Review on 🏠 Elifecity Home Radon Detector: Portable, Battery-Powered, Long and Short Term Monitor by Deron Altman

At first I was very concerned when I first installed the unit. The instructions were pretty clear but didn't say you need more than 7 days for the device to acclimate in the room. In the box was a card showing how to understand the numbers. This device showed more than 4.+ almost 5, which is in the danger zone, but after more than 7 days of tuning. All readings are taken and are still falling daily. Figure 1 is the 7th day and Figure 2 is the total day above and the day below. I'm glad Radon is back and I'm sure I'll be happy with the device even though it runs on AAA batteries.
