  • Sturdy and powerful fan, don't let the plastic assembly fool you.
Style: R6 6 Inch
So, I'm using this fan as part of my custom built ventilation system in my basement room converted to a cigar room. I use it to suck the cigar smoke out through the window via the 6 inch hose and some ducting that goes out. I use it in conjunction with a duct fan that's hooked onto the HVAC ducting that acts as an intake fan for the same room. What I like. 1. The speed controller comes attached. No need to purchase one separately. 2. Durable. I had a mishap where I accidentally dropped it from 7 feet to a concrete floor. No problems, turned it on and fired right up. It's plastic on the outside, but the fan itself has some good heft to it. 3. Powerful. This thing cleans out a room fast. You can watch the smoke going from the cigar a good distance away in the room as it goes right to the area of the fan. What I don't like: 1. This thing is loud. But, that's the compromise. If you want a proper fan that will do the job, noise will be on the table. That all said, it's not loud enough to drown out conversation or music on a small speaker in the room. Further, it's powerful enough to run on low and still keep the room clear with one or two cigar smokers. In all, this being part of my ventilation system saved me hundreds of dollars by not buying a rabbit, or any other overpriced smoke eater. Good price, quality fan. ... show more

The Ventilation Kit turned out to be quieter than I initially anticipated, which was a pleasant surprise. It efficiently vents out my tent, ensuring excellent air circulation without any disturbances. This unit has been flawless—I've encountered zero issues. Assembling and hooking it up was a breeze, adding to its overall convenience. If you're looking for a quiet, efficient, and hassle-free ventilation solution, this kit is an absolute winner! ... show more

  • Super loud, awful, whine!! *Updated Review*
Style: R4 w/ Carbon Filter
*Updated Review* After my initial review (see below), Vivosun contacted me and offered to send a free replacement. I took them up on their offer to give it another try. I did order a replacement fan that is super quiet and works great after this try, which is what I had been using. However, I was willing to give this one a try to see if maybe I did just get a bum unit. I got the new unit and plugged it in. It's definitely not as whiny as the original one, but still quite a bit louder than the other one I got (AC Cloudline Infinity). That one is also 2x the cost, but if you need silence is worth it. Overall I think this one is OK if you're on a budget and don't mind a little noise. If you have the coin and need things as quite as possible - look elsewhere. I did update from 1 star to 4 stars because of how well the customer service has been. This is still, at best, a 3 star product compared to other options. I set up a grow tent this year for starting seeds indoors before transplanting into the garden. I wanted an exhaust fan to be able to vent in fresh air to ensure air flow and good photosynthesis. I purchased a Vivosun tent and was generally satisfied, so purchased this fan to go with it. I received it and everything seemed pretty high quality at first glance. I got it installed and turned it on only to be greeted by this awful, loud, high pitched whine. Didn't matter the setting, didn't matter if it was connected to the filter, consistent loud whine. To its credit, it did seem like it moved a decent amount of air. If I had this out in a shop or in an attic it would probably be fine. But for indoors in a house, absolutely not. No way I could work from home with this torturous, piercing sound in the background. I ended up returning it and replaced it with an AC Infinity Cloudline fan. That fan w/o the filter was as much as this combo, but it's dead silent. Not sure if I got a defective one, or if that's just a price you pay for this cheaper version. But if silence matters, spend the coin for a better one. ... show more

  • Yes, it's a little loud
Style: R6 6 Inch
Yes, it's a little loud but compare the CFM's to others. This thing moves a lot of air! If the stink is a concern more than the noise, (Not that loud.) then this is the fan you need.

  • Exactly what I was looking for
Style: R6 w/ Carbon Filter
I was looking for something that could suck all the air on my laser cuter as well as remove all the fumes. I saw a air scrubber that was 3 times the price and super loud, and this. I purchased both. This is by far the easiest setup and most quiet. It has about 400cmf suction and the carbo will absorb any fumes that might be coming out of the cutter. The outside sock will also prevent any dust from exiting. The only thing I worry about would be if an ember was to be sucked in, but since the canister is steel I think that it would be snuffed out before it even had a chance to penetrate the outside. Over all for the price and size I think it is an awesome configuration. ... show more

  • Decent flow

  • Good power to noise ratio, easy to relocate speed controller with basic knowledge.
Style: R8 8 Inch
When I purchased this I wanted to know more information about type of motor so I could control the speed from a normal switch box on the wall (the fan will be in the attic providing kitchen exhaust). I never figured out if the motor is induction, shaded pole, or brushless (in order to get the correct speed controller), but now it doesn't matter because I'll just use the provided speed controller. It will be very easy to remove the controller, drill a hole in a blank faceplate, and mount it in a normal switchbox on the wall in our kitchen so I don't need to crawl into the attic every time to adjust the speed. I hope this helps someone else out. ... show more
