Not medical advice." --- # Airthings Corentium Home 2 vs. View Radon vs. View Plus All three are consumer digital radon monitors: they measure radon continuously while they have power, so you can watch levels change.[^1] They don’t replace a lab test. CRCPD says to verify a consumer monitor’s results with an approved test, and never to use one in a real estate transaction.[^2] Vermont Radon earns a commission if you buy through our Airthings links, at no extra cost to you. We haven’t tested these monitors; everything below is Airthings’ own published information or official guidance.

Airthings says it can be used as a standalone device without any wireless connectivity.[^3] - **View Radon:** if you want to check readings in the Airthings app over Wi-Fi, on a larger ePaper display.[^4] - **View Plus:** if you also want particulate matter (PM2.5), carbon dioxide, airborne chemicals and air pressure, along with radon.[^5] ## What official sources say about all three - CRCPD: the accuracy and reliability of consumer digital radon monitors have not been verified by an independent third party, and results may be higher or lower than actual radon levels.[^2] - CRCPD: they are not for making radon mitigation decisions; long-term testing is advised for that.[^2] - CRCPD: because monitors may lose accuracy over time, verify radon levels periodically using an approved method.[^2] - Professional listings: as of October 17, 2026, NRPP’s and NRSB’s approved-device lists include Airthings’ Corentium Pro, not these three consumer models.[^6][^7] ## Start with the lab test, add a monitor if you like Order the Health Department Lab’s long-term kit for $25[^8] and leave it in place for 3 to 12 months, ideally including a heating season.[^9] **Want to see levels day to day?** A digital monitor measures and records radon continuously while it has power.[^1] Use it alongside the lab test, not instead of it: CRCPD says to check a consumer monitor’s results with an approved test.[^10] [Order the $25 long-term kit](https://vdh.webapps.aidcvt.com/water_supplies/radon) [See Airthings monitors](https://discount.airthings.com?aw_affiliate=eyJjYW1wYWlnbl9pZCI6IjEiLCJ0cmFmZmljX3NvdXJjZSI6InZlcm1vbnRyYWRvbi5jb20iLCJhY2NvdW50X2lkIjoyNDI1N30) (Affiliate link) If you buy through the Airthings link, Vermont Radon may earn a commission at no extra cost to you.
