Purchased a vivosun 4 inch and it crapped out in a few hours. I run this almost at max speed 24/7 for about 4 5 months at a time. Still hasn't quit.

This is my second one. I now own two. They are super quiet. They are well built. They are worth the extra money. I wasted money on a cheaper one that howled and make too much noise. You can't get any more quiet than this fan.

The noise level is just fine. But doesn't work for long. Really easy to use and the remote is a good addition but even with using it less than 6 times, it no longer works

Just bought our first cannabis grow tent, and went with AC Infinity after researching a half dozen different brands. The reviews on this fan were great, and the price wasn't too bad, so we bought the fan, filter, tent, silencer, hangers, advanced control unit for the fan, and glasses from AC Infinity. I couldn't be happier. It's built well, it's quiet even on the high speed (even without the muffler), and we like how the 67 control unit can be set up to take care of the humidity and heat without constant monitoring. And my wife used the app that comes with it so she can check up on things on her smart phone. (I have a dumb phone, by choice, so I have to go down in the basement to check it). Anyway, this is a really nice fan. It even looks good!

I have 2 of these 4-inch fans. One is hooked up to a filter and is exhausting a 2x4. The other is my intake for my 4x4 with a 6 and filter for exhaust. Hands down the best fans. Get controller 67, not the one bundled with fans. It's better and has an app.

we purchased the T series with the programable monitor and this will go nicely with that set up

I bought this 4” inline booster fan because there is a very long duct from the dryer to the exit out of our rental cabin This caused the modern dryer to overheat and shut down. With access in the basement I installed the fan right up against the exit which restored flow very well. The fan has 8 power levels but I has only used it on high. The downside is the control which is on a long (about 10ft) cord but I have to go down to the basement to switch it on or off. A pressure switch would be a better choice buts adds almost $100 to the cost. The device is held together by two straps which are easy to remove so the device can be disassembled for cleaning. It is very quiet. Highly recommended!

I guess you can keep buying the $79.99 one.You will learn the hard way. like me!Short and sweet because I don't do reviews often unless I am feeling obligated this item is by far more than exceeded expectations Yes it turns back on after you lose power Yes it pulls much more air than any of the other $79 fans at this price point this fan is by far the best ever ever ever I bought two.Not one regret if you're unable to come up with the extra money wait!This fan is night and day from the others you're comparing to.Excellent job Infinity

I am using this fan to help exhaust my boats adapted window air conditioner unit. It has been doing quite well with very little noise levels. It was quite easy to adapt to this application. I am sure this product can be used in a multitude of projects requiring enhanced airflow. I can't speak for its durability since I haven't had it working for too long. I will also add that I was very satisfied with the packaging and delivery of this product. As for a con, I would recommend having adequate space for the placement of this fan it is quite wide in the center. For me, that wasn't a con, but it could be a problem for those not having sufficient space, so make sure to take measurements.Over all, I totally recommending this product and company.

These fans are soo good and I wouldn't buy any other brand. I just got my third fan today since I love how quiet and reliable they are. I have 1 in my flowering tent, 1 in my veg tent and another in my closet. They use a lot less electricity than cheaper competitors and will save you money long term because of this. With my grow setup I try to use as little electricity as possible so to me These fans are easily worth the money. When you run these fans 24/7 then quality and power consumption are a big deal.I recommend AC infinity fans over any of the cheap junk fans for $50 or less, especially since you'll be replacing the junk fan in 6 months or less and in the end will be paying more than you would have to get the AC infinity fan.
