Amazing!
I had an off brand in-line fan in my tent prior to getting this one. What a difference!! I love that there is a dial so I can control the speed of the fan. The old fan just didn’t have any power really and wasn’t up to satisfaction but this fan doesn’t even need to be on high. The lowest setting on the mars hydro in-line fan is about what the old fan did. This fan can I’ve some air inside your tent for sure! It’s also quieter even when on its highest setting! I’m super happy with this fan and would recommend it to anyone looking for a quiet, powerful efficient in line fan.

Reviewed in Canada on May 19, 2021
I got the 4" inline fan and carbon filter combo, and it goes well with the 4x2ft grow tent. The combo is mounted to the top metal frame, and doesn't take up too much space. It's doing a great job filtering all the air and eliminating all the odour without making too much noise.

Super easy to set-up and I recommend this to anyone who is looking to get a fan/filter set up for their grow.
