Super satisfied with my purchase
The accuracy of the product impressed me, the PM5 and AQI are very close to my area air monitoring station. I went ahead and purchased a couple of them for 3 big areas of my home. It feels nice to know what exactly I am breathing in.
We work in an industrial area, close to a very busy high way, so the level of pollution is way out normalcy. We purchased the PMD 351 because seems the most accurate and professional device we could find for an affordable price. Clearly the results were surprising in the office, but we are taking actions to change the current air situation for the wellbeing of our employees.
Better than I expected
My husband purchased the monitor last week. We were not familiar to this kind of technology, so I started searching for and found that Temtop use Dart sensors to measure formaldehyde which is the best sensor to measure such pollutant in the market. It has been helping us a lot so far.
