Review on 🔬 Extech CO210 Quality Carbon Dioxide Monitor: Accurate and Reliable Measurement by Seth Damain

I bought this product because I it was having some troubles at work. Until 8:30 a.m. my brain will lack oxygen and I will feel dizzy and ready to pass out. I thought it was carbon monoxide. In the end I couldn't understand why I was sick. I still use this monitor at home. If I work in my office, then until 2:00 p.m. You monitor the beeping, the carbon level is over 1000 - the EPA recommended level. I open the windows and let fresh air in and the readings drop to around 500. I guess most of us don't realize how much CO2 accumulates in your home when the windows are closed or when there are a lot of people overcrowded. . My nephews were playing in my office and maybe after 45 minutes the monitor started beeping. 2 people caused high CO levels. mm.
