Review on 🌬️ High-Accuracy Air Pollution Formaldehyde Detector with Temperature Monitoring by Leon Johnsson

My 6 year old daughter wakes up with a very bad cough around the same early time. A discussion between my wife and I thought it was an environmental issue as it arose shortly after our central external gas heating system was started up. She already sleeps with a humidifier to keep the moisture in the air. We thought maybe there was gas or exhaust fumes coming through the vent. I've searched the internet for a reasonably handy air quality monitor and found this one. I'm no expert, but it seemed easy enough to use and set up. Even if the supplied user manual does not go into great detail, it is enough to get you started. Fully charged, calibrated and ready to see what might cause my daughter to wake up at 3am with a cough. After it worked all night, I immediately checked it the next morning. It showed absolutely nothing but lots of greenery and clean fresh air. No contaminants other than Type 003 dust. I knew I must have done something wrong so I called an HVAC/Air Quality Specialist. He came and checked the house up and down. Haven't found anything either. I showed him my air quality meter that I use and he was happy to let me know that I have a good meter and after looking at the logs he said it matched his results. We're still looking for the cause of the cough, but thanks to the fact that I purchased this air quality monitor from EG EVERHOLD LLC, we know our air is clean and I have a good tool to help keep it that way remains! No problems, no complaints, and if I had any, I'm sure customer service will help right away. The advantage is that you can check the air quality anywhere. Use with the included AC charger or a standalone battery. Either way I'm glad I bought it!
