Customers are mixed about the quality of the fan. Some mention it's well-made, has a better quality metal frame, and has quality design and parts. Others say that it was poorly made, and only lasted 18 months. The filter is cheap and doesn't hold very well.

Customers are mixed about the air flow of the fan. Some mention that it's well constructed and moves a lot of air through a large carbon filter, while others say that it started rattling and stopped moving air through. The suction it produces makes the air output pretty loud.

"A little loud, but it moves a lot of air. So definitely worth it. It is also adjustable. We've had our for two years and it is still going strong...." Read more

"...No air was being pulled through. Humidity is very dry in my area <40%, so the filter shouldn't be clogged that quickly...." Read more

"...It is strong and pulls air. Almost too much ." Read more

Customers are dissatisfied with the noise produced by the fan. They mention that it makes a very loud rattling noise, a knocking noise that went away for a day or two, and then returned extremely loud. Some customers also say that the fan can be heard downstairs and around the corner. They also mention that the bearing starts to rattle and make a noticeable vibration, resulting in a hum that carried.

Customers are dissatisfied with the bearings of the fan. They mention that the bearing started going out about 6 weeks under constant use, making the fan make a loud noise.

Great working setup - but the provided accessories leave something to be desired

Great working setup - but the provided accessories leave something to be desired
PROS: There's quite a bit to like about this setup. Overall it works. I am setting this up in a 60x32x80 sized Vivosun grow tent, and once the fan and filters are in place, it immediately cleared up any residue odors that were left in my basement even when placed on the lowest setting. The noise is also pretty low, all the way up til you get towards med-high..... although even then it's not too bad (Maybe I'm biased though given it's in a basement lol). Assembly although manageable given the right tools for the job, can be a bit tricky if doing it by yourself - which then leads me to some of my cons with this productCONS: The two rust-free stainless steel clamps are great, but if you are working in a bigger sized tent than the one I outlined in my review, this may be a problem especially if you are looking to place this item somewhere on the inside. Although they are snug together...... a separate pair of smaller duct wrap and a secondary set of clamps would be ideal here to secure these two items in place. I don't expect mine to hold up and will be getting these items separately to complete my setupThe hangers for the fan seem pretty cheap and easily will detach and slide off if you are not careful with how you wrap it up against a support beam using their flimsy rubber clips. Vivosun should invest in getting some metal clip hangers like used on a Mars Hydro grow light to support something of this weight. It would put a lot of ease into people's minds when going to set this up. Also the fact that they only provide hanging straps for just one component, and not for both the fans and carbon filter baffles me quite a bit hereI'm only knocking off one star as these come off as minor inconveniences since I had some alternative tools for getting the job done. But from a product standpoint...... they should have extra equipment provided like I mentioned above to really help convenience their consumer base

5.0 out of 5 stars 2 years and counting
Reviewed in the United States on September 3, 2023
I got the 6 inch and Ive done maybe 5 grows to where the fan runs 24/7 for months at a time. The filter last about 2-3 runs. Using it in a 48x48x80 on the lowest setting and that’s enough to sink in the walls. It’s not the most quiet on the market but it’s not loud either. On full blast it gets a little loud. I would recommend the product because I’ve had it for a while and it works. 1 con though, the lip that connects the filter to the fan and the fan to the ductwork is sub-par.
