3D Printing and Indoor Air Quality: From Invisible Emissions to Measurable Risk
3D printing releases ultrafine particles and volatile organic compounds that are often invisible to traditional air quality metrics. This article explains what is emitted, why PM2.5 is not enough, and how monitoring and ventilation reduce long-term exposure risks. -
Air Quality Science (Part III): Formaldehyde & TVOCs — The Invisible Indoor Hazards
Formaldehyde (HCHO) and Total Volatile Organic Compounds (TVOCs) are among the most common and harmful indoor air pollutants. This article explains their sources, health impacts, international safety standards, and offers practical solutions for homes, schools, and workplaces. By combining source control, ventilation, and purification, we can significantly reduce exposure and safeguard long-term health. -
PMS 31 Remote Particle Counter: A New Choice for Cleanroom Monitoring
PMS 31 is a remote, cleanroom-grade particle counter designed for continuous, in-operation monitoring. Delivering a standardized 28.3 L/min (1 CFM) sampling flow, it improves statistical confidence in high-grade areas (ISO 5 / Grade A/B) and detects short-lived contamination events faster. The instrument is calibrated to ISO 21501-4 for traceable, comparable results and integrates easily with EMS/BMS/SCADA systems via RS485 (Modbus RTU). With long-life optics and...
