Have you ever conducted a home radon test and can you recommend a kit or service?

There are a lot of tests out there and I'm wondering if you have first-hand experience?

I did one with these guys, it's dead simple.

They said everything was fine, but you really just take their word for it, I guess.

I have an Airthing Wave Plus and recommend it.

It has a nice app and syncs via Bluetooth.

There are some existing threads with info for you.
I went with a RadonEye sensor, and now an Airthings Wave Plus. I'd go for the Airthings as it adds CO2 and VOC sensors.

Personally, I'd go with Airthings Corentium Home. No separate app (or device) is needed, and it's less expensive.
Those test kits you can buy at box stores are a one shot deal, and since you really want to test multiple areas at different times of the year to get accurate results, the cost can add up quickly.

You can always get a couple friends or neighbours to pitch in on the purchase of the Corentium Home. Me, being the swell dude I am, lent mine to three of my neighbours and to one family member.

Thanks for linking those threads! I had an Airthings in my amazon cart until I checked here. The sale at Airthings.com is still on and the WELCOME10 code still works! I saved over $100!

(Edited to say I ordered the Wave Plus. All in for $212.61.)

+1 for the Airthings Wave Plus. Picked one up on that sale and it gives a good peace of mind about radon and VOC's in the basement.

Thanks for that. Just wondering if you ever did a side by side comparison between the two devices.
There are some Amazon reviews of the Airthings that question the accuracy of its Radon detection.

RadonEye and Airthings Wave Plus both use the same, certified sensor. Radon readings are pretty close between the 2. Radon level fluctuate very widely, based on temps, airflow, windows open, occupancy, etc. which probably explains why people question the accuracy.
Also, the point of these sensors isn't to know +/-1 bq/m3, it's know if I have 800bq/m3 and need immediate remediation, or if I have 10 bq/m3 or less and don't need to worry about it. In my case, my reading vary from 40-200bq/m3, normally under 100bq/m3 with some basic venting I'm doing. My mid efficiency furnace blows out a lot of basement air out the exhaust, and I also leave a basement bathroom fan running when levels start creeping up.
I hope to install an ERV and run it constantly, and if levels are still not consistently under 50bq/m3, then I'll add a radon sub slab exhaust fan.

Not sure how much you know about the Corentium Home but if you only cared about Radon, would you get the Wave Plus or the Corentium? I get what you're saying about accuracy but if Corentium had a more reliable sensor, I'd prefer that.

I'd still get the wave. It's nice too have the historical charts. Wave and RadonEye both have historical charts. RadonEye can be exported to CSV, but isn't presented as well as the wave. I don't think the corentium has historical charts.
I believe they all use the same sensor. The list is posted in one of those previous threads.

RadonEye plugs into wall, and has a visual display reading. You can also set an audible alarm limit. It connects via Bluetooth but just to download history, not to sync.

Wave is battery powered and only has a colour coded led when you wave your hand over it. But it syncs to your phone via BT.

If you're worried about air quality, you should care about CO2 and VOC. My bedroom CO2 was high, so I took steps to ventilate it.

Where do you place the sensor? I believe Radon is an issue mostly in the basement but it would make sense to have readings where you spend the most time or by the bedrooms?

Check your local library, out here in Halifax I borrowed one of those Air things and it worked perfectly.

I have 2, so I have one in the basement (RadonEye) and one in the bedroom (Wave Plus, since it has CO2 monitoring as well). Levels aren't that different, especially in the winter with everything closed up. If I just got a Wave Plus, I'd try it in the bedroom first to get an idea of radon/CO2 for a month, then move it down to the basement to check there.

Is there any way of telling what specifically is causing the elevated VOC?

You really need to do a process of elimination to determine the causes. In my case, it's not too high, and I'm pretty sure the spikes are due to perfume and cooking.
