    • WORKS PERFECT
Size: 4 Inch RJ12 Speed Controller
Gets rid of all smells, helps with humidity control, really pleased thus far just set up today. Filter mounts right to duct fan but slightly loose, sealed with foil tape and a clamp for safety and is now snug/air tight. Placed the exhaust tube directly into a 4” duct boot/vent filled with dryer sheets for extra clean scent. Easy assembly. Worth the money. ... show more

    • Decent fan and filter, ducting leaves much to be desired
Size: 4 Inch RJ12 Speed Controller
Fan works well, moves a decent amount of air and isn't hugely noisy, filter is well built, the ducting diameter is smaller than the ends of both however and it takes great work to cut and work ducting to fit under rings but would easily fit INSIDE the openings on the fan but then there's no way to clamp on. ... show more

    • Great fan
Size: 4 Inch RJ12 Speed Controller
I have a 10x10 area wrapped in panda plastic and this fan on 30% will pull the plastic in. Air inlet opening is 6x4 inches. Works very well. If you are using it with a ac 5 or 10 controller make sure to upgrade the app and firmware the firmware is located in the setup of the controller.
