My Daughter has a radon remediation system in her basement. How do you know it's working without sending off tests in the mail?. This device is constantly giving you the radon data. She loves that I gave her this because her children play there all the time Great product!

I can't speak for accuracy. Our radon levels have been high and low. Thanks to this device we are adding a radon mitigation system in our home. Radon level upstairs go from .16 to 2.10. The basement had a 4.48 and it also varies with reading from 1.08 and up. Anything from a 2 to a 4 EPA recommends the radon mitigation system. The radon tech said one reason is because they poured cement two different times in our basement leaving a crack for radon to leak in. This time of the year they don't normally see levels like ours. Normally winter months are the worst. This is not an old house it's brand new. Radon tech did say this is a good unit for a consumer. He accepted my reading from it. I fully trust this radon detecter.

I was getting a bad cough and sore throat, and lung pain, when I would go down in the basement. Friends suggested it was mold, but u had someone test and no mold. I got the thought that it maybe it might be radon. This little monitor was ringing off the hook after I plugged it in and after doing some research in my area, I was able to get a mitigation system. In my basement. It only took a few hours and cost $1695, with a lifetime warranty on the system (and $5 year warenty on the fan). Immediately my numbers went down by about half (though they said to allow a full week to judge it). But that was still high for me and while I felt immediately better, I still felt sick in the basement). They came back again and added a second system (tying it into the first system for $600 more) and I felt completely fine ðŸ'🎉 and my numbers went down to under one. (Note my house square footage is about 2000 square feet and only about 750 square feet in basement).
I highly recommend this device. I found that prior to getting my mitigation system, when I felt more sick in the basement I would check the numbers and they would be spiking and when I felt less sick they would be lower. I got to the point that without looking at the monitor, based on how I felt I could pretty accurately guess what the reading was going to say.
It is said that radon gas is odorless, tasteless, colorless, but their are signs if you are synced into your body you might be able to feel it.
Don't fear getting a mitigation system, it was relatively cheep compared to the cost of my health and is barely noticeable on the side of the house.

This device gives me peace of mind. Just knowing that I have a visual of the levels on a daily basis. I had a radon specialist to do an evaluation of the level readings and this device. He highly recommended this device over doing the charcoal test that has to mailed to a company to be tested. I purchased To measure radon levels in the basement.

Seems to be a nice detector. So far in the evenings the radon level goes up. Seems to be pretty in sync with another brand I currently own. Only difference is this one can tell the level in 10 minutes. It is really nice because then can take it to your friend's house and check theirs in only a few minutes rather then having to keep it there a couple days. Easy to set up and understand the reading. I am glad I bought this device.
