Seems to work just as well as my 1 year old RadonAway that failed over the winter and began grinding. Will update if any changes happen in the next year.

This fan replaces a fan from 2002 that recently failed. it's outside so noise really isn't an issue but it's pretty quiet, not as quiet as my old one that I had to touch to see if it was on but it just has a quiet hum that you can hear from a few feet away. It came with everything needed to wire it in except the plastic wire connector that fits into the little hole on the outside. I reused the one from the old fan as it fit perfectly. I can't speak for reliability as it's only been a week but so far so good.

Good air flow and very quiet. Typical radon levels have dropped from the mid teens to less than 1.

My old fan could be heard in the whole house. The only way I can tell this one is running is by looking at the vacuum gauge. Very happy with it so far.

Easy to install and comes with the 6-to-4 adaptors and clams, so nice for the end user.No outlet so have to wire the electric part myself, but that's fine I guess the price is on the lower end so it is what I paid for.Noise is pretty high, like an air purifier running in the room at its maximum. Don't pretend you can ignore it because you can't and it is 24/7 on. I installed it in the basement. I would definitely recommend it to be installed outdoor.There is a loud humming noise coming from the end of the discharging pipe, can't figure out how to get that solved still.All in all, 3 stars.

it moves air... works good

My house had radon levels of 2.5 - 4.0 and to be on the safe side I installed this radon fan. Now my radon levels are 0.16-1.05

I bought this fan to replace a 2 1/2 year year-old Radonaway in line fan that was mounted on the outside of my house. The Radonaway fan was always pretty loud but had begun making so much noise that I could hear it from inside of my house. This one is so quiet I have to put my hand on it to make sure that it’s still running. I would buy it again.
