About VIVOSUN 6 Inch 440 CFM Inline Duct Ventilation Fan
Overall Feedback:
79% positive
81% appreciated the adjustable settings, but 19% found them confusing
The fan has a variable speed controller that allows adjustment from super fast to very fast.
I was attracted to this fan because of its adjustable fan strength feature that allows me to adjust the fan from low to high without the need for a separate controller. I also trust the brand for quality and customer service.
The speed control is almost useless with only a slight increase in speed towards the end of the turn and about 75% of the knob's range doing nothing until the fan is switched off.
81% liked its powerful airflow
I tested the flow output of the product without a load using a Testo 405i and it measured 203 CFM.
The fan has a higher airflow capacity than the 6 models, even when necked down to a 6 flex hose on either side.
76% praised its long-lasting durability, but 24% experienced premature failure
One of the fans has more vibration than the others.
I am concerned that the shiny, thin cover may decay or the housing will rust with any humidity, indicating a lack of durability.
I noticed the wire insulation was worn away and shorting from vibration.
There is a massive dent in the side of the filter that penetrates all the way through. The box was in perfect shape, indicating that the damage was done at the factory and they still packed it anyways. This suggests poor durability of the product.

79% found it easy to install, but 21% had difficulties
I installed it easily in just 10 minutes, including removing the old fan.
It took me some time to install the fan as I didn't need it at that time.
I wish the base of the fan had extended more in both lateral directions, which would have made it easier to install.
Installation is a real pain.
68% appreciated its energy efficiency
This product is energy efficient as it reduced the temperature from 33 degrees to 23 degrees and stabilized everything when installed at the top of the tent and vented to the attic.
After installing the fan halfway from the dryer to the exterior wall, my clothes dried in normal time and the exhaust pressure outside about tripled.
71% appreciated the mounting options, but 29% found them limited
I used a piece of styrofoam to stand the product on as the mounting bracket was included.
My only complaint is that the mounting bracket is too short, but I won't knock a star for it.
72% liked how quiet it operated, but 28% found it too loud
With the configuration shown in the review photo, I measured the sound level at 61DB, which is acceptable.
The noise level is a bit louder than desired, but it fades into the background quickly and is probably as loud as most HVAC forced air fans would sound.
The fan's noise level is too loud for a bedroom. I measured it and it was making 80-85 dB of noise.
The noise level is louder than expected and can still be heard from the first floor.

78% were satisfied with its safety features, but 22% found them lacking
I warned that the fan is a safety risk to our family.
I found that the product is unrepairable and there is a risk of fire due to shorting.
I warn not to mess around with exhaust as it nearly killed my plant.
I noticed that one of the fans is starting to make a subtle vibration/rumble/hum.
