  •  Do not place the detector in a highly polluted environment (particle concentration > 500ug/m')for a long time; or it may cause damages to the sensor.
  • Do not cover the air inlet/outlet during detections; or let fluff or hair enter the detector.
  • Do not use the detector in humid places or environments with a strong odor to maintain accuracy.
  • Do not disassemble the detector or change its internal wiring to avoid potential damages.
  • Do not use the detector in direct sunlight or facing air conditioner outlets and etc.


Q: Why is the PM2.5 reading not matching with the government departments or other organizations'?
A: The PM2.5 data computed by government departments or other organization are the average data values from multi-monitoring points. Hence it is common that the PM2.5 reading at your place/location is different from theirs.

Q: Why is the PM2.5 reading keeps changing?
A: As PM2.5 concentration in the environment is changing all the time. That not only due ta environment factors like changes in airflow, humidity, wind direction and etc. But also due to common pollutant sources like smoking, cooking, exhaust emissions from vehicles, smoke from burning coal/chimneys/furnaces, etc. All these may influence the PM2.5 concentration and give differences in the readings.

Q: How to understand the changes in PM2.5 HISTORY area?
A: This area shows the changes in PM2.5 concentration over the last 12 hours in a histogram; wherein, the x-axis indicates the time and the y-axis indicates concentration: higher the PM2.5 concentration, higher the v axis (up to 4 segments).

Q: Why is the data reading unstable?
A: As airflow in the environment is changing and the distribution of organic matter concentration may be uneven. Temtop recommends you to try again in low airflow areas.

Q: How to read face icon on the display?
A:home air quality monitor testing

Particulate Matter (PM2.5 & PM10 & Other Particles)

Particle pollution that existed in all types of combustion, including motor vehicles, power plants, residential wood burning, forest fires, agricultural burning and some industrial processes. They can only be seen with an electron microscope and most smaller particles can get into lungs and cause serious potential health problems, while Temtop will shine a light so you can nip the threat in the bud.
