Incredibly easy to install, and nearly silent when standing a foot away!
I decided to attempt installing my own radon mitigation fan, after discussing this with a few friends who hired professionals and were astounded by how simple the install process was (note: we all had existing passive systems; a full mitigation would likely require a professional). So, I ordered all of the hardware (this fan, a power cord, and couplings for the existing pipe). After connecting the power cord, I went into my attic, cut the pipe in two places, slid the couplings and fan in, tightened it down, and plugged in power. Whhrrr... just a quiet little whir is all I hear when standing in the attic right next to this fan. Downstairs in my home, it's as if nothing is even up there - completely silent. To boot, this fan also consumes significantly less energy than other fans - it is the only energy star certified radon fan, which is important since this thing will be running 24/7 forever. RadonAway has a handy calculator on their website allowing you to easily identify how much money you will spend annually running this thing, and in my case it was less than half the amount of the next-level-up fan I was comparing to. Finally, the thing works. Our radon levels were ~14pCi/L in the basement, ~8pCi/L on the main level. After installing the fan and running it for 2 weeks, I re-tested and our levels in the basement were down to 3pCi/L, and 0.8pCi/L, meaning that this fan is doing an excellent job. Oh, don't forget to buy a power cord for this!

This radon pump is relatively quite, small, has good airflow, easy to install and a good value for the money.

Quiet and Effective Radon Fan
Fan has been running quietly and reliably for just over two years and counting. It brought house radon concentration from above the EPA action limit to well below the limit, so it is effective. As a replacement fan in an existing system, installation was easy and straightforward with a few hardwired connections.

Great Fan
I recently installed a radon mitigation system because of very high radon levels in our basement. This fan worked marvelously for our 2000 sq ft ranch house. It’s quiet and effective. It seems to be of good quality. Be nice if it came with a cord, which is sold separately. Air flow is consistent, fit into designed system easily. All in, the system was about $600.

Easy Replacement
My old RP140 died after 5 years. The last 2 years of its life, it became loud and annoying when I was seated in the room alongside where the fan was mounted outside. In the winter time it was especially loud. It was obvious it was dying. The new one fit perfectly in place of the old one. After shutting off the breaker to the fan, I unscrewed the wire casing and detached the wires from the electrical line. I had PVC clamps holding the fan on at both ends, so once I loosened those I was able to jimmy the fan out from the PVC pipes. A quick replacement of the clamps, rewiring to the electrical line, and it worked like a champion. Replacing a fan in an existing system is probably a 15 minute job if you're home improvement savvy, but still only about 30-40 minutes even if you're not. The new fan is quiet and produces a steady, low airflow. The old fan reduced my radon from 8-11 pCi/L in most places in my basement to 0.8-1.5 pCi/L. Unfortunately, because the electronic radon monitor I have requires re-calibration every year, I don't have a reliable test to check my current levels with the new fan installed. For most homes, this fan should suffice to reduce your radon below EPA recommended levels. However, if your home has very high levels of radon, you might want to opt for a higher airflow fan (such as the RP145), as in a mitigation system, it will suck more of the air from your drain tiles and the soil surrounding your foundation. Bear in mind that the EPA states that any level of radon is capable of giving you lung cancer, but the level where the EPA recommends action is currently 4.0 pCi/L (changed from 8.0 just a handful of years ago). Because the old unit barely lasted 5 years, I couldn't give this 5-stars. I'm hoping the new unit lasts much longer. If you are concerned about your radon levels, test your home. There are cheap test kits out there, and more expensive electronic kits. Or you could call a professional home inspector out to use a professional device. If your radon levels are above the EPA recommended level of 4.0 pCi/L, then you should probably install a mitigation system. However, the two companies that originally came out to give me a radon mitigation estimate both seemed like fly-by-night, unshaven 19-21 year old scam artists that got into this business because it was super profitable, as they charged $1200 in 2008 to install the whole system in an hour and a half (I had the former homeowners pay for it as a condition of buying the house). What does the whole system involve? They sealed the sump with clear acrylic that you can buy at any big box hardware store, and they installed a path of PVC pipes expelling the air out above the gutters of my home with this fan in the middle of it, producing the airflow. That's it. In 2008 there wasn't much regulation for it, and maybe that's changed now and these companies require licensing, etc. But for what they did, any handyman or do-it-yourselfer could do for MUCH less. Disclaimer: Please do not take my review as professional advice. I'm just your average homeowner.

Works great, fairly quiet and easy to install.
Replaced a 12 year old version of this same model. The old one was getting very noisy with a high pitched whine. This one is much quieter. Mine came with only a 2 wire hookup (hot and neutral) with no ground wire. The instructions say this is OK and is expected on some versions of the motor.

Bearings became noisy after a few months
I installed the RP140 to replace another radon fan which was really overkill for the application, and thus was quite noisy. The RP140 was sufficient to reduce the radon level to where it needed to be (I have a monitor) and initially was very quiet. After 3 or 4 months, the noise level increased dramatically - clearly a bearing going bad, similar to what others have reported. I did not even try to warranty it as other reviews have indicated RadonAway will not honor their warranty unless the fan is professionally installed. After another year, the fan has continued to work and seems to be getting slowly noisier over time. I am lucky it is installed where I can't hear it, but I am still disappointed about the quality of the product. It seems silly - installing better bearings would cost them maybe another few cents per unit, and the customers would be a lot happier.

1yr + and still quiet / pulling good suction
Working well now a year and change later.
