VIVOSUN Inline Fan 6 Inch 440 CFM with Speed Controller, 6 Inch Carbon Filter and 8 Feet of Ducting, Air Filtration Combo for Grow Tent Ventilation

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.

Top.... Too much for my Tent. I get it in sales, very powerful 💪💪💪

Changed to a 5 Star review. The fan did not break on me. I found out that it has a heat sensitive off switch to prevent overheating. Plugged it in today and it worked fine. Is a good product and I will update later if any other issues. DO NOT BUY. THIS UNIT BROKE AFTER A MONTH. NOW I CANT RETURN IT. BUYER BEWARE.

Fantastic fan for my grow ten!. Small issue is that it is only 2 months old and it seems to have gotten much louder.. otherwise it is going exactly what I wanted it to. Other than keeping my wife and I up at night as it now vibrates the floor which it never did before..

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.
