Galvan: Envío más rápido de lo esperado, todo funciona bien hasta ahora

DaltonDalton: 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.

Chris : I have the vivosun 4” kit as well as the ipower 4” kit , to start the vivosun fan is 10x better, much quieter and better quality metal frame, comes with a dust jacket, and it’s adjustable, the ipower is this cheap plastic fan that’s not adjustable and it’s kinda loud, I think the plastic housing produces harmonics that causes that! So anyway it’s a great setup for the price, not sure of the filters yet but both have decent reviews as far as removing odors

Ellis Parsons: Suction power is excellent. Noise is not bad. Can watch TV or listen to radio no problem with blower going.

David A. Hill: Pros: Overall build quality was very satisfying. Fan housing is steel and is fairly heavy for it's size. Included duct was of good quality (expected less honestly - pleasantly disappointed😁👍)
The filter is huge. I didn't expect that. In all fairness, I just knew to buy the 6", I never looked at the measurements.
I smell nothing outside the tent and I use fish emulsion (this $#!t sinks).
It also has a potentiometer for speed adjustment.

Cons: I had to cut a piece of wood to bolt the fan to because, while it does come with a bracket and nuts and bolts, it doesn't come with a way to hang it inside the tent.
Also, the filter is bulky and a little heavy to hold overhead and hang by yourself. YOU'RE GOING TO WANT A SECOND SET OF HANDS (Yeah, you can hang it yourself, but if you have an anxiety disorder as well, just save yourself the frustration😤🤬👍)
Only other con is the noise level.
If the door isn't shut to that room, the fan can be heard downstairs and around the corner.

Other than that, 10 out of 10 for performance. Would buy again if I needed another.

Ghost: Easy installation, complete kit. Worked great for 3-4 months. Then steadily making more noise. Bearings are failing. Not sure how to get warranty? I can’t find any contact info for VivoSun.

Peter S.: Edit: I left the review below, but soon after I contacted Vivosun. They responded very promptly and are refunding it. The faulty one actually did last for the warranty period, failed one day after. The company does a great job responding to issues and trying to make things right. I will continue to buy their products.

I bought this exactly a year and a day ago. I've used it off and on, but more in the last couple of months, running on the lowest setting. It has worked fine as far as moving air. It's fairly loud when operating normally. But, today it started making a really loud sound like a bearing had gone out or something. I could hear it from the basement to the upstairs. I wrote this same review on the individual fan item sold on Amazon, but posting it here, as this kit is what I actually ordered.

tammy haryett: For indoors it is very loud. Would be better in a garage or separate room. Otherwise great value for the price. Would recommend.

Phil: I used this fan for around 5 months. The first 3 months went decently well, the suction was great and noise level wasn’t too loud at the lowest setting. Then came month 4... the fan now barely works and makes the loudest noises I’ve ever hear from a fan like this. I’ve used other fans that can last up to two years with little to no problems. Just last night I heard the fan stop completely on it’s own and made a screeching noise like it was grinding. I checked the fan with no obstructions and tried to turn it off then back on, it’s barely working and EXTREMELY loud im scared it’s going to blow up or stop working when I’m not around for a few hours. Hopefully im able to get a replacement or a refund as I’m just hitting early flower and this is going to be a problem.
