Filter efficiency for ultrafine particles:

1. Minimum estimated filtering efficiency, refer to ASHRAE 52.2

2. Dust filtration estimation value, refer to ASHRAE 52.2

3. Assuming there are 10000 ultrafine particles in the inlet air

IAQ issues caused by TSI8525 ultrafine particles in the United States

What do you usually do when someone complains about indoor air quality (IAQ) for an IAQ monitor? Usually, it is necessary to measure indoor temperature, humidity, fresh air volume, and CO2/CO content, and then you may also need to perform measurements such as volatile organic compounds (VOCs), toxic gases, bioaerosols, and suspended particle concentrations (TSP/RSP). Even so, you may still not be able to find the source of the pollution. What is the problem?

Many persistent air quality issues are to some extent related to ultrafine particles. Particles with a diameter less than 0.1 micrometers are usually products of combustion or other chemical reactions. These tiny particles may be generated indoors or outdoors, and their sources include motor vehicle emissions, chimney emissions, industrial processes, battery charging filter leaks, smoking, kitchens, dry cleaners, cleaning agents, office equipment, etc. As far as humans are concerned, different individuals have different effects on ultrafine particles

Solution

The TSI8525 ultrafine particle counter in the United States utilizes the same technology as the TSI Condensed Particle Counter (CPC). The latter has a decades long history of application in particle source detection and recording, and has been widely used in scientific research and industry worldwide.

The TSI8525 ultrafine particle counter in the United States can detect particles with a diameter less than 0.1 microns and count them. It is generally believed that these particles are often accompanied by the presence of pollutants, so the pollution source can be identified through the detection of the TSI8525 ultrafine particle counter in the United States. Whether it is obvious sources of pollution (such as boilers, motor vehicles) or non obvious sources (such as copiers, printers), it is difficult to deceive the TSI8525 ultrafine particle counter in the United States. It can successfully identify the migration of toxic gases, office facilities with pollution problems, production workshops, boiler gasket leaks, and many other issues.
