Review on 🔍 Accurate Intelligent Multipurpose Real-Time Formaldehyde Detection by Omar Svagera

At the time of writing this article I cannot recommend or disapprove this device as I do not know if the measurements are accurate. It would be useful to have some kind of benchmark or circumstance where the user could test it and evaluate the validity of the readings. So my rating is 3 stars, neutral, out of 5. Also, I need an explanation from the manufacturer why the TVOC value drops to almost 0.000s, say 0.140, after the instrument is on for more than 3 minutes AND no visible change occurred in the measured space. The instrument appears to be more useful for determining which zone (area) the pollutant concentrations are in than for an accurate measurement. However, I am inclined to give this instrument a higher grade after receiving an explanation as to why the VOC levels are noticeably decreasing. You can find much more information with measurement charts in different situations in my post on ppiahomes.com. One caveat: The International Well Engineering Institute recommends formaldehyde levels below 0.036 mg/m3, not 0.100 mg/m3 as suggested by the manufacturer. Specifically, the institute recommends that the HCHO content should be below 27 ppb. I estimated 0.036 mg/m3 with a WHO molecular weight of 30.01 g/mol HCHO. The Institute also recommends VOC levels below 0.500 mg/m3; for PM2.5 below 0.015 mg/m3 and PM10 below 0.050 mg/m3
