can turn it all the way down seeing I don't need that much power lol, makes it perfect. I have the power when and if I every need it but I don't have to worry about running it 24/7 because it was obviously made to do this. Thank you!!!

Got this as a present for my brother in law, completely eliminated the dank smell from his room. Fan is a little loud even on the low rpm setting but that should be expected for the amount of suction it generates. Much easier to install with two people so get a friend to help you rig it up.

This seller ships very quickly. Super convenient! I got the 4 inch fan filter and ducting kit and appreciate how it all fits together easily. It is for a 36x36x72 grow tent. Originally I got a 6in but found it too much for my needs and the return process was very easy. The installation instructions are lacking but I figured it out just fine.

I’ve had this since 2019 and still works great it’s powerful as heck it will literally suck your tent ⛺️ in like a juice ???? box if you put it on high only thing is after awhile you need to change out filter because I can start to smell my baby’s when I walk in the door ???? but it is well worth the money!!! Noise level is quite!! As well

Great product! I was worried about noise etc from other reviews before I purchased and I have had Zero issues. Noise is exactly what I would expect from a fan. Also this was so easy to put together, hang up, and get running. This doesn't get used much, but when it does it works great. Good job vivosun!

Easy to install, glad it came with the aluminum tubing and 2 clasps. The fan is too loud to have in the room during sleep, but gets the job done. The filter works great no smell of anything ever. Works well on my 2nd grow, just wish it was a bit quieter, it only bothers sleep. Cant hear it anywhere else even when the door is open.

It seems to run great so far. Went together easy. When mounting the filter to the fan I had to add relief cuts on the filter so the clamp would hold.Still a great product.Update !!!!!!!!!!!!!!Two months of using it the thing is screaming.Obviously the bearings are bad and obviously I didn’t see the other reviews saying they will go out. They are not lying. It will fail. Do not buy!!!!Update. After a few days we are now getting somewhere. Hopefully they ship a new one.Update they did ship a new one. Hopefully this one lasts!!!!They do have pretty good customer service!

I've been running this for a while now and still runs as new. Husband put this is in my personal tent and i must say i love it. Runs quiet and has adjustable fan speed on control slider. Build on all of it and quality is above all, professional quality for half the price. Vivosun is our go to for anything that our gardens need. LOVE THIS SETUP COMBO!

Everything seems to be working fine, but it really grinds my gears that there are only two clamps included for the ducting... that was enough to connect the fan to the filter, but now I will have to go out of my way to drive across town to buy a .50 cent clamp to finish the setup...

didn't get anything I was supposed to
