iPower 4 Inch 195 CFM Inline Fan Circulation Vent Blower, Air Carbon Filter and 8 Feet Flexible Ducting for Grow Tent Ventilation, Exhaust, HVAC Heating Cooling

I’ve been using the iPower 4 Inch 195 CFM Inline Fan for over a year now, running almost constantly, and it hasn’t missed a beat. From day one, it worked exactly as advertised and it's still performing just as well today—no slowdown, no noise issues, no drop in airflow. The fan runs quiet, with a clean and low sound that doesn’t get in the way. Even after long-term use, it hasn’t developed any rattling, whining, or vibration. It’s been one of the most consistent parts of my setup. The filter that came with it is still in good shape too. I check it regularly and it hasn’t degraded or clogged up like cheaper filters tend to. That alone has saved me money and effort on replacements. Installation was easy, and it fits cleanly into a small ventilation setup without needing any special adjustments. Whether you’re using it for air circulation, exhaust, or passive cooling, it just works. For the price, the performance and reliability you get are seriously good. You’d expect something this quiet and stable to cost more. After a full year of continuous use, it’s proven itself to be a solid, low-maintenance investment. If you want something that lasts, stays quiet, and handles real-world use without failing, this is a great pick.

As a newcomer to indoor growing, the iPower 4-inch 195 CFM inline duct fan has been a game-changer for me. It provides the necessary airflow to keep my plants healthy and thriving. The installation process was a breeze, thanks to its compact size and easy-to-follow instructions. The fan operates quietly, so it doesn't disrupt the tranquility of my growing space. I've noticed a significant improvement in air circulation and temperature control since using this fan. It's a reliable and affordable option for anyone starting their indoor growing journey, and I highly recommend it for its performance and user-friendly design.

I was hoping that it would have better suction. I use it to remove fumes from soldering for stained glass studio. It works but not very well.

Good little fan !

Nothing fancy here, just a basic inline 4" fan. I think it would be great for a small indoor garden. Might be too small for a 4x4 though. I have a 5x5 and use it to pull the co2 off of the floor and recirculate back up to the ceiling and over the canopy. It works great for that and is small enough to not get in the way of the plants since it sits on the floor. Its small, but powerful for what I need it to do. There has been an increase in co2 in my tent, because co2 is constantly moving back up and not pooling on the floor and leaking out the bottom of the tent. The best part was it had everything you need including the duct, and pre-filter for the carbon filter all for a surprisingly low price. It really made me feel good that a brand that I am familiar with was also the least expensive option.

it runs basically the whole time the light is on. and it doesnt vent enough. i was expecting a little more. the controller reader piece, its perfect. the wifi, bt feature actually works. it doesnt give a proper alert though that the area is too cold, or over hot though. i wish it would little beep or so warning. just didnt vent enough. i had to use extras to help it. 3.8 of 5. i just expected a lil more. but it works and does the job.

This fan is doing the trick. I have it running in two 3x3x6 ft grow tent in a research lab. Noise isn’t an issue for this reason, but when the tent is sealed, the noise is very modest. I’ve been running it 24h since purchasing several weeks ago and haven’t encountered any problems. The only tricky bit was mounting the charcoal filter and fixing it to the fan. I used heavy duty zip ties for this and cut a portion of the included duct. I had to purchase an extra hose clamp as this only comes with two - you will need a third, as well as wire snips to cut a piece of duct. If you’re looking for a cheap inline fan, I recommend this one.

I have a 2x2x4 grow tent. The suction is a little too much because it sucks the tent in. The tent is still strong enough to handle though. I have the fan on a timer that goes on every 3hrs for ½ hr lengths. This gives the tent some time to inflate again and saves on electric. I have a small oscillating fan for cool air circulation. When unboxing, I noticed the front cover of the fan comes apart easily. After several hours (4-5) of running it the cover came off. I had to reinforce by wrapping tape around the edge to make sure it doesn’t come off. It’s over a month now and it runs perfect. The fan can be heard very little, especially at night when it’s super quiet . The set up was fairly easy. The biggest decision was whether to set up everything inside the tent or outside. I currently have everything inside because my plants are still small. But I’m probably gonna have to move it out once the plants gets bigger. This is my first attempt ever, at using a grow tent with all these extras.
