VEVOR 4 to 4.5 inch Radon Fan Installation Kit, Quiet 260CFM Radon Mitigation Fan System Kit with 2 Couplers, Pressure Indicator, Waterproof Inline Duct Fan Exhaust Fan for Indoor Outdoor Ventilation

Great price/quality

This is an excellent, well-built radon fan. Installation is quick and easy. Fan comes with a pressure gauge.

Worked great and is A+ for its purpose as a soil mitigation or radon mitigation fan.

I bought this radon fan about a year ago but never got around to installing it because my existing one was still working. The existing one was getting noisier and noisier, so I finally changed it. It was easy to install and is much quieter than the old one and there is no vibration. I checked at the outlet outside, and it is moving a lot of air. So, I am totally satisfied with this radon fan. It seems to be well-built also.

Super quiet for indoor basement installation! I was amazed at how well it worked & really impressed with how quiet it is!! It’s very light, super easy installation & it fixed our passive radon mitigation system overnight!

My husband was able to install this himself, the instructions were easy to follow and after a trip to the hardware store we had everything we need. We have our radon reader still set up and it works really well! So happy this worked! Way cheaper than the one at the store by us, which is funny because we read the UPC and it is the same unit.

Good product will buy again. Seems like build well and shopped fast too. As I use more we will see how long it last.

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.

We had a new radonaway brand system installed in our house 2 years ago. The fan had burnt up and they replaced it under warranty however I had to pay $60 for shipping… then the new one went bad within 6 months. Both of them were always loud. This one, I have to walk up to it to make sure it’s on great quality, good materials and I’ve been very happy so far with its operation.

I know that the Vevor brand is just a distributor brand, but this seems to be a well-built unit, and I've had no issues after 4 months of constant use. The only issue I had was that the couplers don't fit a 4" PVC pipe diameter, so I had to get some 4" PVC Pipe rubber couplers at the big box store to finish the install.
