    Good Value in a home radon monitor.

    In my opinion, the AIRTHINGS Home radon detector is a good value. You can check the hourly fluctuations, as well as the 7 day average and average over the entire time since the last reset. Reset is easy and you get your first reading in 24 hours. I have more than one. The more data, the better for understanding your radon situation. Follow the placement directions, or your data may be flawed.

    Everyone should own one.

    I purchased an Airthings 223 Corentium Home Radon Detector It works very well. I tested it against the free test kits provided by my local health department. They had the same readings. A single use test used when you first move in is not enough. Radon levels change. It gives an average of the past 24 hours, the past 7 days and the past year. I would recommend that absolutely everyone buy one.

    Accurate radon gas readings

    I have used this detector for over a month. The readings that I get with this device compare favorably with two other test methods that were used. The only drawback that I have seen is that pressing the RESET button can cause an error message to appear in the display. Sometimes a subsequent press of the button causes the unit to recover. Also removing the batteries for a few minutes & then reinserting them will recover from an error. I have contacted the manufacturer several times via email & they always respond with helpful information. I feel confident that the radon gas readings that I get are valid.

    Straightforward instrument for measuring radon levels.

    I live in a region of the country (Albuquerque, NM) where radon levels are naturally above the national recommended 4.00 pCu/L. This is a straightforward instrument to setup. As far as using it is quick to setup for measuring short and long term radon levels in an area - just use a paper click to press the reset button. So far in two 7-day reading periods, in different locations, the long term average went down each of the first 3 days. Then it started back up on the 4th day. I am fine with that but since the short term value went up on day 4 the long-term value really jumped higher than any ready during the test period. Thus, make sure to test for a full seven day period as fluctuations up and down can and do occur. The long term value did go back down during days 5 through 7. I am ...

    Peace of Mind is priceless

    One week before buying the Airthings - Corentium Home Radon Detector, I paid a lab for Radon tests of 3 different rooms in my home. The Airthings is matching the lab report results. It's easy to use, easy to set up, and provides accurate information I can move the Airthings from room to room and even test the basement every so often. I like that it shows both short and long term Radon levels. I also took it to our son's house to test the Radon level in his home. I highly recommend the Airthings for anyone concerned about Radon levels in their home. I cannot find any "bad" details to report about this detector.
