Review on BIAOLING Advanced Formaldehyde Analyzer: A Versatile Solution for Recording, Testing, Measuring, and Inspecting Air Quality and Airflow by Andrew Gomez

We purchased this product in August 2017 and 2018 due to air quality issues in western Washington. Global climate change has permanently changed our environment. Forest fires are all around us. In August, these fires made Seattle's air quality one of the worst in the world. We bought an air purifier for our stove to keep the air in the room free of fine dust. It seemed to work, but does it really? So I bought an EG Air air quality meter through Revain. The device works as described on Revain. That's exactly what I wanted to do. So that's a high score from me. I compared indoor and outdoor air quality readings and yes, our indoor air quality was better. As an added bonus, I measured the VOCs (volatile organic compounds) in our bedroom with an EG Air air quality monitor. Usually this is the release of gases into the air from various products. We found that by simply opening our bedroom window when it wasn't smoky outside, we reduced VOCs. Many thanks to EG Air for your product.
