I'm a Realtor.. no. We are not experts on radon. For those who don't know, radon is the #2 leading cause of lung cancer. It's a byproduct of uranium breaking down in the ground. It occurs naturally and disipates into the atmosphere after moving through the ground. When trapped in a basement for example, levels rise and can be toxic. Going back to your question, too many things affect the radon levels. Inspectors do a 48 hour read. The monitor checks every 6 minutes and detects nefarious activity like sellers leaving windows open and messing with the monitor. The levels fluctuate on times of day, weather conditions, time of year (windows are open more in winter), age of home (newer homes are sealed tighter), etc. Over 20 years I've only had this happen recently with new construction as contractors kept coming and going and getting their work done. Nothing nefarious there. I will add as a fun fact, in townhomes, radon mitigation systems need to be installed in ALL the units of a townhome building. If just installed in 1, the mitigation system can actually raise the levels in the 1 because it pulls the radon from the others over to the 1. For more fun radon info, google EPA radon booklet.
This is a long post. Sorry. I want to share my experience.

My mother-in-law never smoked a day in her life. She took pretty good care of her self. Wasn't a runner but walked and ate decently. Maintained a good weight.

Several years ago we had her over for Thanksgiving. She had a horrible cough. We took her to urgent care and the X-Ray looked awful. Further tests confirmed stage 4 lung cancer. We moved her across the state and in with us so that she could have better care. We kept her alive for 18 months where the doctor in her town said she might have had six months to live.

Several months into her stay with us, I started thinking about radon and how much time she spent in the basement. I bought this exact model at full price.

The radon levels were between 10-12 pCi/L. She had spent a decent chunk of those 15 years in the basement, and the HVAC system was spreading it throughout the house at dangerous levels.

I wish that I had bought this years ago. I wish that my father-in-law wasn't so cheap. That he had been proactive. That he did not avoid paying for health insurance so that she could go for yearly checkups.

Lung cancer is a horrible way to die. Devastating. To the victim and to the family. You see them waste away in front of you. Gasping harder and harder for breath. They can't climb stairs. They can't even walk to the bathroom without nearly passing out.

She's gone now. She was 64. It's been nearly three years. My wife will never be the same and I miss her dearly as well.

If you have a basement and you've never tested for radon, please do so. This has been a good device. The deal is half the price I paid. Just buy something. Get your home tested professionally if you don't want the device. This is especially true if you live in an area with radon, but even low-average areas have problems in spots.
I bought one of these about 2 years ago so here's a quick review:

Things I like: Very pleased with purchase, would 100% do it again. Seems to be accurate and provides a little peace of mind. Interesting to watch values rise when the ground gets saturated with rain (as should be expected). We've opened our windows to vent and reduce detected values when they got relatively high many times because of this thing and that justifies the purchase for me. Short term / long term display is helpful. Battery life is phenomenal, I can't even remember ever changing the batteries.

Things I don't like: I can't remember the specs but it only updates a few times per hour. There's no way to set an alarm for high values so you just have to make it a habit to check. There's no way to export info or connect it to a PC to monitor.

Things to know: the sensors in these things are sensitive to vibrations like foot traffic. Vibrations can result in wildly inaccurate counts. Sensor ports are on back, keep them dust/debris free - not just for airflow but because radon can bind with dust and potentially throw off readings. Probably also a good idea to make sure the surface you put it on isn't lead paint and doesn't have some weird extra background radioactivity (ie, post-WWII steel) although I have no proof to offer that this would affect values enough to matter.

What will eventually make me buy a different one: a model with WiFi & alarm notifications.

I own 3 of these and the manufacturer says they are officially operable for 2 years.

I have kept my oldest unit (~3 years) running and tested it against a brand new one. They both are pretty close in radon measurements for short and long term avg.

The same company has had just such a product [airthings.com] for some time. I actually preferred (and bought) the device in this deal some time ago because I didn't wan't something that was app/cloud/Wi-Fi dependent.

When I noticed this price today I went to check to see if it had been posted. I almost considered buying because I loaned mine to a friend last year before he rennovated his basement... and I have yet to get it back. I can say that the readings were very well aligned with professional readings that were taken in my home. This is a great option for those considering a radon solution, or looking for another option to layer in to more regularly monitor an existing radon mitigation system's effectiveness.

Good luck!
Jon

Thank you! That product page says it's still on pre-order so not sure it's been out that long. Love that it has CO2 monitoring too but $299, ouch. Will have to wait until there's deal on it but that is now the exact one I'll upgrade to eventually.

That's the newer model, but they've also had the Wave Radon [airthings.com] and Wave Plus [airthings.com].

Good luck!

Didn't recognize that they technically have a shelf life, not unlike a smoke detector. Great heads up.

Good luck!

I bought this exact model about 2 months ago for around $140 locally. It showed a high Radon level, so I had it professionally tested which confirmed that I had a Radon problem.

For those wondering, a professional Radon test in my area costs about $150-$200 and can be completed by most home inspectors.

Bought 3 of these a few years ago, new, sold by Amazon.com. One arrived clearly used, with protective film removed from screen and battery inserted and measuring the entire time. Amazon is evidently fraudulently selling returned and opened items as "new". Other than that, these devices are very accurate compared to the 90 day test kits I did once a year before.

Most agents will not. Tests need to be done in controlled conditions over a period of time and done with certified equipment by a trusted professional. A real estate agent isn't qualified to do an accurate test.

I have one of these, it's been great! Think I've had for 5 years now and it's stayed solid. We bought a house and the initial radon levels seemed okay, in the 2 range or less. I had this from our old house and kept it out when we moved in. I kept walking past it seeing the numbers climb and within 6 months of being here it was in the 4-5 range!! If I hadn't of used this, I would have never known it was climbing. We have a crawl space so we were told we would need to first encapsulate that first and then install a radon filter. Ughh. So expensive. I was told by a few contractors that sometimes you can get away with just encapsulating and it looks like that was the case for us! After encapsulating, the numbers dropped down to 1-2 again and it's been steady unless we get a crazy rain storm it will go to 3 but drop down pretty quickly again. Very happy with it. I also did a mail in test and the numbers matched our device so it seems to be pretty accurate.

I'm pretty sure this is wrong. It does claim to have a 2 year battery life, which from my experience is accurate. But unlike a monoxide detector, I don't believe there is any reason for it to have a limited life of the sensor. In fact the manual even says it can monitor "over several years".
