RadonAway 23029-1 RP140 Radon Mitigation Fan, 4"

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!

Working well now a year and change later.

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

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.

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.

This was an exact replacement for the same Model # that I installed just shy of 18 years ago. The old fan didn't die, it simply was getting noisier and sounded like the bearings were getting dry. This was one of those replacement situations where you reuse the existing power cord and rubber connections. All dimensions are the same as the unit from 2005. I don't know how long a radon mitigation fan should last, but I'm satisfied with the original lasting 17+ years. That, combined with the fact that every dimension on the new one is the same as the old one, making the installation process a breeze; makes it easy to recommend RadonAway products to others.

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.

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.

This is a short term review (2 weeks use). Unit works great. Had Radon levels averaging 300-350 bq/sqm, installed a discharge vent pipe without fan (passive system) which sadly did pretty much nothing. Once this unit was installed, I let the detector (Air things, amazing unit too) run for over a week to calibrate and give a proper average since Radon level sometimes have great variations. The average over 2 weeks is 15-20 bq/sqm now. Looked around a lot and it is the only unit I've found that seem to have North American certifications and the unit is really well built, not something you'd look at and think "meh it looks cheap so let's hope it work...". At first when I turned it on I thought it was loud, but the unit was really in my face, took 3 steps back and down the ladder, really not bad. Closed the door of the mechanical room and we can't hear it at all anywhere in the house even at night. It's quieter than the well pump, air exchanger and AC/heat pump (and much more quieter than our fridge!). It is important to note it doesn't come with any accessories : no rubber couplings/clamps (4 inches), no power cord/socket grommet or negative pressure reader/meter. It doesn't have any LED or on/off running indicator, you just have to get close to it to hear the humming once plugged (or hardwired, your choice) or install a pressure meter separately. The unit I received only has 2 wires (no ground) instead of 3, which apparently is normal and ok as it is wired that way according to other users and manufacturer's manual. Some people mentioned receiving 3 wires unit which must either be newer/older models I guess, maybe different motor suppliers..? As long as it is internally wired properly, doesn't matter as you have to supply the power cord yourself, so buy the right wire accordingly. Will try and do a long term EDIT in time.

This fan is very quiet, making it perfect for indoor use. If you are a Canadian with a smaller house, who is looking to install a Radon mitigation system, and still want to keep your basement quiet, install one of these! I initially bought a RP145 fan, but that one was pretty noisy to my surprise. Then I decided to try this one (RP140). Even though a RP140 is less powerful than a RP145, it still does the job and brought down my average weekly Radon levels from 150 bq/m3 to just under 15! FYI, I live in a 1500 sq ft townhome that was build in 2021. Pros: - Very quiet - Max power at 20W - Light weight - Suitable for porous sub-slab (gravel or lose soil under concrete slab) Cons: - Does not work properly when connected to generic duct fan controllers - Not powerful enough for larger homes ( > 1600 sq ft) - Not powerful enough for non-porous sub-slab types (e.g. solid clay)

When you spin it by hand you can already hear it rubbing against something. It's already unbalanced! For the money you're asking for this plastic, it should spin without running it on 120V. Good for trash. I'm sending it back to you to bury.

Radon mitigation

Pre pump radon levels where 15 to 17. 2 days after installation I was at 1.5. I used 4 inch pipe with 2 rubber couplings top and bottom fitted to the female end if pipe for a snug fit. Made a wooden platform anchored off the wall . I used automotive rubber fuel line cut into small 1 inch pieces under the pumps mounting housing as insulators. Quiet as a mouse. . Note. Remove the included hardware OUT of the pump after unpacking. I'm sure some people don't even see it in there and then complain about noise after turning it on. For wiring I had a long power chord that I cut off a old power washer . Took a minute to wire it in . Excellent product than runs 24/7. Levels fluctuate regularly but never higher than 2.5 even in cold weather
