Help protect your home with this smart radon detector — it's 30% off during Amazon's Winter Sale

This year, a lot of people have made resolutions to be healthier overall. An easy way to do that is to keep an eye on your indoor air quality. Low air quality can lead to sore throats, headaches and other unpleasant effects, according to the EPA. Another concern is radon, an odorless, colorless gas that can cause health problems over the long term — and the EPA thinks one out of 15 homes has levels that are too high. How can you know? Easy: with the Airthings Wave Radon Detector, now on sale for $114 for Prime members.

Why is this a good deal?

At nearly 30% off, this is a fantastic deal if you want to keep an eye on your home's air quality. Even if you aren't a Prime member, you can still pick it up for just $120.

Why do I need this?

The Airthings Wave is incredibly easy to use, even if you're the most non-tech-savvy person on the planet. All you have to do is wave in front of it, and it will tell you at a glance how your air holds up. A green light is good, yellow is a warning, and a red light means the radon levels are dangerously high. By downloading the app, you can get more detailed data on your air quality.

The Airthings Wave also keeps an eye on temperature and humidity, too! The app is free, so you don't need to pay a subscription to get more information. So what should you do if your home does have high radon levels? Airthings suggests monitoring for a month, and if levels don't decrease in that time, calling a professional.

You should also check out an air quality monitor just to keep an eye on allergens and other pollutants, but most of those monitors don't pick up radon levels. A two-pronged approach is the easiest way to ensure your home air quality is up to snuff.

What reviewers say

"Suspecting I had a radon issue, I purchased this detector and let it run for a month. Based on elevated radon readings, I went ahead and got a radon fan installed. I was then able to watch the radon levels go down day after day, week after week to confirm the fan is working. I recently lost power for 12 hours and observed the radon levels went up again for those 12 hours before power was restored, then they went down again," one user wrote.

Another shopper shared that the battery life is outstanding. "Easy to set up and easy to monitor. The values were in line with other tests performed and the app works great. I get notifications on my phone that are color coded as well as being to check the color on the device. Battery life so far is excellent. I am several months in with the original batteries still going strong."

"I would buy again," said one customer. "Easy to install and easy to read. The app is easy to use also. Highly recommended."
