The Leading Brand of
Industrial Air Filter

In high-temperature manufacturing processes such as ovens and tunnel sterilizers used in the semiconductor, optoelectronics, biomedical, and precision chemical industries, High-Temperature HEPA Filter plays a critical role in blocking airborne particles and ensuring product yield. However, according to industry statistics, up to 70% of filter failures are not caused by end-of-life conditions, but rather by improper installation procedures. In this article, our professional engineering team from a filter manufacturing company breaks down the four standard installation steps and the key

In AHU, MAU, fresh air systems, and various HVAC air-conditioning equipment, paper frame pre-filters are usually the first line of defense after air enters the system. Their primary function is to capture large dust particles, hair, fibers, and suspended particulates, reducing the load on downstream medium-efficiency and HEPA filters while protecting fans, coils, and the operational efficiency of the HVAC system. However, many air-conditioning systems still experience unstable indoor air quality even when filters are replaced regularly. Problems such as

Recent rodent infestation concerns in northern regions have once again drawn public attention. With reported cases of Hantavirus emerging, environmental management in businesses and factories can no longer be overlooked. In the face of this potentially fatal virus—primarily transmitted through airborne particles—traditional rodent control alone is not enough. Effective Indoor Air Quality (IAQ) management and the implementation of High-Efficiency Particulate Air (HEPA) filtration systems are becoming the final line of defense in epidemic prevention. The Deadly Threat of Hantavirus: How
