Review on 🎨 Accurate Colorful Formaldehyde Detector: The Ideal Solution for Your Needs by Brian Rivenbark

I get all the numbers. And it was easy to set up. The instructions need more information about what all the dates mean and the writing is so small it took a big magnifying glass to read it. For example, I had to look up TVOC to find out what it means. Also, I don't see an explanation for (1) good vs. (2) good in "environment"; Same goes for (3) pollution vs (4,5,6) pollution but I think the higher the number the worse the environment. Otherwise, it's good to be around and see "OK" blinking! If not, I open the windows and air it out a bit and it's fine again. I bet that pollutants build up in a home over time and the air needs to be freshened up regularly. Good to know!
