🌬️ VIVOSUN 6 Inch 440 CFM Inline Duct Fan with 6"x18" Carbon Filter for Odor Control - Premium Australia Virgin Charcoal Included Review

I was very impressed with this fan and filter combo when I bought it 5 months ago, but in the last 2 months the airflow has dropped to less than 10% of normal. I removed the pre-filter, took the carbon filter out of my tent (not an easy feat), vacuumed it with my shop vacuum, blew it out with an air compressor, and hung it back up. The next day the airflow was back to about 50% of normal. 10% airflow or less! With other brands, it took over a year before I even noticed a drop in airflow. For…

I AM VERY SATISFIED WITH THIS VIVOSUN SET! I can confirm that it was quieter than my previous set and seems to work like a charm - it's a huge upgrade from my last combo set and I'm excited to use it in my Vivosun 4x4 grow tent! There is noise though (because I also saw that they sell silencers on their website which people are raving about and I will try to make them even quieter. I am in the early stages of installing my new grow tents so will I will be sure to update the lifespan of this…

Since the reviews on this product are so clearly divided, I decided to try my luck. Unfortunately, my happiness sucks! Although it's not calibrated, my dB meter reads 58 dB at 3 feet from the fan, while the description says 50 dB. This may sound like a minor inconsistency or that it is within an acceptable "tolerance", but it is not. Sound measured in dB is logarithmic (see) and therefore an 8dB increase is actually almost twice as loud (10x louder, but the perceived loudness is about twice as…

I really liked this filter. Supplied in an unmarked box. Almost immediately I took in all the scent from a 5 x 5 foot tent with 4 plants. strong negative pressure in my tent. Walls stretch pretty well when they're low. It's fairly quiet and not very loud when set to medium or high, depending on your needs. For example, my house has only one floor and it is in my guest room. You can barely hear it if you stand outside the room with the door closed and focus it on a low level. Turning it on I've…

Received the fan and canister and am pleased with the build quality and performance. Happy with my purchase. However after 7 months the fan started to grind and rattle (still runs but very noisy), it looks like the bearings have failed. However, I contacted the company with the issue and they responded and found a great solution within a week (after some communication and video transmission of the issue). Due to the size of the device, it made no sense for the seller or me to send it back by…

Fan and filter arrived very well packaged. No damage or shipping problems. I installed a 6 inch fan and filter in a 4x4 grow tent from the same VivoSun company. I used the fan for a few days without a filter to test everything. The fan moves the air seriously, even on the lowest settings. Cause negative pressure in my grow tent if all vents are open! The fan is a bit noisy without a filter. After you set them up and plug them in, the filter quiets the fan considerably. I chose to connect them…

I couldn't even hang this filter in a Vivosun brand tent before it started falling apart (the green strips holding the outside of the filter loosened and the material starts to shrink). Additionally, the adapter is over 6" in diameter at the end and is so perfectly smooth that even after deforming the 6" flexible slip-on vent hose and then tightening the screw clamp, any deviation from the perfectly horizontal position will instantly slide the hose off . Also, the two ridiculously loose…
