Review on Maxmartt Quality Detector Portable Formaldehyde by Adam Hardy

I bought this monitor because I wanted to check the air quality in my small apartment. I found the air quality bad because I was always sniffing when I was in the living room. The monitor worked well and reassured me that the air quality was fine. The numbers rose slightly, but not enough to trigger an alarm. So yes, I am very happy with the purchase and would recommend it.
