Review on 🌬️ BRWISSEN Particulate TVOC HCHO Formaldehyde: Advanced Air Quality Monitor for a Safer Environment by Elvis Bragg

I bought this air quality meter to get reliable evidence that I was exposed to toxic pollutants in my home. When I opened the box I was amazed that this device is small enough to fit on a window seal. Setup is very easy and the on-screen instructions on the device make it easy to understand every feature of the device. I placed the device in the corner of my bedroom because the instructions specifically state that the sensors on the device must be protected from direct sunlight. I turned on the device and it automatically began scanning the air quality in my room. Within 20 minutes the device recorded high levels of PM10, PM2.5 and TVOC in my bedroom. I now have the evidence to show my landlord; thanks to this sophisticated air quality monitor.
