Review on 🎯 Detect & Record: YVELINES Formaldehyde Multifunctional Detector for Indoor Air Quality by Darryl Blumenthal

I am very concerned about the air quality in my home where I have air purifiers in every room of the house. My air purifiers are very high quality and do a great job, but I always check them daily to make sure. I found this where all readings are known and safe ranges are easy to find on the internet where it sits on my bedside table and just looks great there. I have a more expensive laptop and that goes with it, plus the reviews of my air purifier app, good to know too. Very easy to use, fairly fast once calibrated and very easy to see day and night. It's fun to turn off the air purifier and see the numbers change after about an hour. It's nice to know the space is safe and that my air purifiers are working as they should. No cons, works great, very happy with the purchase.
