VIVOSUN AeroZesh G4 Smart Air Filtration Kit Pro G4 4" GrowHub E42A In-Line Duct Fan WiFi Controller Carbon Filter and Channels Cooling System

This kit arrived with everything you need. Works flawlessly and having a digital controller adds convenience to the set up, easy set up too.

Einfache Montage, alles dabei was man braucht, unkompliziertes verbinden mit dem Controller. Ein herzliches Dankeschön an den Support, der neue Controller ist gut angekommen und alles läuft super.

Was on the fence after seeing reviews with broken and exceptionally loud fans but I got it. Mine is only a few weeks old but it's quiet, works well, and installation wasn't hard at all. Was packed well and shipped fast. The only reason it's 4 stars is cause I don't know how it will hold up over time.

Im sad about i can't give 10 stars. AMAZING! Quiet, efficient and working perfectly. Im very happy with it.

Great product. WiFi controller is very handy. Moves a ton of air. Only downside was filter can’t be mounted directly to fan. Both are metal so can’t use the supplied clamps. Should have came with a third clamp so you could cut a piece of flex ducting, or a rubber grommet to hold it together. Or foil tape to tape it together. Really anything.
