Customer Reviews for VEVOR 4" to 4.5" Radon Mitigation Fan System Kit Quiet 190 CFM Inline Duct Fan

Easy to install, powerful, great noise reduction. Excellent product!

Replaced older model. Easy to do on your own and is quiet.

Easy to install, good instructions, and they give you a full warranty for DIY, which isn't true for the other common brand

Fan installed easy with no problems. This fan had a much higher cfm than I needed. The orgional fan pulled 1.0 inches. This one was over 2.1. Lowered the voltage down to 75 vac with a variac, now it is operating at the same level. Very quite.

Easy install and the fan is very quiet .

Works like a charm , used this fan on a 1000sq ft basement utilizing the sump pit which I sealed brought the levels from a high of 12pCi/L to .3 and lower. As I’m in Canada I installed the fan in basement and vented out through the sidewalk as per Canadian recommendations. Fan is so quiet that I cannot hear it unless I’m in the furnace room where it is installed. Great fan, great price .
