Nick Significant Upgrade
Much stronger than my old 145cfm fan. Now my manometer actually reads something when the fan is running. Seems to have lowered my average radon levels from 4.5ish to 2.5ish. hard to tell with radon as it constantly fluctuates but if your seeing less than an inch on your manometer and have a lower cfm fan installed you will likely see positive results if you upgrade to a higher cfm fan like this one depending on whe you currently have installed.

Șipoș Marius Ioan VEVOR fan 190cfm
Thank you for your attention to my problem with the confusion created on order, which was resolved quickly. Regarding the quality of the fans, the quality/price ratio is beyond expectations. This prompts me to highly recommend purchasing VEVOR products.

Drew Good for the price.
Okay fan. However, the manometer that came with it has very flimsy tubing that pinches, so I had to buy a 3rd-party manometer for $15.
